HAVING carefully considered the phenomena of nature, and studied for years the great questions and problems of science, and come to conclusions and formed theories in many respects very different from the commonly received opinions of the age, I have thought it fit and proper to present my views to the consideration of my fellow-citizens, in the hope-perhaps a vain hope-that they may awaken inquiry upon the subjects referred to; and be productive of good. I am well aware, that in presenting views and theories in matters of science, different from those thiat are sanctioned by high authority-entertained by great numbers of men of science, and taught in the highest seminaries of learning, I shall subject myself to se'ere, and perhaps harsh criticism; but knowing also, that false assumptions and erroneous theories lead to fallacious reasoning and wrong conclusions, an unmanly fear of criticism shall not deter me from an honest effort to aid in promoting an increase of useful knowledge among men. The mystical philosophy in relation to heat, light, and a supposititious luminiferous ether, which has recently crept into science, and also much of the doctrines in relation to the correlation of the forces, ignore the real forces of nature, as well as the spiritualism of the Bible, and tend directly to Materialism and Pantheism. I have endeavored to combat as unsound, the solar emission theory, as well as the vibratory-ether theory of heat and light-the chemical theory of combustion-the chemico-mechanical theory of life and organ iv PREFACE. ization-and the material, or chemico-mechanical theory of mind; and have presented as worthy of consideration, the old material theory of caloric-the attraction theory of light, and of the action of caloric-the terrestial theory of the sources of caloric —the calorific theory of ignition and combustion-the vital theory of life and organization-and the spiritual theory of mind. By spiritual theory of mind, I mean the Christian theory-not the theory of Andrew Jackson Davis, and the spirit rappers. The terms spiritual, spiritualism, and spiritualist, are used in contradistinction to the words material, materialism, and materialist; and in that sense, every Christian, and every person who'believes in the immortality of the soul, is a spiritualist. The use of the words spiritualism and spiritualist, by spirit rappers-pretending to have communication with the spirits of the dead, is a modern abuse of the wordsresulting from delusion and false pretenses. Much of my reasoning, and of all human reasoning, in relation to the phenomena of nature and of mind, and the causes and *forces which produce them, is necessarily based upon inferences and assumptions of causes and forces, which are beyond the reach of our senses, and also beyond the reach of scientific investigations and tests-and are matters of inference only; but, as effects and phenomena can not be produced without adequate causes and forces, every person who reasons upon such subjects, must infer some cause for them-the principal difference between my mode of reasoning and that of other scientific reasoners is, that my reasoning is based upon one set of inferences and assumptions, while theirs are based upon other sets-each class or school of scientists and philosophers, having their reasoning and views based upon a class of inferences and assumptions peculiar to themselves. Different men take different views from different standpoints, and draw different conclusions, from the same facts and evidence. Perhaps the question may be asked-who is Mr. S., that he shlould question the soundness of the opin PREFACE. V ions and theories of the most scientific men of the age, and presume so much as to present to the public the peculiar views and theories of his own in matters of science? Is he a practical chemist, geologist, or engineer-a distinguished professor of physics-or has he experimented extensively in any branch of natural science? Nothing of the kind is pretended. But while I do not claim to be learned in the details of any of the natural sciences, I do claim to have observed and studied carefully the general laws of chemistry and physics, of the vegetable and animal economy, of the forces of nature, of dynamical geology, and the philosophy of mind. I have made law and power, cause and force, the study of a life time. And though I have made the laws, usages, and customs of man, and the practice of courts of justice, in connection with human rights and natural law, my principal study; yet I have studied with great care, the subject of intellectual and moral, as well as political and physical force aLd power. I have carefully observed the phenomena of nature-observed and studied the experiments in Nature's Great Laboratory-and read and considered great numbers of the experiments and views of practical chemists, physicists, and men of science, and witnessed many of their experiments. I think, therefore, I am as well qualified to form opinions and theories of the elements, forces, and laws of nature, and of the causes which produce the phenomena of nature and of mind, as I should have been, if I had practised in chemical laboratories, and lectured on chemistry, geology, or physics, for a quarter of a century. I think the work will be tound to have at least one merit-that of definiteness, clearness, and freedom from vagueness and mysticism, in its assumptions and its inferences, as well as in its statements and argumentsso that the reader can comprehend my meaning, and understand my views of the forces which produce the phenomena of nature and of mind. If it have that merit, others can see and distinguish its errors from its truths, and point them out. vi PREFACE. In the preparation of this work, I have become indebted to numerous authors, for materials and facts, as well as for views and arguments-but more especiallytto Prof. Tayler Lewis, whose writings have aided me more, than those of any other living man, in the formation of my opinions. Let no one be deterred from the study of natural science, because he is wanting scientific apparatus and the means of experimenting. Books on science and Nature's Great Laboratory, will furnish sufficient materials and experiments, for study and contemplation. With such views and purposes, the following pages are respectfully submitted to the consideration of the public. E. C. S. ANN ARBOR, MICH., March, I873. CONTENTS. CHAPTER I.

GENERAL VIEWS OF MATTER AND SPIRIT-THE DIFFEREXT MODES IN WHICH THEY ACT, COMPARED AND CONTRASTED. THE origin of matter, and the mode in which it was created or came into existence, are beyond the domain and scope of man's knowledge and power to investigate. Even the development theory does not attempt to account for the origin of matter —but takes the universe as it is, and from the evidences of change in the crust of the earth, infers that the vast and innumerable systems of worlds, which constitute the universe, have been developed from a nebulous state, and that animal and vegetable organisms have been developed from its elements. Man can know nothing whatever of the origin of matter, except from Divine revelation-and nothing of its properties, except what can be deduced and inferred by human reason, imperfect as it is. Hence all human reasoning and science, except whlat relates to abstract numbers and quantities, must necessarily be more or less defective, imperfect, and uncertain. It is difficult for man to form or have any clear conceptions of the nature and characteristics of either matter or spirit, or of the differences between them, without first analyzing and ascertaining their modes of action, and contrasting the action of matter with the action of mind. Their nature and characteristics we can determine only by inference from their action. By spirit, I mean not only the Divine Mind, but also a principle of intelligence, so blended in man with the organization of the brain, as to form the human mind. It constitutes the power of consciousness, the power to take cognizance of external things - 2 MATTER AND SPIRIT. -the power of thought, and of action. For aught we know, it may emanate from the Supreme Being. So far as intellect or mind is concerned, the starting point of all human reasoning must be intuitive cognizance, and human consciousness. So far as matter is concerned, our knowledge of it must depend upon the limited powers of the human mind to take cognizance of the almost infinite minuteness of the atoms of matter-altogether beyond the reach ot the senses, even with the aid of the microscope, and any instruments which man can invent-and must content ourselves with observing aud studying matter a,.d its action, in its combinations and masses, and must infer its properties, forces and powers, from its action, and from the phenomena of nature. The theories we form, and our processes of reasoning, should be corrected at every step, by comparing them with the phenomena of the world, and of the universe. Matter is moved and controlled in its action, by its affinities for other matter, and by the affinities and attractions of other matter for it-whereby atoms and elements of matter mutually act upon and attract each other. Tile affinities of matter form the principle of universal attraction-which, deriving its powers from the inherent properties and forces of matter, acts with uniformity as a secondary power in the government of the universe. On the contrary, spirit or mind is not controlled by its affinities, but by intelligence and volition, to attain some end or purpose. Matter can act only in accordance with its affinities; and under given circumstances it can act only in one mode. It always acts ex necessitate, and must act in accordance with its affinities, and the affinities, powers of attraction, and local position of the elements and bodies of matter acting upon it-having no power to resist or refrain from such action. On the contrary, mind, and especially the Divine Mind, does not act from necessity-may act or refrain from acting, and is not constrained or impelled by its nature, affinities, or. condition, to act in any particular rhode —but MATTER AND SPIRIT. 3 may exercise creative power, conservative power, or any other power, in any mode, and for any purpose, in accordance with its arbitrary purpose and volition. Man must attain the elements of knowledge mostly through the senses, and through his own consciousness and feelings, appetites and wants; whereby he is governed mostly by his physical wants and appetites-but within a certain narrow sphere, the minds of men, and especially the higher orders of the human intellect, act in accordance with their own arbitrary volition, and are not controlled in their action by external things, nor by any fixed or definite modes, forms, or rules of action, as matter is. This independence of mental action is especially manifested in the exercise of the inventive faculties —in experimenting-and in studying the order and laws of nature, and tracing the relations between cause and effect. The. affinities, powers and forces of matter, act with uniformity; but mind does not act with uniformity. Two minds seldom act precisely alike. Matter is always affected in the same manner by physical causes; while mind is often quiet under the most powerful influences; and what excites one mind, does not disturb another, under the same or very similar circumstances. Mind often acts whimsically, arbitrarily, and from mere fancy, in search of novelties and new thingswhile matter acts with uniformity, and in accordance with law. Though the intellect is so mysteriously blended with the organization of the brain and nervous system that neither the chemist nor the anatomist can detect it, yet the manifestations of its influence and power are so great and various, and the consciousness of its action so clear and vivid, that it requires a strange degree of incredulity and skepticism, to doubt its existence as a real entity, distinct from the elements which form the brain. Human action, considered in connection with the condition of a dead body, clearly indicates that the living brain contains two elements-an 4 MATTER AND SPIRIT. intellect, as well as a living principle, not contained in a dead one. Intellect is distinguished from matter, and put into a class called spiritual-not because it is not substance-not because it does not possess many of the properties of matter, hut because it is endowed with the powers of consciousness and intelligence, and is exempt from the chemical affinities and other properties by which unintelligent matter is governed. Mind or spirit is called immaterial-not because it is not substance, but because it is not controlled by the affinities, attractions and properties, by which all the elements of the material world are governed. God is a spirit, but has never been represented by any intelligent person as not occupying space; on the contrary, the Divine Being is represented by Christian theologians, as filling, to a large extent, the infinity of space. Moving Powers, or Forces. Every change, movement and action in the natural world, as well as in the animal kingdom, requires a moving power, force or cause, to produce it. The forces of nature consist of the attractions of the elements of matter for each other. The force of spirit is a power inherent in intellect to originate action, and to act of itself as a cause, guided by its own intelligence and will. Intellect is self-acting, and can act without being propelled by external influences. Unintelligent matter acts very differently, and can act only when moved by spirit, or when two or more elements mutually attract each ofher. No mechanism can be so constructed and arranged as to move itself, without a moving power, derived from the forces of nature. The moving power of a watch is its mainspring. Every machine must have a moving power to operate it. So with animal and vegetable organisms. They must have a motive power to operate them —a power very different from the inherent properties and powers of the ponderable elements of MATTER AND SPIRIT. 5 which their organs are composed. The motive powers of vegetable organisms, are the vital principle and caloric; and the motive powers of animal organisms, are the vital principle and caloric, electricity and intellect. Perhaps caloric and electricity should be regarded rather as stimulants, than as motive powers, though caloric is as necessary to vital action as the vital principle itself. CHAPTER II. ELEMENTARY SUBSTANCES, AND THEIR GENERAL PROPERTIES —MECHANICAL, OR MOTION AND FRICTION THEORY OF HEAT-PECULIAR PROPERTIES AND ACTION OF CALORIC, ELECTRICITY, MAGNETISM,. AND THE VITAL PRINCIPLE. Elementary substances. CHEMISTS have succeeded in decomposing and analyzing many compounds, which were once thought to be simple elementary substances, until they now recognize in nature, more than sixty different elements or classes of atoms-each having properties and affinities peculiar to itself-which differ from those of every other element of matter. Oxygen, which forms a part of water, of atmospheric air, of rocks and stones, and of all animal and vegetable organisms, constitutes the most abundant element in nature; while caloric, or fire, the basis or cause of the sensation of heat, is the most universally diffused of all the elements of the universe. The smallest division of any element of matter is called an atom. The atoms of many of the elements, and particularly of the metals, have a strong affinity for each other, which causes them to unite and adhere together, by what is termed the attraction of cohesion -which is much stronger in iron, than in any other element or combination of elements. When different classes of elements combine (as oxygen and hydrogen to form water), the attraction or force which brings the atoms together and holds them in combination, is called chemical affinity. The lowest combination so MECHANICAL THEORY OF HEAT. 7 formed is called a molecule; the lowest combination of atoms from which animal or vegetable life can be developed, is called a germ. The chemical affinities and gravitation are not distinct elements of matter, but mere forces inherent in and constituting properties of matter, which cannot be separated from the matter of which they are properties; but in addition to them, there are certain subtle elementary substances, which, in common parlance, are called forces-on account of their extreme mobility and power, and their peculiar affinities and action. They are caloric or fire, electricity, and perhaps magnetism,which mav,or may not be identical with electricity. To that list I shall add the vital principle-as a distinct element of matter-believing it to be an organizing element, which attracts, unites, and forms certain elementary substances into germs and cells, and living organisms, and finally moulds them into plants and animals. AMechanical, or motion andfriction theory of heat. A theory was fortned more than two centuries since,.that caloric or fire, the element of heat, is not an element of matter, but th4 mere effects of matter in motion. That theory was suggested by the fact that heat and flame can be produced, and a fire kindled with combustible materials, by means of friction-by rubbing together two sticks of dry wood-or by striking a flint stone with steel, over tinder or gun-powder. It is also well known that heat is produced by the friction of machinery-by wheels running swiftly over an axle; and it has been observed in boring cannon. The theory obtained very little credence until a comparatively recent period; and very likely it would have sunk into oblivion, if it had not been supported by the distinguished name of Lord Bacon. It is difficult to account satisfactorily to many minds, for the production of heat and flame by friction; and during the last fifty years, the theory in question has been re t~8 MECHANICAL THEORY OF HEAT. vived, and so elaborated, that it is now believed and maintained by great numbers of scientific men. But it should be borne in mind that the quantity of heat produced by friction is very small, and generally by a very slow process. Perhaps fifty times as much heat can be produced by burning two sticks of dry wood, as by rubbing them together for half an hour. It has been suggested that the heat p;roduced byfriction is caused by the caloric pressed out of the wood or metal, or out of the atnospheric air surrounding them, at the place of friction and compression. That explanation seems to my mind more consonant to reason than the theory that heat is produced by motion-for the theory assumes that heat and flame aire produced by motion only, without even friction-except such firiction as may be produced by the motion of a solid body moving through atmospheric air-or by the internal motion of the atoms of iron or other metal in a heated furnace or crucible-or by the motion of a supposititious ether contained in such metals. I think it may be truly affirmed, that heat is never produced by motion alone, nor without friction with something more dense than the atmosphere of this earth. Experience shows, that it requires the friction of two solid substances, and the compression of such friction, to proJuce heat and flame; and the heat then produced is very trifling —though it is sufficient to fire gun-powder, or tinder. The only way to produce fire or heat to any great extent, is to communicate fire directly to dry wood, coal, oil, gas, or some other comcombustible material, and thereby produce combustion, and set free the caloric contained in the materials consumed. The friction theory of heat overlooks the obvious general causes of combustion and heat, and fixes upon the mode of their origin in occasional cases, as their cause. It is very true that combustion and a blaze may be produced with dry combustible materials, by friction-but they are not often so produced. They are generally produced by the direct agency of fire, as the cause. Before the invention of MECHANICAL THEORY OF HEAT. 9 fiiction matches, fires were kindled perhaps a million times, by the direct agency of fire, where they were once by friction; and when a blaze is once produced, friction is never necessary to the propagation -and contitnation of combustion. Caloric is developed by combustion-which spreads, and propagates, and continues the combustion; but when a blaze is produced by friction, it is propagated, not by friction, but by the caloric developed and set free by combustion. It was known more than fifty years ago, that heat and fire can be developed from atmospheric air, by compressing it, but the reisoning of Count Rumford in relation to the development of heat by friction, indicates that he was not aware of that. philosophic truth. Prof. Amos Eaton, wlho was professor of chemistry and natural philosophy in the Rensselaer School at West Troy, N. Y., in his Chemnical Instructor, publishled in IS26, in a note (page 27), says: "Some chemists consider heat as the effect ot a vibratory motion in the particles of matter. This hypotheses is chiefly founded upon the fact that a flame may be excited and continued by friction, greatly disproportioned to the combustible substances consumed. If a stick is put in the state of rapid motion in a lathe, and another stick held against it, a great flame will be produced by the compression of' the air, which is forced between the sticks by this rapid motion." Again, in a note (p. 39), he says: "I have treated caloric as a material fluid; which I suppose I may now venture to do, since Professot Hare has had the imloudence to demonstrate the absurdity of Davey's vibratory theory. See An. Jour. Science, vol. 4, p. 142." In the article referred to, Prof. Hare says: " How inconceivable is it that the iron boiler of a steam engine should give to the particles of water a motion so totally different from any it can itself possess, and at the same time be capable of such wonderfuil eflects, as are produced by the agency of steam." IO CALORIC, A SUBSTANCE. Caloric orJfre, an element of matter. The fact that fire or caloric expands iron and all metals, wood and all solids, atmospheric air and all gases, and so expands water as to convert it into steam and vapor, furnishes conclusive evidence that it is a distinct elementary substance-having the properties of extension and resistance, and occupying spacelike the ponderable elements of matter. It must expand solids and liquids by permeating them —entering between the atoms of which they are composed, separaling them, and pushing them asunder, very slightly. Such effects are not consistent with the theory that what we call fire is.only the effect of matter in motion -a mere vibratory movement of a subtle ether, or other matter. The phenomena attending the great fire in Boston, which commenced in the evening of November 9th, 1872, and the report of the Observer of the Signal Service of the United States at that place, serve to show the material character, as well as the action and great power of fire, or caloric. The report is as follows: Boston, Nov. I3th, I872. To the Chief Signal Officer of the Army, Washington, D. C. General-In reply to your telegraphic dispatch received this morning, directing me to make a ifull report of the meteoric phenomena attending the recent great fire, I would respectfully say: The wind at this station during the progress of the fire, varied from north north-west to north, with a velocity of from five to nine miles per hour-the weather being clear, cool, and pleasant. On approaching the fire on the north, or windward side, as close as the heat would allow, the draft of air through the burning streets assumed the character of a brisk wind, probably sixteen or eighteen miles per hour, while the heat was so intense as to cause the smoke, steam, etc., to be carried up in spirals, to a great elevation. On the south or lee side, the induced currents of air were very strong, probaply thirty to thirty-five miles per hour, carry CALORIC, A SUBSTANCE. I I ing the fire bodily to windward. This state of affairs appears to have been the reverse of the Chicago fire, where the strength of the wind was sufficient to overcome the induced current, and the fire burned to leeward. It appears as if the hiih wind permittedthe indraught to raise at a considerable angle, after reaching the fire leaving a large space of highly rarified air in its front, inducing stronger currents to flow, which, meeting the indraught, gave a spiral or whirlwind motion to the ascending current. During the fire a flock of ducks passed at a great height overhead, and the light reflected from their plumage made them appear as fire balls passing rapidly through the air. Many who saw them called them meteors, and likened them to balls of fire said to have been seen in the Northwest, during the great fire in that region. As an example of great heat diffused, I would state that during the night I exposed a thermometer in the observatory to the fullglare of the fire, when it rose nearly five degrees, although placed upward of 2,000 feetlfrom the burning district, and dead to windward of it. No other phenomena occurredthe barometer rising slightly, and the weather remaining unchanged. I have the honor, etc. (Signed) H. E. COOLE, Observer Sirnal Service U. S. A. Such were some of the meteorological phenomena of the great fire of Boston. The combustion of buildings and goods produced such an ocean of flame, and set free such a prodigious amount of caloric, that the caloric diffused itself in every direction for a great distance-heated and rarified the whole atmosphere in and around the city-induced strong currents of inflowing air from even the leeward side of the firegave an upward and spiral motion to the whole atmosphere in, around, and over the city —and sent it up to a great elevation-and so permeated the air and diffused itself, even in opposition to a strong wind, blowing at the rateof from five to sixteen miles per hour, 12 CALORIC, A SUBSTANCE. that it raised the mercury in the thermometer nearly five degrees, at a distance of three-eighths of a mile from the consuming flames. Will any one pretend that such phenomena and effects were produced by the mere motion of ether, or of any other element or thing -without the agency of any such elerrent of matter as has been for centuries called fire, or caloric? What but such a subtle element of matter as caloric has been generally understood to be, could permeate the whole atmosphere-move in every direction —contrary to a strong wind as well as with it, and in such quantity as to raise the temperature nearly five degrees, at a distance of more than 2000 feet from the burning buildings? Fifty years ago caloric, electricity, and light, were almost universally recognized by chemists, and very generally by natural philosophers, as distinct elements of matter-though they were classed as imponderable snbstances. All the other elements recognized by chemists, were classed as ponderable substances-because the latter classes all tended to gravitate towards the centre of the earth, and can be weighed in scales, and their exact weight ascertained-while caloric, light, and electricity, have no such gravitating tendency, and therefore no weight. Though the whole earth as a body has a gravitating tendency towards the sun, as the centre of the solar system, by reason of the sun's power of attraction, and the affinity and power of attraction of the matter of which the earth is composed for that of the sun-yet the atoms, elements, and compounds of the earth, have so much stronger affinities and attractions for each other, (that are in immediate proximity or nearly so), than for the sun, which is millions of miles distant, that they gravitate strongly towards each other and towards the centre of the earth, and to a comparatively trifling extent towards the sun —while electricity is so subtle and mobile, has such peculiar affinities, and moves from the earth to the atmosphere with as much facility as from the atmosphere towards the earth, that it has no such gravi CALORIC, A SUBSTANCE. I3 tating tendency towards the earth as to give it any appreciable weight; and caloric is so mobile, and has so much stronger affinity for the sun than for the earth, that it is constantly drawn by the sun's attraction from the-side of the earth turned towards the sun, into the atmosphere —though that great source of attraction and power is more than ninety millions of miles distant fiom the earth. Hence, caloric has no weight, and is properly classed as an imponderable element. Light I can not regard as an element of matter, distinct from caloric —but consider the sensation of light as produced by the attractive force of calorieoperating directly upon the optic nerve of the eyeas is hereinafter explained. Those who deny that fire or caloric is a distinct element of matter, and insist that heat is only a mode or form of motion, are driven to the necessity of assuming the existence of an elastic fluid pervading the universe, which they call ether; the action of which, in different modes, and under different circulnstances, constitutes both latent and sensible heat, light, and electricity. It is beyond the power of man to prove or disprove the existence or non-existence of such a supposititious ether —fir it is heyoid the reach of the senses with the aid of the microscope, and beyond the power of the chemist to detect. It is therefore a pure assumption or hypothesis-without proof, or the possibility of proof to sustain it. On the contrary, caloric, or fire, may be so concentrated and accumulated as to produce light, and the eye can see it; and whether free or latent, it operates upon the sense of feeling, and may be measured by the thermometer. It was known and tolerably well understood before the age of chemistry, and when nothing was known of ally of the other simple elements of matter except a few of the metals-and when it was not known that even the metals were distinct elements of matter. Nothing was known of the component parts of air or water, earth or rocks, plants or animals, of oxygen or hydrogen, nitrogen or carbon, until late in the i8th 14 PROPERTIES OF ELECTRICITY century; and yet the element of fire, and most of its properties, were well understood. Electricity. Electricity is the most In(bile of all the elements of the material world, of which we have any knowledge. While caloric always moves comparatively slowly, electricity often moves with wonderful velocity-as is shown by the operations of the electric telegraph. Though much is known of the action of electricity-mnuch is unknown of its action, as well as of its nature and properties; and there is still a dispute among chemists and natural philosophers, whether it comprises towo different fluids-a positive and negative fluid, or only one. It is diffused through the atmosphere and the crust of the earth-is present in all living animal organisms and vegetable substances; and there is reason to believe that it is the agent of the brain and nerves, to aid in commnnicating volition from the brain, and sensation to the brain through the nervous organization-but that is not susceptible of proof. There is reason to believe that caloric is generally so combined and blended with electricity, that the two act together. Either caloric is blended with electricity, or else the latter has some of the properties of the former, which enable it to emit a spark, and to generate combustion in materials that are dry and combustible. The fact that the electricity in the atmosphere is in a quiescent state, during the cold weather of winter, when it contains very little caloric, indicates that the two act together, and that the electricity does not show itself, because there is not sufficient caloric in the atmosphere to give it activity. The fact that lightning often makes visible marks upon trees and buildings, ond sometimes rends them in pieces as effectually as if it were as solid as a cannon ball. furnishes irresistible and conclusive evidence of its material character-and shows that it is a sub THE VITAL PRINCIPLE. 15 stance, and not a mere vibration or force, without substance. Magnetism.. Magnetism is in many, if not all cases, blended with electricity; and less is known of its essence and nature, than of any thing in the vocabulary of chemistry. There is reason to doubt that it is a distinct elementary substance. The experiments with electromagnetism give reason to believe, that magnetism is only a imode of action of electricity. The vital element. Chemists have not recognized the vital element or living principle, because they are unable to collect it and confine it in their glass jars, as they do electricity, the gases, and all the grosser elements of nature; but physiologists, physicians, and writers on medicine, have very generally recognized it as the organizing principle and basis of life-without which it is impossible to account satisfactorily and rationally, for vegetable and animal organisms, and their development and growth. Believing that there is such a substance in nature as a vital organizing element, which attracts, unites, and holds in combination the various elements of matter, which compose animal and vegetable organistns, I class it as one of the elementary substances of nature. Though we can know nothing of it except from its effects, its existence as well as its irnponderable nature, is shown, as intellect is shown, by its effects, and by the manifestations of its power. Its organisms, by means of its power, collect from the earth and the atmosphere, food and materials which they form into the sap of trees and plants; and it raises the sap from the roots, and carries it up through sap vessels or tubes' into the body, limbs and leaves, converts it into fibre and leaves, and thus sustains them, and causes their development and growth. All of which I6 PROPERTIES OF CALORIC. is done, in antagonism to the laws of gravitation, and generally in antagonism also to the chemical affinities of the elements and compounds, thus raised and assimilated. It also constitutes the healing power of nature. Such manifestations of power should be sufficient to satisfy any rational mind, of the existence of a living principle, as a distinct element of nature The subject hqis been more elaborated by Dr. Martin Payne, of New York, than by any other author with whose writings I am acquainted. Pope, in his Essay on Man, says: "See through this air, this ocean and this earth, All matter quick, and bursting into birth, Above, how high progressive life may go! Around, how wide! how deep extend below! Vast chain of being! which from God began, Nature's ethereal, human, angel, man, Beast. bird, fish, insect! what no eye can see, No glass can reach; from infinite to thee, From thee to nothing." Properties of caloric. In seems to me no assumption, nor presumption, to say, that there is such an element of matter as caloric, or fire, that it is a subtile fluid, and one of the best and longest known of all the elements of the mnaterial world. It is the great solvent of nature; and the fact that it enters into all solids, all fluids, and all gases, and expands them, proves very conclusively its material nature. Caloric and electricity permeate all bodies, whetnher porous or solid. They permeate solid iron as much and readily as they do porous wood, brick, and stone; all of which are equally expanded by them.;Water permeates porous wood, brick, and stone, and all other porous substances, and expands wood and most other things; but it never penetrates solid iron, nor metals of any kind, and therefore cannot expand them. Hence the conclusion is forced upon us, that though ACTION OF CALORIC. I7 caloric is more subtile than water, it is equally material. It passes through bodies slowly, like a fluid. Caloric has affinities for other elements of matter -for some much stronger than for others-for elements and articles called poor conductors, much greater than for those called good conductors. Greater for compound substances than for simple elements of matter. Greater for the aqueous vapor in the atmosphere, than for the oxygen and nitrogen of which the atmosphere is mostly composed. Greater for inanimate vegetable products, than for the metals or the earths-but much greater for living organisms, either animal or vegetable, than it has for inanimate matter. Though caloric is drawn from the earth into the atmosphere by solar attraction, yet nearly all solids and liquids within the direct influence of the sun's attraction, become warmer than the atmosphere which surrounds them; and the higher we ascend into the atmosphere, the less heat we find, until we come to the region of constant frost and snow, upon elevated mountains, even in the torrid zone. These facts show that caloric has greater affinities for, and is more strongly attracted by solids and fluids, than by atmospheric air, and that it has less affinity for the rarified air upon mountains, than for the more dense air in lower situations, and on the sea. The indications are that caloric never exists, otherwise than in connection with other matter-that it never exists in the regions of space that are destitute of grosser matter. This is indicated by the fact, that caloric can not be obtained separate ftom other matter, and bottled up, or confined in glass jars, as electrici ty and all the grosser elemrIents of matter can. Caloric permeates everything, but combines chemically with nothing-though the union of caloric with the vital element, and also with electricity, must be analagous to chemical combinations. Caloric seems to have a strong affinity for combinations or compounds of the elements of nature; but not for the elements themselves —except the vital ele2 I8 ACTION OF CALORIC. ment and electricity. It seems to have something analogous to chemical affinity for the vital element, and also for electricity; with each of which it combines, and forms a union and combination analogous to chemical combinations. It never forms anything like a chemical combination with any of the ponderable elements of matter; and yet it has so strong an affinity for the chemical compounds and nmixtures of ponderable matter, that it adheres to them with great tenacity-permeating the interstices between the atoms, separating them, and expanding the compound, and tending to an equilibrium-to equalize itself in all parts of the compound. My theory and mode of reasoning lead me to the conclusion, that not a particle of caloric, ntor any combination of it, exists in the universe, except in combination or contact with other matter. The use of the spectroscope has shown, as clearly as is practicable with the scientific instruments now in use, that the sun and its atmosphere is not constituted of the elements of heat and light alone, but of all the metals and elements of this earth, in a liquid or gaseous state. Limited tendency of caloric to diffusion. Caloric has no cohesive power. Being destitute of the attractive power of cohesion, some have supposed that it has a self-repelling power; but such is not the case. The mistaken idea has arisen from the fact that cold substances attract caloric more strongly than heated ones do-and hence its tendency to escape from the latter to the former-to diffuse itself to a limited extent, by what is termed radiation-to flow from hot stoves, furnaces, seats of combustion, and other places and articles in which it is accumulated and in excess, into the surrounding atmosphere, and into all bodies in the vicinity, which are not so hot as the place from whence it is radiated. Hence some have supposed that it has a natural tendency to diffusionto diffuse itself through the universe, and to seek what ACTION OF CALORIC. I9 is termed an equilibrium, or equality of heat, in all parts of the universe. But such is not the case. The fact that the sun contains a thousand times as much caloric as all the rest of our solar system, is of itself evidence that its tendency to concentration and accumulation in other matter, is much stronger than its tendency to diffusion; and the fact that even in the torrid zone there is constant snow and ice upon the mountains, less than twenty thousand feet above the level of the sea, indicates that caloric never exists except in connection with other matter, and that it is not diflused through the realms of space. Ignition and combustion-flame and fusion. Webster defines ignition,-" as I, the act of kindling, or setting on fire; 2, the act or operation of communicating fire or heat, till the substance becomes red or luminous; 3, the state of bVeing kindled; or heated to redness or lumi)lousness." Wood, when in a coftfined place, where there is no atmospheric air, or very little if any, may be gradually permeated and saturated with caloric, until it is browned and partially charred, and its texture and strength nearly destroyed-before it becomes red, and ignition and combustion commence; and it may burn for hours and days, and gradually consume away without flame, if it be covered up by ashes or earth, or otherwise kept from circulating air. The origin of fires in beams, ioist, floors, and partitions of buildings, near flues of cfhimnies by which they are warmed, shows in many cases, that caloric has passed through four inches or more of brick or stone and mortar, before it reached the wood, which it permeated and gradually saturated and heattcd, for hours, and perhaps (lays, and in some instances weeks, in succession-before the accumulation of the caloric in the wood was so great as to produce ignition and combustion-which often goes on for hours and days before it burns through to a place where it receives a current of air 20 ACTION OF CALORIC. when a blaze or flame is produced by the air coming in contact with the burning fire. While a current of air is necessary to produce rapid combustion and flame, very little if any is necessary to produce a slow smothered combustion, without flame. Iron may be so heated and saturated with caloric, as to become scarlet red and then white, and will instantly give off caloric and ignite combustible materials which touch it-without itself burning. Iron and most other metals never burn in common atmospheric air, until after they have been melted, reduced to a fluid state, and the intensity of the heat increased, until they are converted into vapor. Woolen cloths mav be so heated and saturated with caloric, as to have their texture and strength destroyed, before ignition and combustion take place; and leather, india rubber goods, and many other things, may be partially melted without ignition. In fact animal products with the exception of their fats and oils, produce very little name in burning. Many chemists and physicists treat combustion as a chemical process, caused, commenced, and maintained, by chemical affinities, and chemical action; but my reasoning being in a different channel-based upon caloric as an elementary substance, and an active agent, it leads to very different conclusions. Some who have not fallen into the vibratory-ether theory of heat, have had their reasoning tinctured and warped. by its false doctrines. Prof. Porter, of Yale College, in his Principles of Chemistry, says: " Combustion may be defined as a combination of any two substances, attended by light and heat. Metals which will not burn in the air, because it is diluted oxygen, burn brilliantly in pure oxygen." Johnston in his Manual of Chemistry, says: " Ordinary combustion consists in the union of combustible mattelwith oxygen, and is usually attended by the evolution of heat and light." Ganot says: "Combustion is chemical combination, attended with the evolution of light and heat." ACTION OF CALORIC. 21 My understanding of combustion is, that its commence nent is an entirely calorific process —that neither oxygen nor chemical action has any agency in the process, until after caloric has permeated and decamposed the wood, coal, or oil, and separated their constituent elements-when, if oxygen be present, it attracts the carhon and combines with it; and if there be a current of air, it aids in carrying off the new compounds-and thus renders the combustion more active and rapid. I therefore regard ig nition and tlhe comnmezcemnent Of combustion, as a phurely calorjftc process, and the maintenance of active and rapid combustion, as a compound process-mostly calorific, but promoted by the co-operative agency of oxygen, and chemical action. The conversion of water into steam and vapor, and the melting of iron and other metals, and their conversion into a liquid form, is a purely calorific process-in which the chemical affinities and chemical action have no agency whatever. The great fire in Chicago, in October, I87I, SO melted the surface of iron, and of stone, glass, and earthenware, as to fuse them, and run them into conglomerates; and the great fire in Boston, partially melted and destroyed the largest granite columns, and the most massive granite walls. Such wonderful effects were produced by a process purely calorific. So far from ignition and combustion being a chemical process, dependent upon chemical action -chemical action is in many cases dependent upon caloric, as a necessary stimulant-to excite it, and carry it on. Caloric is a necessary stimulant to aid in exciting chemical action —whereby the combination of many substances is formed, which can not be formed without it. Porter says: " Simple contact of a metalloid and o —ygen, is not generally sufficient to produce an acid. Heat is one among the additional means employed." Again, he says: " Heat is often essential to chemical combination. This is almost always the case where both 22 ACTION OF CALORIC. substances are a solid. Besides heightening their chemical affinity, heat has the effect of bringing the'particles into closer and more general contact, and within the range of affinity, by the melting or fusion which it accomplishes. Sulphur and iron, for example, require the aid of heat to bring about their union. The sulphur melts, and then combines with the iron." Chemists and Physicists have been inclined to attribute too much influence and power to chemical affinity and chemical action —and quite too little to caloric, and thermal or calorific action. Physicians are the only class, who have attached due i mportance and influence to heat and thermal action. " Curious conseqnences of heat. "The following, on the effect of intense heat upon different substances in the great fire in Boston, comes from Rev. Christopher Cushing, D. D.: " A brick vault was built up from solid foundations, and stood like a tower amid the ruins. The walls of the vault were about 20 inches thick, with an air-chamber on all sides of four inches space. Inside of this vault there was a heavy steel safe. The interior of the vault, that is, the space not occupied by the safe, was filled with rolls of broadcloths, placed there during the raging of the fire, for safety.' The wooden lining of the vault was so charred, that when water was poured upon it, it crumbled to atoms. The rolls of cloth were partially consumed, and entirely ruined. A tin box back of the cloths, which contained the manuscript reports of the Commissioners of the Charity Fund of Amherst College, was so heated as to melt off the lock on the inside, and yet the-papers in it were preserved. "' Inside of the steel safe there was a wooden trunk, covered with leather, and wrapped in several thicknesses of paper, sealed with common sealing-wax. The wrapping paper was in good condition and the sealing-wax also, but the leather covering of the trunk inside of the pafier, was melted. The wood of the trunk showed no marks of fire, but a leather ortfolio inside of it was reduced to a crisp. In this portfolio there were numerous compartments, each bound with leather, a quarter of an inch wide; this leather bindtng was so melted as to seal all the compartments. When these were separated with a knife, the cloth lining of the compartments was found unaffected by the fire, and the papers enclosed were in good condition.' ACTION OF CALORIC. 23 "From this case, leather proves among the poorest of materials in case of fire, even poorer than sealing-wax; and where there is intense heat without ignition, paper is among the best." PFi7es from steam pt'ies. The possible, or probable, danger of fires from steam pipes, is attracting considerable attention in connection with the gen -ral subject of the causes of combustion, and the belief is held by many that wood work near such pipes, is very often insuffciently protected, by reason of the prevalent idea tPiat hot water pipes will not cause wood to takefire. On this point a report made by a committee of the Franklin Institute, at Philadelphia, will be of interest. This report was made in x856, and was on a case of apparently spontaneous tgnition of sawdust occurring in the factory of Joseph S. E'kinton & Son. " Mr. Elkinton states that he observed a mass of sawdust, which had been confined for about nine months by a wooden box around one of Wilson's patent tanks for rendering grease, heated to a red heat like a mass of live coal, apparently ready to burst into dames, although at a distance of forty feet from any fire "' The tank is a cylindrical vessel of boiler iron, about ten feet high, and four feet in diameter; it is made steam tight, having openings which can be closed at pleasure near the top and bottom, for the admission and discharge of fatty matters to be melted. Heat is applied by introducing steam through a pipe opening into the bottom of the tank; the pressure used is about fifty pounds to the square inch (equal to 280 degrees Fah). The heat is applied from six to nine hours in succession, and the apparatus used two or three times a week. "When he fire was first dz:scovered, an inch boardforming lpart of the bottom of the box, had been burned through. The fire appears to have begun near the bottom ot the box, but in several other places cwhere the sawdust touched the sides of the tank, it was charred. Mr. Elkinton attributes the entire destruction of his father's factory in I853, to a similar accident. " Day & Martin's Blacking Factory, in I-igh Holborn, was heated by hot water circulating in tubes, the temperature never much exceeding 300 degrees Fah. Ir. December, 1848, the wooden cas'ng and other wood work about the uipright p ipes, were found to be on firA and on examination it was found that wherever the pipes touched the fioor,the boards were charred. " It is also a fact, distinctly pointed out by Mr. Braid 24 ACTION OF CALORIC. wood, Chief of the London Fire Brigade, that wood long e x 2Posed to tentheratnres but little above that of boiling water, will become, after a time, charred, and will actually inflame. Numerous instances of accidental fires thus.caused, have been adduced. " The fact is established, that such combustion will occur under the circumstances indicated, and is of importance, from the liability to recurrence of the accident under like circumstances-as in cases of joist running near flues or through hot-air chambers; wood work on steamboats near the boiler, steam drum, or smoke-stack; jacketing of boilers, in ordinary situations, etc." Upon the calorific theory of heat, ignition, and combustion, it is easy to account for fires originating from steam pipes and hot flues of chimneys; but how can they be accounted for upon the vibratory-ether theory of heat? Tihe other elements of matter, their properties and affinities, being treated ot by chemists, without many great differences of opinion, ldo not come within the scope and object of this woik. CHAPTER III. THE FORCES OF NATURE, THEY ARE INHERENT IN SUBSTANCE-POWER AND MOTION-CAUSE AND EFFECT-MATTER AND MOTION-LAW AND GOVERNMENT. Ahe forces of nature; inherent in substance. Tile forces of nature consist of the chemical affinities of the elements of matter, of the attraction'of cohesion, of the universal attraction for each other, of all the elements and bodies in the universe-which is called gravitation-and the peculiar affinities of such elements as caloric, electricity, and the vital principle. These forces constitute the causes of action, and the powers which produce all the motion and change in the universe-except what is produced by mind, and by the immediate agency of the Deity. Caloric and electricity are the most mobile and active of all the elements, and their peculiar affinities, and that of the vital principle, constitute the most powerful and efficient forces in nature. The words force and cause are often used in a vague and mystical sense, without any definite meaning. It is impossible for me to conceive the existence of force, power, or cause of action of any kind, except as an inherent property or attribute of matter, or substance. We can not have any clear conception of even a Supreme Being, as existing without substance. It is to my mind an absurdity to suppose, that force or power, spirit or intellect, or entities of any kind, can exist without, and independent of substance —or in 26 THE FORCES OF NATURE. any mode other than as a property, quality, or active attribute of substance. The principal distinction between matter and spirit or intellect is, that the latter is not controlled in its action by, nor subject to, the affinities, forces, and powers, which govern the material world. The active properties of matter are not perceptible to the senses. Tile chemical affinities and the property of gravitation are matters of inference only -mere deductions of human reason, from the phenomlena of the material world, and the effects produced by different elements acting upon each other. Though not visible to the eye, the chemical affinities and other active properties of matter, are none the less real. They are as latent and hidden friomr the senses as the vital principle or the intellect, and yet no educated intelligent person can doubt their realityand there is just as little reason to doubt the existence of either the vital principle or the intellect. Power and motion-cause and efect. Power and motion are nearly synonymous with cause and effect. Motion can not be produced with-' out a power being exerted to produce it; which power is tile cause of the motion. Nor can there be motion without matter or substance, which is moved -the motion being the first effect, and the change in the matter or thing moved, the second, antd generally more permanent effect produced by the action of the power or cause. The change referred to must be a change of some atom or atoms, or coinbinatioai of atoms of mattei. Effect or change presupposes power, acting as a force or cause, which produced motion and the change. A cause must be a power or force, inherent in substance. We can have no conception of force, power, or action, without and independent of substance. Force and power to act must be inherent properties or attributes of substance. All causes nmust THE FORCES OF NATURE. 27 be persons or things, havingl inherent forces and powers, capable of action-and which have acted, and l)roduced effects; and all effects must be the results of action, and the changes produced by it. Action is the first and immediate effect of a cause; and though it is the antecedent of every effect immediately foilowing it, yet, strictly speaking, it is never the cause of such eflect. Some have supposed that cause was simply an antecedent fact or action, state or condition,-forminmg a link in the great chain of natural events and developments succeeeding each other-each of which has been, in soine way, tile cause of its successor. But that mode of reasoning overlooks thle action of the forces of nature, which are the real causes that produce the succession of events that we witness in the universe,-and supposes that one event in somne mysterious mode, produces the one which succeeds it. Such reasoning is fallacious. A cause is something more than a mere antecedent-it is an active force, capable of producing by action, motion and change in the things upon which it operates. AJlalter and mtotion. The atomns of matter of which the universe is composed, have an existence in some measure independent. They never cease to exist. The properties of matter are the qualities and forces inherent in the atoms, and are as real and unchangable as the atoms themselves-though they have no independent existence. On the contrary, motion is a mere condition of matter when not at rest-but -noving. Hence nmotion ceases, and has no existence when tile matter, of which it is a condition, ceases to move, and is at rest. Matter is necessarily permanent and continuous, and never ceases to exist. Motion is not necessarily permanent, nor continuous, but often ceases. The atmosphere, or the atoms of which it is composed, have a permanent existence; but its motion is wonderfully 28 THE FORCES OF NATURE. irregular, and often ceases entirely, or nearly so, in large districts of country. The surface of the sea is moved rapidly by winds as well as by tides,-but with great irregularity-while the great body of water in the ocean is generally nearly at rest. Atoms of matter may be concentrated and accumulated. Atoms of caloric may be concentrated and accumulated by combustion, until a wonderful intensity of heat is produced-capable of melting and reducing to vapor, iron and other metals; but it is impossible to accutnulate motion in like manner-because it is a mere condition of matter, and there is no room for the atoms of matter, of which it is a condition, to move and keep in rapid inotion when concentrated and accumulated. As mobile as caloric and electricity are, they are at rest when accumulated in considerable quantities; and yet they do not lose their qualities and forces by being at rest; but when motion ceases, all its qualities and forces cease with it. Hence motion can not produce much heat, nor be a constant and permanent source of it. Repellenl fvrces-are there any? Some of the language used by authors on science indicates that there are repellent, or repulsive, as well as attractive forces in nature; but this may well be doubted. My belief is that what are called repulsive forces are apparent only, and not real. Some authors have treated caloric or hieat, as a repelling force; but I do not so regard it. They treat the expansion of solids, liquids, and gases, by caloric or heat, as evidence of a repelling force existing in it-but I view it in a different light. Caloric could never enter into solids if it had not a strong affinity for them-a much stronger affinity for iron (for instance) when cooler than the fire or atmosphere surrounding it, than the atoms of iron have for each other-so that the affinity or force by which the iron attracts caloric, is stronger than the cohesive attraction TIlE FORCES OF NATURE. 29 )f the atoms of iron for each other-whereby caloric.s drawn into the iron, and by means of the space Dccupied by the atoms of caloric, and their power of resistance, they force asunder, to a very small extent, the atoms of iron between which they enter. The force, by the action of which caloric enters iron, is the force of attraction, and not a repelling force; and the atoms of iron are forced asunder by the properties of caloric which are common to every element matter. Every other apparent repulsion of one element or compound of matter by another, may be accounted for in a similar manner. The repulsion is apparent only-and is produced by some stronger attraction in a different direction. The wonderful activity of caloric and its tendency to permeate and expand all solids, liquids, and gases, must arise from its strong affinity for every element of matter in the universe-affinities which must be much stronger than any of the chemical affinities of different elements of matter for eaci other-stronger also than the'attraction of cohesion between the atoms of any of the metals-and much stronger- for cold than for heated substances. Rcadiation of caloric. What is called radiation of caloric or heat from an open fire, stove, or furnace, is caused by the atraction of caloric by the substances and atmosphere surrounding the fire or stove-whereby it is attracted and drawn by the former from the latter-by the colder or cooler from the fire or heated things. The caloric is not driven out of the fire or heated stove by a repelling energy, but drawn out by an attractive force, or affinity. The sun is the great attracting power in our solar system. It constantly attracts all the elements of matter in the universe. It attracts,.moves, and keeps in their orbits, the earth and all the planets. It attracts 30 THE FORCES OF NATURE. and draws caloric from the crust of the earth during the day, which is absorbed again by the earth at night. Is it possible for the sun to act as an attracting andrepeling force also, to attract caloric, electricity, and all other elements of matter-and at the same timne radiate and repel from it caloric, or any other element of matter? Does not sucli supposed action involve a contradiction?-and is it not therefore impossible? a-aw-what is ti-and wAt are its functions and lini/s? We often hear it sail that every thing is governed by law-that our system of worlds, and the whole universe, is governed by law. The Duke of Argyle has written a volume entitled the reign of law. All such expressions are metaphorical and have no definite meaning. They imply that law has a governing power —that the physical laws of nature have an inherent force and power, by which they are executed. But such is not the case. Law is not a force -not a power-not a cause of action-but simply a mode or rule of action. The laws of a country do not execute themselves; they are mere rules of action and of property-nmere modes and customs, usages and rules, in accordance with which business is transacted-rights actquired, determilned, and adjustedwrongs remedied-and crimes and oflenses punished. They require administrative, executive, and police powers to execute them, and judicial officers to interpret and apply them. What are called the physical laws of nature are simply the modes of action of the inherent properties and forces of different elements ncf matter-acting upon each other. Thley are not the forces themselves-not the powers which produce action-not the causes of action. On the contrary, they assume more the character of results than forces or causes. All motion and change in the material universe. not caused directly b~y THE FORCES OF NATURE. 31 spirit, is effected by the properties and forces inherent in the elements of matter-and not by law; and when it is said that the universe is governed by law, the word law is used in a metaphorical sense-meaning the properties and forces inherent inl the elements of matter, acting upon each other. The properties and forces inherent in the elements of the material world, act with uniformity-always the same; and hence what we call the laws of nature, (speaking metaphorically), meaning the action of the forces of nature, act with perfect uniformity fiom age to age. The action is uniform and invariable, because it is produced and determined by the properties of matter, and the forces inherent in the material world -which are and must always remain the same-unless changed by the Supreme Being-whose supreme power, as Creator and (Governor of the universe, places him above nature; and his action,s therefore called super-natural. The laws of nature may be divided into two classes —physical and moral. The physical laws of nature are the modes in which the forces of nature act; or in common parlance, they are the forces of nature. The moral laws of nature are rules of action for nan, to be dedluc.ed fiomn his constitution and nature, and from the nature of things; and they should be framed accordingly as rules of action, fir his guidance; they shoulcd be adapted to his constitution and nature, condition and circurmlstonces; and when so frinied and followed, their natural tendency is to promote his welare. The principle of life-the organizing element of animal and vegetable life, firms an element of the material world, an(l is governed by its own inherent properties and forces, tendencies and affinities-like other elements of matter. It acts blindly and uniformly, without intelligence-thoutgh it forms the connecting link between ponderable inanimate matter and spirit, or intelligent substance; and its action is the same as if guided directly by intelligence. But the 32 THE FORCES OF NATURE. most of the action of the animal economy is determined by the natural tendencies and forces of unintelligent matter, and not by intellect; for the mind of man can take no direct cognizance of the action of the animal economy within him, and has no knowledge of it, except the inferences of reason. There is the same manifestation of apparent intelligence, and of action in accordance with a purpose, in the germination, development, and growth of plants and trees, as in animals and man; but it requires a great siretch of the imagination to suppose that plants and trees are endowed with intellect, knowledge of their situation and wants, and of the proper modes of supplying them!)y forming sap, and forcing and directing it into the proper organs, and parts of the organism-nto nourish them. It is more conceivable that the vital principle acts like other elements of nature, in accordance with its inherent properties, tendencies, and forces, withiout intell.gence; and that its affinities and forces tend to produce, develop, and sustain animll and vegetable organisms-in accordance with the types of the germs of the organisms, from which they are developed. The living prinlciple-like all the other elements of nature, acts firom necessity-in accordance with its inherent properties, forces, and tendencies; but the wonderful organismrs which it forms, and their various powers and uses, all indicate that its forces, the plan and purposes of its action, and all the higher types of organisms, were devised by Divine agency. As the forces of natare spring from the inherent properties and affinities of the elements of matter, they act from necessity; and therefore they act with uniformity. In common parlance, their action is governed by law-the term law, as generally used, being synon imous with the forces of nature. Some have gone so far as to affirm that not only the material world and the mind of man, but that God also is governed by law. Such are the results of the doctrines of necessitarianism; but they lead directly to THE FORCES OF NATURE. 33 fatalism and pantheism-and are totally inconsistent with the idea of a Creator-acting as an intelligent and free moral agent. God must be supra-nature and above law; that is above the forces of nature, Wvith power to act upon and control them-th lugh they have no power to act upon him; otherwise he must be destitute of creative power. The intellect of man being blended with the vital principle and with ponderable elements of nature, the forces of nature act upon the mind, through the nervous system and brain, as its organs; an I so tar as its action is directed by such influences and agencies, it is governed by law-that is by the forces of nature; but so far A.s it originates action and acts of itself, whlen the senses are at rest and do not act upon it, it acts independently, and without law. It then acts within a limited sphere, as a cause-as a centre and source of action and of power, and is directed by its own wrill and intelligence. Its action is then assimilated, in some respects, to that of the Deity. As the mind is more or less influenced by its own intelligence and ideas, theories and opinions, rmaxiims and dogmas, rules of action and purposes of life-all of which are more or less defective and erroneous, its reasoning must necessarily be more or less tainted with error. Hence mental action is not uniform, as is the action of the forces of nature; and hence all human reasoning is uncertain-except what relates to mathematical subjecti. No two persons reason alike, tipon all subjects and questions. The human intellect as well as the Divine Mind, belongs to the domain of the supernatural, and is not subject to law, so far as it acts from its own inherent powers and intelligence. Hence I come to the conclusion that the domain of law has limits; that it does not extend to the Divine Mind; and that it only parti3 34 THE FORCES OF NATURE. ally, and indirectly, directs and governs the human mind. Alexander Pope, in his universal prayer, says: " Yet gave me, in this dark estate, To see the good from ill; And binding nature fast in fate, Left free the human will." CHAPTER IV. MYSTERIES-AND THE BASIS AND LIMITS OF HUMAN KNOWLtVLDGE. Man finds in existence the earth upon which he lives, and also innumerable bodies floating in the realms of space, moving in their respective spheres-forming systems of worlds-each and all composed of various atoms and elements of matter, which have inherent properties and forces that tend to produce action. Hulman reason suggests to the mind various queries in relation to the origin, creation, changes in, and government of the vast systems of worlds, which form the universe. To suppose them to have been eternal and self-existent -without any beginning, seems like an absurdity. To.suppose them to have come into existence either gradually or otherwise, without a Creator or Supreme Cause, seems still more absurd. And, to suppose them to have been called into existence from nonentity or created out of nothing, seems to. the human mind like all impassibility-for we can have no clear and distinct conceptions of the powers and modes of action of the Deity. Each of the modes suggested presents a dilemma to our limited understandings. The whole subject of creation-of the origin and government of the universe, is veiled in mystery. It is beyond man's knowledge and comprehension-beyond the reach of scientific investigation-and beyond the sphere of what is called science. Every theory and hypothesis which we can form upon the subject, is unsatisfactory; and yet the great fact of the existence of these systems of worlds forces itself upon the attention, and commands the assent of the mind. 36 MYSTERIES IN NATURE. The creation and the origin of things lying beyond the domain of man's knowledge, faculties, and comprehension, he should take things as he finds them; acknowledge his incapacity to determine their origin and causes; and contefnt himself with their action and phenomena, and with analyzing and studying their nature and properties, forces and tendencies, which come within the reach of his faculties. Though the facts of geology and of natural history give him much valuable information of the changes which the earth's crust has undergone, they cannot teach him, and he can never know, the origin of matter and of the universe. The scriptures do not attempt to teach the modes and methods of creation; but declare only the the general fact, that'" God made the heavens and the earth, and all that in them is." Nor do mysteries cease with the creation-with the existence of our solar system, and the vast systems of worlds forming the universe in full operation-nor even with the admitted existence of a Supreme Being,in addition thereto. But with such a standpoint admitted as true, as the foundation of our reasoning, we get within the sphere and domain of investigation and human science, and can then overcome many of the minor difficulties and mysteries which beset our path —can partially overcome many others, and can arrive at certainty in many things, and at reasonable probabilities in many others. Chemistry has been prosecuted with such intelligence, energy and success, by great numbers of persons, during the last two hundred years, that we have reason to believe nearly all compound bodies have been decomposed and analyzed, and the elementary substances of nature ascertained, with a close approximation to accuracy; and yet we know nothing of the ultimate atoms and properties of matter, except the inferences of human reason. So numerous have been the experiments of chemistry by different persons, with such uniform results in most particulars, that there are very few differences of opinion among chem MYSTERIES IN NATURE. 37 ists and scientists at the present day,lin relation to any of the elements, properties, and forces that exist in the universe, except heat or caloric and light, electricity and magnetism, the vital element, and the princziple of intelligence. But in relation to these six elements and principles, and their respective forces, powers and modes of action, scientists are as much divided in opinion at the present day, as they ever were. Though scientific investigations and experiments have settled many questions, they have, in some cases, led only to new controversies. Though electricity has been studied and experimented witli, for more thon a century, by numerous persons, with great diligence -and success, and has been made by the invention of man, a most wonderful agent for the transmission of intelligence —yet dwe know nothing of its ultimate atoms and nature, very little of its connection with, and how it cooperates in action, with caloric on the one hand, and magnetism on the other; and its mode of action, in transmitting influences thousands of miles in a second, is a profound mvstery. Of magnetism still less is known than of electricity-and the whole subject of it is involved in in mystery. Though caloric-the cause of combustion and heat, is the best known to the common mind of all the elemnents and forces of nature, yet the reasoning of some distinguished men, has recently involved the whole subject in mysticism and sophistry. Some of the action of caloric, and the influence of the sun in warming the atmosphere and the surface of the earth, are truly mysterious. The sources of caloric, and the influences of the sun upon its action, are discussed in the next chapter. Of the essence, nature, and mode of action of what is called light, nothing is, or can be known with certainty. All our knowledge upon the subject consists of the inferences of human reason, and depends upon our limited faculties, the imperfections of the huiman understanding, and the uncertainties of all humhan 38 MYSTERIES IN NATURE. reasoning. Scientific experiments have thrown much light upon the action of both heat and light, but they leave the causes of such action still involved in mystery. There has been mulch dogmatism upon the subject of both heat and light-based upon mere assuImption, without any solid foundation. The subject is treated of more at length in Chapter VI. The vital princifple, and the whole subject of the origin and development of life, is involved in controversy, as well as in mystery. All our knowledge upon the subject arises from the inferences, and depends upon tlie imperfections of human reason. The subject has been mystified, by being associated with materialism, which must be examined in connection with it. There are several classes or schools of materialists; one of which can scarcely be distinguished from Pantheists-though Pantheism is not consistent with the existence of a personal Deity. Another school of materialists recognize a vital principle, or element in nature, which is the active agent that attracts, unites, combines, and holds in (ombination certain elements of matter, and forms them into vegetable and animal organisms-and by a process called spontaneous generation, produced plants and animals upon the earth, when it was fitted for tlhem. A third school of materialists ignore not only the the intellectual principle, but also the vital principle, and the doctrines of vitalismi; and have adopted what has been aptly termed the mechanical theory of 1ife, and of the formations of living organisms —holding that all "matter has a tendency to orgazize itsef —to grow into shape-to assume definite forms in obedience to the definite action of an (tll-pervadingforce" -that"the lormation of a crystal, a plant, or an animal, is a purely mechanical problem "*-produced *See Prof. Tyndall's lecture on Scientific Materialism, in his Fragments of Science. MYSTERIES IN NATURE. 39 by the same forces, or by forces of the same characte"r; and that there is no vital organizing principle which forms plants and animal organizations, that does not apply to crystals, and chemical combinations. This school also believe, not only in the development theory, and the theory of the spontaneous generation of both plants and animals, but they believe that all such results are produced by the action of the forces of inanimate matter-without the agency of a vital element endowed with organizing powers, which distinguish it from other elements of matter. The theory of a vital organizing element, and many of the doctrines deduced from it, is not by any means inconsistent with the existence of a Divine Creator and Governor of the universe-for, if secondary causes are recognized at all, as agencies established by the Deity to effect his purposes, no more appropriate agency, than that of a vital organizing principle can be imnagined. But, for fear of recognizing a principle which might in the view of some minds, give support to one of the schools of materialism, many intelligent religious men unwittingly join with the mechanical school of materialists, in denying the existence of a vital organizing element. To suppose that God has endowed matter witl active properties and forces, as secondary causes and agencies, with which to-operate the universe and produce the phenomena thereof, does not, in the least degree, derogate from the supremacy of his power. To deny the existence of secondary causes, and affirm that all the action in the material world is caused by the immediate agency of God, is equivalent to affirming that matter has no active properties-that there are no forces in nature otlier than the power of God-moving atoms and comprounds as well as worlds of matterand that what we call chemical affinities, attraction of cohesion, gravitation,and magnetic influences, and the apparently active forces of caloric and electricity, are all only manifestations of the direct acts of God. To assume such positions is to reduce the Deity to a mere 40 MYSTERIES IN NATURE. mechanical or natural agency, and to get down to Pantheism-pure and simple. It seems to me impossible to ignore the vital principle. without falling into materialism in some form-of either the Pantheistic or the mechanical school. If persons seek to avoid Pantheism by recognizing secondary causes, and still deny the existence of a vital element, they must supply its place by attributing to other elements of nature the same organizing forces and tendencies, which the vitalists attribute to a vital element-and thus they fall into substantially the same views as the materialists of the mechanical school-for the same course of reasoning which disposes of and ignores a vital element, will also dispose of an intellectual principle, and make mind, as well as life, the mere result of organization. The theory of a vital organizing element, carried out to its legitimate consequences, many think leads to spontaneous generation; but whether it does so or not, it is necessary to the development of living organisms from seeds and germs, or by means of sexual generation, and to their subsequent support and growthunless other elements of nature supply its place-in accordance with the mechanical theory of life. But the theory of spontaneous generation of plants and the lower grades of animals, is by no means inconsistent with the idea that God established the types of the higher grades of animals and of man, and gave them intellects appropriate to their respective types, and spheres of action. The subje(ct of the vital element is discussed more at length in Chapter VIII. The origin of man's intellect is equally mysterious and incomprehensible, as that of the universe, and the manner, in which the intellect is blended with the physical organization of the brain, is also mysterious, and beyond the reach of our investigations and limited conceptions; but the great fact of the existence of the intellect with various capacities, is attested by the consciousness of every individual. It is attested by the same evidence which attests the existence of the mate MYSTERIES IN NATURE. 41 rial world. The physical senses-the sight, the hearing, and the feeling or touch, would communicate no knowledge to the brain without the intellect. Without the intellect, the senses would convey impressions only-like caloric and electricity, in the material world -which would affect vitality and growth, but could produce no perceptions and no knowledge-no consciousness and no ideas. Chemical combinations often neutralize some of the properties of their elements; but never produce properties or forces not possessed by any of their elements when in a separate state. To me it seems like an absurdity, to suppose that the combination and organization in any form, of several elements of unintelizgent matter, can produce intellect and intelligence -which would be the production of a force, faculty, or property, not possessed by the several elements in a separate state. It seems irrational to suppose that the human mind can be the tIiere result of tile combination of uninteiizgent matter. Consciousness and intelligence never can result, as it seems to me, from the unintelligent forces of nature. Consciousness and perceptions, ideas and knowledge, can be caused by impressions made upon an intelligent principle, or spiritual entity; but not by those made upon unintelligent matter. Plants have organization, but, for want of intellect, have no perceptions, no consciousness, and no knowledge of the impressions made upon them. Forces af affinity and attraction. The mode of action of the principle or force of affinity anti attraction, is also mysterious. It is less difficult however to conceive the mode of action of the attraction of cohesion and the chemical affinities of atoms of matter which are in contact, or very near to each other, than it is to conceive how the celestial bodies can attract each other at the distance of millions of miles. How physical forces can operate at 42 MYSTERIES IN NATURE. such immense distances, is wonderfully mysterious, and beyond the comprehension of man; and yet the movement of the planets, comets, and other celestial bodies in their respective orbits, leave no room to doubt that they are all moved by the force of attraction-ex erting its influence at vast distances. Whenl the theory of attraction and gravitation as governing forces was first suggested, it was difficulc for the human mind to conceive how it was possible for celestial bodies to operate upon and attract each other at the distance of hundreds of millions of miles; and when the doctrine of gravitation was first presented, and it was taught that the sun as the centrc and great orb of our solar system, governed the whole, and by the power of attraction kept the planets in motion and in their respective paths, at distances varying from thirty-six millions to several hundred millions of miles -the human mind very generally revolted from the idea as. an impossibility, and an absurdity; but after such men as Kepler, Newton, and LaPlace had revolved the subject in their minds for years, and found that upon the theory of gravitation and the universal attraction of the heavenly bodies towards each other, the phenomena of the solar system could be understood and explained, and that they could be accounted for in no other manner, the theory was generally admitted to be true —lowever great the mystery. CHAPTER V. SOURCES OF CALORIC, OR FIRE, AND THE INFLUENCE OF THE SUN UPON ITS ACTION. Ganot says in his Physics, that our globe possesses a heat peculiar to it, which is called terrestrial heat; and that the variations of temperature which occur at the surface gradually penetrate to a certain depth, at which their influence becomes too slight to be sensible. Hence, he says it is ccncludled, that the solar hieat does not penetrate below a certain internal layer, which is called the layer of constant or uniform temperature (the same in winter as in sumlner;) which depth below the earth's surface varies of course in different latitudes and paits of the globe; but at Paris it is about thirty yards below the surface, where the temperature is constant at about II degrees Centigrade; that below the layer of constant temperature, the heat is observed to increase on an average I~ Centigrade for every 90 feet; and that this increase has been (,bserved in mines and artesian wells. Now let us suppose that in the temperate zones the point of uniform temperature be generally reached at a depth of Ioo feet below the surface of the earth, that it is there Io~ Centigrade (equal to 50 Fahrenlheit) and that the increase is equal to I~ Centigrade for IOO feet in depth-the point where water would boil would be reached at 9.Ioo feet, or less than two miles below the surface-tin would melt at a depth of 22,ooo ficet-silver at less than Ioo,ooo feet-anad iron at I49,000 feet, or less than 30 miles b(,low the surface of the earth. This is probably as near an approximation to the truth as it is possible to attain. Hence we may 44 SOURCES OF CALORIC. reasonably infer, that the crust of the earth at the equator is only about 25 or 30 miles thick, and not over 40 or 50 miles thick at the poles. Though it is generally admitted that the interior of the earth is an igneous mass of melted metals and earths, yet the commonly received opinion is, that all the heat at its surface and in the atmosphere, is emitted and radiated from the sun, as the great source of heat and light, from which the whole solar system is supplied-and that heat and light are constantly emitted from the sun, and radiated from it into space, in every direction. If such were the case-if all the heat at the surface of the earth and in the atmosphere came directly from the sun, as appearances at first view indicate, the heat of the atmosphere and ot the ground and rocks would be as great upon the tops,of lofty mountains as it is at the level of the sea-when we know that there is perpetual snow and ice, even in the torrid zone, at elevations less than twenty thousand feet above the sea. This well known fact is totally inconsistent with the received opinion, that the caloric or heat which warms the atmosphere and the surface -of the earth, comes from the sun. Upon the hypothesis that the heat which warms our atmosphere comes directly from the sun —as the heat of the atmosphere at 2 o'clock in the day will average about 20~ Fahrenheit greater than it will from 2 o'clock at night till daylight-how can the question be answered, what becomes of the heat at night, which is received from the sun during the day? It is impossible, (upon the commonly received doctrines of physics) to give a rational answer to that question. The only rational answer that can be given to the general question-what becomes of a portion of the caloric or heat, at night, which warms the atmosphere during the day, is, that it is absorbed by the earth-that the sun's attraction during the day draws caloric from the crust of the earth, which is absorbed by the earth's crust at night, when that attraction ceases to operate-and thus the same atouns of caloric SOURCES OF CALORIC. 45 warm the earth's crust and its atmosphere from day to day —from year to year-and from century to century — except so far as it may be affected by volcanic action, and other extraordinary causes. Porter, in his Chemistry, says, heat is radiated into space from the atmosphere and the earth also. His words are: "At night when the sun is below the horizon, the waste by radiation takes place very rapidly, and the earth and air grow colder in consequence. * * * As the earth, being solid, is a better radiator than the air, it cools most rapidly, sending out its heat through the air into space." Such statements are based upon the false assumption and hypothesis-that caloric has no more affinity for matter than for vacant space, but has an unlimited tendency to dffusion throughout the regions of space, and to form an equilibirum therein. If such were the case, not only the earth and all the planets, but the sun and the stars also, and all their planets, would, in a comparatively few years, lose nearly all their heat, and cold and frost would reign throughout the universe. The theory which I have suggested seems to me to be the only one consistent with the stability and permanency of our earth and solar system, in their present condition; and they have undergone very little change, in temperature or otherwise, during many thousands of years. Above the 42d degree of latitude the ground in our Northern and North-western States, generally freezes in winter from two to three feet deep. The frost comes out of the ground, mostly in March, but some of it the last part of February; and many facts indicate that the frozen ground is thawed mostly from the under side, by reason of the internal heat of the earth. It is often found that there is no frost, or scarcely any in the woods, the latter part of the winter, when the snow is deep; and it is a common remark among farmers, that the snow has drawn the frost out of the ground-when in fact the ground has been thawed by the internal heat of the earth. Warm rains sometimes melt the frozen earth at the surface 46 SOURCES OF CALORIC. for a few inches in depth,-when there is frost lower down; but persons employed in digging graves at all seasons of the year —-(in winter and early spring, as well as in summer), when digging graves early in the spring when the firost is coming out, have generally found some frost at and near the surface-when there was none below eight inches or a foot in depth. If the frost were taken out of the ground by solar heat, coming directly from the sun, or from the atmosphere, a foot or more upon the surface would often be foun d thawed, when there was a foot or more of fi'ozen ground lower down-but such has never been found to be the case. The ground often he.aves in winter, raises posts several inches out of their places, throws down or shatters stone walls, and makes great cracks in thi ground. The forces which produce such effects, must be internal-not external. The following statement of curious facts, showing that deep snows melt from the underside-from the effects of the heat of the earth, and not from the heat of the sun, is taken from a communication published in the New York Observ r, of January I6th, I873, entitled, LUMBERING IN NORTHERN MAINE. The writer says: "Our winter snows are usually from four to seven feet deep, and it takes an Aristook horse and driver both to keep the track; and then sometimes in the coldest weather, the bottom drops, or the teams break through, when the heat of the earth has melted away the once trodden' andfi-ozen path. I have seen these deep snows itn the woods beg n to run at tha bottom, so as to raise the water in the rivers, and cut away the ice in the coldest weather." The roots of maple trees spread out near the surface of the earth, and do not run very deep into the ground-rarely more than two feet deep. The sap riuns fi-eely the latter part of February, and early i.n March, when it thaws during the day and freezes at night; but long before the firost is all out of the ground; and yet the frost must be all out where the most of the roots are situated. Nothing but the internal heat of the earth, drawn forth by the sun's attraction, could so affect the roots as to make them send the sap up into the bodies of the trees; and it SOURCES OF CALORIC. 47 would be impossible for roots, situated in frozen ground, to send up sap. Hence the conclusion, that while there is still a few inches of frozen ground at the surface of the earth, there is none lower down, where the most of the roots of the trees are situated. My reasoning leads to the conclusion, that though the sun is composed of the same elements of matter as the earth in a molten state of liquid fire, it never emits, radiates, nor sends to the earth, nor into space, either fire, or any other element or substance; that while it operates upon and attracts every thiing within the sphere of the solar system, and occasionally draws to itself and swallows up meteors and small bodies of nebulous matter floating in the realms of space, it sends out and emits nothing; and instead of constantly diminishing by radiating heat, it is actually increasing by-swallowing up small bodies which, in their erratic course, come so near the sun that they can not resist the influence of its attraction; that the earth and all the planets and floating bodies within our solar system, as well as all the stars and planets in the universe, have supplies of caloric-each having a supply proper to itself; that neither caloric, light, nor any other element-nor heat in any shape or iorm, ever passes from the sun or the stars to the earth; but that the interior of the earth being a great reservoir of liquid fire-the most subtle and mobile of all the elements of matter (except electricity), and the most powerfully influenced and attracted by the sun, the sun's attraction constantly draws from the interior of the earth, firom the side turned towards it, streams of caloric to the surface, and into the atmospherewhich to the eye look like rays or streams of light, coming from the sun, and to the sense of feeling seem like streams of heat; and that when the sun goes down and the attraction ceases, caloric, having a stronger affinity for the earth than for the atmosphere, a large pArlt of it is absorbed by the earth, to be again yielded to the force of the sun's attraction, the succeedilig day. 48 SOURCES OF CALORIC. The caloric that is near the surface of the earth, as well as that in the atmosphere, is subject, during the day, to two oposite inflaences-one, the stronger and predominant influence which draws it towards the sun, and the other, a weaker influence, which tends to draw it towards the earth-but is overcome by the attraction of the sun; while on the side of the earth opposite to the sun, the caloric near the surface and also that in the atmosplhere, is subject to only one influence-the attraction of the earth, which tenJs to draw and absorb it in the earth's crust. During the day, when it is subject to the attraction of both the sun and the earth —the former attraction being so strong as to overcome the latter, and to draw caloric from the crust of the earth into the atmosphere and towards the sun-its affinity for the earth, firom which it is drawn, is so strong, that it tends to draw the earth with it-as the attraction of the moon and sun also, operates upon the surface of the ocean, and cause the tides. As more caloric is thus drawn from the crust of the earth during the forenoon, when any given meridian is rolling towards the sun, than in the afternoon, when the same meridian is rolling from it, and as this action of caloric is upon one side only of the earth at a time; and the force is most strongly exerted upon only about one-fourth part of the earth's surface, the tendency of its influence is to turn the earth on its axis. To this action of caloric, caused by the sun's attraction, I attribute the diurnal revolution of' the earth and planets upon their axes. I know of no other force which constantly operates in such a mode, and with sufficient power-to produce such revolutions of the earth and of the planets, which revolve around the sun-and I can account, in no other mode, for the dual revolution of each-once daily, and once annually. The caloric which is thus drawn from the crust of the earth daily by the sun's attraction, carries with it more or less aqueous vapor, which supplies the atmosphere with clouds and the earth with rains and SOURCES OF CALORIC. 49 dews. By that operation, which is often visible to the eye, the sun in common parlance is said to draw water; and thus the moisture is drawn from the ocean and supplied to the earth-which is necessary to support both vegetable and animal life-and the earth is thereby rendered capable of supporting a vast population of rational beings. If the attraction of the sun be the sole agency which moves the earth and the planets, in their respective paths around that central orb, the caloric proper, and belonging to each, constitutes a great and necessary co-operative agency, which aid, in turning them upon their axes, and fitting them for the abodes of living beings. 4 CHAPTER VI. A NEW THEORY OF LIGHT, BASED UPON THE PRINCIPLE OF ATTRACTION, AND TIlE ACTION OF CALORIC. Twro theories of light have been forlned, xuliich in some measure divide the scientific world —one known as the corpuscular theory-that light is constituted of elements of matter similar to caloric-constantly emitted by the sun, thle stars, and by all burning bodies and flames of fire, and radiated into space at the inconceivable velocity of nearly two hundred thiousand miles per second. This was, until within a few years, the commonly received theory; and vet if it were true, the sun and stars would gradually lose their light and heat, and their substance also, and eventually become exhatisted-and both light and heat would finally be equally diffused through the realms of space. If that theory were true, there would and must be a tendency to a constant and universal diffusion of both light and heat; and to a rapid destruction of the sun, and of the present systems of worlds which constitute the universe. knothler and more modlern theory, is based upon the assurged existence of an imponderable elastic lumniniferous ether, pervading all bodies and infinite space, which is capable of transmitting a vibratory motion with great velocity —and that both liglht and heat are mere results of the undlulations and vibratory motions of that ether-or the ether itself in motion. The theory denies the existence of caloric as well as light, as distinct elements of matter, as not proven; and yet it substitutes in their stead, by mere assumption and without proof, the existence of a subtle ele ON LIGHT. 51 ment of matter, which the chemist can not detectthough it is assumed to plervade the whole universe, and to be the principal force therein; and some atsuine it to be the only force. Some who hold to the theory go so far as to make the assumed ethifer not only a substitilte for caloric and light, but also for electricity —and the tendency of the reasoning of those who adopt the theory is, to make the supposed ether a substiiute for all the forces of nature-including the chemnical affinities as well as gravitation, magnetistn, and tile vital forces. My theory ot light is very different from any which has been heretofre presented to the public mind. It is based uponl the principle of attraction and( the action of caloric. It is that the sensation of lirght arises from the attractive force of the sun, stars, or any bi:lze of fire-or of any subs'ance or elemnent of matter upon which the sun, stars, or a blaz,. of fire, or matter in tlie process of combustion in the atmosphere, is operating and illuminating by its power of attraction. The theory is, that the sensation of ligilt arises from the action upon the organs of sight of free caloric-e iitted by the blaze of the suin or stars, or b;, a burning lamp or flaine of fire. That it is caused by the direct attractive power of caloric in a state of flame, or in a very concentrated state, which produces a white or red heat in iron-or by the attractive force of any substanlce in nature, upon which such blaze is operating. The principle of attraction is universal. Its operation between all the bodies and compounds as well as between all the elements of the uiiverse, is recognized by science and( scientific men. It constitutes the forces severally known as the power of cohesion between elements of matter-as the chemical affinitiesas gravitation-sas nlagnatismn an(l electro-magnetism -and as the vital forces; and to say that it constitutes the force which causes objects illuminated by a blaze of fire or free caloric, to stamp their image or picture upon the organs of vision, is only making a j52 ON LIGHT. new application of a well known principle or power. It is only extending the principle of attraction to explain the phenomena of sitht-of which no satisfactory explanation has been heretotbre given. It serves to explain also the images and pictures formed by the daguerreotype and photograph processes, as well as those of a more temporary character —made upon mirrors and the polished surfaces of marble and various metals. That there are intimate relations between caloric, or fire in a state of blaze, and what we term light, is obvious to all. The real distinction between them may be illustrated as follows: Whether the blaze of a burning fire be confined in a stove or nothing intervene between it and the person, atoms of caloric are emitted from it in all directions-which often come in contact with persons, or with other living animal organisms; and when they do so, they excite sensations of heat; while light is only the attractive force of a blaze of fire, or of the sun-operating directly upon the optic nerve of the eye. Caloric is an element of tuatter —while light is only the attractive force of that same element. Clear transparent glass, intervening between a blaze of fire and the eye, obstructs nearly all the atoms of caloric emitted by it, and prevents any or much sensation of heat arising from such emission; but it does not obstruct the operation of the attractive forces of the blaze, upon the nerves of vision. The use of' the spectroscope in eclipses has established the fact, that the surface of the sun and the atmosphere surrounding it, are in a blaze, and constitute a blaze of tire-arising from the combustion of such metals and elements as compose the crust of the earth. To light our houses and other buildings, streets, vessels, railroad cars, and engines, we burn oil, tallow, coal-gas, and light fagots of wood. Any thing that will burn, and make a blaze, produces by burning, what we term light-that is the blaze so operates upon our organs of vision as to excite the ON LIGHT. 53 sensation of light; and it is difficult to conceive how it can be done, except upon the principle of attraction -by supposing that a blaze of fire so operates upon all objects within the reach of its influence, as to cause them, by the power of attraction, to print their images upon the organs of vision —as they mnake more permanent images upon the metal plates of the photographist. The church which I attend has a triplet window, or three long narrow windows of stained glass, over the front door, at the west end of the building. WVhen standing in my seat in the forenoon, with my back to them, some forty or more feet distant, I often see those three windows pictured in miniature in one of my glasses before my eyes-with all their various colors, figures, and forms. The phenomenon can not be accounted for on the principle of reflection of the sun's light from the windows, or its tr;insmission through them; for it occurs when the sun is not shining on them, and often when the sun is so obscured by clouds, that it does not shine upon the building at all. It seems to me impossible to account for such phenomena, except upon the principle of attraction-that when the sun is acting upon the atmosphlere upon tile outside of the windows-though not shining directly upon them, or when obscured by clouds, yet the affillity between the glass windows and my eye glsses, is such, and the power of attraction so strong, as to forml a picture of the windows uponI my eye-glass; which is conveyed to the mind by the direct action of the picture upon the organs of sense-by means of the power of attraction. Mv table in my study stands before a north window, and often when I sit with my back to the table and window, I see in the edge of one of my glasses a picture of the houses, fences, yards, and persons on the opposite side of the street, from 1oo to 150 or more feet distant. Stand upon a sidewalk in a city or village, before a window of a building upon the south or east side of 54 ON LIGHT. the street, in the forenoon, when the sun is shining, or upon the south or west side of the street early in the afternoon, and look into the window upon a level with you, and you will see before you not only the contents of the room into which you look, but also your own picture, and a picture of buildings, fences, yards, and landscape (if any in view), behind you, upon the opposite side of the street. That such an effect may be produced in a striking manner, the sun should not shine upoil the window throllgh which you look, and there should be much less light upon the inside than upon the outside of the window. It is easy for any one to test the correctness of this statement, and to see for himself how vivid, bright, and perfect the pictures ar —thus formed and presented to the eve; and he may thus realize the truth of the theory, that pictures of objects ale formed, and human vi-ion caused-not by the reflection or action of any substance called light-nor by the undulations of a supposed ether-but by tile power that anv object upon which the sun is shining, has to operate upon, and form its picture upon the polished surface of such substances as glass and other metals, and also upon water, and to make the picture so vivid, th~at the picture itself operates directly upon the organs of vision. Some wouldt attempt to account for such phenomena upon the principle of the reflection of light from one object to another-from objects to mirrors, polished plates and glasses, and back again to the organs of vision; but if lirlmt be a material essence or element, capable of,eing reflected in that mo(le by a sufficient force, what is the force which puts it in motion and causes the reflection, and when put in motion, how is it possible to conceive that any element reflected in all directions from objects, could bring with it to tLe organs of sight images or pictures of both forms and colors of the objects from which it comes? and how is it possible to conceive that undulations or waves of ether can bring with them to the ON LIGHT. 55 eye, images of the objects from which they come? No one to my knowledge has ever given a rational explanation, or even attempted to explain how images or pictures of objects are, or can be conveyed to the organs of sight, by particles of light reflected firom themn —nor upon the theory of the undulations of a supposed ether. But upon the theory of attraction, the etiect of objects upon the organs of sight can be understood, and rationally accounted for. It is laid down as a rule in optics that the angle of reflection of light corresponds with the angle of incidence. This is very true; but the rule applies only to those images of objects which come to the eye firom mirrows, from the smooth surface of glass, or from the polished surface of marble, or some of the metals. The sensation of light which conies directly fromn objects to the eye, comes from all directions, without any regard to the angles of incidence with which light may -trike them. This fact of itself shows very satisfactorily to my mind, that the objects themsalves act directly upon the organs of vision, by the power of attraction, without the intervening agency of any medium whatever. It is said that the moon shines by means of light coming from the sun, which is reflected from the moon to the earth; but it may be observed, that the light at fiull moon, appears to come from all p:rts of the moon's disk, or halt globe presented to the eye, and Nwithout any regard to the angles of incidence with which it may come from the sun to the moon, or the former may act upon the latter, by its power of attraction. Though the nature and properties of caloric, light, and electtricity, the vital forces, and many of the forces of nature, have never been fully ascertai-ned; and many doubts and differences of opinion in relation to them exist among scientific and learned men; yet there is at this day, no doubt, among intelligent men, of the principle of Universal Attraction, and that it is the governing force and power of the Universe -except so far as the Universe is governed by the direct action of the Divine Mind. 56 ON LIGHT. The attraction theory of light involves no new mystery. On the contrary it is based upon principles of science well established, and acknowledged by astronomers and chemists, philosophers and physicists, of all classes. It explains and obviates many diffictllties, which are inexplicable upon either of the theories of light which have been heretofore suggested. When the sense of sight can perceive, that by means of some physical agency, power, or force, every material object acted upon directly by the sun or a blaze of fire, so acts upon the surface of water, glass and every polished metal surface, as to form upon it a picof itself, the mind can easily conceive and understand how the same power can make a similar impression, and form a similar picture, upon our organs of sightwhereby we perceive the object; and that such power or force must be the same, or analogous to the powers which we term gravitation, chemical affinity, and attraction. Ganot in his Physics, gives the law of the intensity of light as follows:-The intensity of illumination on a given surface, is inversely as tile square of its distance from the source of light-Other authors have stated the law of the intensity of light in the same manner, illustrated it by practical examples, and proved it by a mathematical process. The law of Universal attraction of distant bodies for each other, is the same, that is to say, the power of attraction diminishes as the square of the distance of two bodies from each other increases. Why is the intensity of light and the power of attraction the same, unless light is one of the phenomena of attrac:ion? Caloric, like liquids and gasses of all kinds, will pass through crooked tubes and passages in any and every direction-and so do sounds-and so would lighzl, if it were mere vibrations, or was caused by vibrations of ether-but we know that light, and the attractive force of the sun, stars, and pli:nets, all operate only in direct and straight lines. And hence we have eclipses-because the sun's attractive force, ON LIGHT. 57 which causes light, can not pass around the moon and operate upon the parts of the earth's surface immediately be hind it. Tile decomposition of light and its division by means of the prism, into seven distinct classes-each having a distinct and different color, tends to prove the material character of the element or substance whith produces in the eye, tile sensation of light. How is it possible for a wave of ether to be divid(ed into several distinct classes-each having a color difterent front all the others? When a prism is held towards the sun, and the rays of caloric pass through it, they appear to be refracted and bent oot of their direct course-that is, effects are re-produced by the force of attraction, which present, according to the different degrees of their retraction, the seven primary colors of light; and also heat, at the same time. Put the end of a bar or rod of iron into the fire of a forge, or into a blacksmitlh's fuilrnace, raise the heat, and take it out occasionally and examine its condition, while in tile process of hteating, and it will be found to have, first, a reddish blue color, indicating a small degree of heat-then a yellowish color-then a bright red color, indicating a high degree of heat, snifficient to render it malleable, and fit for hamnmering and welding-and by continuing the iron in the fire, and increasing the heat, it finally attains a white hreat, before it fuses. Such experiments show, not only that heat and light are caused( by the same element of natter, but that the difeirent quantities of caloric contained in the iron at different perio(ds, during the process of heating, give it different colors, and change the color from violet or blue to red, and finally to a white heat. The color of light depends upon various thingsIst, upon the quantity of caloric contained in thle thing radiating the light, or in its surface. 2d, On the degree or angle of its refraction-in the clouds, or in a prism. 3d, On the medium throughl which it comnes 58 ON LIGHT. -whether through stained glass, or pure- white glass -through a clear sky, or through a cloudy or hazy atmosphere. 4th, On the character of the burning material that produces the flame, which causes the light -and whether it is perfectly or imperfi ctly consulmed. The spectrum of the sun, during an eclipse, is believed to show the materials of which its burning atmosphere is composed-and to reveal to the eye of man, the existeince of some of the same metals whiclh are coinmon in the crust of the earth. Could waves of ether, coming millions of miles, show such things? The division of rays of light by the prism, or clouds, into seven distinct colors, is not a real division of molecules of matter, into seven distinct elements. On the contrary, it is only an appearance of division, produced by the attractive force of rays of caloric passing through the prism, or through vapors and clouds in the atmosphere, and being thereby refracted, or the impression reproduced-the greater the degree of retraction, the darker the color produced. It the decomposition of light, and its division by means of the prism, or clouds, into seven distinct classes or elements, each having a distinct color, were real, it would prove most conclusively the material character of light, and that it is a compound. composed of seven distinct elements of matter. The different colors of light, produced by clitfi.rent degrees of refraction, are not consistent with the vibratory-ether theory of light. Tile theory that light is the mere undulation of a luminiferous ether, was suggested by the fact, that sound is produced by vibrations of air and other substances. The sensation of sound is produced by the vibration of substances, of which our senses can, and do take cognizance —while the elastic, luminiferous ether upon which the undulatory theory of light is based, is a pure assumption-a mere hypothesis, that something exists, and fills all space, which is so subtle as to be not only beyond the reach of the senses, but also beyond the reach of chemical analysis-and be ON LIGHT. 59 yond the power of the microscope and spectrosf ope, and all the philosophical instruments invented by man. There is, in fact, no analogy between the nature of sound, and that of light. Let uis examine the propagation of sound, and compare it with that of light. Sound is usually transmitted throllah atmospheric air at the rate of only 1,093 feet in a second-through water, over 4,700 feet per second-and through iron, I6,822 feet per second -the velocity depending npon the density and elasticity of the material by which it is propagated. Apply this mode of action to light. It light be propagated like sound, and by means of ether so subtle as to be beyond the reaclh of the senses, and of all human tests and powers of investigation, the velocity of its transmission, in such an attenuated Inedium, would be only a few feet to the second-instead of being instanter, or about I86,ooo miles to the second, as astronomers affirm it to be. Careful experiments, made by scientific men, have satisfied them that sound cannot be propagated through a vacuum, and that both heat and light can be so propagated. Such results being flatly contradictory to their favorite vibratory theory of heat and light, they adopted the tar fetched hypothesis of a luminiferous ether, filling all space —-a..d thus filling the supposed vacuum, and propagating the supposed waves of heat and light. The supposed ether is so subtle that the air-pullmp cannot affect it-so subtle that it is beyond the capacity of man, with all his inventive powers, to produce a real vacuum. The theory is so fine spun and fanciful, tlhat it resists all the tests of common sense, which Lenders it impossible to refute it, to the satisfaction of its votaries, however absurd it may 1be. But let us assume all space to be filled with an extremely subtle and attenuated elastic ether, the vibrations and( waves of which are supposed to caluse the sensation of light, the difficulty is not overcome by such an hypoticsis; the question then arises, and 60 ON LIGHT. forces itself upon our attention, what power puts the ether in motion, and maintains its constant vibrations in every direction, from every point to every other point in the universe, (as light is manifested,) at the wonderful velocity of I86,ooo miles per second? Nothing short of the direct aztion of the Divine Mind, or the animus mundi of the Pantheists, would be sufficient to maintain the constant vibration of the assumed ether, and to produce the effects and phenomena which we call light. The assumption and existence of an elastic ether does not warrant such conclusions as to its vibrations and effects, as have been de duced by its advocates. The hypothesis involves a series of assumptions, which seem to me not only without proof, but inconsistent with the phenomena of nature, with human reason, and with the results of science. If the sun be refereed to as the cause of the vibrations of the ether, which are said to cause the sensation of light, the question may be asked-How can the sun produce such action? Does the sun move the ether by the power of attractiol-by repulsion —or by the emission of corpuscles of matter, which pervade the ether, move it, and keep it in motion? If the sun act upon the ether only by means of eorpuscles of matter constantly issuing from it, then the waves of ether could only move in one direction-from the sun; and how does tihe theory, in such case, liffer Ftiolr the old corpuscular theory of light? Light co'nes to the eye from all directions-from the north and the south, the east and the west-and fi-om all points of the compass, at the same time. It comes not only from towards the sun, but from the opposite direction. It comes horizontally and perpendicularly, and firon all grades of angles with the plane of the horizon. It comes not only firom the sun, but fi'om all substances upon which the sun's power,f attraction is directly acting. It comes, also, firom artificial blazes of firefrom lamps, candles, and gas-burners, lighted by man; and its illuminating power radiates in all directions ON LIGHT. 6 from such artificial sources. What secondary cause, other than universal attraction, exists in the universe, which can act in every direction, at the same instant of time, as light comes to the eye? How is it possible to conceive that waves of ether can move in all directions, at the same instant of time? And if so, what can move them? Is the assumed ether a self-acting element? Can it act except when, and as it is acted upon and attracted by other elements of the material wvorld? If so, it acts differently from all known material elements of the universe, and can be likened in its action only to the Divine Mind, and to the intellectual substances which form mind, as distinguished fiom matter. Such an ether could not be distinguished from the animus munzd' of the Pantheists. Perhaps electricity may be referred to as analagous in its character and action to ether. But even electricity is not a self-acting element. It acts only by means of its affinity for, and as it is attracted by, other matter; and it moves only in one direction at the same instant of time-and not in every direction, as light comes to the eve. Electricity has several known and striking characteristics-none of w}hich can be affirmed of the assumed ether. ist. Electricity is a material, imponderable element, which the senses can take cognizance of, and which the chemist can collect in glass jars, and accunulate for use. 2d. It is an element which has wonderful force and power inherent in it, by means of its active affinities for other matter. 3d. It can be moved by human agencies, by mneans of a battery and certain machinery, through an iron or copper telegraph wire, with great velocity; but its velocity in a less dense medium, in the clouds and in the atmosphere, is not ordinarily so great. The existence as an element of matter, and the inherent force of electricity, and the velocity with which it is transmitted, are all matters of fact, well 62 ON LIGHT. ascertained, and not mere assumptions; while the supposed ether, and the undulatory theory of light based upon it, involve at least three assumptions: Ist. The existence of an elastic ether, filling all space, is assumed-there being no proof of it. 2dC. It is assume(d that the supposed ether is in constant motion —by reason of its own inherent forces and tendencies, or by reason of some other power or force acting upon it; which has not been, and cannot be pr-oven. 3(1. It is assumed that the sensation of light is cause(l by the vibrations and undutllations, or waves, of the aissutmed ether. Assuming the existence of an elastic ether, is not of itself sufficient to account for the phenomena of light. It is necessary to assume, also, an inherent or external l)ower or force sufficient to move the ether, and to produce constant undulations and waves. The theory is based upon a series ot assumptions. It may be remarked, also, that elastic substances are always destitute of active force, and have a tendency to incriia. This subject is worthy of examination, and of the consideration of scientists. and of the public. If my vicavs prove correct, they will have a material influence upon the progress of physical science. CHAPTER VII. THE UNWARRANTED ASSUMPTIONS AND FALLACIES, MYS'TICISM AND SOPHISTRY, INVOLVED IN THE VIBRATORY-ETIIER THEORY OF HEAT AND LIGHTA.N'D ALSO IN THE SOLAR-E]MISSION THEORY-AND TAUGHT IN BOOKS OF SCIENCE. AMechanical pzhilosophy of nature. The mechanical philosophy of nature teaches that the sensation of light is caused by the vibrations of a lumnizzfer'ous ether, which pervades the universe and fills all space-that heat is produced by motion and friction, witthout the agency of any such elementary substance as caloric-that vegetable and animal organisms, and life itself, are produced and operated without the agenicy of any such elementary principle as the vitalists term the vital principle-and that mind itself is the results of organization, and is produced with all its filculties, powers, and phenomena, by the forces of naturle-operating upon mechanical and chemical principles-without the agency of any such element or entity, is an intellectual principle, or intelligent substance. The mechanical philosophy of nature is based. to a large extent, upon unwarranted assumptions and fallacies, is vague and incoherent in its principles, unsatisfactory and mystical in its mode of reasoning, and arrives at conclusions which are inconsistent witi the experience, and with the common sense of mankind. It might, therefore, very property be termed, thle mystical philosophy. It is based upon a supposititious 64 GANOT S PHYSICS. ether, and upon motion-the existence of the former of which is assulmed, and can not be proved, and the latter can not be produced and maintained, without active forces, which the theory ignores. The motion, which constitutes the chief corner-stone Of the theory, cannot be produced and maintained, unless the assumed ether is the great cause of motion in the universe, and constitutes what was called by the anlcients, the animus mandi, the soul of the world-or the Pantheist's substitute for Deity. The foices and causes of action, motion, and change, as I maintain, are —Ist Universal attraction. 2d. Caloric. 3d. Electricity. 4th. The vital ortanizing element. And 5th, the intellectual principle-and perhaps magnetism should be added. It seems to me impossible to account for the phenomena of the universe, and for the faculties and action of the human mind, withLout the existence and cooperative action of all the five forces which I have enumerated, or the existence of something like, and equally efficient, as the animus mundi of the ancients, as a substitute for them. Neither chemical nor vital action —ignition and combustion, nor evaporation-fermentation nor decomposition, can commence or be maintained, without caloric; and yet the mechanical theory of 1heat repudiates caloric, and furnishes no sufficient substitute for it. Motion (as has been shown in Chapter III) is not a cause, but an effect, and must be supported by an active force as a cause, and cannot be a substitute for caloric, which is, itself, an active force, and an efficient cause of action. Ganot's physics. Ganot's Physics is used as a text-book in the University of Michigan, and is recognized as a work of high authority upon the subject. It teaches the mechanical philosophy of nature. In the first chapter, upon MATTER, FORCE, AND MOTION, he says: "In our attempts to ascend from a phenomenon to its GANOT S PHYSICS. 65 cause, w' assume the existence of pfhysical agents or natural forces. acting upon matter; as examples of such we have gravitation, heat, light, magnetism, and electricity "Since these physical agents are disclosed to us only by their effects, their intimate nature is completely unknown. In the present state of science, we cannot say whether they are properties inherent in matter, or whethfer they result from movements imapressed on the mass of subtle and imnponderableforms of matter difused through the universe. The latter hypothesis (I W is, however.generally admitted. This being so, it m iv be Iurther asked, are there several distinct forms of imponderable matter, or are they, in reality, but one and the same? It would seem that the latter op.'nidti (2) tends topreva,'i, as the physical sciences extend their limits." Comments. i. Tile hypothesis of the mechanical school, which attributes all power to motion, ignores and denies the existence of any active properties or forces in common matter, and refers all force aud action to some " subtle and imponderable forms of matter, dijfused through the universe " This is very vague- but what can that universally ditfused subtle and powerful substa ice be other than the animus mundi of the ancients-the Pantheistic substitute for God? 2. Again he says: "The opinion tends to prevail," that all the five imponderable forms of matter which he enumerates, to wit: gravitation, heat, light, magnetism, and electricity, are one and the same-constituting the same essence, which,in subsequent chapters of the work (on heat and light), he characterizes as an elastic luminiferous ether. That ether then is the great power which moves the universe,and causes all the action in it. I again ask-what can that ether he, but the Pantheistic substitute for Deity? Such is the mechanical philosophy of nature, which is substantially, thoughl very vaguely, taught in many of the schools of the present age. In Book VI., on Heat, Ganot says: "Two theories as to the cause of heat are current at the present time; these are the theory of emission, and the theory of undulation. On the first theory heat is caused by a subtle,imponderable fluid, which surrounds the molecules of bodies, and which can pass from one body to another. * * * On the second 5 66 GANOT S PHYSICS. hypothesis the heat of a body is caused by an oscillating or vibratory motion of its material part cIes, and the hottest bodies are those in wh ch the vibrations have the greatest velocity, and the greatest amplitude. Hence, on this view, heat is not a substance, bat a condition of matter, and a condition which can be transferre I from one body to another. It is also assumed that there is an imponderable elast c ethe/cr, ih;ch pervades all bodies and nfinite space, and is capable of transmitting a vibratory motion with great velocity. A rapid vibratory motion of this ether Pfroduces heat, just as sound is produced by a vibratory motion of atmospheric air; and the transference of heat from one body to another, is aftected by the intervention of this ether. * * * In accordance with it (this hypothesis) hent zs a form of mot on." In Chapter VIII, on heat, treating of radiant heat, he says: "In order to explain these phenomena, it is imazined that all space, the interplame aiy spaces, as well as the interstices in the hardest crystal or the heaviest in tal in short, matter of any kind is permeated by a med umm having t e piroperties of a #uid of nfinite tenuity, called ETHER. The particles of a heated body, being in a state of intensely rapid vibration, commnnicate their motion to the ether around then, throwing it into a syFcmn of zwaves, which travel thr. ugh space and pass from one body to another. with the velocity of light. When the undulatclions of the ether reach a given body, the motion is again delivered up to the particles of that body, which in turn begin to vibrate, that is the body becomes heated. This passage of motion through the hypothetical ether, is termed radiation, and a so-called ray oftheat, is merely the direction of the motion of one series of waves." Comnents. That it is a mere hypothesis, based on the assumed existence of an elastic ether pervading the whole universe, zs admitted; and yet, the whole process and action of thle assumed ether, seems fanciful and impossible, because palpably inconsistent with the common phenomena of the production of heat by combustion; and it does not even attempt to explain the process of combustion, and how it usually coin mences-nor how it is naintained. In the Book on Light, Ganot says: STEWART' S PHYSICS. 67 " In order to explain the origin of light, various hypotheses have been made, the most important of which are the em ssion or corpuscular theory, and the undulatory tk. ory. * * * On the undulatory theory, all bodies as well as the celestial spaces, are filled by an extremely subtle elastic medium, which is called the luminiJerous eth r. The luminosity of a body is due to an infinitely rapid vibraory motion of its molecules, which, when communicated to the ether, is propogated in all directions in the form of spherical waves, and this vibratory motion, being'thus transmitted to the retina, calls forth the sensation of vision." Comments. It would seem from the foregoing extracts, that the sensation of light does not depend upon the action of either comnbustion or the sun, but is independent of both-depending only on the assumed ether-and the vibratory motion of the molecules of a body, and of the ether. Not only the assumption of the existence of the ether is unwarranted. but all the reasoning in relation to the vibratory motion of the ether, and of the Inolecules'of bodies, is fanciful-mythical-entirely artificial, and does not carry with it even the semblance of truth-because it is contrary to the phenomena of nature. It is impossible for the molecules of a body to have a rapid vibratory motion, when the body itself is at rest. Stewart's Plhysics. Balfour Stewart, in his Lessons in Elementarv Physics, says: " When a body is greatly heated, we have reason to believe that'ts part cles are in a state of inten'e motion among tkemselves, although the body as a whole is at rebt." Comments. There are self-evident falsehoods, as well as selfevident truths. The proposition that two and two are four, is a self-evident truth; but the proposition that 68 STEWART S PHYSICS. two and three are six, is a self-evident falsehood, It requires no process of reasoning to show the falsity of the latter proposition, and the man who cannot perceive its falsity at once is incapable of reasoning correctly. There are in mathematics and philosophy many propositions and maxims, which are properly called self-evident truths; but Mr. Stewart has presenited one which may very properly be termed a self-evident falsehood, or error-because it involves contradictory and impossible action, which is obvious to the iind at.irst view, and no process of reasoning can make its falsity any clearer. The atoms and particles of a solid body -such as a stick of wood or a bar of iron, are held together by the attraction of cohesion; and while the body itself is at rest, is is impossible fbor its particles to be in a state of intense m-tion among themselves, as is affirmed by Mr. Stewart. That the particles of a body, while they are held together by the attraction of cohesion, and remain parts of the body, cannot move except as parts of the body itself, and when it is in motion, is a self-evident truth; aid it is idle and useless to reason with any one who denies it. Such incoherent ideas as are involved in Mr.Stewart's proposition, are scarcely wortly of serious consideration; and yet they form the chief corner-stone of the motion and fiiction theory of heat. Although Ganot has not clearly, and in so many words, affirmed any such proposition, yet it is involved in his system of reasoning, as well as in his conclusions. The question may be very properly asked-is there any absurdity too great to be conceived and believed by the human mind, and moulded into form and system by the fallacies and vagaries, the subtlety and sophistry of human reasoning? Before anyone attempts to answer this question, even to himself, he should consider well the religions and the theologies, the mythologies and the philosophies of the world, in the past as well as the present-and also what has been dignified with the name of science. STEWART'S PHYSICS. 69 WChen iron is put into a furnai(e and heated, how is it done? Is it heated by exciting motion in its particles and in the medium around it, as the mechanical theor'y assumes? And, if so, how is it done? The particles of the iron are held together by the attraction of cohesion-so that they cannot move, until the attl action of cohesion is destroyed, by melting the iron; and even then it merely settles down into the bottom of the furnace in a liquid form, and is there at rest, until the heat is raised so high as to reduce the iron to a state of vapor. The particles of the iron do not attain a state of intense motion among themselves, (as is affirmed by Mr.Stewart),during any portion of the process of heating or melting, for it would be imposstble for them to m,ve until the attraction of cohesion is destroyed by melting the iron, and that does not take pla.e until the heat is -raised to I,5oo deg. Cent. Hence the motion of the particles of iron (as stated by Mr. Stewart) could not possibly cause the heat —because the particles could not move at all, until the heat was raised to a great degree of intensity. The phenomena of the crust of the earth and its geological history, all attest that the interior o)f tt e earth consists of molten matter-held in a liquid state by what we call fire; and yet the mechanical theory of heat affirms. that there is no such thing as fire, as a distinctt element of matter-that wh}at we call ire is heat caused by matter in motion. How is it possible for the particles of matter, composing the interior of the earth, to be in such a state of rapid motion as to generate sufficient heat to melt them, and keep them in a liquid state, when the crust of the earth is cold, much of it frozen, and its particles are in a state of rest-except so far as they participate in the motion of the whole earth on its axis, and around the sun. If the heat in the interior of the earth be caused by motion, the question then arises, What causes the motion? Collbustion is the direct effect of fire or caloric, permeating combustible materials. Thongh friction may, by compression, develop a small amount of ca 70 STEWART S PHYSICS. loric from the surface of the things rubbed together, or from the atmosphere at the points of friction-and thereby originate combustioa-it is the fire itself. and the combustion produced by it, an(l not the friction, which consumes wood, coal, and other materials, and maintains and propogates the combustion. No such effects can be produced directly by motion and friction, without the agency of caloric as well as of combustion. If it were possible to conceive, that motion and friction can maintain as well as originate combustion, the question would then arise-what causes the motion? The marvellous effects of great cenflagrations could never be produced by motion and friction, upon the vibratory theory of heat. 7b maintain that theory, it is not suzffcient to ftccount tor the origin of heat and combustion in a few exceptional cases; but it is necessary to be able to show that heat and comnbustionare originated and maintained in all cases, by motion andfriction —without the agency of any such elementary substance as caloric, That caloric (:an be absorbed, and remain in a latent state, until drawn out by strong attraction, is beyond all questien. The earth itself is a great receptacle of caloric; but it is diffi,.ult to canceive how tmere motion, or the vibrations of ether or anything else, can be so absorbed, remlain for a time inert, and then be drawn out again into action, as caloric is. If the adherents of the vibratory ether theory of heat anid light held that ether is i/self Ca substance, known as heatand that it produces light by a vibratory motions, I could conceive how it acts. But in such case, they would abandon the vibratory theory of heat, and admit its material character; and wouldl only chanlgo its naine, and give the nam-le of ether to a material fluid, which tlie Rotnans called calor (heat), and ignis (file), more than two thousand years ago. It is adu;uitted by the adherents of all the theories of bieat, that it possesses great force and energy, andll that it often exhibits wonderful power. Is it possible to have any clear conceptions of force and energy, or TYNDALL ON HEAT. 71 of the cause of motion, as existing independently of substance? Tyndmal on heat. A work was published in London some years since, which has been republished in New York, entitled, " Heat, Considered as a Mode of Motion," by John Tyndall, F. R. S., etc. It is based upon thle assumned existence of a luminiferous elastic ether, pervading the whole universe, and filling stellar space; igno,res tile existence of any such elementary substance as caloric-man's most familiar friend andl usefill agent; ard presents and illustrates in detail, the vibratory, or mechanical theory of heat and light. It discourses with an air of learning of natural forces and lowers-of the motions and vibrations of the assumed ether-of tile atoms arcid molecules of matter-of mechanical processes, potential energy, dynanmical energy, and solar energy,-of the generation of heat, and the emission of heat and light from thie sun, and their radiation into space, as mere vibratory motion, not substance. The title itself, as well as inany of the views, and nuch of the reasoning contained in it, sounds like ia burlesque on commton sense, antd on the common experience of mankind. If that be science, it is science rutn into the ground; and yet it has been received with fiavor by great numbers of scientific men. It exposes to view in detail ttie absurdities of the vibratory -theory of heat, by ca-trying out its principles to their consequences, and attempting to illustrate their operations in practice. Many of his illustrations are brilliant and beautiful. Tney formin quite a curiosity shop-well adapted to please the conmmon mind, andt amnuse a popular audieilce, but of very little value in a scientitic point of view-for the reason that the plrin,.ipal views taken are falltacious, much of the reasoning incoherent and unsound, and many of the conclusions arrived at unwarranted. To build upon et:ier foundations and vibrato 72 TYNDALL ON HEAT. ry corner-stones, is like building upon blowing and drifting sands. A fabric built upon such foundations, cannot stand the test of time. It is quite time to have the principles of natural scieiice reviewed-some new corner-stones and new landmarks established, and new foundations laid, upon which to build the great fabi4c of human science. As an Am.erican citizen I am gratified by the fact, that the vibratory-ether theory of heat and light, did not originate in America-t}hat none of its vagaries were first conceived by citizens of my country-and that though many American authors have not had sufficient courage to repudiate it directly, as fanciful and unsound, very few have based their reasoning upon it. Prof. Porter, of Yale College, in his Principles of Chemistry, substantially repudiates the vibratory-ether theory. After stating both theories of light, he says: " The first, or Newtonian theory, enables us to explain the leading facts more simply Uln(l clearly, and is therefore employed in this work for this purpose. The definitions and laws of light are stated in the language of that theory." After stating the materi/al theory of heat, and also the vibratory-ether theory of it, he says: " In the present volumle, the former of the views which have been mentioned, is adopted, and heat, like ltl/t, is assumed to be an exceedingly subtle, ittpoznerable fluid. " Dr. Comstock, in his philosophy, adopts the Inaterial theory of heat and light also, and bases his reasoning and illustrations upon it. Prof. Johnston, in his Manual of Chemistry, treats the subject in a very delicate manner, without committing himself to either theory. He says: " Heat cannot be obtained separately from matter; it is invisible, etc. * * * It is not, therefore, believed to be material; but in describing its effects, and its relations to matter in general, we speak of it as an exceedingly subtle fluid, the particles of which constantly repel each other, but are attracted by other substances, as capable of beinll transmitted through space and the interior of GANOT' S PHYSICS. 73 bodies, and of being accumulated in quantities in them." Such lanruage does not properly apply to mere motion, which cannot be accumulatedl in quantities, in solid bodies, and can not be transmitted through them. Prof. Johnston states the material theory of light, and also the vibratory.ether theory, but says: " The whole language of optics is founded on this (the material) theory." American authors have generally stated the vibratory-ether theory, but have not attached much importance to it. Ganot's Physics. Ganot's 355th paragraph, on the radiation of heat, is entitled, "' Mobile equilibritum-Theory of Exchanwres," in which he says: "Prevost of Geneva, suggested the following hophthesis in reference to radiant heat, known as Prevosts'theory of exchanges,wh ch is g.nerally admt te:. All bodies,whatever their temperature, constantly rad ate heat,n all directions. If we, imagine two bodies at different temperatures placed( near one ano her. the one at a higher temperature will experience a loss of heat, its temperature will sink, because the rays it emits are of greater intensity than those it receives; the colder body, on the contrary, will rise in temperature, because it receives rays of greater intensity than those which it emIts. Ultimately the temperature of both bodies becomes the same, but he it is st'll exchanged between them, only each receives as much as it emits, and the temperature remains constant. This state is called the mobile eqail brium of temAeratu re." Tie samine theory of exchanges of heat is stated by Tyndall in the language of the wave theory. Conmments. Such are some of the strange theories and doctrines taugrhl in books and schools of science. That caloric is dr'awn by the force of attraction from heated bodies and fires, by and into cold and cooler substances and the surrotunding atmosp lere, is evident from coln 74 GANOT S PHYSICS. monl observation; but the hypothesis of Prevost, that two currents of caloric or! heat is runninc in the same chiannels or places in opposite directions at the same time-one of them from a hot place or body. to a cold one, and another in the opposite direction, from thie same cold body to the hot one, involves inconsistent and contradictory action, and is, therefore, a self-evident impossibility. We know that calo, ic, to a certain extent, tends to seek an equilibrilrn of heat, and is attracted by cold bodies, which attract and (iraw it from hot or warmer ones; but what force or lower can attract and (traw or force it in the opposite direction-from the cold to a hot or warnm bod)-as the Prevost theory of cxchanges asserts? \ hat evidence is there to support such a theory! Is not co:mmon sense, and all the evidence we have upon the subject, in opposition to that theory? I have not observed that any American author has affirmed, or stated with approbation, the Prevost theory -but Gallot say, " it is now universally admzitted,"by men of science I suppose he nllst mean. Catl science hing command the respect of men of commonseltse, it it sanction and affir-l such strange and absurd theories? Solar radfiation of heat. Ganlot says: " The most intense of all sources of heat is the sun. The cause of its heat is unknown; some have considered it to be an ignited mass experiencing immense irruptions-while others have regarded it as composed of layers act zng chenmically on each other, like the coaples of ta voltaic batte-y g'ivinR rise to electrical curr, nts, which produce lfght and solar heat. On both hypotheses the incandescence of the sun would have a limit"' "Different attempts, (Gantot says), have been made to determine the quant ty of heat annually enmitt d by t/he sun. M. Pouillet, by mneans of an apparatus which he calls a pi-rheliometer, lhas c lculat: d that if the total quantity of heat which the earth receives from the sun in the course of a year, were employed to melt ice, it would be capable of melting a layer of ice all round the earth of 35 yards th ckn ss. But from the surface which the earth exposes to the solar radia GANOT' S PHYSICS. 75 tion, and from the distance which separates the earth from the sun, the quantity of heat wh'ch the earth receives can only be p U()O. art of the heat emitted by the sun." Porter says: " The sun sends enough heat to the earth every year to melt a shell of ice enveloping the earth, a hundred feetdthick. * * * It is ascertained (he says) that a quantity of heat is g ven out from the sun in a year, which, if it all came to the earth. would melt a crust of ice nearly 4,000 miles thick." Substantially the same facts and results are stated as philosophical truths by other authors. Comments. Let us consider such calculations and their results, and the necessary consequences if true, of the causes which produced them. The evidence of balloonists, as well as. the vegetation upon the sides of the mountains, and the want of vegetation and the existence of eternal snows npon the tops of lofty mountains, all attest to the fact, that heat diminishes rapidly as you rise above the level of the sea —upon mountains, or into the atmosphere-indicating that no caloric, or heat in any form, comes from the sun, or is radiated from the earth into space. I have stated, in Chapter V, that all the caloric which is radiated or drawn by the sun's attraction from the earth into the attm,,sphere by day, is absorbed again by the earth at night-and that the same process is repeated from clay to day, from year to year, and firoma century to century.'P;ie Calorifi e theory, stated in that chapter, is the only one which is consistent with the phenomena of nature, and with the harmony and permanency of the solar system, and of the universe. WViat would be the necessary effects of the solaremission and radiation theory of heat, stated by Ganot andl other authors as scientific trut Is, and of the enormous quantity of heat and matter emitted from the sun annually, which their calculati6ns illvolve-sufficient to melt a crust of ice Ioo feet thick, surrounding the 76 GANOT'S PHYSICS. earth, when only a small fraction of the whole quantity emitted can reach the earth? Would not the first effect be, the gradual diminution of the sun's substance and power; and would not its complete exhaustion, and the dispersion into space of its substance andt energies, be only a question of time? Secondly, would not the tendency and the final effect be, to produce an equilibrium of heat throughout the realms of space, and to raise, gradually, the temperature of all interstellar space? WVould not a third effect be,,to accumulate rapidly upon the surface of the earth and the planets, the heat which they receive daily fiom the sun, until they become as hot as the sun itself? Would not the magnitude and heat of the earth and planets increase, as the sun loses its heat and substance, and diminishes in size? Would not the sun's power of attraction diminish with the decrease of its substance and heat,.until it ceased to have a controlling influence over the motion of the earth and planets-and would not the regular action of the solar system then cease, and the whole system fall into confusion? All these are pertinelzt questions for the solar. emission theorists to answer, and to dispose of satisfactorily, before they can maintain their theory. Authentic history reaches back nearly 3,000 years-monu mental history extends back many ages farther; and the evidences of geology extend back for an indefinite period, prior to the existence of nman and.11 these evidences attest that the surface of the earth and its tem!,erature have not materially'changed, since it was first inlhabited by man; and that the apparent size, heat, and power of the sun are the same as they were 3,000 years ago. In the face of suclh facts, as evidences of the unsoundness of their theories, how utterly worthless they are. In fact they serve only to mislead inquiring minds, and are worse than a firank acknowledgment of total ignorance upon.uch subjects. CHAPTER VIII. VIE\N'S OF THE ORGANIZING PRINCIPLE-OF THE FORMS OF LIVING ORGANISMS-AND OF LIFE AND INTELLECT. Elements of the human system. The constituent elements of the human body, and of all animal bodies, which tile chemist can detect, are oxygen anid hydrogen, carbon andl nitrogen, lime and phosphorus, iron and chlorine, and small quantities of a few other elements. All these exist in chemical comnbination-forming the texture of the solid parts and organs of the body, or float, like iron, in the blood. Every living organism, whether animal or vegetable, is also pervaded by caloric, as wvell as by an unknown element, which we call the principle of life, or the vital element. Electricity is also very generally diffused through animal organisms. Both caloric and electricity, as well as the vital element, are latent, and cannot be detected by the anatomist, nor the chemist. They can be determined only by their effects-by reasoning upon the subject, and by our knowledge of the tact that caloric pervades the earth and its atmosphere, and everything upon the face of the earth; and that neither animal nor vegetable life can exist without it. Electricity is much less abundant, but seems to, be nearly as generally dif fused as caloric, and pervades the nervous and muscular systems, if not the whole animal economy; and yet, if it were not for the fact that caloric and electricity can both be so concentrated and accumulated as 78 THE VITAL PRINCIPLE. to be visible to the eye, and to the sense of feeling, we should have no stronger or other evidence of their existence in living orgflnisms, than we have of the vital principle. Caloric is a solvent —not a cement. It holds no elements together; but permeates everything, enters between the atoms of all substances, separates them, and expands the whole mass or compound; and when very much of it is concentrated in substances, it disintegrates and melts them, and converts them first into fluids, and finally into gases and vapor. Though a certain amount of caloric must accompany the elements of matter that aie fornmed, or are ready to be formed into living organisims, to keep them in the right temperature andl condition to receive the plastic influence of the vital principle, yet caloric itself is not an organizing element. On the contrary, it is a disintegrating. dissolving, destroying element and force. Similar remarks will apply to electricity. It is a destroying, not an organizing element. A sb~ft of lightning is often as (lestructive as a cannon bail. The vital element, and forms of livinSg organisms. The vital principle is, in somc respects, analagous to caloric and electricity. Like them, it has no gravitating tendencies. It has peculiar inherent, active powers, forces, and properties of its own-having a strcng affinity for caloric, and for all the elements which enter into animal and vegetable organisms. It is an organizing element, which attracts and acts upon certain elementary substances; overpowers their citemn7 ical affinities; unites with them; arranges and moulds them into cells and tubes; forms them into living organisms-adapted to various activities, growth and development; and preserves them in life and activity for months and years. It overcomes'the attraction of gravitation, and carries the blood of animals upwards, and the sap of plants and trees fromn the roots to the branches. THE VITAL PRINCIPLE. 79 The organs of animals consist of tubes and cells, with muscular sides, in which fluids circulate, for the formation of animal fibre, and the Inaintenance and preservation of the animal economy. Not only the arteries and veins, nerves and spine, are tuhular, but all the orrgans of digestion and nutrition, secretion and excretion, are also tubular. Plants are formed in a similar manner- vith a succession of tribes in the roots, trunks, and branches, for the absorption, circulation, and transmission of fluids and food, fiom thle roots to the leaves. On the contrarTy, inanimate, earthy, mineral, and fluid substances, held together by the force of chemical affinities, are never tubular nor cellular, muscular nor fibrous-but the same, or nearly the same, in density and texture, in a111 their parts. There is no similarity between the form and texture of cr-ystals and stones, metals and earths, and those of living animal and vegetable organisms. Henice we may safely conclude that living organisms contain somie Lnknown element, whicll inanimate matter does not. It has been said that tlhe existence of a vital element is:1 mere assumption, an hypothesis or theory of life-uncertain in its nature, and incapable of positive proof. That is in sonme respects true. The essence and nature of both life and intellect are mysteriesbeyond the full comprehension of man; and so are the properties of matter, and the forces of nature. As we infer the properties of matter and the forces of nal ture firom the phenometla.,f the material world, and the experimental tests of chemistry-so we can infer the existence of a vital element, from the peculiar texture, forms, and action of anitnal and vegetable organisms. Dr. L. S. Beale, of London. in the preface to his Essay on the Mystery of Life, says: " Facts and observations on things living, support the idea of vital ty, and are not favorable to any mechanical or chemical hypothesis of life yet proposed." So THE VITAL PRINCIPLE. In the Essay, (p. 63,) he says: "I hold it, because I cannot escape from it; because the facts I know cannot be explained without the hypothesis." This is no new theory. Dr. Paine, in his Institutes of Medicine, devotes no less than seventy-seven sections to the subject of the vital principle, and vital properties. In section I64, lie says: " There is not, indeed, in the whole range of medical literature, one author, however devoted to the physical and chemical views of life, who does not evince the necessity of admitting a governing vital principle, as a distinct entitydistinct from all other things in nature.' In section I72, D1I. Paine says: "The principle of life, or life itself, may be summarily defined as a cause. * * * The principle is creative, so far as it combines the elements of matter in peculiar modes, and arranges the compound molecules into tissues and organs-in modes identical with those which came originally from the creative energy of God, who thus far imparted to the principle of life a formative endowment." It may be said thiat such action of the assumed organizing element, implies intellect, knowledlge, and wisdomn-working for the accomplislhment of definite ends and purposes. That is very true. Grant, that to accomplish such ends anrd purposes, mIust require intellect and wisdom. In fact, nothing slhort of infinite knowledlge, wisdom and power wouild seem adequa;te to prodl ce such mysterious action, and to the attainment of suich ends. But if we admit the existence of a Supreme Being, possessed of infinite creative power and wisdom, lind suppose that the Divine Mindl invested an element of matter with tile properties and qualities, affinities and powers, necessary and adequate to constitute it an organizing agent-tending to forrm and support such organisms as plants and animals, and to maintain an(l multiply them under certain circumstances, in accordance with certain prescribcd types stnd forms —the main difficulty vanishes; and it is as easy to conceive that God creates plants FORMS OF ORGANISMS. 8I and animals, and supports animal and vegetable life, by such means and methods, as by any other. Distinctions between matter and force —organization and intellect. The vital principle and caloric are causes-not results. Organization is the result of the operations of a living, organizing principle. Organization is not the cause of life, but the effect and medium by which it acts, and is manifested. The chemical affinities are forces or properties inherent in matter-not original elements. So also is gravitation; but caloric, electricity, and the vital, organizing principle, must be original elements of matter-each having its own peculiar powers, forces, and tendencies. And such, we have no reason to doubt, is the case with the cause of intelligence. Cognitions and perceptions, ideas and opinions, are all the results-not of organization alone —)ut of the action of an intelligent substance or spirit-the material organization being only the medium in which an intelligent principle acts. Sensation, and the cognition or consciousness of sensation, are very different things. The first is a vital action, caused by objects operating upon the nerves; but the latter is an action of the intellect. Physical impressions upon the brain are very different things from the intellectual perceptions and cognitions of such impressions; and conceptions and ideas which arise from the workings of the intellect, are different from those which are the results of physical impressions upon the senses. The distinctions between sensations and impressions, which are physical in their nature, and the perceptions and cognitions which result from sensation, have been very generally overlooked by philosophers of the various schools of materialists. 6 82 INTELLECTUAL PRINCIPLE. Two or more natural causes necessary to produce pijyszcal action. No one element of matter can act of itself, and by means of its own inherent powers and properties. Motion, and all change and action produced by physical causes, require two or more physical agents, elements or substances-having such affinities as to act upon each other. All chemical action arises from the affinities of two or more elements or substances, which mutually attract each other. Gravitation depends upon attraction. The sun, the earth, and the planets, all mutually attract each other, which causes their movements in their respective, paths. No one could move, if it were not for others acting upon it, and reciprocating its action. Even such mobile elements as caloric and electricity are set in motion by the reciprocal attraction between them and the sun, the earth, the atmosphere, and the clouds. They can act only by means of such mutual attraction; that is, by the concurrence of two or more elements, acting upon each other. Intellect distinguished from unintelligent matter. Nothing in existence but spirit-pure intellectcan act of itself alone, without the exciting influence of anything else acting upon it. On the contrary, much of the phenomena of human action indicate that the mind is an active principle-capable of originating action, without any external influence acting upon it-and of acting, not only in accordance with its own intelligence and knowledge, but of resisting external influences-of refusing to follow the beaten paths to which it is accustomed-of refusing to att in accordance with its own knowledge and informationof acting arbitrarily, and in search of new truths and e w methods-of forming new theories, and acting in accordance with them. The freedom of the human mind arises from its INTELLECTUAL PRINCIPLE. 83 capacity to originate action, and to act of itself-without external influences. Its freedom is exhibited most conspicuously in its negative acts. Physical action is uniform, always the same, when the circumstances and the elements acting are the same —for matter must act in accordance with its inherent properties. Intellect acts with no such uniformity; for while it generally acts in accordance with its knowledge and information, it often acts arbitrarily-forms theories and opinions, dogmas and rules of action of its own, upon which it acts; and it frequently acts, not only upon mistaken views of the facts, and false theories, acquired by reading, and in the process of education, but also upon erroneous theories and opinions formed by itself. Hence there is no uniformity, and no certainty, in human reasoning upon any subject that does not fall within the domain of mathematics. Two minds rarely take the same views of things; and never reason precisely alike upon questions, other than those of a mathematical character. Physical action is uniform, but mental action is not uniform. CHAPTER IX. XrITALISM, SPIRITUALISM, AND MA'rERIALISMI, -AND THEIR ACTION COMPARED AND CONTRASTED. The vital principle, (as understood by those who believe there is such a thing), is a distinct imponderable element of matter, too subtle for the chemist or the anatomist to find; for it disappears when an organism dies. It is an unknown organizing principle, having affinities for oxygen and hytrogen, carbon and nitrogen, caloric and certain other elements of matter, on which it acts and exerts such a force as to overcome their affinities for other substances-to combine and organize them, and hold them in a state of organization. It exists in the tissues and organs as well as in the blood and other circulating fluids of man and animals; and in the living tissues and sap of plants; and is the builder and preserver of all living organisms. Spiritualism in its philosophical and Christian sense, is the doctrine that the intellect is a distinct intelligent entity or spiritual substance, mysteriously blended with the material organization of the brain, endowed with consciousness and capacity to take cognizance of things, to act, to acquire knowledge, aid to exist and retain some of its faculties after its separation fromn the body. It is not subject to the laws and forces of the material world, except so far as it is acted upon through the brain and nervous system.'We know its existence only from its acts, and from personal consciousness. Neither the chemist nor the anatomist can find it. It is beyond the reach of their investigations. Materialism, in the proper acceptation of the term, is the doctrine that mind is the result and effect, MATERIALISM AND VITALISM. 85 and forms the functions of the organization of elements of matter, of which the chemist can take cognizance-and not a distinct entity or substance. The effect of such a doctrine is, that the mind cannot exist after the death of the body; and if man's spirit cannot exist separate from the body, it is impossible to conceive how God can exist as a spirit; and hence materialism runs directly into atheism. The doctrines of vitalism have not been much developed except by physicians, in connection with medicine. Though they are entirely consistent with spiritualism-yet, because they uphold, to some extent, the development theory, many reject them. The functions of life result from, and are constantly sustained by the living or vital principle; the organization being only the instrument and meansnot the cause of such functions and powers. The evidence of this is, that the organization continues after death-but the functions of life cease when the vital element leaves the body. Tne vital principle holds a certain amount of caloric in living organisms, as necessary to vital action, and resists its escape; and thus it strongly resists the effects of extreme cold. It overcomes many chemical affinities, and dissolves many substances and dead tissues of plants and animals, and converts them into food, to form living organisms. It also overcomes the action of gravitation-and carries the blood and fluids of the human system up as well as down; and carries the sap of plants and trees, contrary to the laws of gravitation, from their roots in the ground, to their tops and branches in the air. These are conclusive evidences to my mind, that living organisms possess properties very different from the imponderable forces, and the ponderable elements with which the chemist is acquainted; and that it must be a distinct element of matter. All living organisms-vegetable as well as animal, are cellular, tubular, or vascular-having fibrous sides and a hollow centre, to hold and convey fluids to sup 86 VITALISM, SPIRITUALISM, AND port life, and produce growth and increase. On the contrary all combinations of inanimate matter, not organized by the vital principle, whether they be crystals or other solids, liquids or gases, are uniform, or nearly so in density and substance, from centre to circumference. They are never tubular nor vascular; and have no means of increase except by external accretions; by the action of chemical affinities. Living organisms grow from the inside-by means of food prepared and conveyed in their tubes and vessels; but combinations of inanimate matter, having no tubes nor vessels to hold and convey liquids and food, increase from the outside only. These facts, are of themselves, strong evidence that the former must contain an element of matter which the latter do not; and if so, it must be an imponderable element, which chemical analysis cannot find, or has not yet found. Dr. Payne in his Institutes of Medicine, section I64, says: " A vital or peculiar governing principle or power, in organic beings, has been recognized by all the most distinguished medical philosophers, at all ages of the science. It is the fundamental cause of growth, nutrition,and of all other phenomena of organic beings. It is in all but the vulgar acceptation, synonmyous with life; and life is therefore a cause and not an effect-as has been assumed by many distinguished physiologists." In section 2I6, Dr. Payne says: "The elements of organic compounds are very differently combined from those of inorganic. Hence has arisen the term vital a(ffinity, as denoting a property peculiar to plants and animals, by which all their elements are united and maintained in combination. When death takes place, chemical affinities operate, and resolve the organic into inorganic compounds, or into their simple elements." Molecules, germs, and animalcules. Molecules, germs of life, and animalcules floating in water, or in the atmosphere, are not chemical comnbinations of unorganized atoms of matter-but living organisms-having in some instances living parents MATERIALISM COMPARED. 87 though often formed by the vital organizing element, as the first stage of organization, and the first step in the process of spontaneous generation. Many of the phenomena of nature indicate that such organisms are formed by the inherent properties, affinities and forces of the vital element, acting upon inanimate matter. Natural solvents. Caloric is the most universally diffused and powerful solvent in nature. When so concentrated in combustible materials as to produce a flame, or consuming fire, it destroys the texture of substances and dissolves them very rapidly. It dissolves, melts into a liquid, and eventually into vapor, even iron and all the metals. Nothing in the natural world can withstand its disintegrating and dissolving power. The vital element is not only a cement but also one of the most powerful solvents in the world. It destroys the texture of both animal and vegetable substances, and dissolves them more rapidly than boiling water can-to fit them for food, for new organizations. Steam is the third solvent in point of power-after which comes hot and warm water; and the hotter the water the greater is its disintegrating power-thus showing that its power as a solvent depends mostly upon heat, and comparatively little upon water itself.. Strong acids actindirectly as solvents-the oxygen is held to their base by very weak affinities-by reason of its excess-and is more powerfully attracted by other substances with which the acids come in contact. Carloric only when in excess, and steam, have a direct tendency to disintegrate and dissolve substances and compounds; while the vital element and the oxygen in water and strong acids, tend to do so by counter action, by reason of a stronger affinity for some of the elements of the compound, than its atoms have for each other. The vital element dissolves animal and vegetable compounds, to fit them for, and form their elements 88 VITALISM, SPIRITUALISM, AND into new organisms. The chemical affinities have no such power. The action of caloric and steam, in permeating and destroying the texture of animal and vegetable substances, is not a chemical process, but a process which belonos to the domain of physics, rather than to that of chemistry. Digestion, assimilation and nutrition. Digestion, assimilation, and nutrition, are all vital processes, and very different from chemical processes. Digestion destroys the texture of food, dissolves it, and reduces it to a pulpy mass; assimilation selects and secrets the parts fit for chyle and blood-and rejects the feculent matter; while nutrition appropriates and forms first into blood, and finally into tissues of the system, and into nervous matter, the parts fit for such purposes. The vital process of digestion operates in direct opposition to the chemical affinities, for it dissolves, while they tend to unite and hold together —and it effects the dissolution of food in from two to four hours, which could be dissolved by the slow process of fermentation and putrefaction, only in as many weeks, and in some instances in as many months. Salt, vinegar, pepper, and other condiments, and alcoholic liquors, all tend to preserve meats and vegetable substances from putrefaction and decay; but when they are taken into the stomach'in moderate quantities with food, they stimulate the action of the stomach-and instead of resisting the dissolution of food, they aid and promote it, by stimulating vital action and the digestive powers. These illustrations show the differences between vital processes and chemical processes. They serve to show that neither animal nor vegetable organisms could exist, without agencies very different from the chemical and ordinary physical processes of nature. They also furnish as satisfactory evidence of the existence in nature, of an organizing vital element, which MATERIALISM COMPARED. 89 is the constructor and supporter of living organisms -as human consciousness and mental actionfurnish of the existence of a soul or intellect, distinct from, but mysteriously blended with the material organism of man. The evidence of each is of a similar character; and the existence of each is denied by one of the schools of materialists. Materialism. The materialists of the chemico-mechanical school, assume, without proof, and contrary to reason and all the evidence we have upon the subject, that life and intellect are the results and effects of the organization of the animal system, and have no other cause. But the question may be asked, what causes and maintains such organization? It is very certain that chemical affinities and forces can never form organizations adapted to the phenomena of life, growth and development; that though a certain amount of heat is necessary to support life, and animal and vegetable growth, yet it is of itself a solvent, and when in excess, it is a destroying element, and never an organizing agent; and that there is in nature no element or force, known to the chemist, which is capable of acting as an organizing agent, with power to operate upon and form inanimate matter into living organisms. Hence the real question is, what forms and maintains animal and vegetable organizations And the further and still more difficult question arises-if life and its fiunctions and powers arise from the mere organization of inanimate matter, can consciousness, knowledge and thought be mere results of any combination or organization of the elements of matter, not having in them the inherent properties and powers of intelligence? Is it not absurd to suppose that the mere chemical or physical action of elements of matter, not having in any of them the inherent properties of intelligence, can secrete or produce conception or consciousness, knowledge or thought? 90 VITALISM, SPIRITUALISM, AND Views of Dr. Henry Afaudsley, of London. In his article on the Theory of Vitality, Dr. Maudsley says: " The direct denial of a special vital force has been the natural reaction against that dogmatism which assumed a vital principle that was self-generafing, did anything it liked, and was not amenable to investigation. That any force should be self-generating in inexhaustible quantity, is really an inconceiveable supposition." Comments. Dr. Maudsley entirely misconceives the rational theory of a vital element. No intelligent, clear-headed thinker ever conceived that any power except a Supreme intelligent Being, could generate the elements of matter, or increase the quantity of matter or spirit in existence. The true theory of a vital element does not assume, nor imply that it is a selfagenerating element, principle or force; for such an assumption would be truly absurd; but it does assume, that there is, in the material world, an imponderable element of matter, known to man only by its effects; that it may be in some respects similar to caloric, but much less mobile and abundant-having its own peculiar properties, by which it acts as an organizing agent; and by reason of its limited quantity and gentle action, is not perceptible to the senses, as caloric is. Its existence must be determined, like that of intellect, by human reason, from its effects. Again, Dr. Maudsley says: "An effect need not at all resemble in properties its cause. The qualities of a chemical compound are quite different from those of its constituents. Such a complex compound as organic matter really is, may be expected, therefore, to exhibit peculiar properties, in no way resembling those of its constituent elements, or those of'simple compounds." Comments. The proposition of Dr. Maudsley is an assump MATERIALISM COMPARED. 91 tion which seems to me without any foundation in truth. Is it not impossible in the nature of things, for a combination of various elements to have properties and powers not possessed by any of them-rbut different from all of them? The chemical elements formning the substance of animal and vegetable organisms, are ponderable, and constantly gravitating towards the earth. If there be no vital organizing principle, what is it that resists the power of gravitation, carries the sap upwards in plants and trees, an d carries the blood upwards, as well as horizonttally and downwards, in living animals? In his third lecture on body and mind, Dr. Maudsley says: " I know not why the power which created matter and its properties should be thought notto have endowed it with the functions, of reason, feeling and will-seeing that whether we discover it to be so endowed or not, the mystery is equally incomprehensible to us, equally simple and easy to the Power which created matter and its properties." In his article on the limits of Philosophical Inquiry, Dr. Matudsley says: "The spiritualist may deny God the power to make matter think-but the materialist need not deny the existence of God, because he holds that matter may be capable of thought. Multitudes may logically believe that mind is inselerab!e from body, in life or death —that it is born with it, grows, ripens, decays, and dies with it-without disbelieving in a great and inteligent Power, who has called man into being, and ordained the greater light to rule the day, and the lesser light to rule the night." Comments. Sulch are the confused, inconsistent, and conflicting views of one of the most distinguished materialists of the age. If it be impossible for the mind of,nan to exist as a spirit, separate from the body-it seems to follow that it is equally impossible for a Supreme Being to exist as a Spirit, and without a material organization-and mi terialism sinks to pure atheism. Again Dr. Maudsley says: 92 VITALISM, SPIRITUALISM, AND "In the assertion that mind is altogether a fuinction of matter, there is no more irreverence than in asserting that matter is the realization of mind; * * * To those who cannot conceive that any organization of matter, however complex, should be capable of such exalltedtunctions as those called mental, is it really more conceiveable that any organization of matter can be the mechanical instrument of the complex manifestations of an immaterial mind? Is it not as easy for an omnipitent power to endow matter with mental functions, as it is to create an immaterialentity, capable of accomplishing them through matter?" Comments. Such are the straits to which that class of materialists are driven, who wish to have it understood that they do not deny the existence of a Supreme Being. They find it impossible to account for the mental functions of inan,without either admitting that there is an intelitgent spiritual substance, mysteriously blended with the nerve centres of the brain, or, assuming that God has endowed gross matter with mental functions; and to avoid admitting the former, they assume the latter. The finctions of mind comprise sensation and feeling, perception and consciousness, understanding and judgment, reflection and thought. Does the learned Dr. Maudsley mean to affirm that the elements of matter of which animal as well as human bodies are formed, are endowed with properties and qualities capable of producing mental functions? If so, as plants and animals are formed of the same material elements as man, all living plants and trees must have sensation and feeling, and some, if not all, the ordinary mental functions of animals-which no rational man can suppose. Matter is often at rest. All the action of' matter arises from what we term the affinities of one element for other elements of the material world-or from the tendencies of gravitation-which is only another name for the same thing. But much of the action of mind arises from a tendency to action; some of it arises from its knowledge-some from a spirit of inquiry, to MATERIALISM COMPARED. 93 search after information; and some from mental passions, of various kinds. These are causes of action entirely different from those that move inanimate matter. Even the power of the Supreme Being must be limited by what we may term the logical rules of consistency. God cannot make an incongruous system, having parts inconsistent with each other, work harmoniously; and hence it would be impossible for the Deity to endow the same elements of matter with chemical affinities, and the attraction of gravitation, and also with the inconsistent properties and powers which produce living organisms, and mental action, and make them work together. To endow different elements of matter and spirit with different properties and powers-giving to each properties to adapt it to fill a place, ana cooperate with other elements in producing certain action, seems to have been the policy and method adopted by the Deity to accomplish his purposes. We have a great variety of elements of matter, of which chemists enume'ate over sixty that are ponderable —beside caloric and electricity that are imponderable; to which may be added the vital elemnent, and an intelligent -substance we call spirit — which is the basis of mind and the mental functions — each of which large number of distinct substances has properties and powers peculiar to itself-that adapt it to cooperate with other substances, in producing the various phenomena of the vegetable and animal creations-and of the natural and spiritual worlds. The position of Dr. Maudsly is, that intellect and all its powers and faculties, are functions of matter in an organized state; that God has endowed the matter know.n to the chemist, of which the human body is composed, with the functions of intellect; and that such functions accompany organization-at the same time, he virtually admits, that it is impossible to conceive how matter can have the functions of intellect, unless God has "endowed it with the functions of reason,feeling and will." Considering the fact that 94 VITALISM, SPIRITUALISM, ETC. the phenomena of nature are produced by the action and cooperation of more than sixty distinct elements of matter, each having properties and powers peculiar to itself, and that the human body is composed of more than a dozen of those elements, is it not more in accordance with reason, as well as with the analogy -of all God's works, to suppose that he has added to the human brain a distinct spiritual substance or entity, endowed with the functions of perception and knowledge, reason and will, than to suppose that he has added such properties and functions to one.or more ofthe common elements of the material world, known to the chemist? For any one who can form any conceptions of a Supreme Being, it is easy to form pretty clear conceptions of the existence of the human intellect as a spiritual substance, added to, but in some mneasure independent of the brain. His consciousness of the action of hlis own intellect will furnish to him int,~itions and knowledge, that it acts, to some extent, independently of the body, and of the impressions and influences it receives through the senses. But it is impossible for me to conceive the possibility of God's endowing the material elements of this earth,with such incongruous properties, forces, and faculties, as the chemical affinities and universal attraction-perception and knowledge-reason and will-and make them work harmoniously together. One property of an element of matter so constituted, would act counter to another, and neutralize its action, or produce conflict and confusion. Tile same course of reasoning applies to vital action; which conflicts at every step of its process, with both chemical action and gravitation. It is impossible to conceive how the same elements of matter which are endowed with, and governed by chemical affinities and the attraction of gravitation, can perform the conflicting functions of vital action: and it is equally difficult to conceive, how the vital functions could be performed by such elements as caloric, or electricitywhich have certain affinities of a peculiar kind, but no VITALISM, SPIRITUALISM, ETC. 95 such steady affinities and constant and gentle action, as are necessary to produce and maintain animal and vegetable organisms-which are adapted to act as stimulants and disentegrating forces, but not as organizing agents. Some admit that there is a vital principle or element in nature, who deny the existence of ah intellectual principle; while most materialists deny both. Organization and organs are.manifestations and instruments-not the causes of life and intellect. The action of the living principle forms ant supports the organs of life; and the action of the mind tends to develop and enlarge the brain, and to increase its convolutions. The elements of life and intellect precede: organization and living organs, as well as accompany them. The manifestations and functions of the former are not mere results and effects of the latter-as is erroneously assuimed by the Maudsley school of materialists. Such are my conclusions, which are submitted to the consideration of inquirers after truth. CHAPTER X..CREATION-THE NEBULAR STATE —THE CHEMICAL AND FORMATIVE PROCESSES OF NATURE-SPONTANEOUS GENERATION —AND MAN. Hitherto I have advanced step by step upon pretty firm foundations; and though much of my reasoning is based upon assumed truths and theories, which are the mere inferences and deductions of hum,n reason; yet they are only assumned truths relating to causes of action and effects, that could not be produced without causes —and theories of causes of processes which could not exist without causes and modes of action; and the results and conclusions arrived at, are so completely in harmony with the phenomena of nature; that the whole seems to my mind, like a close approximation to absolute truth. The assumptions have been made; and the theories adopted, to account for hidden causes, where it is absolutely necessary to make some assumptions, and to adopt some theories, as a basis of reasoning, to account for natural phenomena. I have adopted one set of theories, while other reasoners have adopted other sets, in classes of cases where theories of some kind, are indispensable, and it is impossible to reason without them. But to look back and attempt to speculate in relation to the condition of the Universe in the early stages of creation,and to inquire into the formative process of our solar system, and of the earth and its crust, the inquirer, previous to the development of chemical and geological science, had very slender materials, upon which to form a hypothesisand all his inquiries and reasoning were like groping in utter darkness. To prosecute such inquiries at the present day, THE CREATION. 97 with the aid of the light thrown upon the subject by Chemistry and Geology, natural history and physics, is like groping in twilight. We have now much light and knowledge upon which to form theories of the formative processes of creation and nature; but our knowledge is too limited and imperfect to form them and to reason with much assurance of accuracy, or even approximation to accuracy; and yet the human mind, thirsting after knowledge, is not satisfied without making efforts to inquire into such subjects. For many centuries, and until a comparatively recent period, the whole christian world believed in the literal interpretation of the account of creation, contained in the book of Genesis-that God created the heavens and the earth, by a mere fiat of his will, and called the sun into existence by simply declaring, Let there be light. (when the sun came instantaneously into existence,) and there was light. Very few educated, intelligent christians, at this day, believe in a literal interpretation of the Scriptural account of the creation, in six days. We do not know, and cannot know, the extent of God's power, nor the mode in which he exercises his creative and conservative powers; and we would not presume to assign limits to his power; but whatever may be his power, to call into existence instantaneously, vast systems of worlds in perfect form and working order, fitted for action, like our solar systcm, and fitted for the abode of animals and intelligent beings, like man, it is very certain that he has not done so. On the contrary, all the facts of geology and natural history attest, that after a crust was form-'ed over the surface of the earth, the formative process was going on for ages and thousands of years, before it was fitted for land animals, or animals of any kind, bzt fish and marine animals; and that still farther ages and thousands of years elapsed, before the earth and its atmosphere were fitted for the production of grasses and grains, and for the abode of mammals and other warm bloooded animals, and man. 7 98 THE CREATION. Whatever power the Divine Mind may have to call things into existence by the fiat of his will, it is very certain that he does not usually exercise such power; unless it be by the creation of simple elements of matter, and their appropriate properties and forces. It is equally certain that he acts mostly by and through the agency of the forces of nature,.as secondary causes and means of developing gradually, and perfecting the universe and the crust of our earth and its atmosphere, and fitting them for the support of animal and vegetable life, and of man. Some have supposed that at an early period in the history of creation, the elements of matter now composing the universe, were diffused through space, in an attenuated, confused, and unformed state —like nebulae; and hence the formation of a theory of creation, known as the nebular theory. That is all speculative, in some measure uncertain, and beyond the domain of human knowledge; and yet there is reason to believe, that the matter forming our solar system and the universe, was once greatly dispersed and diffused through space, in a chaotic, uncombined, and unformed state; that the sun and the earth, the planets and other heavenly bodies, each and all occupied five or ten, and perhaps an hundred times as much space as they do at the present day; that not only the sun, but also the earth and the planets, were destitute of any crust on their surface, and had no solid parts-that even water was not yet formed, and atmospheric air, in its present state of purity and separation fiom other elements of matter, did not exist. The elements were diffused through each other in a state of chaos-or such was probably the condition of the universe. The action of caloric, electricity, and the force of universal attraction, gave the elements of matter,when in their original gaseous state, a tendency to action,and the Divine Mind probably gave direction to their action, and gave them a circular motion-all in nearly the same - direction-to harmonize their movementsand produce systems of worlds, moving harmoniously THE CREATION. 9p in the regions of space. When nuclei were once formed as centres of motion, one large central nucleus and numerous smaller ones around it, the tendency was to move in circles around the great central orb, which was the centre of attraction, each attracting and drawing to itself the particles and small collections of atoms which came within its influence; and thus they increased in size and influence, and became suns and planets, or satelites-the two latter classes gradually becoming regular in their movements around the former, as their central sun-and each and all becoming more and more compact, by means of their motion on their axes, and the formative action of universal attraction and the chemical affinities,whereby a crust was gradually formed upon the surface of the earth,and upon many of the planets also, as is believed by. astronomers. There is not caloric in our solar system sufficient to produce much heat, while the earth, sun, and planets, or the elements of matter now composing them, were in a gaseous or very attenuated condition, diffused through five, ten, or twenty times as much space as they now occupy. The nuclei which eventually formed the earth and planets, must have been at first in their attenuated condition, very cold-too cold for chemical affinities to act with much force, if at all. Chemical action, and chemical combinations, will not go on, when either the excess or the deficiency of caloric is very great; when matter is in a fluid or gaseous state from excess of heat, or in a congealed state from an almost entire want of caloric. But as the globe became more and more compact, and the caloric which it contained was collected within a smaller compass, it became warmer, the chemical affinities acted with more force, and formed the chemical combinations constituting acids and oxyds, salts and metallic ores, earths and rocks, which form the crust of the earth, and also water. As nitrogen is one of the lightest elements of the material world, and enters into very few chemical combinationsother than animal and vegetable organisms, it 100 THE CREATION. was carried to and left to float upon the surface of the earth-forming over three-fourths of the atmosphere. Oxygen is the most abundant element in nature. It enters into more chemical combinations than any other substance, and after combining with all the metals and bases of earths, in such proportions as its omniverous affinities required, and combining with and swallowing up,in forming water,all the hydrogen which came within its influence, the surplus remaining — being lighter than any of its compounds, very naturally rose to the surface of the earth,and floated upon fhe surface, in a state of mixture with nitrogen and carbonic acid gas, forming the atmosphere. Carbon also, being lighter than most other substances, floated on the surface of the earth, combined with such proportion of oxygen as would unite with it —forming carbonic acid gas-which vitiated the atmosphere, and rendered it unfit for the respiration of man, or the higher order of animals, but extremely well adapted to produce and support a luxurious vegetation. The quantity of carbon, however, being comparatively small, it was eventually mostly absorbed and appropriated by vegetable organisms. When the chemical and formative processes of nature had proceeded so far as to contract the nucleus forming the earth to nearly its present size, to form a firm crust of earth and rocks over its surtace, and to form large bodies of water covering the most of it, and an atmosphere was collected around it, it was fitted for the reception of both animal and vegetable life, of the coarser forms; but the atmosphere at first contained great quantities of carbonic acid gasquite too much to be fit for the respiration of man or any of the higher orders of animals —until the development of vegetation, knd the growth of vast forests, had consumed the excess of carbonic acid gas, and thus purified the atmosphere. The crust of the earth must have been at first thin — only a few hundred feet thick; chemical action was going on in the interior, new chemical compounds THE EARTH S CRUST. IO1 were forming, and the formative processes of nature were going on, solidifying the gases andfliquid matter, immediately under the crust of the earth, and increasing its thickness. As the formative process went on, and the gases under the earth's crust were gradually from age to age, formed into fluids, and converted into salts and metallic ores, earths and rocks, and the crust of the earth increased in thickness, the chemical compounds of earth and other substances, occupied less space than the gases out of which they were formed, and left something like a vacuum immediately under the crust; some portion of the crust settled down, and fell in, from time to time, leaving other, more solid portions, in their former places; whereby hills and mountains, plains an i valleys, were formed, and also great gorges and gulfs, into which the waters settled-forming permanent oceans; and by draining off the waters from large districts of territory, extensive plains, and gently undulating countries were also formed. Before the formation of the earth's crust, water was formed and floatedin the gases near the surface of the globe, in the attenuated form of clouds and vapors, but not in the condensed form of a fluid. Watercould not exist in the condensed form of a fluid,until a crust of earth was4formed upon the surface of the globe,to sustain it; and large bodies of water could not exist, until the earth's crust had attained a considerable degree of thickness and strength. The subsidences, upheavals, and breaking up of the earth's crust. When the earth's crust was so thin that the weight of the water accumulated upon it, occasionally broke through where it was the thinest, and the water deepest and heaviest, the water must have poured into the breach in enormous quantities-and coming into contact with the igneous mass of earths and metals in a fluid state, it was suddenly converted into steam, and I02 THE EARTH'S CRUST. so expanded as to produce a terrible and wide-spread convulsion and upheaval of the crust, raising up large portions of the surface of the earth, and breaking up millions of square miles of the crust. As the igneous mass thrown to the surface cooled down into rocks and earths, and the steam was condensed again into water, the broken fragments of rock gradually settled down with the earth and mud into the water, and filled the breaches in the crust. Such a volume of water flowing throagh the crust of the earth when a breach was made in it,and coming into contact with the igneous mass of earth and metalic bases of the interior of the globe, would absorb a prodigious amount of caloric before it could be converted into steam. The process would cool the igneous mass to a considerable depth, harden it, and it would be added to the interior of the earth's crust, and form a part of the crust; and the melted matter thrown out by the convulsion would cool upon the surface, and add to the external side of the crust-whereby the crust of the earth would be thickened on both its external and internal sides. The first effect of every such convulsion was, to raise large districts of country into mountain ridges and lofty peaks, high hills and elevated table-lands-to elevate adjacent districts into plains gradually sloping towards the sea-and to sink other districts and the bottom of the sea, to levels much lower than they formerly occupied; but eventually the whole settled down to lower levels than they occupied before the convulsion, and the diameter and dimensions of the globe were permanently contracted. As the chemical combinations and formative processes of nature went on, and the interior of the earth next to its crust gradually shrunk in dimensions, geology furnishes abundant evidence that the crust cracked and broke, and settled down in large districts, and the diameter of the earth contracted, at several different periods-sinking the ocean at each subsidence to greater depths, leaving the mountains at greater elevations THE EARTH'S CRUST. I03 above the sea, and making greater and greater inequalities in the earth's surface. The new chemical combinations constantly pressed out from between the atoms of matter forming the gases, and evolved caloric, and increased the concentration of caloric in the interior of the earth, in the immediate vicinity of such chemical combinationsso that the interior of the earth grew hotter as it contracted in size, front the time the first thin crust was formed on its surface, until the whole mass was converted from a gaseous to a fluid state, and the elements were all formed into such states of combination, that no extensive new chemical combinations were, or could he formed. The earth then ceased to contract any more, and assumed a constant temperature, and a settled and permanent condition, nearly stationary — though interrupted occasionally by earthquakes-by the sea breaking through some weak and defective place in the earth's crust, or through some fault or crevice in the rocks, the water coming into contact with the igneous melted matter of the interior —being expanded and converted into steam-and producing great convulsions of the crust of the earth. The earth's crust was at first thinly spread over the accumulated gases of the interior. Perhaps the first formation of a crust may have been only a few hundred feet thick; and as the processes of chemcal combination and formation of earths and rocks were going on immediately under the crust, and pressing out from the gases, and setting free the greater part of the caloric held by them; and as the sun's power of attraction was operating by day, and constantly operating upon one side or the other of the earth, drawing caloric from the interior to the surface and into the atmospere, the temperature at the surface of the earth must have been very great-very much higher than the temperature of the torrid zone at the present day: and hence the production of the monstrous animals of both sea and land —and the production also of the immense amount of vegetation, and the vast forests of 104 THE EARTH S CRUST. wood and timber, which were subsequently formed into the coal fields of the earth. When, by means of chemical action, a vast amount of the gases of the interior were converted into liquid igneous matter, earth and rock, the gases became more rarefied and something approximating to a vacuum was formed, the great weight of the crust, and of the waters and atmosphere, pressing upon it, eventually settled it down, cracked it, and broke it up in many places, and the immense trees and forests growing upon its surface, sank down into the liquid fire, were charred, partially tburned, mixed with sulphur, hydrogen, and earthy matters, and converted into beds of fossil coal, for the present and future use of man. The process of settling down and breaking up the crust of the earth was performed several timesas is shown by the numerous layers of coal, and fossil remains of shell fish and extinct animals, one above another, in many places; and at each great convulsion the great bodies of water forming the oceans and seas, sank deeper and deeper into the bowels of the earth,the waters were drained off from large districts of the earth's surface, leaving extensive plains, hills, and valleys above the sea,, which had been previously covered; and leaving the mountains at still higher elevations above the ocean. Each of the great convulsions, when the earth's crust was broken up over a large portion of its surface, formed an era in geological history; and the time which elapsed between each two of those eras, constitutes what is known as a geological period. The temperature of the earth's surface grew cooler and cooler, at each succssive period, as its crust grew thicker, and the surface and atmosphere were farther removed from the liquid fire of the interior. Eventually the gases of the interior were all formed into chemical combinations, and into solids and liquids, or at least all those near the crust of the earth were so formed, and the crust became sufficiently thick THE EARTH'S CRUST. I05 and strong to support the incumbent weight of oceans several miles in depth, and of ranges of mountains many miles in height; the temperature of the earth's surface became constant, and nearly the same at the same seasons of the year; and~the surface of the earth and its atmosphere was fitted for'the abode of the higher grades of animals-of mammals, and of man. When the crust of the earth was first formed, its surface was probably nearly level, and at nearly equal distances from the centre of the globe-presenting no..such inequalities of mountains, plains, and valleys, as now exist. For the purposes of illustration,let us suppose that as chemical combinations, and the solidifying processes of nature went on, and the earth s crust was thickened from the under side, vacuums, or large spaces of more attenuated gases, must have been made immediately under the crust-by reason of which the crust, pressed by oceans of water above it, settled down at various times, and crevices were formed —through' which the sea flowed in,and the conversion of the Water into steam, caused great convulsions and upheavals, after each of which the whole crust of the earth settled down again, filled up the vacuums below,and then became quiet; and that all the shrinkage of the globe and the settlings of its crust from the first formation of a'crust until the present time, has been equal to ten miles on each side — whereby its diameter has been diminished twenty miles —as the highest peaks of the Himalaya mountains are only about five and a half miles above the level of the sea-if my supposition be correct, those peaks have actually settled down below their original places upon the earth's crust, about four and ahalf miles; other mountains have settled from five to nine miles and upwards; the level of the sea has settled ten miles; and the bottom of the sea has settled from ten and a half to perhaps twenty miles. As the beds of the oceans and the softer parts of the earth's crust must have settled more at each subsidence and convulsion than the' more solid rocky por Io06 THE EARTH'S CRUST. tions, forming the mountains, the subsidence of the ocean at each of several great convulsions, left millions of square miles of dry land, which had been previously covered by the sea. The valleys of rivers and of mountain streams, as Wvell as those across plains, were first formed by the running off of the waters at the subsidence of the sea, after great convulsions had taken place; but the valleys as well as the beds of the streams, have been gradually worn down by the running off of the waters which have fallen upon the earth in rains and snows, during thousands of years. The gorges through ranges of mountains commenced in faults, fissures, or crevices of the rocks, or at the time of great convulsions-before the rocks had settled down into a compact and solid state, and when there were crevices or comparatively soft earthy matter in them, through which the water penetrated, wpre away the earth or soft rock, and gradually formed for itself a channel. When the rocks were sufficiently compact and solid to withstand the influence of the water, they dammed it up, and formed lakes or inland seas. Seams or veins of metallic ores and of quartz rock, volcanoes, and earthquakes. The seams or veins of metallic ores of various kinds, and of quartz rock, from one-fourth of an inch to several feet in width, which are found in feldspar and other rocks, were probably nijected in a liquid form, from below, through crevices in the rocks, opened by great convulsions of the earth-by reason of the breaking through of some portion of the bottom of the ocean, immense quantities of water flowing in, and its sudden conversion into steam. We know of no power in nature, other than steam, which could produce such results. Volcanic eruptions are mostly confined to pouring forth melted lava, ashes, and cinders; and never produce any such eflects. Earthquakes usually occur near the sea or great rivers, and there is reason THE EARTH'S CRUST. I07 to believe that they are caused by the expansive power of steam-by water running through crevices in rocks, and coming into contact with such a degree of heat, that it is converted into steam. The action of the Geysers, of the valley of the Yellow Stone, and other countries, which throw hot water high into the air, is probably caused by the power of steam, formed in the interior of the earth, by water coming into contact with igneous matter of some kind. Prof. Dana's account of volcanoes, in his Manual of Geology, makes the whole number in the islands and on the continents of the earth, about four hundred -but their action is- very generally quite harmless, when compared with that of earthquakes. They have produced no great changes in the condition of the earth. The action of volcanoes, as well as that of earthquakes, probably arises from the expansive power of steam-the former operating in most cases slowly and moderately, because confined within a narrow sphere, when compared with the latter-which generally produce their shocks quickly and violently, and often act along a long line, hundreds of miles in extent. Earthquakes act much like the explosive compounds of gunpowder, and gun-cotton. Atmospheric vapors and clouds are always filled with electricity-which produces thunder, when accompanied with wind, and sufficient caloric-but not otherwise. It seldom thunders in cold weather. There is no reason to doubt that steam contains as much caloric as atmospheric vapor does, when the latter is the most intensely heated. Hence we may reasonably conclude, that caloric and electricity constitute the active forces of steam, and also of gunpowder, and guncotton. The elements forming water, and such compounds as gunpowder and gun-cotton, have no such forces or power until ignited, and permeated by caloric or electricity, which seems to be always accompanied by caloric. Io8 PIKE'S PEAK. JpheavaZs at and near Pike's Peak. Pike's Peak and the vicinity, and many other places in the Rocky Mountains, furnish evidences of the sudden upheaval and breaking up of the crust of the earth. The top of Pike's Peak is elevated more than 14,ooo feet above the level of the sea, and more than 8,ooo feet above the edge of the great plain at the foot of the mountain, ten miles distant. The upper 3,000 feet is very steep, and there are but few places where it is practicable for even healthy and vigorous persons to toil up its steep ascents, and climb over the fragments of rock which have crumbled off from its rim, and fallen down upon its sides. In several places the gorges in its sides are nearly perpendicular from the top down, a distance of perhaps 2,000 feet or more. The top presents a surface nearly level, but slightly crowning in the centre, comprising an area of 60 to 80 acres, covered with fragments of a reddish granite, weighing from an ounce to several tons, with scarcely a square foot of sand, gravel, or earth of any kind. The rocks and stones have straight sides, slablike, and square or sharp corners-presenting the appearance of having been broken up by some great and sudden convulsion, and showing no signs of having been water worn-having no such rounded sides and edges as the water worn boulders and stones of the beds of streams, plains, and valleys, usually have. The gorges in the sides indicate that the whole Peak (with the exception of the broken fragments upon the top and sides),consists of one vast solid mass of granite, for thousands of feet in deptli. The air of the upper part of the mountain is so attenuated and light, and the ascent so steep and laborious, that it tries to the utmost the lungs and the brain, as well as the heart and the muscle. None but well and strong persons should make the attempt to ascend to the top, in the present condition of the mountain; without even a foot-path,near the top. The time will come when a mule path, and also a carriage road will be made to PIKE S PEAK. IO9 the top, and thousands of persons will then ascend the Peak, every summer. I stood upon the top about an hour, in mid-day, on the I3th of September, I872, when the sun was shining brightly, and the air was clear and pure-had a view of the main ridge of the Rocky Mountains, with its snow capped peaks, from Long's Peak, to the peaks of Northern New Mexico — a distance of more than zoo miles-and looked down upon the great plains at the foot of the mountains upon the one side, and upon the famous South Park upon the other. There were in view more than fifty peaks, of less magnitude and elevation, raised from 8,ooo to I2,000 feet above the level of the ocean, and from I,ooo to 6,o000 feet above the adjacent plains, valleys, and gorges of the mountains. The view was one of the grandest and most extensive which the eye of man ever beheld. The great gorge upon the eastern side of the Peak was filled with snow, but there was no snow upon the top. The eastern side of the mountain, where I ascended, several miles from the top, is, in some places, covered with boulders, many of them of enormous size, which would weigh hundreds of tons, and some perhaps thousands of tons; and in one place there is a large bridge of rock over a ravine and brook. Though the atmosphere and frosts, rains and snows, during ages and thousands of years, have produced some impression upon the surface of the rocks, they present no appearance of being water worn; and it is difficult to conceive, how such a Peak, and the boulders upon its top and sides, could have been formed, except by a. great convulsion, which raised suddenly andl broke up the earth's crust, and raised the igneous rocks which form the Peak and its sides and boulders, and broke them in pieces; and when the waters had washed away the loose earth, sand, and gravel, that was raised with them, they assumed very nearly the appearance and condition which they now present. Time and the elements gradually produced some disintegration of the softer parts of the surface of the rocks, and con I I10 GARDEN OF THE GODS. verted them into soil, upon which grass and trees have grown, covering in many places the sides of the mountain, to an elevation of about Io,ooo feet above the ocean-but they have produced very little effect upon the top of the Peak. Upon the sides of a gorge in one of the foot-hills of the mountain, between the celebrated Colorado soda springs, and the place known as the Garden of the Gods, there are visible more than fifty alternate layers of red sandstone, and feldspar and soda rock, generally from one to two feet each in thickness, lying one above another-having a pitch of not more than 15 or 20o degreys. The place called the Garden of the Gods is situated on the plain, near the foot of the mountain-the top of which bears the name of Pike's Peak. It presents to the view several large rocks, seeming to stand up on their edges, rising out of the plain from ioo to 200 feet or more in height, and from one hundred to several hundred feet in length-with a breadth of from 50 to perhaps xoo feet. Some of them are composed of sandstone, and some of clay and soda rock. The tops in some places present such fantastic forms, that, looking at them from a short distance, it requires no great.stretch of the imagination to see in them the forms of animals and angels, Gods or demons-and hence the place derived its name. In the Garden of the Gods, at Glen Eyrie near it, and along the plain near the foot of the mountains within twenty miles north of it, there are numerous columnar and other rocks-rising perpendicularly above the plain to considerable heights, and presenting to a distant view, appearances very similar to the ruins of ancient temples, castles, and fortifications. There is upon the ridge of a foot-hill, near the Garden of the Gods, a long line of rocks, standing up perpendicularly like slabs or combs above the earth, on each side of them. There are also upon the tops of two parallel foot-hills, a few miles north-easterly from Golden, and about 15 to 20 miles north-westerly from Denver, CLEAR CREEK CANYON. I X I two similar parallel lines of rock, standing up perpendicularly, and forming the culminating points of each of the ridges, as they slope down from the mountain to the plain. The two parallel lines of rocks upon each ridge,look, in the distance from the railroad, very much like the parallel rails of a railway-except that they appear farther apart. When we inquire into the causes which produced such rocks and phenomena, they appear truly wonderful, as well as curious. What other than a sudden upheaval and breaking up of the earth's crust, could have set such rocks up on their edges, and raised or formed such an immense mass of rock as Pike's Peak? Does nature possess any power but steam, which could produce such wonderful effects? The great gorge or canyon of Clear Creek, in Colorado Territory, where it cuts through the eastern ridge of the Rocky Mountains, is one of the wonders of the world-exceeded only by the famous Yosemite valley, the valley of the Tuolumne river, in the State of California, and some portions, perhaps, of the great Colorado river. Clear creek has cut through the rocks, very generally a thousand feet or more in depth, and formed a channel only just wide enough for the stream -often leaving not space enough at the foot of the rocks, on either side, for a mule path. The bed for the narrow gauge railroad, which has been recently made through it, was formed much of the way, for about ten miles, by blasting the solid rocks at the side of the stream-leaving many points of rock hanging over the road. Numerous veins of quartz rock, often from two to five feet in width, are presented to the view of the traveller; and every mile of the way presents-evidences of the upheaval and breaking up of the-carth's crust, at some remote period of the world's history.- The canyon and its surroundings present wonderful views for the study of the geologist and the physicist —-to speculate upon and inquire, how and when such wonderful effects and scenery were produced? I 12 SPONTANEOUS COMBUSTION. Spontaneous action of matter, and spontaneous combustion. Chemical action is caused by the affinities of two or more elements of matter coming in contact, or within the reach of each other's influence-when they unite and form a compound. Chemical action is properly called spontaneous action-because it is produced by the properties and natural affinities for each other, of certain elements of matter-acting without external influences, or artificial means. Chemical action, by forming new combinations of elements of matter, generally develops and sets free considerable quantities of caloric, which often produces combustion, when it comes in contact with combustible materials which are extremely volatile, or very dry. Combustion produced by chemical action without friction or the application of fire, is called spontaneous combustion. When water is poured upon unslacked lime, it is rapidly absorbed by the lime, which causes violent chemical action, developing steam and caloric in such quantities as to ignite combustible materials in contact with the lime, or very near it. This is one of the most familiar ctses of spontaneous combustion. Cloths, and particularly cotton cloths, saturated with oil and turpentine, paints and varnish, sometimes produce such chemical action as to cause spontaneous combustion, and burn paint shops and other buildings. The waste and fine particles of cotton, tow, and wool, in cotton, linen, andcwoolen factories, sometimes become so saturated with oil, that after lying some time in heaps, chemical action takes place, and causes spontaneous combustion. Many buildings have been burned very mysteriously, when the fire could not be accounted for upon any principle but that of spontaneous combustion. Bituminous coal, lying in heaps, is sometimes ignited by the caloric, developed by the decomposition of SPONTANEOUS GENERATION. I 13 the sulphuret of iron contained in the coal. Other classes of cases are stated in the new American Cyclopedia, title-Combustion-Spontaneous, in volume V, to which the attention of the reader is invited. Fermentation is a term applied to spontaneous changes which take place in the remains of animal and vegetable organisms, when decomposition begins. It is a calorific and chemical process, caused by caloric and the action of the chemical affinities to form new combinations, after caloric has commenced disintegrating and decomposing the organism. Caloric acts like the yeast of the baker, and the ferment of the brewer, to commence the process, before chemical action begins. It is impossible to make vinegar without both heat and ai:'. But put sweet cider or wine into a cask or bottle, cork it up tight and make it impervious to air, and put it in a cold place, and it will keep sweet any length of time; but keep it where it is warm, and the action of caloric will cause it to expand, and throw out the cork, or burst the cask or bottle. Such cases show the agency of caloric in fermentation. In discussing the causes and the process of fermentation as well as combustion, chemists have very generally overlooked the agency of caloric-and hence they have been puzzled to account satisfactorily, for the causes of those processes-and hence the differences of opinion, and the various theories upon the subject. Spontaneous generation, and the spontaneous production of vegetation My observations, and my reading and study of the experiments and reasoning of others, as well as my own reasoning upon the subject, all lead to the conclusion, that the vital principal in animals, and in vegetable organisms, is an organizing element of nature, -pervading the crust of the earth and the atmosphere, as caloric and electricity do; and that it constitutes 8 I 14 PROF. LEWIS' VIEWS. the seed, and nucleus of the germ, from which all animal and vegetable organisms have originated, by means of its organizing power, cooperating with other elements of nature, and with the more direct agency of God, in giving such direction to its action as to form types-and in superadding to the physical organisms of man and the higher orders of animals, an intellgent principle, adapted to their condition, wants, and destiny. It may be said, and objected to this view of the case, that it accords with the theory of spontaneous generation. But is that a sound objection? We have the spontaneous action of caloric and electricity-spontaneous chemical action-spontaneous combustionspoutaneous fermentation-spontaneous decomposition of rocks and mineral compounds, as well as of animal and vegetable substances, and the spontaneous formation ot rocks and crystals, and of various earthy and mineral compounds-and why not the spontaneous generation of animals, and the spontaneous production of plants? The following extracts from chapters XVI, XVII, and XVIII, of a work on " The Six Days of Creation," by Prof. Tayler Lewis, of Union College, New York, present the subject fairly, and throw much light upon it. Prof. Lewis says:* "Geology finds very ancient vegetable and animal remains, but gives us no light whatever on the questions, whence they came, or how they commenced the origin of their existence." He quotes Ist Genesis, IIth and I2th: " And God said, Let the earth bring forth grass, the herb yielding seed after its kind, and the fruit tree yielding fruit whose seed is in itself, after its kind, and it was so. And the earth brought forth," etc. Here (he says) are two distinct things-the going forth of the Divine Omnific Word, as in the other creative periods, and the productive power, energy, or energizing of the earth. * * * The earth then was not a mere passive recipient, nor was production by it a mere outward, unessential mode, having no other than an arbitrary connection with the Di*Prof. Lewis is a Christian gentleman, who has a high order of reasoning powers, and a high reputation as a Greek scholar, and a man of learning.

I I5 vine working, or employed merely as an accompanying sign; but the earth exerts a real causative power, and this becomes an essential and important part in the chain of causation which God saw fit to originate and establish. The Divine power was exerted, but it was upon the earth and through the earth. It was upon the nature, and through the nature,that had become established in the previous creative acts; whilst, at the same time, there is the beginning of a new energy, imparted to this nature, which it did not possess before. The command is to the earth.; but the earth is not passive. She exerts an active obedience in the exercise of the old nature, modified by the new force, which comes from the supernatural Omnific Word, going forth, as it previously did, for the separation of the light from the chaos, and the waters from the waters. Before, it was' Let there be light,'-and now again Let there be life -and life began to be. As in all the other periods, so here, there was doubtless the instantaneous beginning of a new, and at first, supernatural f)rce, put into nature." " The only idea we have of nature is that of a regular, constant flow of cause and effect, governed by established laws, operating uniformly, or ever in the same manner, under the same circumstances, and with the same accompaniments. * * * From the necessity of our laws of thinking, as well as from revelation, we say that it is a power given originally by God. But, though thus originated, we can distinctly conceive of it as a nature only when we regard it as in some manner left to itself, and operating by its own laws and methods. * * * We may suppose this original Divinforce ever present as the supporting ground, but not im-manent or per-manent as the immediate causal force in every natural effect. God is able to impart such a natural power, and leave it in this sense to itself-thus making it something different from the immediate Divine energy. Those who hold with Malbranch and others, that there is ever the im-manent Divine plresence in every act of nature, do, in fact, diminish, instead of magnifying the Divine power and dignity. It is simply maintaining that God cannot make a nature, and hence, of course, that there is nothing supernatural, because, in fact, there is nothing truly natural. It is unmeaning, too, and absurd; since it supposes media, which are, in truth, no media, but only arbitrary signs-having no dynamical connection with the effects. Nature, in this view, would be as irrational as a machinery having all the appearance of mediate dynamical causation, and yet requiring the constant application of the original motive force directly to every wheel, and cog, and strap, in the complicated structure."'Holding nature thus to be,,in some sense,a self-subsisting, self-acting power, we may next regard it in its extent and degree. It may be the universal nature, that is the whole na I I6 PROF. LEWIS' VIEWS. ture of the universe, in all its connected and independent organization, as one great force-developing itself, by laws which God has given it. Or it may be a partial nature, such, for example, as the nature of the earth, or of some still less organism, such as-that of a tree, or an animal, developing itself, by its own internal law, as modified by its connection with the universal. * * * Every nature, whether of the whole or a part, whether inchoate or advanced, must be finite. There are limits to its working, which it cannot pass; there is a height above which it cannot rise." " In every nature, too, regarded by itself, there must be continuity. The mind demands this, as involved in the very idea of nature." "If any one ask-why does God work in this way? What need has he of natures? We can only say,' So it seemeth good in his sight.' He could, doubtless, have made all things differently-but we know it would not have been the best way, because he has not adopted it. He works through nature, or a succession of natures-no one developing another, yet each preparing the way for the one that is to succeed. We see enough of the universe, to know that this is the method; and thus considered, the general view is unaffected by the measure of duration." " If we thus view nature as a stream of causation-governing by a certain law, which not only regulates but limits its movements, then the supernatural, as its name imports, would be all above nature-in other words, that power of God, which is employed'according to the counsel of his own will, in originating, controlling, limiting, increasing, opposing, or terminating nature, whether it be the universal, or any particular or partial nature. Thus regarded, the supernatural would assume various aspects, to which we may give distinctive names." "' lad we been told that instantly, by the Divine fiat, the earth was covered with vegetation of the largest and most perfect kind, that in a moment there stood forth in all their physical perfection, the creeping hysop, the rose of Sharon, and the waving cedar of Lebanon-that in the twinkling of an eye, from being a barren, inanimate, and solitary waste, our world was swarming with animals of every size and species, full grown, and at the maximum of their strength and beauty, there would have been no a priori difficulty in believing it. There would have been nothing irrational or incredible in the account. Such an instantaneous production would have been in harmony with all our ideas of the Divine power and dignity. But it has not been so revealed. A different method was taken by the Divine Wisdomthe method to which we give the name of nature-the method of PROF. LEWIS' VIEWS. 117 growth, of succession, of duration, of the apparent birth of one thing out of another, and this too, through the action of a previous nature, quickened by a new Word. into a new energy, and to the development of a new law. Both these suppositions, we say, are rational-both are pious-both are credib.e, if clearly revealed." " But there are other hypotheses which are not rational, which are not credible. * * * One is, that the trees and animals were formed directly by the hand of God, and then placed in the earth, that it might bring them forth, or be said to bring them forth, thus perfectly formed. Another is, that by the same direct divine power, they were formed in the earth, but not through any natural agvncy of the earth; the formative act not being a nature, or a growth, but as far as the earth was concerned, outward, mechanical, or magical; the bringing forth being by no natural power acting through any previous or then imparted law. Another is, that the seeds of vegetables were formed perfect by the direct Divine power, and then planted in the earth. But they all have this feature. They present the appearance of a causation, which is not causation. * * * The seed is as much an organism as the plant or tree-far more so than the bark, or branch, or root. It has the same appearance ofgrowth, or of having grown from a ounger state; it suggests the same idea of succession, or natural process. Divine Omnipotence could make them, doubtless; but so, also, it could make the perfect tree or animal. It is liable, therefore, to the same charge of unmeaningness, of inconsistency, of appparent fallacy-of having neither the reason of the supernatural, noro the law of the natural." As to development theories, Prof. Lewis says: " A development theory which has no Divine oriqination, or acknowledges the going forth in time of no Divine TWord, is indeed atheism. * * * But a development theory, in the sense of species from species, as well,as of individual from individual, may be as pious as any other. It may have as many Divine interpositions as any other. It may be regarded as a method of God's working, and that too, as rationally and as reverently as the more limited system to which we give the name of nature, in its ordinary or more limited sense. Modern theologians have been too much frightened by certain assumptions and speculations on this field. * * * It is enough for us to learn, without doing any violence to the language of the (scriptural) account, that the production of the vegetable and animal races are set forth as having been originally a growth -a glowth out of the earth, and by and through the earth-in other words, a nature with its laws, stages, successions, and developments." " There was a previous nature in the earth, whether it had been in operation 24 hours, or 24 thousand years. We IIS PROF. LEWIS' VIEWS. may compare this to a stream flowing on, having its regulai current of law, or regulated succession of cause and effect. Into this stream we may say, there was dropped (by God) a new power, supernatural, yet not contra-natural-varying the old flow, and raising it to a higher law and a higher energy, yet still in harmony with it. New causations, or new modifications of causation arise, and alter the successions and steps required, be they longer or shiorter, a world of veqetation is the result of this chain of causation, in the one period, and through an anldagous, if not similar process, an animal creation arose in another." " The first plants grew, they were made to grow in the earth, and out of the earth. They were born of the earth; they were carried in her womb during their respective periods of gestation; their embryo or fcetal life was fed by her warmth and moisture; and they afterwards were nurtured and grew up, each to its perfection, on her maternal bosom. Ihey grew; and growth is the cardinal idea of the word natu re. " "The same thing, or a similar thing, is said of the animals. And God said-' Let the waters bring forth abundantly the moving creatures that hath life'-Genesis I, 20. This refers to the fish and reptile races, and what would seam more strange, to the birds, which are connected with them in a manner which would appear to imply some community, or similarity of origin. And again -' Let the earth bring forth the living creature after his kind.' This refers to the quadrupeds. and land animals generally." Again the Professor says: "The view here advocated as the right interpretation (of the scriptural account), is very different fiom that eternal and unbroken development which is only another name for the darkest atheism. God's personal sovereignty and personal interposition are as directly recognized as in the most distinct exercise of miraculous powerand that not once (only), or in some far off principium, but in repeated and oft repeated acts. * * * There was an exact moment when animal life began a life which before was not in our earth, and which, but for the Divine Word sayinq, Let it be, most assuredly never would have been. The earth, or nature in her largest sense, through any power previously belonging to them, never would have originated or developed, or brought it (life) into e- istence But still it does say, most distinctly, the earth brought them (the animals) forth, or gave them birth. The prolific waters was the natural bed in which, through the vivif)/ing agency of the Ruah Elohim, or Divine Spirit, originated the first moving things." Again Prof. Lewis says: " The seed itself, as much as the tree, is an outward organization, the apparent product of a living power lying back of it. as a real entity, per se, and, in PROF. LEWIS' VIEWS. I19 fact, better entitled to the seminal name. than the material seminal organization; because it is this living power which builds the outward matter of the seed into its peculiar form and structure-thus constituting its essence-making it what it is. Besides, if we search for this previously existing thing, by going back of the tree to the seed, there is no reason why we should not recede a step farther, to the vitality that dwells in the seed itself, which, in the order of nature, as well as in the order of ideas, is anterior to the material organization." Quoting Hebrews,XI,;3, he says: "The outward or phenomenal entities were generated or born from the invisible, immaterial, vital powers, principles, laws,spermatic words or ideas; call them what we will-which are themselves, the first and immediate creations of the Divine Word, going forth before.any new agency of nature." Again: "' Faith is the evidence of things unseen, for by it we understand that in creation, the things that are seen came out of, or were born of, things that are unseen." Again he says: " The birth of these seminal principles was independent of all natural agency. In this sense, it was before the fertilizing rain, or the assiduous human culture. However progressive and natural the after production from the earth, the creation of these seminal types or principles, was wholly supernatural, immediate, Divine." Such are the views of one of the clearest-headed Christian philosophers of the age. They are worthy of the consideration of the reader. Spontaneous vegetation. In the winter of the year I869, I purchased some green wood, four feet long, which contained a few sticks of basswood; and had it piled in my yard. The following season was a wet one, and one of the split sticks of basswood lying upon the ground, at the bottom of the pile, put forth leaves and a stem the next summer; and a round stick, about four inches in diameter, lying in the middle of the pile, more than two feet from the ground, also put forth leaves and a stem. Each of the stems grew out of the side of the stick, where there was no bud, nor joint, nor limb; and they continued to grow until the latter part of September, when they were from i6 to I8 inches long, and the leaves were killed by frost. 120 SPONTANEOUS VEGETATION. These cases show that the seminal and fructifying power of trees consists of their vitality, which exists in the sap, as well as in the fibre and bark; that when a tree is cut down it often retains some degree of vitality for many months; that in these cases the basswood sticks retained so much vitality, that when they were saturated with rains during the spring and early summer, the moisture and heat so increased the quantity of sap in the bark and sappy part of the wood, that it formed a bud, and eventually burst forth in leaves and a stem. Observing farmers know, that white clover and other grasses, ofter. spi ing up spontaneously, upon lands natural to grass, when no seed has been sown; and gardeners as well as farmers know very well, that weeds of various kinds, as well as several species of grass, spring up in gardens, corn fields, and other rich cultivated grounds,in wet seasons,in the months of August and September, as well as in June and July. All the seeds that were in the ground, would grow early in the season or rot; and hence the weeds and grass that spring up in Aulgust and September, must be of spontaneous growth, growing without seed, other than the vital element existing in the earth and the atmosphere-acting as an organizing principle and force. Farmers, living in new countries, know that when heaps of brush or logs are burnt in the woods upon moist rich land, fire weeds soon spring up, and cover the ground. As the fire would kill all the seeds of weeds, if any, upon the ground or near its surface, and the winds could not easily carry seeds far into the woods, it is impossible to account for the cause of the growth of such weeds, unless the earth, and the elements and forces of nature, produce them spontaneously without seed. The fire weed is also a peculiar weed, which grows only where the ground is covered with ashes; and hence it does not spread, and is almost unknown, in old countries. Plants and trees, and all forms of vegetation, generally grow from the seeds of parent plants, of like SPONTANEOUS VEGETATION. 121 kind; but it is impossible to account satisfactorily for the origin of the great amount of vegetation, plants, and trees upon the earth-for their existence upon coral islands of comparatively recent origin-and for their springing up in such abundance where the country has been recently desolated by fires, and all seeds, and nearly all the roots and germs of vegetation destroyed-unless we suppose that they are often produced by the forces of nature, and spring up spontaneously-or suppose that the creative power of Cod has been constantly exercised in forming new creations of such things, or creating the seeds or germs, from which they spring. Many facts, which constitute strong and clear evidence of spontaneous vegetation, are presented by Prof. A. Winchell, late of tile University of Michigan, in his work entitled, " Sketches of Creation." Prof. Winchell says (p. 250): " Nothing is a more common observation than to see plants making their appearance in situations where the same species was previously unknown, or for a long time unknown, and under circumstances such, that the supposition of a recent distribution of seeds is quite precluded." Again he says (p. 251(:'Earth thrown out of cellars and wells is generally known to send up a ready crop of weeds, and not unfrequently, of species previously unknown in that spot. In all these cases, after allowing for all known possibilities of the distribution of seeds by wrinds, birds, and waters, it still seems probable that germs must have previously existed in the soil." " Similar sudden appearances of new forms take place, when a change is effected in the chemical nature of the soil. * * * How soon does a dressing of undecomposed muck, or peat, or saw-dust, develop a crop of acid-loving sorrell; and how readily is it again repressed by some alkaline manure? Let the waters of a brine well saturate a meadow, and how long before we witness the appearance of the maratime Scirpus and Triglochin, or some other salt-loving plant, whose germs, unless spontaneovsly developed, must have lain dormant at a greater or less depth." " Something of the same nature is witnessed on the disappearance of dominant species, whether through the agency of man, or the processes of nature. It is well known that the clearing of a piece of forest and the burning of the brush, 122 SPONTANEOUS VEGETATION. is almost always followed by the appearance of certain unwonted plants, known as'fire-weeds.' In many cases it would seem highly improbable that the seeds of such plants had been recently transported to such situations, at the moment when the disappearing forest admits the conditions essential to their growth." * * * Of the same nature is the recurrence of particular forest growths upon the same soil. Not unfrequently the second growth is of a very different nature from the first. In the old fields of Virginia and other Southern States, the soil, cleared originally of the deciduous forests, and then abandoned after years of continuous cropping, sends up a growth of pines, instead of deciduous trees." "Again he says, (p. 262): "Some well-diggers in a town on the Penobscot liver in Maine, about forty miles from the sea, came at a depth of about twenty feet upon a stratum of sand. * * * This (sand) was scattered about the spot on which it had been found. * * * In a year or two it was perceived that a number of small trees had sprung from the ground over which the sand had been strewn. These trees became objects of strong interest * * * At length it was ascertained that they were Beach-plum trees; and they actuzally bore the Beach-plum, which never had been seen except immediately upon the sea shore." " Referring on page 263 to the well and Beach-plum story, the Prof. says: " Such a fact, so striking, and so circumstantially recorded, is only of the same nature as others less critically noted, which daily pass before our eyes, in the upspringing of vegetable forms, from diluvial materials, thrown out of wells, cellars, and other excavations." Now COMES THE SPECULATIVE, AND MARVELLOUS SIDE OF rl{E PROFESSOR'S WORK AND VIEWS. The common belief, inculcated by Ecclesiastics for ages, that all such plants and trees, weeds and grasses, sprang firom seeds of parent plants and trees, transported by winds and waters, birds and men, he could not believe; the evidences to the contrary were too strong; and hence lhe distinctly repudiates it. rTo assert that they were special creations of God, does not accord with his views of science, and of the forces of nature-beliveing as he does, that the forces of nature act as secondary causes, and agencies of Deity. He was puzzled, and yet anxious to show hinmelf capable of accounting for the phenomena. SPONIANEOUS VEGETATION. 123 He commences chapter XXIII, on page 250 by saying: "I venture here to enunciate a view, which to many may appear incredible. For some years past I have been inclined to believe that the germs of vegetation which flourished upon our continent previous to the reign of ice, and many which must have been buried from twenty to one hundred feet beneath the surface of the glacial rubbish, may have retained their vitality for thousands of years, or even to the present time." When we consider the difficulties that farmers have, in curing, keeping dry, and preserving their seed corn (maize), to ensure its growth-and the fact that a large portion of the garden seeds kept over more than one winter, will not grow-the announcement of such a novel opinion by a learned professor of the natural sciences, is truly surprising. The facts that I have heretofore quoted, are presented by him, to support that novel opinion-by me, they are presented to prove the theory of spontaneous vegetation. How differently men reason! Oh, Science! what a ghostly figure thou becomest, when the mind is clouded with false dogmas and prejudices! To account for'fire-weeds, he says (p. 252): " It can hardly be douzbted, that the seeds existed in the soil, ready to germinate whenever free sunlight, warmth, and atmospheric air, should be permitted to rouse their latent energy." Quoting from the learned work of George P. Marsh, on "' Man and Nature," Prof. Winchell continues (p. 254). He (Marsh) says, " Earth brought up from wells or other excavations soon pr oduces a harvest of plants, often very unlike those of the local flora. He (Marsth) goes so far as to express the opinion, that earth ejected from considerable depths by a certain earthquake convulsion, (t6 which reference is made), and which soon became covered with vegetation,'never observed in that region before,' must have brought up with it the seeds,from which the novel vegetation sprang,-under the influence of an air and 124 SPONTANEOUS VEGETATION. sun-from depths where a previous convulsion had buried them, ages before." The question may properly be asked-ARE THERE ANY LIMITS TO HUMAN CREDULITY? Again the Professor says: "From such facts as those which have been cited, it seems to be proven that the seeds of plants may retain their vitality in the soil and subsoil, at least for quite a number oj years. The facts show that the germs exist in places where we have no knowledge of their introduction, and in places where they could not probably have been introduced during the human epoch. Whence comes the germs of that vegetation, which is every where springing up, in'situations in which recent seeds could not have been distributed? This question has agitated the mind of many an inquirer, who would have shrunk from the solution which I venture to offer" Again he says, (p 260): "The seeds of the various'fireweeds' which spring up on a forest clearing, after the brush has been burned off, must have reposed in a latent state, during the existence of the forest whose disappearance is the signal for the resumption of their vital activity. The same is true of the seeds of the old field pines,which have probably lainfe)r an age or more,awaiting the maturity and destruction of the deciduous forest which usurped the soil. loaw many ages may they have lain there?" In explanation of the origin of the Beach-plum trees-growing out of sand taken out of a well in Maine, he says: " The trees had therefore sprung from seeds which were in the stratum of sea-sand that had been pierced by the well diggert." It is dif-.icult to conceive a more perfect non-sequitur. In conclusion the professor says, (p. 263): "While, however, the case is fir from deemonstrated, it may fa:rly be submitted, that the explanation of certain facts afforded by this theory, is less presumptious and improbable, than the supposition of spontaneous generation, the fortuitous distribution of seeds by any modern agency, or any other explanation that has ever been offered." It is really melancholy to see scientific men bending under the influences of old and unsound, relgious dogmas and prejudices, and laboring to invent Munchausen theories, to account for the common phenomena of nature, by methods that are contrary to the dic SPONTANEOUS GENERATION. I25 tates of reason and common sense. Why not stand up to the rack, face the music, as Professor Lewis has done, and insist that religious dogmas and prejudices must yield to the developments and the lights of science, and common sense? The acts, works, and revelations of God, cannot be inconsistent with each other; and those who believe in Divine revelation,and believe also that God is the maker and ruler of the universe, should not hesitate to so interpret the volume of revelation, as to render it consistent with the volume of nature. True religion cannot suffer from interpretations of scripture, which will harmonize it with the phenomena of nature. Spontaneous generation. The spontaneous generation of animals is susceptible of clearer and more direct and positive proof, by experiment, than the spontaneous production of plants. It has been proven by a great number of persons, by hundreds, and even thousands of experiments, during the last hundred years or more. The second volume of the Encyclopedia Britannica devotes nearly a dozen pages to the subject of animalcules, stating many experiments-showing how they are spontaneously developed, from vegetable infuisions. It says, (p. 27): " When paste is allowed to stand till it becomes sour, it is then found to be the habitation of numberless animalczLles, which may be discovered by the naked eye; and though their form cannot be perfectly distinguished, their. motion is very perceptible, and the whole paste will seem to be animated." They are called anguilla, or eels. " The most remarkable property of these insects is, that they are viviparous." " It says: " Animalcules of a similar kind are found in vinegar; and like those already described, are found to be viviparous." Again it says, (p. 31): " The Animalcula Infusoria take their name from being found in all kinds, either of vegetable or animal infusions. Indeed there is scarcely any kind of water, unless impregnated with some mineral substance, but what will discover living creatures. Mr. Leeuwenhock says, 126 SPONTANEOUS GENERATION. that at first he could discern no living creatures in rain water; but after standing some days, he discovered innumerable animalcules, many thousands of times less than a grain of sand." It gives an account of experiments made by Mr. Ellis, in I768, and the production of animalcules, first with an infusion of potatoes, and afterwards of hempseed. Mr Ellis says: "I procured hempseed from different seedsmen. some of which I put ifto new river water, some into distilled water, and some into very hard pump water. The result was, that in proportion to the heat of the weather, or the warmth tin which they were kept, there was an appearance of millions of minute animalcula, in all the infusions; and some time after, some oval ones made their appearance." Prof. Henry James Clark, of Harvard University, in his work entitled," MIND IN NATURE, 1r the origin of life, and the mode of development of animals," has presented the subject of spontaneous generation, in a very clear light. To support and illustrate his views, he presents in his work several extracts from a paper of Prof. Jeffi'ies Wyman, ot the same University, published in I862, in the American Journal of Scienceentitled —' EXPERIMENTS ON THE FORMATION OF INFUSORIA IN BOILED SOLUTIONS OF ORGANIC MATTER, ENCLOSED IN HERMETICALLY SEAILED VESSELS, AND SUPPLIED W'ITH PURE AIR." "The materials of the infusion were put into a flask, and a cork, through which was passed a glass tube drawn to a neck, was pushed deeply into the mouth of it. The space above the cork was filled with an adhesive cement, composed of resin, wax, and varnish. The glass tube was bent at a right angle, and inserted into an iron tube, and cemented these with plaster of Paris. The iron tube was filled with wires, leaving only a very narrow passage way between them." " In the first and second methods, the solution in the flask is boiled, and at the same time the iron tube filled with wires is heated to redness. While'the contents are boiling, the steam formed expels the air from the flask; when the boiling has continued long enough, the heat is withdrawn, from beueaththe flask,and,as the steam condenses,the air again enters through the iron tube, the red heat of which is kept up, so that all organisms contained in the air are burned. In both meth SPONTANEOUS GENERATION. 127 ods, the flask is allowed to cool very slowly, in order that the entering air may be as long as possible in passing through the iron tubes, and thus the destruction of its organic matter insured. When cold the flasks are sealed with the blowpipe." " The time during which the infusions were boiled, varied from fifteen minutes to two hours; and tbe amount of infusion used was from one twentieth to one thirtieth of the whole capacity of the flask-the object being to have the materials exposed to as large a qnantity of air as possible" " In the account, especial mention is made, in most instances, of the time of the formation of the filn. This is always the first indication which can be had, without opening the flasks, that minute organisms are developed; it is in fact made up entirely of them, as has been proved by repeated experiments of the microscope." "After the flasks were prepared, they were suspended from the walls of a sitting room, near the ceiling, where they were exposed to a temperature of between 70 deg. and 8o deg. F., throughout the day, and nearly the same during the night" After stating the details of each experiment, the materials used, and its results-showing that in different flasks vibrios, bacteriums, monads, and other species of animalcules were produced, often in large numbers, Prof. Wyman says: " We have here a series of thirty three experiments, prepared in different ways, in which solutions of organie matter, some of them previously filtered have been boiled at the ordinary pressure of the atmosphere, for a length of time, varying from 15 minutes to two hours, and exposed to air purified by heat." "In many instances, a solution like that in sealed flasks, and boiledfor the same length of time, was exposed to the ordinary air of the room, in an open flask. Although the same forms were found in the two, they appeared much more rapidly in the open than in the closed vessel." "The result of the experiments here described is, that the boiled solutions of organsic matter made use of, exposed only to air which had passed through tubes heated to redress, or enclosed with air in hermetically sealed vessels, and exposed to boiling water, became the seat of infusorial life." "The experiments which have been described, throw but little light on the immediate source from which the organisms in question have been derived. Those who reject the doctrine of spontaneous generation in any of the forms 1 28 SPONTANEOUS GENERATION. in which it has been brought forward, will ascribe them to spores contained either in the air enclosed in the flask, or in the materials of the solution." "' Those who advocate the theory of spontaneous generation, on the other hand, will doubtless find in the experiments here recorded, evidence of their views. While they admit that spores.and minute eggs are disseminated through the air, they assert that no spores or eggs of any kind have been actually proven by experiment, to resist the prolonged action of boiling water. As regsrds Vibrios, Bacteriums, Spirillums, etc., it has not yet been shown that they have spores: the existence of them is simply inferred fiom analogy. It is certain that Vibrios are killed by being immersed in hot water, the temperature of which does not exceed 200 deg. F. We have found all motion, except the Brownian, to cease even at 80o deg. F. We have also proved by several experiments, that the spores of common mould are killed, both by being exposed to steam, and by passing through the heated tube used in the experiments described in this article. If on the one hand, it is urged that all organisms, in so far as the early history of them is known, are derived from ova, and therefore from analogy we must ascribe a similar origin to these minute beings, whose early history we do not know, it may be urged with equal force on the other hand, that all ova and spores, so far as we know anything about them, are destroyed by prolonged boiling; therefore from analogy, we are equally bound to infer that Vibrios, Bacteriums, etc., could not have been derived from ova since these would have been destroyed by the conditions to which they have been subjected." " Prof. Clarke says: "Prof. Wyman has since been so kind as to show me some other experiments, which prove that these same bodies which are developed in sealed flasks, are killed at a point far below that of boiling. He placed large quantities of each kind, viz., vibrios, bacteriums. kolpedas, etc, each in a separate test-tube, and each tube with a thermometer in a water bath, and applying heat to the bath, he examined, from time to time, as the temperature was raised, portions of each set with the microscope. Some of the animalcula survived the heat up to 125 deg, and others up to 130 deg., but in no instance did any of them live wlhen the temperature was raised to 150 deg.-which is 62 deg. below boiling, 212 deg. F." Such experiments, with such results, ought to be regarded as settling the question beyond all reasonable grounds for doubt; but as there is no limit to human creduilty, so there is none to caviling about ti.e effect of evidence. Dogmas and prejudices, SPONTANEOUS GENERATION. I29 theories and fixed ideas and opinions, form not only the stand-points and land-marks which guide human reasoning-but they in some measure form parts of the constitution of the complex machinery which we call mind. This is shown most clearly in some cases of insanity. Hence different minds are differently constituted. Those who deny that God operates through secondary causes, and believe that every birth and every death also, is caused by his direct and immediate agency, can never be convinced of the truth of spontaneous generation. They must be left to the blindness which results from their erroneous dogmas and prejudices. In my view, the reproduction and multiplication of plants and trees, by budding, by slips set in the ground, and every other mode except their germination and growth from seeds grown and matured upon parent plants, is but a mode of spontaneous vegetation; and every origin and birth of an animalcule, or other animal, except such as are begotten by parents, is only a mode of spontaneous generation. The atmosphere in certain states, in hot weather, and water also in certain conditions, when saturated with the juices and sap of vegetation, sometimes swarm with animalcules, and germs of living beings. Late in summer they may have been hatched from the eggs of flies and other insects; but our long and cold northern winters not only kill nearly all the flies and insects of the preceding year, but destroy the vitality also of the most of their eggs and spores-and the question arises, how in the spring and early summer, such animalcules are, or could be formed in any great numbers? Is there any mode by which the most of them could possibly be formed, early in the season, except spontaneous generation, or the direct act and creation of God? Animalcules and all animals of every form and nature, must originate either in germs, eggs, spores, or as special creations of God. I can conceive of but three possible modes, in which the germs, eggs, and 9 130 SPONTANEOUS GENERATION. spores, of living beings of a material character can, or at any period of the world's history, could originate. They are, Ist. In the bodies of parents. 2d. By means of spontaneous generation. 3d. By the direct act, and immediate creation of God. And I know of but five modes in which living beings of any kind, whether animalcules or the more perfect orders of animals, can, or at any period of the world, could originate. They are, Ist. From germs or eggs, formed in the body of a female parent, by means of'sexual generation — being the product of two parents-male and female. 2d. From germs, eggs, or spores, formed in the body of a female parent of the lowest orders of animals, without sexual intercourse. 3d. By self-division-whereby two or more living animals are formed out of onfe. 4th. By spontaneous generation without parents. 5th. By the direct act and creation of God. The airst mode named, may properly be called the normal mode-as it is the only one in which any and all animals of the higher orders are multiplied. The second and third modes named, I think may properlybe regarded as only different modes of spontaneous generation-though of this there will be differences of opinion. Worms often, if not generally, originate, in the decomposition of animal and vegetable organisms. They sometimes appear to originate spontaneously in the bodies of living persons, as well as of animals; and dead bodies in hot weather, soon swarm with worms, whether they are exposed to the atmosphere, or are buried in the earth-and even when confined in coffins, and buried several feet in the ground. There seems to be no reason to doubt their spontaneous origin. The work of M. Paul Janet, a learned professor and author of France, entitled " The Materialism of the Present Day." first published in i864, contains chapters on matter and motion, on matter and life, and SPONTANEOUS GENERATION. 13I on spontaneous generation. He is so extremely and intensely hostile to the common views and theories of the materialists, that his views inrmany cases run into and blend with Pantheism, and are in some measure Pantheistic. They are also intensely negative —and neither affirm nor state any view or theory as in accordance with his own opinions-but onlv as antagonistic to, or inconsistent with, some other view or theory. M. Janet collects a great variety of opinions and authorities, experiments and arguments, to overthrow the theory and doct'ines of spontaneous generation. None of them however are sufficient to destroy the force, or to lessen materially the conclusive character of the experiments of Prof. Wyman. He argues that the experiments of M. Pasteur show that the infusorial life produced by such experiments,come from germs in the atmosphere. There can be no germs of life floating in the atmosphere, coming from living parents, except in hot weather-as late as midsummer; and it should be borne in mind, that Prof. Wyman's experiments were made in cold weather, in winter, in the months of February and March-when no such living germs could be floating in the atmosphere; and his apparatus and methods were such, as to destroy all such germs by heat, if there had been any. If there be any distinction between what is called Pantheism and Necessitarianism, the former is the most reasonable; for Pantheism may allow some freedom of action to the sp)irit, which the Pantheists call Divinewhile Necessitarianism allows no freedom of action whatever. Nor can I see any substantial distinction between Pantheism, and that system of Theism, which denies the use of secondary causes and agencies, concentrates all the forces in nature in one Supreme Cause, and attributes all action and all motion in the Universe, to the direct and immediate agency of that one Great Cause. The theory of spontaneous generation is based upon vitalism-upon the theory of a vital organizing 132 CHARACTERISTICS OF MAN. element in nature. Both vitalism and spontaneous generation are in harmony with the theory of a spiritual nature in man, or spiritualism, and with the existence of a Divine Creator, who governs the Universe, mostly by and through secondary causes and agencies. Vitalism, with spontaneous generation based upon it, forms the only central system which I can conceive, between the chemico-mechanical theory of materialism on the one side, and Pantheistic materialism on the other; and those who deny vitalism and spontaneous generation, in order to avoid the chemico-mechanical theory of materialism, necessarily run into the opposite extreme, and fall into Pantheistic Materialism. It does not come within the purview of this little work, to discuss the merits and demerits, nor the proper limits which should be assigned to the development theory; therefore I shall not attempt to inquire into the origin of man, but pass on to discuss the subject of his place in the Universe. Characteristics which distinguish man from other animals. Though man is classed in creation as belonging to the animal kingdom, yet he has physical as well as intellectual and moral characteristics, that distinguish him from other animals, some of which have been often dwelt upon by anatomists and physiologists-by scholars and by philosophers. His superior physical organization and faculties are, Ist. The organs of voice, which enable him to express his wants and his ideas, by articulate sounds, and the use of language. 2d. The formation of the human hand, thumb and fingers, and their adaptation to labor and industry; and 3d. The formation of the joints of the hip, knee, and elbow-which are adapted to an upright position, and to labor and industry-while those of most quad CHARACTERISTICS OF MAN. I33 rupeds and other animals are not so adapted, and those joints of the Ape, Baboon, and Gorilla races of animals, are inferior to those of man in their adaptation to such purposes. All such views and arguments, which show the superiority of man, are legitimate, and have an important bearing upon the subject; but I view the question differently from most men, examine it from a different standpoint, and look upon the superior physical organization of man as furnishing evidence, not only of superior physical faculties, but also of superior mental faculties. If a horse or other animal without a hand, and without a voice and the use of language, had as much natural intellect as Julius Caesar or Napoleon Buonaparte, his physical deficiencies would render it impossible for him to accomplish much, other than mischief. But the hands or fore feet of Apes and Baboons, Monkeys and Gorillas, are nearly as perfect and well fitted for labor and industry, as those of man; and I can scarcely entertain a doubt, that the plastic powers of the organizing principle of nature, and of living organisms, are such, that frequent use as instruments of labor and industry, would eventually fit them for such purposes-and so change their hip and knee joints, as to fit such animals to walk erect with more facility than on all fours. I think also, that if they had as many and various ideas to communicate as the lowest savages upon the earth have, their frequent and constant efforts to communicate their ideas, would have developed organs of speech, and led to the formation and use of an imperfect language, by which they could be understood by each other. I therefore regard such physical deficiencies of the Ape, Baboon, and Monkey species of animals, as evidence that they are more deficient in intellect, than in physical form and capacity. Is there not reason to believe, that much of man's physical, as well as his mental superiority, has been produced, by the use of his physical faculties, guided by a vastly higher order of natural intellect with which he has been endowed by his maker-whereby all his 134 CHARACTERISTICS OF MAN. faculties, both mental and physical, have been developed and improved? Peoples, nations, and races of men, as well as individuals, improve-but animals never do, except when trained by man. Man has been defined as an animal that cooks his food. This is one of the clearest definitions that has ever been given, to distinguish him from other animals. Though Baboons, Monkeys, and Apes are well known to man, and have hands sufficient for such purposes, no one of them has ever been known to cook his food, or to attempt to do so. Fire is one of the most useful agents that man possesses. It is used not only by civilized'man, but savages use it to cook their food-to warm and dry themselves when cold and wet-and also to burn over and improve their hunting grounds. Though cats and dogs learn the warming influences and comfort of fires, and like to sit or lie down by them, no animal ever collects fuel, and kindles a tire foi himself. Apes and Baboons,Chimpanzee and all the various species of monkies, have hands sufficient for labor and industry, and in that respect are superior in their organization to all other animals; yet they do not make their hands of any value to them for industrial purposes; and in intellect and docility, they are inferior to dogs, horses, elephants, and several other animals. The savage natives of hot climates as well as cold, use fire for various purposes, and plant and cultivate grain and vegetables of various kinds, to supply themselves with food; but nothing of the kind is done by apes or baboons, the chimpanzee, or any other species of animals. Many animals collect and store away for future use, products that are useful for food; but no animal ever had sufficient forethought and providence, to plant seed, and cultivate for himself. The period of the early inhabitants of Europe, before the use of iron or copper was known to them, is called the stone age. The people were in a savage state, and yet they invented and made of stone, axes and hatchets, wedges and arrow-heads, and diverse CHARACTERISTICS OF MAN. I35 other instruments of industry and weapons of war-as was the case also with the natives of America. But while the Ape, Baboon, and Chimpanzee are said to use clubs and stones as weapons to fight with, they have never been known to invent or to make any instrument whatever, either of industry or war. Savages, as well as civilized men and women, choose companions for life, and live in families, as well as in communities or tribes. Many animals are gregarious, and live in what may be called tribes. Land animals very generally choose their mates annually, during the breeding season, and live in what may be termed family relations, while breeding and raising their young; but when their progeny come to maturity, the family relation ceases, they separate, and there is, thereafter, no more affection or regard between parents, or between parents and descendants, than there is between other associates-not connected by any natural ties of blood or affinity. Animals manifest cunning to steal, and to conceal their offenses-caution and fear of punishment-and sometimes affection and devotion, pity and sorrow, sadness and melancholy-pining away in confinement, or for the loss of their associates; but we have no evidence that they ever feel remorse for misdeeds, or consciousness of having done wrong, or in any way manifest any conscience or moral sense. Here then is another broad distinction between the man and the brute. Man that is not brutalized by education, nor by habit, has a moral sense and a conscience, that often restrain him from doing wrong, and trouble him when he has done it-though it must be confessed, that the consciences of a large portion of mankind are very weak, in this age of avarice, and of ambition for wealth, display, and power. The several characteristics that I have named, which distinguish man from all other animals, form a gulf of separation between him and them, which they can never pass, without the Creator,s aid. However much man may be degraded, the beast can never be elevated to his level. 136 CHARACTERISTICS OF MAW. Animals below man are creatures of nature-incapable of much farther development or improvement by education. Man, on the contrary, is a creature of education and habit. His mind, and his moral faculties and nature, are all wonderfully developed, and increased in activity, strength, and volume, by education. Acquired knowledge constitutes the great fountain and source in which the currents of thought in his mind originate, and from which they spring; and habit forms the channels in which they run and flow. Habits of thought and opinions, feelings and sentiments, form the standpoints from which men reason; and acquired knowledge and maxims constitute landmarks which guide them in their reasoning,and direct their action. Acquired knowledge, fixed opinions, and habits of thought, may be said to constitute parts of the human mind; and hence the mind is expanded, developed, increased in volume and power, and materially changed, by education and habit, by modes of living and intercourise, as well as by moral and religious opinio.s. and by systems of government and law. Man's ph) s'cal nature is also developed and changed by labor and;niustry, by diet and drink, as well as by climate and n,! les of living; and his mental and physical natures m,'ually acting and reacting upon each other, have great influence in forming his constitution and character. By means of such influences the people of every climate and nation, acquire to some extent, a type of character peculiar to themselves, which has been called national character. And hence the differences between civilized man and savages, or barbarians-between Catholic and Protestant peoples-between Christian and Mohamedan nations-between Jews and Hindoos -between different Pagan peoples-and between peoples of cool and temperate, and those of hot climates. But a mistaken idea has crept into the public mind in this country, that the education of the schools tends CHARACTERISTICS OF MAN. 137 to lessen crime as well as vice. It undoubtedly tends to elevate men in thought and action-to increase the efficiency and productiveness of their industry-to improve their well-being-and to save them from the grosser forms of vice and corruption-but at the same time, it multiplies their artificial wants, tends to stimulate their ambition and avarice, and to increase the variety of crimes, and multiply the number of them. In fact, there is scarcely any human good, which is unmixed with evil. The wealth and the luxury, the extravagance and the display of the rich, and of those who ape the style and customs of the rich, tend to engender pride and indolence, prodigality and corruption, in all classes of people. They expose the young, the poor, and the weak, to various temptations which they cannot easily resist; and invite great numbers of persons to the commission of crime. If you wish to find a community in which there are few criminals and few crimes committed, you must go among plain and simple-hearted peasantry and mechanics in the country and country villages, who have but little scholastic education and very little wealth, who live in A country where the most of the officers of government are not frequently elected by universal suflfrage, and where there are no political cliques or rings, clans or trades-unions, among the people. You must keep out of such cities as London and Paris, New York, and other large commercial centres, where wealth and luxury, extravagance and prodigal display tend to corrupt all classes of the people. And yet, notwithstanding the prevalent ambition for display, the greed for wealth and office, and the wide spread corruption in our country, there are persons in the large cities as well as in the country, who are imbued with a real Christian spirit, and have a true nobility of character-whose natural selfishness is so moderated by a sense of justice and regard for the good of their fellow men, that they can be just and truthful, and can act fairly and honestly, in all their 138 CHARACTERISTICS OF MAN. transactions-who manifest a, proper degree of public spirit, patriotism, and regard for the general good. Such persons discriminate between the virtuous and the wicked, and do not vote for bad men, because they are nominees of their party. They do not manifest a sickly sympathy for convicted criminals, and persons charged with crime-but show a proper regard for the safety and welfare of the community. A proper sense of justice and regard for the public safety require that criminals should be punished for their crimes; and it is the duty of every citizen to expose crime and to aid public officers, in a suitable manner, in bringing criminals to justice. The public mind of our country has been demoralized and debauched by false sentiments of humanity, and sympathy for convicts, and persons charged with crime. The criminal laws, the plainest evidence, and the pardoning power, have all been perverted to shield criminals from the punishment that is justly due for their crimes. Animal propensities and passions induce such crimes as fornication and adultery, prostitution and rape, gluttony and drunkenness, and sometimes homicide, without much premeditation; but it is avarice, greed for office, and ambition for power and dominion, for display and a show of superiority, which stir up dissension and strife, and induce persons to lie and to cheat, to swindle and to embezzle, to forge and tocounterfeit, to commit burglary and piracy, perjury and bribery, and to commit murder also, in most cases, when life is taken. It is not animal propensities and passions which directly incite the commission of such crimes; but intellectual passions, which are common to man only-being in a great measure generated, developed, and fostered by education, by artificial states of society, by wrong sentiments and opinions, by false systems of law and government, and by Wrong views of human rights and duties. The passions which prompt the commission of such ciimes, are but little CHARACTERISTICS OF MAN. 139 known among savages, and among the poor peasantry of the country, under monarchical governments. So long as selfishness and avarice, greed for office and party spirit, govern our politics as well as our social life, and there are ambitious and corrupt men, having money, and willing to use it for corrupt purposes, they will find voters ready to sell their votes, and men both in office and out of office, ready to sell their votes, and their power and influence-notwithstanding the prating about the honesty and purity of the people. The corruptions and gigantic frauds in the city of New York-the corruptions in Congress, in Kansas and South Carolina, in Florida and some other states-and the partizan strifes and corruptions, frauds and perjuries, usurpations of power and perversions of law in Louisiana, remind us that the frequent election of nearly all officers of government by popular vote, with universal suffrage, is but an experiment, and as yet a very doubtful experiment, among such a people. It may well be doubted if such a government can be maintained any where below the 35th degree of latitude. Such is the character of the animal called man -when intellect, avarice, and ambition predominate over moral sense. Neglect entirely the cultivation of the mind, and man approximates to the character of an animal. Cultivate only his intellect and his physical faculties, and stimulate his avarice and ambition, leaving his moral faculties uncultivated and undeveloped, and his character assimilates to that of fallen angels and demons. Selfishness and party spirit, and the greed for wealth and for office, have stifled the moral sense of the country, and destroyed nearly all public spirit, patriotism, and regard for the general good. Party organizations, party spirit, and our system of elections, whereby minorities are virtually unrepresented in legislation and in the administration of the government, lie at the root of many of our political evils and corruptions. When a few votes will turn 140 CHARACTERISTICS OF MAN. the scale, one way or the other-(as is often the case), the majority system encourages intrigue and bribery, and every species of corruption among voters, and party leaders and candidates, and also among officers that receive and canvass the votes, and certify the result. With triple districts and cumulative voting, the minority would generally elect one of the three; and when parties are nearly equal, neither party could gain more than one representative of the three, instead of the whole, by getting a majority of the votes; and hence the inducement for fraud, bribery, and corruption, would be much less than it is now —under the majority system. Man is by nature selfish, but not naturally so corrupt as he is made by partizan influences, and our vicious majority system-whereby politics are made a gambling ganle-the majority taking the whole, and the minority none. CHAPTER XI. ORIGIN OF MATTER-ATOMS OF MATTER INDESTRUCTIBLE AND UNCHANGEABLE-ORIGIN AND PROPAGATION OF PLANTS, ANIMALS AND MAN-THEORY OF EVOLUTION-MATTER AND FORCE-VITAL FORCE AND INTELLECT —CAUSE AND EFFECTUNIVERSAL ATTRACTION-AND AN IMAGINARY ETHER. The Origin of Matter. The origin of matter is beyond the domain of human knowledge. It is to man not only unknown, but unknowable. His faculties are so limited that he cannot imagine, nor conceive, how matter could have originated. He cannot conceive how it could have been created out of nothing-how it could have been eternal, nor how it could have come into existence in any manner whatever. All he can know is the simple fact of its existence, and must content himself with studying the phenomena of its action,and the evidences of its action in the past; and must infer its properties and forces from its action. The scriptures do not explain the mystery. Contemplating matter as in existence in a chaotic, and perhaps a nebulous condition, we can form some imperfect conceptions of the gradual formation of our earth and solar system, and of some of the changes which the earth and its surface and atmosphere underwent, before it was fitted for the abode of man. I42 ON MATTER. The Atoms of Malter Indestructible and Unchangeable. That matter is indestructible is generally believed by chemists, and seems to be proven by experiments in chemistry. When compounds are destroyed by combustion, or by chemical action, the atoms thereof appear in new combinations, and form new compounds. However changeable compounds may be, the elementary atoms of which they are composed are supposed to be absolutely indestructible and unchangeable, either in form, substance, or properties. Whatever may have been the origin of matter, and when its orgin, we have reason to believe, that for millions of years past, there has been no increase or diminution of the number of atoms of any class or element of matter in the universe, and no change in the substance, form or properties thereof; that though new compounds were constantly forming for millions of years perhaps, while the chaotic materials of which our globe is composed were drawing towards each other, becoming one body, and contracting, and the crust of the earth was forming and growing thicker, and before it attained a condition fit for the abode of man-not an atom of matter was created during that long and unknown period. [he Origin and Propctgation of Plants. When portions of the earth's surface were raised by internal convulsions above the ocean, and became dry land, we have reason to believe that grass, herbs and trees soon sprang tp, and the earth was clothed with vegetation; but long before that period the waters teemed with shell-fish and the lower grades of marine animals. The question arises, how did plants and animals first come into existence. Did their origin involve the creation of new matter-of additional atoms and elements of matter, or only new forms, or PLANTS AND THEIR ORIGIN. I43 ganisms and types, out of the elements and materials previously existing? The teachings of the book of Genesis, as well as the deductions of human reason, are both consistent with the latter theory-that creation in the case of plants and animals is only the production of new combinations, new forms and organisms, from old materials. If so, were they first produced by the direct act of God, or indir ectlyby the spontaneous action of the elements and forces of the material world? Were they not produced by a living principle, co-operating with other elements and forces of nature? There is no more difficulty in conceiving that the first vegetable organism was produced by the spontaneous action of a living organizing principle co-operating with other forces of nature, than in conceiving how, at this day, a blade of grass orof grain can spring from its proper seed, grow up and produce seed in its turn, aud thus propagate itself from year to year, and from century to century. The how-thke modus ofperandi-and the causes and details of the pirocess, are mysteries beyond the domain of human science; and yet we witness the results of such processes every day of our lives. It will not be affirmed by any person of common sense, that the seed of a plant or tree possesses any creative power to originate and call into existence denovo the atoms of matter that will form the future plant or tree, which may spring from it. Nothing of the kind will be pretended; and yet the seed possesses an inherent power, which, when warmed with caloric and swelled with moisture, attracts to itself materials which it absorbs, assimilates and forms into sap and into vessels and fibres-whereby it grows,matures, and forms other seed in its turn. This attraction and absorption of food, assimilation, germination and growth, is a process of nature; and yet it is not a process carried on by chemical attraction, nor by the attraction of cohesion. It is a process very different from that which forms water and crystals, rocks and earths. It is impossible to conceive how vegetable pro 144 PLANTS AND THEIR ORIGIN. cesses can be carried on without some element and force unknown to the chemist-without a vital organizing principle-co-operating with other forces of nature. The vital organizing element, existing in the earth as well as in plants, is itself the germ of the plant, the life and active element of the seed, without the shelland when that is admitted, there is no more difficulty in conceiving how plants can be developed from the natural seed existing in the earth, than in conceiving how they are produced from seeds grown upon other plants. The same course of reasoning applies to the origin, propagation and growth of animals, so far as their physical organization is concerned; but as every animal has intellect, it is more difficult to conceive whence come their intellects. Geologists and the science of Geology inform us, that the surface of the earth has undergone many changes, and suffered many revulsions and upheavals; that it was once wholly covered with water; and that its continents and islands rose above the waters of the ocean at different periods. Whether matter itself be, or be not, eternal, the land animals and vegetation must have had a beginning-an origin. They must have been created at different periods, upon different continents and islands, or been produced spontaneously by the properties and forces inherent in matter. Many islands have been formed in shallow seas and great rivers, within the era of authentic history, which have been very quickly and rapidly clothed with vegetation of various kinds, and covered with large trees,-according to the climate and soil —w hich cannot be accounted for upon any principal but new and special creations by Deity, or by spontaneous generation. The theories that they spring from seeds transplanted to such islands by winds, waters and birds, are too irra tional and whimsical to be worthy of serious consideration. MAN AND ANIMALS. 145 The Ozigin of Alan and Animals. The origin of man, with his wonderful intellectual faculties, is equally obscure as that of the earth. After some rude type of man originated, we can conceive how the mere physical organization of the species was propagated and gradually developed and improved, from generation to generation, under improved conditions and an improving atnosphere; but it is difficult to conceive his origin, and still more difficult to form any clear conception of the origin of the wonderful intellect of every member of the human family,-unless it be an emanation from a Divine Spirit. There is no difficulty in conceiving that vegetable germs and organisms may be formed by the spontaneous action of the vital organizing element, co-operating with other forces of nature; but it being undeniable that animals, and even the lowest grade of insects, manifest some degree of intellect, we cannot conceive how their intellects could originate, or how they can, at this day, be multiplied by propagation-each animal lhaving its own intellect-except under one of the following conditions: st. That intellect, and the degree of intelligence which animals have, is the result, effect and product of the organization of unintelligent matter-or 2d. That some element of' matter, pervading the crust of the earth or the waters of the earth, having a strong affinity for the vital element, is endowed with the property of intelligence, and readily unites with the germs and organisms formed by the vital element, and thus forms the intellect of the animal; or 3d. That each animal intellect is specially created and communicated to the organism by the Deity. The first supposition-that a combination of unintelligent atoms of matter can produce intelligence and intellect, is to my mind inconceivable. It seems to involve an impossibility, and a self-evident fallacy. This supposition is in accordance with the materialistic view of the question. 146 MAN AND ANIMALS. The second supposition is conceivable. It seems rational, in accordance with the phenomena of nature, -with the mode in which the earth has been changed from a state of chaos to its present condition,and clothed with vegetation-and with the mode in which God governs the universe, by means of secondary causes and agencies. It by no means follows, that the origin of the intellects of rational and moral beings like man, is the same as that of the brute creation. The wonderful reasoning powers, great inventive faculties, and elevated moral character of man,when compared with the limited faculties of the brute, occupied with matters of sense only, indicate that the intellect of the former had a higher origin, and has a nobler destiny than that of the latter. The immortality of the soul of man, does not involve nor indicate the immortality of the mind of the beast and insect The Production of Plants and Animals, not the Creation of lVew Matter. We may state the proposition as an absolute truth, (if there be any truth in human science,) that no process of nature, no germination of a plant, and no propagation and production of an animal, can create or originate an atom of matter, or add to the atoms or quantity of matter previously existing in the universe. All such processes are only modes in which changes are effected-by wlhich latent elements are attracted by natural affinities and forces, drawn forth, developed, and presented in new combinations and new forms. Friction produces heat; but it does not, and can not, create an element of matter, nor add to the atoms of matter existing previously. It merely developes and makes sensible elements of heat which were previously latent; it does not create nor add any element o heat to the previously existing stock. EVOLUTION THEORY. I47 The Evolution Theory. The theory of evolution has been supposed by some to solve the mysteries of creation. Evolution is not a creation of matter, but a mere change in its condition and combinations It produces no new atoms of-matter, but merely forins new conmbinations of the atoms of matter in existence. It is not the origin of things, but a mere change in their forms and modes of existence. It is not in any sense a powZer or cause, which creates, orig'inates, produces, or increases the stock of matter in the uzniverse; but merely a process whereby matter is changed in itscombinations, and organized into living animal and vegetable organisms. Not being a cause of the origin or action of matter, but a mere process of action, a power, force or cause of ac/ion must lie behind it, or be inherent in matter itself-which causes atoms and bodies of mlatter to move and produce the changes involved in the process. Forces and powers, acting as causes, are necessary to originate the process of evolution, and to carry on and continue it, after it originated. It is like a complicated machine, which works admirably when put into operation, and its action maintained by a competent motive power; but has no power to move itself. HEence the theory of evolution throws no new light upon either the creation of matter, the fornmation of the earth, the origin of vegetation, animals, or man, or upon tlie science of animal and vegetable physiology. It does, however, throw much light upon the changes in animnals, the multiplication of varieties, and the origin of new varieties and species-arising from the mixture of breeds, changes of climate and food, and different circuinstances and modes of living. Tlhe theory of a vital elemneint in nature, distinct and different from all the other elements —acting as an organizing force, to unite and form other elements of matter into living organisms, if made a basis of the theory of evolution, as thie cause and motive power required to originate and carry on the process, would 4 8 PYNCHON ON MATTER. give the theory a basis of action, and some degree of consistency, so far as regards vegetation and the brute creation. The forces of nature recognized by chemists and by the school of materialists-comprising the chemical affinities and the attraction of cohesion, the action of heat and electricity, gravitation and magnetism, are not sufficient to account for either vital or mental action. Other forces are required to produce the complicated, various, and wonderful action and phenomena, exhibited in plants and animals, as well as by man. Matter-How Defined by Professor Pynchon. Prof. Pynchon says: " The name matter may be given to any substance which is cognizable by any one of the senses. Everything not cognizable by the senses (he says) passes under the name immaterial." His definition is imperfect, for it would exclude from the category the vital element-the living organizing principle-because the chemist cannot separate it from the organism which it has formed, and make it manifest to the senses, as a distinct element, though it may have nearly all the properties which he assigns to the coarser elements of matter. Prof. P. says: " All matter possesses the four properties of Extension, Impenetrability, Inertia and Weighzt. We know (he says) that a body possesses extension from its occup) ing a portion of space; we know that it possesses impenetrability, from its not allowing another body to occupy this space, at the same time with itself; we know that it posseses inertia, from its want of power to change its state, to move, if at rest, to cease to move, if in motion." His statement of the properties of matter, aid some of his illustrations in support of it are unsatisfactory to my mind, and very defective. Not only the action of the chemical affinities, but the movements of the heavenly 6odies in their orbits, the germination, development and PYNCHON ON MATTER. 149 growth of vegetation and animals, and all the physical action in the universe, attest the activity and active properties of matter, and are inconsistent with the assertion that matter is inert. While the intellectual principle is self-acting, and carl originate action in and of itself,andgive motion to itself, independently of all other elements-unintelligent and inanimate matter is not self-acting, and cannot originate action in and of itself alone, nor give motion to itself without the concurrent attraction of some other element or body acting upon it-the mutual affinity and concurreut attraction of the two co-operating to produce motion and change. This incapacity of any element of matter to originate action in and of itself, and to move independently of other elements or bodies, is called inertia. Alatter is inert in no other sense. What is called inertia is a purely negative quality or condition, and not, strictly speaking, a pro]erty of mcttier. It is no more a property than cold is, which is merely the negation or absence of heat. Again, the learned Professor's statement-including weight as a necessary property of matter, excludes from that category electricity as well as caloric or heat. The fact that electricity, exhibited in flashes of lightning, rends in pieces trees, buildings and other material things, is sufficient to establish its material nature; and the equally significant fact, that caloric or heat (call it by whichever name you please) expands all metals and fluids which it permeates, proves beyond a doubt that it occupies space, like the grosser elements of matter. The action and various phenomena of heat, electricity, and the vital organizing element, all show that gravitation or weight is not a necessary property of matter-and that those three elements of matter, and perhaps others, exist without any such property. Prof. P.'s views of matter are tinctured and warped by the mystical philosophy, which has grown up, permeated, and in many respects perverted the physi cal science and literature ot this age. I50 PROPERTIES OF MATTER. Mfy Views of the Properties of Miatter. The properties of matter are: Ist. Substance-or in common scientific parlance, extension and impenetrability, by reason where of it occupies a certain portion of space, and no two atoms or particles of matter can, at the same instant of time, occupy the same space. 2d. Every atom or particle of matter, as well as every combination of atoms, must have form as well as substance. 3. We have reason to believe that every atom or particle of matter in the universe has active properties, which we call affinities and powers of attraction, bv means whereof single atoms as well as compounds and large bodies, virtually act upon and attract each other, and thereby produce constant action and change. The active properties of matter may be classed as follows: Ist. That power of attraction known as chemical affinity, is the affinity or attraction of atoms of different elements of mattter for each other, which causes them to unite and form compounds-either liquids or solids. The affinities of oxygen are so numerous, that it will combine either singly, or in union with other elements, with nearly every element of the material world; while the affinities of nitrogen, hydrogen, carbon, all the metals and all the earths, are very few and limited, each to a small number of other elements; but the chemical combinations of matter are so numerous as to numbeir thousands. 2d. The attraction of cohesion-by virtue of which certain elementary substances and also the molecules of certain compounds are drawn together and adhere together and to each other, with greater or less tenacity. All the metals have great cohesive power; the power of attraction, which holds their atoms together, is very great, which makes them very compact and tough, and renders iron and copper very hard and peculiarly tough and strong. The gases in their PROPERTIES OF MATTER. 15 elementary state as gases, have no cohesive power whatever. Neither oxygen, hydrogen, nor nitrogen, in its original or separate state, has any cohesive power; but when oxygen and hydrogen are combined in forming matter, the particles or molecules of the fluid have a slight cohesive power, as all fluids have. 3d. The mutual attraction between compounds of matter and bodies at greater or less distance from each other, known as gravity, or gravitation. Gravity operates at distances of hundreds of millions, and even thousands of millions of miles, and keeps the planets in their orbits-revolving around the sun. On the contrary, the chemical affinities and the attraction of cohesion operate only at insensible distances. Of caloric, electricity, magnetism and the vital element, I may say, that each has affinities and powers of attraction peculiar to itself-neither of them having any such affinity or power of attraction as cohesion, gravity, or chemical affinity; and hence they are properly classed as imponderable elements. Caloric has strong affinities for, and permeates all the compounds of the material world, and yet it forms no chemical or permanent compounds. Though the vital element, and caloric also, co-operate with the chemical affinities in forming chemical compounds, as parts of animal and vegetable organisms, yet they merely perteate and act with and upon such chemical combinations, without forming any permanent part thereof; for they escape at the death of the animal or plantwhile the texture of the bones and muscles of animals, and the woody fibers of trees, may last for hundreds, and even thousands of years. Though caloric,electricity,and magnetism have certainl affinities for other elements of matter, each peculiar to itself-yet they seem to be mostly governed by their own inherent properties and powers to act upon other elements, which have very little power to act upon them. Not being under the influence of the attraction of gravitation, they are known as imponderable elements, and are often called forces-on account 152 ON FORCE. of their great mobility and power, their peculiar action, and the impossibility of confining them in vessels and jars, as you can confine all the ponderable elements known to the chemist. Force- What is it? The chemical affinities, the attraction of cohesion and gravitation, are each and all properties and forces inherent in matter, and inseparable from the matter of which they are properties. This is very generally believed and taught by chemists; and if it be not true, there is no certainty nor truth in chemistry, nor in any of the natural sciences. It is, to my mind, a self-evident truth, that all force, power, energy, and causes of action bnd change, are inherent properties of substance of some kind, and cannot exist distinct from and independent of substance. I cannot conceive the possibility of a force or cause of action existing separate and distinct from substance. Call it in some instances spiritual substance, if you please, to distinguish it from the grosser elements and combinations of matter; but it must have at least one of the properties of matter-it must occupy space. It is true that the active properties of matter-its chemical affinities and other forces of attraction, cannot be seen by the eye, distinct from matter itself, and are matters of inference only-mere deductions of human reason, from the phenomena of the material world and the changes which the earth and its inhabitants have undergone, and which its atmosphere and its vegetation do undergo during the different seasons of each and every year; and yet such natural affinities and forces are as real to the reasoning mind, as they could be, if we could see and feel them-measure and weigh them. Single atoms of the grossest matter, are so minute as to be beyond the reach of the senses. It is only combinations of numerous atoms which the eye can see; and yet the fact that matter exists in too minute subdivisions to be seen, is none the less a reality ON FORCE. I53 a truth which all chemists, and -all persons of cultivated minds will acknowledge. The living body is constantly supplied with heat-permeated with caloric and with electricity also-but both are latent, and as invisible as the vital principle or the intellect. The forces of nature may be classed as follows: I st. The powers of attraction between the atoms of diftferent elements of matter, known as chemical affinities. 2d. The attractive power of cohesion. 3d. The mutual attraction between bodies and compounds of matter, at greater or less distances from each other, denominated gravity. 4th, The peculiar affinities, powers of attraction and forces of caloric. 5th. The peculiar affinities, powers of attraction and forces of electricity. 6th. The peculiar force, denominated magnetism. 7th. (And lastly)the peculiar affinities and forces known as the vital forces. Forces are Simple and Compour d. The forces of nature are simple and compound. Every element of matter has properties peculiar to itself, differing from the properties of every other element. The properties of elements constitute the simpeieforces of nature, which are as indestructible and unchangeable as are the atoms of matter of which they are properties. When two or more elements are combined, forming a compound, the forces inherent in the several elements of the compound are blended togetherforming a compound force. Compound forces, being the result of many simple forces varying from each other, and often in some measure conflicting, and thus neutralizing and balancing each other, are as changeable as the compounds from which they result, and upon which they depend. The simple forces are not very numerous, as the I54 ON FORCE. elemnents of matter are limited in number; but the compound forces, resulting from combinations of matter, are almost infinitely numerous and various. The Forces of Nature Multifarious and Conflicting. The forces of nature are many, and not one only, as some are inclined to think. They are various and multifarious-numerous and complex-not few, nor simple; conflicting and in some respects antagonistic -not harmonious. Their action results from their variety, and their approximation to general harmony and uniformity of action results from great variety in detail, of antagonisms balanced. Every action and change in the universe, intellectual as well as physical, must be produced by the affinities and properties, powers, and forces inherent in substance of some kind-each element and force producing its appropriate action. As every element has affinities for imore than one other element-oxygen having affinities for nearly all the elements of the material world, and the vital element affinities for nearly twenty other elements, the various combinations of elements, and the forces resulting therefrom, are almost infinitely various. It required a great number as well as a great variety of powers and forces to produce the infinite variety of chemical and physical, vital and mental action, which is exhibited in the universe. It would be impossible even for God to endow any one element of matter with conflicting and antagonistic forces-to make it ponderable and imponderable, active and inert, and to move in all directions atthe same instant of time, and from one and the same influence; and hence, to insure such variety of action he has created a great number of elements, endowed each with peculiar affinities for other elements-so as to produce a great number and variety of combinations and forces. Nature is not simple, but wonderfully complex. VITAL FORCE. I55 There is no unity, but infinite variety of force. Every element and force acts according to its peculiar nature. Like produces like, in all nature's organisms, and operations. Every plant and tree, animal and thought, feeling and impulse, comes from its appropriate germ and force; and it would be as reasonable to expect an oak tree to spring from a pumpkin seed, or a monkey from a grain of wheat, as to expect any living organism to spring from inanimate elements only, or to expect consciousness and thought to come from unintelligent matter. The Vital Force Antagonistic to Gravitation. All the ponderable elements and bodies of matter on or near the surface of the earth, hlave a gravitating tendency towards the centre of the earth, in proportion to their density. This tendency we call weight. There is no element of matter known to the chemist, on or near the earth's surface, except caloric, electricity and magnetism, which is destitute of the force of gravity; and none which, combining with ponderable matter, acts so powerfully in antagonism to the force of giavity as to overcome that force, and raise ponderable elements and their compounds from the earth into the atmosphere. Smoke and steam ascend-not that they are destitute of gravity, or are propelled upward by caloric or any other element, but they ascend for the same reason that feathers and balloons do-because, being lighter than atmospheric air, the latter presses down with greater force than they do, and thus tends to displace them, to occupy their places near the surface of the earth, and to force them up into the rarer and lighter air of the higher atmosphere. The vapor which is formed upon the surface of water and moist earth by the attraction and action of the sun, and raised into the atmosphere to form clouds, is lighter than the lower strata of atmospheric air-and hence it ascends. It has a gravitating tendency, and yet it is carried up, perhaps mostly by the sun's attrac 156 VITAL FORCE. tion, but partly as smoke and steam are carried up,by the heavier atmosphere tending to displace it, and to supply its place,and thus indirectly force it upwards. On the contrary, the sap of plants and trees, though as heavy as water, ascends in appropriate tubes and vessels, without being forced up by the gravitating endency of a heavier element displacing it, and forcing it upward, —as is the case with smoke and other light substances. While smoke and other light substances are raised by the indirect action of gravity, the sap of plants and trees is propelled upwards by the direct action of some element acting antagonistically to the force of gravity. Sap is carried up in appropriate vessels to the tops of trees, from one hundered to two hundred feet from the ground. It could not ascend if it were not propelled by the power of some element acting directly in opposition to the force of gravity. It is impossible to account for its ascent, unless living vegetation contains some elementary substance, unknown to the chemist, which acts antagonistically to the force of gravity, and overcomes its powers. From the action of living organ isms, I infer the existence of an element having power to act ui50o other elements andcompou tzds, to overcome their chemical affinities andg-ravitaling forces, to unite andform them into living organisms, and to carry their apbpropriatefood and sap upward, contrary to the forces of gravity. The force which accomplishes such ends and purposes, has been called by medical men, the vital force. The element of matter, of which that force is an inherent property, may very properly be called the vital element, or living principle. Though the power of attraction of the sun evaporates water, and draws vapor into the atmosphere, to form clouds and rain, the sun never raises a large body, nor a dense body of any size, from the surface of the earth; but the vital element aided and stimulated by intellect and caloric, enables animals of all sizes, weighing from a grain to a ton, to raise themselves VITAL FORCE. 157 from the ground, in opposition to the force of gravity, -to carry heavy burthens-and to move in opposition to violent adverse winds. From lands heavily timbered, with trees from fifty to over an hundred feet in height, zoo cords or more of vWood are often cut from an acre; which,when green, will weigh about a ton to the cord. This 200 tons weight, to each acre of ground-consisting of water, carbon, silica, potash, and other elements of ponderable matter, have been actually absorbed from the earth, and carried up in sap vessels from one foot to over one hundred feet in height. How has this been effected, unless there is in nature some element of matter, which acts antagonistically to the power of gravitation? During the life of an organism the vital element must control-the vital force predominating over gravity and the chemical forces; but when the vital element passes away at death, the chemical forces assume its place, and dissolution soon commences. At first, the organization is perfect, except that the motive power which moved the machinery of life is gone. However perfect all the parts of the organism, it cannot operate itself, nor act without a motive power. Sap never rises in a dead tree or plant. Fermentation is a chemical process, whereby inanimate materials operate upon each other-and cause the lightest to rise, and the heaviest to settle to the bottom; but I know of no element, except the vital element, and no force other than the vital force, which can raise so heavy a compound as the sap of trees and plants-from one foot to an hundred feet or more, above the surface of the earth. The ascent of sap in trees and plants, and of blood in animals, contrary to the force of gravity, presents a problem worthy of consideration. 2 158 INTELLECT DISTINGUISHED FROM MATTER. Intellect or Spirit Distinguished from Matter and Nature. Nature comprises not only all the pon lerable elements of matter known to the chemist, but also the imponderable elements which are destitute of consciousness, intelligence, or any kind of knowledge; and it is impossible to conceive how any combination of them can produce any property or force, power or capacity, which none of the several elements possess. All of those elements are distinguished from spirit or intellect in this-that they are unintelligent matterwhile the latter must be substance endowed with intelligence, consciousness, volition and capacities to acquire knowledge-else it could not act upon, as well as in, a material organism, and produce such effects as it does. Its action indicates that it is a source and cause of action, independent of matter-outside of and above nature-acting, to a large extent, supernaturally. Human consciousness, and all the operations of the human mind, attest to the existence of intellect, as a substance distinct from the organization of the brainas something existing in the living brain, which does not remain in it after death. Many conflicting influences act upon bodies of matter at the same instant of time, and their motions become resultants of the numerous forces acting upon them.'Generally speaking, but one influence, idea, or motive, and never more than two, act at the same instant upon the mind; and it can turn from one to another, and examine each of many, one after another, and choose between them-its action never being determined by what, in mechanics and physics, is called the resultant of many influences. Mind-even the human mind-acts from forces which we call volition. and intelligence, and not from a natural, material, blind and unintelligent force. Intellect is believed to be an intelligent principle, capable of receiving and acquiring knowledge-of perception and conception, of reasoning and acting according WHAT ARE CAUSES. I59 to its knowledge-or arbitrarily. Though it is acted upon by material forces, acting through the physical organization of the brain and nervous system, which very generally control the common mind; yet it is capable of acting, and often does act, contrary to natural forces and influences-with a view to effect moral and religious ends and purposes. The independence of the intellect is shown most conspicuously in resisting evil influences —more conspicuously in its negative, than in its positive action; and hence the import-.ance of having the mind well stored with sound moral principles-to enable it to resist bad and corrupt influences. Nature, and all the elements of matter, are governed by inherent properties and forces which are unchangeable-always the same-never increased or diminished in power-unless by the direct agency of the Divine mind. Hence, their action is uniformalways the same. On the contrary, the human mind is governed by volition, which is changeable and may act arbitrary, and by intelligence, which may be increased and accumulated-which may be true or false, right or wrong, and is generally more or less imperfect. Hence the great diversity of thought, views and opinions of mankind —no two persons thinking alike on many questions. Cause and Effect- What are Causes? There can be but one proper meaning of the word cause, and that is,fforce or power, inherent in spirit and matter, which produces action, motion and change. What the schoolmen and theologians call final causes, are not, strictly speaking, causes, but purposes, or ends to be attained, and not causes. What are called final causes follow action and never precede it-whereas causes always precede action, and produce it. The antecedents in a succession of events are not the causes thereof,as is maintained by Hume and many I60o WHAT ARE CAUSES. other philosophers; but the active forces in nature and mind, by which the succession of events are produced, are the real and efficient causes. The causes of human actions are appetites and passions, wants and desires, avarice and ambition, sympathy and affection, humanity and philanthropy, hatred and revenge. Day and night regularly and constantly succeed each other, but no man in his senses would say that day is the cause of night, or night the cause of day. High tides and low tides regularly succeed each other twice every day, but it would be idle to pretend that high tide causes low tide, or that low tide causes high tide. We.must look to other things, outside of the succession of day and night, high tide and low tide, as the causes thereof. We must look to the forces of nature, which cause the motions and revolutions qf the earth and the heavenly bodies, as the real causes of the succession of day and nigqht. Every effect and change in the universe must be wrought by some cause-either by the power of mind, or by the forc2s of nature inherent in matter-operating as causes; but the condition of things must be such as to bring a cause or causes into operation. The attractive power of the sun illuminates the side of the earth turned toward it, and catses everything so operated upon and illuminated to operate directly upon the nerves of the eye, and cause the sensation of light; but the sun can produce such effects only upon one-half of the surface of the earth at the same time. To produce action, motion, and effects, there must be a cause, and such a condition of the cause and things to be operated upon, as to bring the cause into operation, before any effect can be produced. For example, sparks of fire sometimes escape through defective chimneys and stove pipes, lodge in the roof, floor, floor timbers, or other combustible Matter of or in buildings, set them on fire,and destroy them. In such cases the element offire is the cause, the active element and force which destroys the building-the defective chimney or stove pipe, and the combustible matter in UNIVERSAL ATTRACTION. I6I the vicinity of it, being the conditions which enable the cause to operate and produce the effect. The defect in the chimney or pipe is not the cause of the combustion, nor is the combustible matter which receives the spark the cause of it —for without fire in the chimnney or stove no sparks- could escape, and no combustion could take place; and yet, with the fire in the chimney or pipe, no such effects could take place without both of the conditions named. Fire cannot burn without combustible matter, nor can combustible, matter burn until fire comes into contact with it. The supposed defect in the chimney or pipe and the existence of combustible matter in the vicinity, are both necessary conditions-to bring the cause into operation-to enable the spark of fire to come into contact with something that will burn; and yet these conditions are both entirely distinct from the cause of the combustion. When man acts, the causes and the machinery of his action are still more numerous and complicatedincluding appetites and passions-as exciting causessometimes purposes and ends to be attained, instruments of action, and conditions or circumstances, as well as opportunities. When crimes are prompted and induced, or caused by a spirit of revenge, another element enters into the chain of causes-that is, provocation, family or national hatred, arising from some anterior cause-that operates, excites, and causes the spirit of revenge, which is the immediate cause of the crime. The forces of nature constitute the material causes of all the action and changes in the universe. Universal Attraction. That combinations and bodies, as well as atoms of matter, act upon each other by some mysterious force or power, which we call attraction —and do so at all distances, at great as well as at insensible distances, and even at the distance of hundreds of millions I62 UNIVERSAL ATTRACTION. of miles, is attested by the constant motion of the earth and the planets, in their respective orbits around the sun, and by all the phenomena of our solar system. The whole science of Astonomy is based upon the theory of universal attraction. The moon, though at a distance from the earth of nearly a quarter of million of miles, acts upon its waters with such force as to cause the tides of the ocean. The surface of the earth, and everything connected with the earth, above its surface, is drawn towards the centre of the earth by that mysterious force,which, in that mode of its action, we call gravity or gravitation. Everything around us denser than atmospheric air, when raised from the earth and left unsupported, falls immediately to the gronnd. The weight of all bodies and elements of ponderable matter, depends upon the force which we call gravity. The chemical affinities, by which the atoms of different elements of matter are drawn towards and to each other, until they unite and form a compound, constitute another mode of iction of the force of universal attraction. The powers of cohesion and adhesion are other modes in which the force of universal attraction acts. The power or force by which bodies at greater or less distances act upon the organs of sight of man and all animals, is but another mode in which the power or force of universal attraction acts. In every class of cases referred to, except cohesion and adhesion. the force of attraction acts at a distance from the bodies which exert it. The chemical affinities, by which atoms of matter are drawn towards each other and united, must act at some distance, until the union is formed; and then the force which holds them together is called the attraction of cohesion. How the force of attraction, inherent in matter, can exert an influence at a distance from its surface, is a mystery which man can never solve. -Like the origin of matter and its wonderful properties, the subject lies beyond the domain of human science —beyond the sphere of human conception, in the obscure regions of IMAGINARY ETHER. I63 the unknown and the unknowable. As we must content ourselves with the simple fact of the existence of matter, without capacity to determine its origin or mode of creation-and must content ourselves with such inferences as we can draw from natural phenomena and chemical experiments, of the properties and forces of matter, and their modes of action-so we must content ourselves with the knowledge of the simple fact of the existence and action of universal attraction, without capacity to determine how it exists, or how it acts. Sir Isaac Newton, in one of his letters to Bentley, says: " It is inconceivable that inanimate brute matter should, without the mediation of something else,which is not material, operate upon and affect other'matter without mutual contact, as it must do if gravitation, in the sense of Epicurus, be essential and inherent in it; and this is one reason why I desire you should not ascribe innate gravity to me That gravity should be innate, inherent, and essential to matter, so that one body may act upon another at a distance, through a vacuum; without the mediation of anything else, by and through which their action and forces may be conveyed from one to another, is to me so great an absurdity, that I believe no man who has in philosophical matters a competent faculty of thinking, can ever fall into it." Such were the views, and such the doubts and queries of one of the most distinguished philosophers which the world has ever produced. An Imaginary Elastic Medium, Called Ether. In the vain attempt to obviate the difficulties suggested by Newton, as to the cause of gravity and its mode of action, and to inquire into and understand what the limited faculties of man are incapable of understanding, it has been conceived that all space and the whole universe is pervaded by an elastic medium called ether, which is the cause of gravitation, and operates as the bond of union between the heavenly I64 IMAGINARY ETHER. bodies, as well as between the earth and its atmosphere, and all the elements and combinations of matter on or near the surface of the earth. What a magnificent theory! But how is the supposed elastic medium to operate? If it be inanimate matter, without intelligence and without will, it must act blindly, from its own inzate, inherent, atnd essentialp2roperties and.forces, as the inanimate brute matter operates, which is known to the chemist, and which our senses and intellect take cognizance of; and if its atoms or particles do not all touch each other,arind touch all the bodies and elements of matter in the universe, so as to leave no vacuum, the difficulties suggested by Newton, of the force of gravity acting at a distance, would still remain. The supposed elastic medium, if not a part of the Divine Spirit, and moved by the Divine Will, would have no properties,powers, or forces different fiom those which we can conceive inanimate and unintelligent matter to be endowed with; and hence, it would not solve the question of the action of bodies of matter upon each other at a distance, nor remove any of the difficulties involved in it. It would be as difficult to conceive how the supposed ether could act with such mysterious and wonderful powers, as it is to conceive how inanimate and unintelligent matter can act without such medium. The mystery would still remain. To assume that a subtle, elastic ether pervades all space, does not solve the mystery, nor in the least degree lessen it —unless you also assume that the supposed ether constitutes the animus mundi of the ancients —is the God of tile Pantheist-and constitutes the only force in the universe-constituting not only the force of gravity, but also the chemical affinities and forces, the power of cohesion, and the peculiar force of caloric, electricity, and magnetism. There is no basis but Pantheism upon which to found the assumed ether; and I cannot conceive how it can exist and exercise such various and mysterious powers, unless the Pantheistic system of theology be true. IMAGINARY ETHER. 165 If, in accordance with the views of some theological theorists, we were to suppose that all the action of what we call gravity and attraction,is produced by the direct act and agency of God; the mode of such action and the instrumentalities employed, would still be mysterious. The mode in which the Infinite Being acts, and the instrumentalities which he uses, are, and must be, mysterious to finite beings, and beyond their capacitv to understand or conceive. This may as well be admitted by scientists and philosophers, and when that is done, they need not worry their brains and minds to conceive imaginary mediums and instrumentalities, to account for the modes of action of gravity, and the various other forces included in the term attraction. So far as finite beings can see and understand, gravity, and all the forces included under the general terni attraction, are inherent properties of matter, which cause distant bodies to act upon and attract each other —by means whereof, every thing on and near the surface of the earth is drawn towards the centre of the earth, and the earth and the planets are kept in their orbits, and caused to move around the sun. Let us consider some of the familiar facts in relation to the action of gravity. A stone or rock rolled from the edge of a precipice or steep ledge, bounds down the side of the precipice with great velocity, leaping into the air from point to point, and continuing its course until it reaches the bottom, or some level ground. When apples and other fruits growing upon trees become ripe, the stems which attach them to the trees become weak, and they fall to the ground. What causes the descent of the stone in the one case, and the apples in the other? Can there be any reasonable doubt that the earth draws them by -the direct force of its power of attraction,operating upon thenm at a distance, and without actual contact? Can any other rational explanation be given of such phenomena? Is any other explanation consistent with chemical action? Does the assumption of the existence of an elastic me i66 IMAGINARY ETHER. dium of ether aid in solving the question? If such medium exists, and the earth's attractive power is exercised only upon the contiguous particles of ether,and they communicate a force from one set of particles to another, until a force reaches the stone or the apples, the earth itself would exercise no power over the stone or the apples; on the contrary, they would be influenced only by the force inherent in the contiguous ether. To suppose that the attractive force of the attenuated ether in contact with the stone and apples would be sufficient to cause their fall,is to make a supposition which violates the great cardinal principle of gravitation-that when two bodies mutually attract each other, the power which each exerts on the other is in proportion to the quantity of matter contained in it. The moon being less than one-sixtieth part as large as the earth, its motion is controlled by the attraction of the earth-so that it is carried around the earth nearly thirteen times each year, in its general course around the sun-its action upon the earth being comparatively small. In the supposed case of the stone and apples falling, if the earth exercised no direct force upon them, its force being exercised only on the elastic ether in contact with it-which communicates a force from atom to atom of the ether until the atoms of ether in contact with the stone and apples exerts an ethereal influence upon them, it will be perceived that the stone and apples are so much larger and denser than the attenuated ether, that it could exert no perceptible influence on them; on the contrary, they would control the ether, as the earth and sun jointly control the motion of the moon-and instead of falling to the ground, stones and apples would remain suspended in space. The supposed elastic ether is entirely too weak and feeble to do the work assigned to it. The August and September numbers, of the year I874, of the Catholic World, contains articles on "Matter," in which the ether theory is denied, and combated with numerous arguments, and its absurdi IMAGINARY ETHER. I67 ties pointed out. On page 585 it is said: "That attraction excludes material contact is quite evident, for attraction produces movement by causing the approach of one body to another; and it is evident that no approach will be possible if the bodies are already in immediate contact." Hence the conclusion is drawn (p. 587) "That distance is a necessary condition of the action of matter upon matter," and "that any material substance, which is any where by reason of its matter, has within itself a power prepared to act, where the substance itself is not present by its rmatter." On pages 59o and 59i it is said, "Some modern physicists hold that what we persist in calling universal attraction, is not sttraction, but only an ethereal pressure exercised on the heavenly bodies; * * * that the ether which surrounds and presses the earth must be denser on the hemisphere where there is night, than on that where there is day, because the former is more distant from the sun than the latter; and they infer that on the former hemisphere the pressure must be greater than on the latter; which brings them to the conclusion that the earth must move towards the sun with a velocity proportional to the difference between the two pressures. Such is the theory by which some modern thinkers tried to supplant universal attraction. We need not go far to show the utter absurdity of this rash conception, as the most common phenomena and the most elementary principles of mechanics supply us with abundant proofs of its falsity." In the conclusion of the article,referring to the ether theory, it is said, "It is strange, indeed, that a theory, so preposterous in. its assrumptions and so absurd in its consequences, can have found favor with scientific writers, in the full light of this nineteenth century?" Views of Prof. Grove, on the Ether Theory. Prof. W. R. Grove, of England, is one of the apostles of the mystical philosophy of heat, and the I68 IMAGINARY ETHER. mutual convertibility of the physical forces into each other; and yet he repudiates the ether theory, and bases the action of matter upon what he terms the dynamical theory of forces, motion and heat. In his preface to his work on "The Correlation *of Physical Forces," he says: "It appears to me that heat and light may be considered as affections; or, according to the undulatory theory, vibrations of matter itself, and not of a distinct ethereal fluid permeating it. These vibrations would be propagated, just as sound is propagated by vibrations of wood (or atmospheric air) or as waves by water. To my mind, all the consequences of the undulatory theory flow as easily from this, as from the hypothesis of a specific ether; to suppose which, namely, to suppose a fluid sui generis, and of extreme tenuity penetrating solid bodies, we must assume, first, the existence of the fluid itself; secondly, that bodies are without exception porous; thirdly, that these pores communicate; fourthly, that matter is limited in expansibility. None of these difficulties apply to the modifications of this theory, which I venture to propose; and no other difficulty applies to it, which does not equally apply to the received hypothesis." In the work referred to, the Professor, treating of electricity, says: " If, instead of being regarded as a fluid or imponderable matter, sui generis, electricity be regarded as the motion of an ether, equal difficulties are encountered. Assuming ether to pervade the pores of all bodies, is the ether a conductor or nonconductor? If the latter-that is, if the ether be incapable of transmitting the electrical wave —the ethereal hypothesis of electricity necessarily falls; but if the motion of the ether constitutes what we call conduction of electricity,then the most porous bodies, or those most permeable by the ether, should be the best conductors; but this is not the case. If, again, the metal and the air surrounding it are both pervaded by ether, why should the electrical wave affect the ether in the metal, and not stir that in the gas? To support an IMAGINARY ETHER. I69 ethe —eal hypothesis of electricity many additional and hardly reconcilable hypotheses must be imported." page 102. After giving (pages IO7 and Io8) cases of the action of electricity, he says: "' These cases afford an additional argument to those previously mentioned, of the particles of matter being effected by the forces of electricity and magnetism, in a way irreconcilable with the fluid or ethereal hypothesis.' Again he says, (p. 124):'" The transmission of electricity through long wires in preference to the air which surrounds them, and which must be at least equally pervaded by the ether, is irreconcilable with such a hypothesis." Again he says: "' The phenomena presented by heat, viewed, according to the dynamic theory, cannot be explained by the motion of an imponderable ether, but involve the molecular actions of ordinary ponderable matter. * * * * An objection that immediately occurs to. the mind in reference to the ethereal hypothesis of light is,that the most porous bodies are opaque; cork, charcoal, pumice stone, dried and moist wood, &c., all very porous and very light, are all opaque." —(p. I24 to I27.) Again, he says; " Ether is a most convenient medium for hypothesis; thus, if to account for a given phenomena the hypothesis requires that the ether be more elastic, it is said to be more elastic; if more dense, it is said to be more dense; * * * * and so on. The advocates of the ethereal hypothesis have this advantage, that the ether being hypothetical can have its characters modified or changed, without any possibility of disproof, either of its existence or modifications."-(p. I33.) The most conclusive evidence that the various phenomena of light are not produced by undulations of any such medium as the supposed ether, is the fact, that light moves in straight lines only, and does not pass through crooked, circular, or bent tubes or passages; whereas water and all fluids, air and all gases, 17C0 IMAGINARY ETHER. will pass through crooked and circular tubes and passages, as freely as through those that are straight. The ether hypothesis will soon be exploded, and regarded as an absurd heresy, and common sense people will express astonishment, that men of learning and science ever should have been under the influence of such delusion, as to receive the heresy as a scientific truth. But when persons ignore the evidence of their own senses or consciousness, disregard common sense and the common understanding of mankind, and wander in the mazes of scholastic theories, they have no true land-marks to guide them, and are soon lost in scholastic subtleties and sophistry. CHAPTER XII. THE NEW, OR MYSTICAL PHILOSOPHY-ITS ASSUMPTIONS AND ERRORS POINTED OUT, EXAMINED, AND DISCUSSED. The Mystical Philosofphy- What it Comprises. The two theories-first, that an elastic medium called ether,permeates all matter, and fills or permeates all space-and, second, that heat is only a mode of motion, constitute ihe two chief corner stones of the new system of philosophy; which seem to me so strange and mystical, that it may properly be called the mystical philosophy, or the mystical system of philosophy. It comprisesIst. A denial of the existence of any such principle or force as universal attraction-operating at a distance, upon which the whole science of astronomy is based, and substitutes in its place an imaginary ether,as the motive power which moves the earth and the planets around the sun-whether by attraction or repulsion, the advocates of the system are not agreed. 2d. It denies the existence of any such element as caloric, and denies also that heat, or the cause thereof, is material, or an element of matter, and insists that it is a mere mode of motion. 3d. It affirms the undulatory ether theory of light. 4th. The chemical theory of combustion. 5th. The chemical theory of organization, life, 172 MYSTICAL PHILOSOPHY. and mind-that life, mind, and thought, are the mere results of organization; and 6th. The dynamical, or mystical theory of forcethat the naturol forces are not inherent properties of matter, but an immaterial mystical agent, acting through the imaginary or supposed ether, independent of any matter known to the chemist; that heat, electricity, and magnetism, are like gravity-not elements of matter, but immaterial forces of nature; and that all the forces of nature, including light, are substantially one and the same force, and may be transmuted or changed, each into either of the other forces. It denies the existence of any vital organizing element of matter-forming the basis of life; ignores the existence of any such spiritual essence as intellect-forming the basis of conscience, intelligence and thought; and deduces the phenomena of life and mind, consciousness and thought, from the chemical and dynamical action of the forces of nature. The new philosophy is very nearly identical with the Pantheistic theory of the universe. The germ of the motion theory of heat originated with Count Rumford, the last part of the I8th century; some slight traces of the theory of an elastic medium, is of older date-but the new system of philosophy has been gradually developed and matured during the last fifty years, or since the year 1820, until it has become one of the most stupendous fabrics of assumption and sophistry ever presented to the human mind. A Vague and Indefinite Use of Words. In matters of science words should be used with great precision and accuracy, and in senses that are well understood and defined. They should not be used loosely and vaguely, in an indefinite and uncertain sense. Many words and phrases are used in the new and mystical philosophy, in senses that are indefinite and obscure, inconsistent with each other, and sometimes in a mystical sense. Among the words USE OF WORDS. 173 and phrases so used, are the following: heat and motion-mode and form-eforce and energy-immaterial forces-dynamical energy or force-dynamical cause or causes —mechanical force or forces-molecules, molecular force, and molecular action-ether and luminiferous ether-transformation of force, and conversion of force-evolution and development. The manner in which such words and phrases are used in books of science, serves to obscure the subject treated, rather than to throw light upon it. Abstract terms are often used as if they represented a force or power, independent of matter. The words heat and motion, force and power, cause or causation and energy, dynamical power and dynamical force, and some other words, are used in the NEW PHILOSOPHY in a mysterious and mystical sense-as if they were immaterial agencies —existing without substance and independent of matter. The words heat and light, electricity and magnetism, are used as representing one and the same mysterious agency or force, manifested under different circumstances, in different modes -each being convertible into either of the others. The most of the scientists of the mystical school assume that there is an elastic ether, sometimes called luminiferous ether, pervading all matter and all space, which they seem to regard either as the one great force of nature, manifested in different modes, or as the medium through and by which the immaterial agencies of nature act. But Prof. Grove discards the ether theory as an untenable hypothesis, and relies entirely upon the dynamical theory and dynamical forces as an immaterial agency, and the only active forces of nature. Heat, or Caloric, and its Action. Heat, or rather the cause of heat, (caloric) cannot be a mere mode of motion, for many reasons. Mere motion and the mode thereof, is of itself powerless. It is not matter, nor material, has not the force of mat3 174 HEAT-WHAT IS IT? ter, and is not, and cannot be, an efficient cause of action or change. Caloric is very different. It is so material in its character and properties, that it occupies space, and expands all bodies which it permeates. It is the great solvent, and the great stimulant of the universe. Neither combustion, chemical action, fermentation, vital action, vegetable growth and development, animal life anw growth, evaporation, nor even the motion of the atmosphere, can be originated or continued without it. It is radiated into the atmosphere, and can be felt as an independent substance, and carried in and by the winds hundreds of miles. It passes from one body to another, and can be accumulated and intensified by accumulation. It never ceases to exist in any body, or compound of matter, whether such body be in motion or at rest; but to accumulate it, and produce the greatest intensity of heat, as in a retort, or in the coal or metal in a retort, the thing in which it is accumulated must be at rest-and not in motion. Rapid motion is not consistent with much accumulation or great intensity of heat. Generally speaking, the greater the heat at or near the surface of the earth, the stiller the atmosphere. Though the simooms of the deserts of the Torrid zone are hot, the winds blowing from twenty to an hundred miles an hour in high latitudes, are generally cold. The temperature of the winds is never increased by their velocity, but depends upon the season of the year, and the direction _from which they come. If heat were a mere mode of motion, then a state of rest, the cessation of motion, would cause the instantaneous cessation and annihilation of all the heat produced by the motion of the moving body; and it would be impossible to accumulate heat to such a degree of intensity as to melt iron, or to produce great fires, and extensive conflagrations. Caloric and a few of the metals, are the only elements of the material world that were known to the:ancients. Caloric was known for thousands of years before any other element was known, except some of MOTION. I 75 the metals-when water and atmospheric air were both regarded as simple substances. It is more clearly discovered by the senses than any element known to the chemist, except some of the metals. It is the most powerful of all the elements of the material world-being the great solvent of nature. It permeates, expands, fuses and destroys every compouid of nature; and yet, the very existence of this most powerful, best known, of all elements, has been thrown into doubt, by a class of scientists. An obvious truth, that heat is caused by an element of nature, is denied; and a contrary proposition, that heat is a mere mode of motion, is affimed as true, and dignified with the title of a scientific truth-though it is based on assumptions which seem contrary to common sense, and supported by a course of artificial reasoning which appears mystical and sophistical. _Motion. Motion is not a force, power, or cause; but simply a condition of matter in a state of change-an eflect produced by some active force. Motion is a changeable and accidental condition of matter, and cannot exist independent of matter; while the cause of motion is the active force or power inherent in the matter itself-being as indestructible as are the atoms of matter. It is true that a body in motion will produce effects which a body at rest cannot do; but such effects are secondary, the first effect being the motion itself, which is produced by the inherent properties and forces of the body itself, and of other bodies and forces acting upon it, and co-operating with it —which properties and forces produce the secondary as well as the primary effects. Motion alone cannot produce any effect whatever. It cannot even develop heat, without friction, nor produce any of the phenomena usually produced by caloric. Motion not being a substance-not being material -not being matter, nor even an attribute of matter, 1 76 MOTION. but only a condition of matter in a state of change,the thing itself ceases to exist the moment the moving body ceases to move. It cannot be preserved for a single moment, and cannot be accumulated. Heat cannot be mere motion, for heat can be accumulated and is accumulated to an almost indefinite extent in blast furnaces, and in such fires as the great conflagration in Chicago, in i87r, and the great fire in Boston in I872. And when accumulated in furnaces, stoves, steam boilers and stones, heat can be preserved for many hours, after the combustion and consumption of the fuel which produced it has ceased. Again, if heat were mere motion, the degree of its intensity would necessarily depend upon the velocity of the moving body. How does that theory of heat agree with the fact that iron is heated in a furnace or forge fire, first to a brown heat, then to redness, and finally to a white heat, when the iron itself is at rest, and the furnace is also at rest. The velocity of the earth's motion on its axis and in its orbit, is the same at the 50oth degree of latitude in each hemisphere-whether the north or the south pole be inclined toward the sun. If the earth's motion be heat, and the great source and cause of heat upon its surface, why is it sometimes intensely hot as high as the 5oth degree of north latitude in summer, when the north pole is inclined toward the sun, and intensely cold at the same time at the south pole? If motion be heat, why is there perpetual snow on the mountain peaks of Mexico and South America in the torrid zone, when it is excessively hot in the neighboring valleys, within an hundred miles of such snow-clad peaks? Motion alone cannot generate matter, nor produce any change in matter. What is said in common parlance to be produced by motion, is in fact produced by one or more bodies in a state of change, and not by motion itself. Nor are he properties or forces of matter in any way changed by a state of motion. By the decomposition of a compound body, its elements are MOTION. 177set free to form new combinations; but the properties of those elements and the substance thereof, remain always the same, unchanged and unchangeable. Neither the decomposition of a compound, nor the combination of its elements with other elements of matter, can generate or develop any property, force or power, which did not previously exist in the elements themselves. This may be regarded as a selfevident truth. It must be true —unless something can be generated and produced from nothing. It is as utterly impossible for motion, or even the friction of two or more bodies to generate an element of matter, as it would be for mere space to produce such an effect. Bodies in motion may attract more strongly such mobile and subtle elements as caloric and electricity, than they do when at rest; and by violent friction may press out of them,and thereby develop such subtle elements as may be in them in a latent state, or in the surrounding atmosphere-but to suppose that motion and friction can generate an element of matter, or can generate a force, power, and property, like caloric or heat, which can melt iron, stone, and all earthly substances, and reduce them to fluids, seems like a logical impossibility, and an a)surdity. Mode. Prof. Tyndall and his school of scientists call heat a mode of motion-placing emphasis upon the word mode-as if it added great force to motion, and gave the phrase a meaning very different from the word motion alone; but he does not point out what that difference is. The word mode when used in its most precise and definite sense, is applied only to action and motion. Every action and every motion must have mode, and therefore the phrase mode of motion, without defining or describing the mode, has precisel) the same meaning as the word motion when used alone, and it has no other, broader or different meaning. I 78 MODE-FORM. The word mode does not express any force or power, and the manner in which it is used by Tyndall and his disciples, in connection with the word motion, as a definition of heat, throws no new light upon the subject, but tends to obscure in some minds, what has been well known for thousands of years. Fire and heat are too well understood by all persons of common sense, to need any new definition, new description, or scientific theory to illustrate it. It would be difficult to conceive a more preposterous idea than that involved in Prof. Tyndall's definition of heat-that it is a mere mode of motion, destitute of substance: Form. Form is an incident to substance, and bears the same relation to substance that mode does to motion. Every thing which has substance must have form also. Form is inherent in substance and inseparable from it; but the word form never can be properly applied to the active properties, or forces of matter. Form is not an active property of matter, is never a force, and can never act as a cause; and yet the disciples of the mystical philosophy often use the term in an indefinite and mysterious sense, as if it represented a force of nature. Force and Energy-Immaterial Force. The words force and energy are often used by writers in a mystical sense, as if force and energy could and do exist, independent of matter and of substance. What do they mean by immaterial force? Do they mean a force inherent in and exercised by a Pantheistic, or Divine Spirit; or what do they mean? The vague and indefinite use of such words only serve to cover as with a vail, the ignorance of the writer, and carry the appearance of wisdom, by shrouding the subject in mystery. FORCE. I79 Dynamical Energy-and Mechanical Force. What is meant by dynamical energy, as used by Tyndall, Grove and others? Is it one of the forces of nature which I have enumerated; and if so, which of them? Is it the force of gravity; or is it a chemical force, a magnetic force, an electric force, or the force of caloric or heat? Is it a physical force, pertaining to inanimate matter only,or does it pertain also to living organisms? The manner in which the phrase is often used only tends to involve the subject in obscurity. What is meant by mechanical forces, when applied to living organisms? All the mechanical powers, except the expansive power of steam, are based upon the force of gravity-to which the vital force acts antagonistically. Hence, it would seem that the phrase mechanical force has no proper application as an actual force, to either animal or vegetable organismsexcept that the matter composing them occupies space, has the power of resistance, and also the property or force of gravity; and yet the the terms are often used as if they constituted the chief motive power of animal organisms. Molecular Force, and Molecular Action. Molecular force, and molecular action, have been applied by writers to both animate and inanimate matter; and hence they do not mean that it is vital force. What do they mean? Do they mean anything different from the forces of nature-if so, what? What do writers mean by the word molecule, which has been much used of late, in physics? Do they mean atoms, or combinations and compounds of atoms; and if compounds, what kind of a compound forms a molecule; and what forces can molecules possess which are not possessed by the atoms of which they are composed? i80 CONVERSION OF FORCES. Transformation and Conversiou of Forces. Volumes have been written of late upon the correlation and conservation of forces. If the atoms of matter be indestructible and unchangeable, the properties and forces thereof must also be indestructible and unchangeable-from which the conservation of forces would result as a consequence, and it requires no long course of reasoning to prove it. But if the atoms and properties ot matter be unchangeable,which seems to be a self-evident truth, the simple forces of nature, resulting from those properties, must also be unchangeable-and hence the conversion of one force into another, as is assumed by writers of the mystical school, is an impossibility. The assumption of this convertibility, is based upon the further assumption, stated by Prof. Youmens, that heat, light, electricity, and magnetism, are not "subtle fluids with peculiar properties, but simply modes of motion in ordinary matter; forms of energy which are capable of mutual conversion." Such strange assumptions, not in harmony with common sense, need proof. They need something more than scholastic subtleties and sophistry, to support them; but there is nothing too absurd to be embraced by the human mind as truth, if it be presented in the garb, and dignified with the name, of religion, philosophy, or science. Prof. Tyndall is in the front rank of a school of science, which, in its interpretation of many of the phenomena of nature, ignores common sense and the common understanding of mankind, as unworthy of the consideration of men of science, and bases its reasoning upon mere assnrnptions, improbable hypotheses, and fanciful theories. Evolution and Development. The subject of evolution and development was examined in the last chapter, and they were shown to be a:process —not a force, power, nor cause of action; and that they need a moving power to originate them, IMAGINARY ETHER. I 8 I and carry them on. They are often used as if they constituted a mysterious force or power, by which the animal creation, as well as varieties thereof, were originally brought into existence. The Imaginary Ether. The subject of ether was examined in the last chapter. No word was ever used by man in so many inconsistent and conflicting senses as that of either. It is intended to represent the hypothesis of an elastic medium permeating all matter and all space; and the most marvelous and conflicting forces and powers are attributed to it. It is called elastic ether, when power is attributed to it, to act as a substitute for universal attraction, to move the earth and the planets, and all the heavenly bodies. When it is said to convey the sensation of light by its waves,it is called luminiferous ether. It is supposed to radiate heat and light in contrary directions, and in all directions at the same instant of time-to produce motion in solid bodies-to be the cause of intense heat of red-hot iron, and to excite no heat at all in ice. What is very marvelous in its action is, that it brings to the organs of sight images of all the objects in front of the eye. Whether it be a self-acting power, or is dependent on a Pantheistic Spirit to move it, has not been explained by its advocates. If it be self-acting, it is impossible to conceive how it acts, unless it is in fact, a Pantheistic Spirit. The defects in its luminiferous characteristics are, that they will not act, except under the influence of the sun's attraction, or the attraction of some other luminous body, or of a blaze of fire. On the side of the earth opposite to the sun the ether is opaque, and leaves us in darkness. Unlike other gases and fluids, it will not pass through crooked tubes and passages; which raises the suspicion that it is imaginary only, and does not, in fact, exist. I82 RADIATION OF HEAT. Accumulation and Radiation of Heat. That heat is radiated from a burning fire, from a heated stove, from other super-heated bodies in which it is accumulated, and also from steam, is a fact so well attested by our senses, and by the common sense of mankind, that no one will deny it. How can mere motion be accumulated and radiated as heat, in accordance with the motion theory of heat, and thereby produce upon the senses the effect of heat? To suppose that motion can be radiated from a fire or heated stove, and produce the sensation of heat, without the emission of any substance which is the element or cause of heat,' would be a self-evident absurdity. If anything is radiated that can excite the sensation of heat, it must be matter in motion; and if matter be radiated, whether you call it heat, caloric, or fire, the thing is the same, and the motion theory of heat must be false. If motion be heat, then the degree and intensity of heat must depend upon the velocity of motion, and upon nothing else; and a state of rest must be the entire absence of any heat whatever-that is, a condition of rest must be a state of the most intense cold, and there can be no such thing as latent heat. The advo. cates of that theory have not considered the consequences which would flow from its principles. Heat a ball of iron in a puddling furnace to a white heat, and the attraction of cohesion will still hold the particles firmly together, and keep them at rest, until the heat is raised to an intensity of about 3,000 degrees Fahrenheit, before it will melt and run. How is it possible to conceive that the fuel with which the furnace is heated, is decomposed and consumed by motion only,converted into motion,and the motion communicated to the iron, and the iron heated by the motion, when the fuel and the iron itself, and every part of it, is at rest? How could we be sensible of the heat of red-hot iron, or of a heated stove, some inches dis HEAT BY FRICTION. I83 tant from us, unless atoms of heat radiate from the iron to the skin, and thus excite the sensation of feeling? We cannot perceive that there is any more motion in a red-hot ball of iron in a puddling furnace, than there is in a body of ice upon the surface of a lake or river; and it is contrary to common sense to suppose that there is any motion in either. The motion theory of heat involves the self-evident fallacy, that theparticles of a red-hot ball or bar of iron are, and must be, in violent motion, while the ball or bar itself, as a whole, is at rest; and yet, fallacious as it is, it has been stated as a scientific truth, by a leading writer and advocate of the theory, (Balfour Stewart). Verily, what has been dignified with the name of Science, has run into strange mysticisms and absurdities! Does the thermometer measure the motion of the atmosphere, or the degree of heat arising from an element of matter, which causes the sensation of heat? If the heat of the atmosphere depended upon its motion, and was increased by increase of motion, it would be colder in ravines and valleys, than upon elevated plains, and upon the sides and tops of mountains; which is directly contrary to the fact. Development of Heat by Priction. That friction developes heat is a well-known fact. It is shown most frequently in the journal boxes of railroad cars, which are kept constantly oiled, to avoid heating. I say that friction developes heat-it cannot create heat, nor call it into existence de novo; nor can motion alone, without friction, even develop heat. To suppose that motion or friction can call heat into existence de novo, create it out of nothing, or increase the quantity of heat in the universe, would be an absurdity. The question then arises, where does the heat produced by friction come from? As it is difficult, and perhaps impossible, to answer that question to the sat I84 HEAT BY PRICTION. isfaction of all, it becomes necessary to study the process of friction, and the nature of heat, as the only means of solving the difficulty. As to the nature of heat there are two theories: Ist, That heat is a subtle,volatile, imponderable fluid — one of the elementary substances of nature, which chemists have called caloric,-having certain affinities for every element of matter, and penetrating and pervading all the compounds of the world, and yet having no such affinity for any element as to form a chemical compound, or combination with it. 2d, The other-the new theory is, that heat is not matter-not substance-but only motion, or a mode of motion, without substance or properties; for it can have no properties without substance, and yet it produces real and sensible effects. The only argument that has been presented against the material theory of heat is this-heat is constantly produced by the friction of the same things, as long as the friction continues, and it is said that if it were matter pressed out of the things rubbed together, the supply would soon be exhausted, and the fact that it is not exhausted but continues to be produced as long as the friction is continued, is argued as proof that heat cannot be material. As matter in motion communicates its motion to some extent to other bodies with which it comes in contact, it is argued that the heat produced by friction cannot be rationally accounted for as matter, and must be regarded as motion only. Such are the slender foundations upon which the whole fabric of the motion theory of heat is based. If the theory were true, the heat would be confined, as the motion is, to the bodies which come in contact and produce the friction; and no sensible effects could be produced or felt beyond the surface of these bodies and the things coming in contact with them; which is not in accordance with the fact; for we know that heat is radiated and produces sensible effects at various distances from the radiating source-and I cannot conceive how any thing, not material, can be radiated HEAT BY FRICTION. 185 and produce such effects. Again, heat expands all substances which it penetrates-ind that fact furnishes conclusive evidence that it occupies space, and has some of the properties of ponderable matter. As heat produced by friction must be merely developed and accumulated at the point of friction, and cannot be thereby created or called into existence, it would seem that it must be pressed out of the surfaces of the things rubbed together; or 2d, come from and be pressed out of the atmosphere which is constantly drawn in between the bodies revolving rapidly in contact; or, thirdly, it must be strongly attracted by the bodies in motion, and caused to accumulate at the point of contact and friction, and thus aid in furnishing the supply of caloric developed by friction. So far as I can understand the subject,these are the three sources which furnish the supply of caloric or heat developed by friction. There are some indications, I think, that matter in motion attracts both caloric and electricity more strongly than matter at rest. If any heatbe developed by motion alone-without friction-it must be because matter in motion attracts caloric more strongly than matter does when in a state of rest. It would be difficult to assign any other rational cause, to account for the fact. Combustion is a calorific process, and not a process of motion, nor of friction; though ignition and combustion may originate with caloric developed by friction. How can the advocates of the motion theory of heat explain, in accordance with their theory, the development of heat by combustion? A very small amount of heat is developed by the friction of the machinery of mills and factories, and locomotive engines; but it cannot be made available and utilized by man —and not an hundredth part as much is so developed, as by the combustion of the fuel used in making the steam required to propel the machinery of mills operated by steam. The combustion of fuel by caloric furnishes, not only all the heat I 86 EVIDENCE. that ever was made available to produce steam, to be used as a moti ve power, but also all that is used to warm factories and workshops, dwelling houses and other buildings-to warm the people in cold weather, and to cook their food at all seasons of the year. We must and do look to combustion, not to motion nor friction, as the great source of heat which can be made available, either as a motive power, for mechanical purposes, or for warming our buildings. Though a very little heat may be developed by friction, none wvas ever developed by motion alone. Sufficient caloric can be developed by friction to ignite gun-powder, light a friction match, or kindle a fire with tinder, or with very dry and combustible materials; but not sufficient to heat an iron furnace to so high a temperature as to melt iron-stone, anc the limestone used to flux it. Evidence. The human mind depends upon evidence, upon which it forms its opinions; and must depend mostly upon the organs of sense, to furnish it evidence, and upon its understanding to interpret the evidence; and when men disregard the evidence of their own se ses, and the common sense and common understanding of mankind,and rely upon mere assumptions and fanciful theories, as the basis of their reasoning, they are in the condition of a mariner at sea in cloudy weather in the olden time, without a compass with which to guide the movements of his vessel. Difficult and doubtful questions in matters of science, as well as in courts of justice, should be determined by the weight of evidence. Apply that rule to the motion theory of heat, and weigh in a balance the great truths of the generation of heat by combustion in great conflagrations, and the destructive effects of heat so generated, with the little obscure facts of the generation of heat by firiction, and the latter will at once kick the beam. How trifling and insignificant the latter appear, when compared with the former! BOOKS ON SCIENCE. I87 What an overwhelming balance of evidence in favor of the old theory, offthe generation of heat by the calorific process of combustion! The great and striking facts of the conflagration of cities and forests by the calorific process of combustion, are disregarded by the advocates of the motion theory of heat, and not taken into the account by them, when reasoning in relation to the origin and cause of heat; and the obscure and insignificant fact,that some degree of heat may be developed by friction, is made the sole basis of their reasoning upon the subject. They never allude to the generation of heat by combustion; and their writings do not indicate that they are acquainted with any such phenomena. Professors Tyndall, Huxley, and Maudsly, are at the head of the school of materialists, in England. In their reasoning to establish the doctrines of materialism, they ignore, or overlook, thefact and phenomena of consciousness, the distinction between the physical effects made upon the organs of sense and the cognitions of such effects by the mind-and also the evidences, which such cognitions, and the consciousness thereof, furnish of an intellectital element or principle, in man. They seem to be unacquainted with, or not to understand,the great principles of intellectual science. Books on Chemistry and Physical Science. Great efforts have been made during the last twenty years, by the advocates of the ether theory and the motion theory of heat, to infuse their doctrines into the public mind, into schools, and into books of science-and more especially into works on chemistry and physical science. They seem to have had almost the entire control for many years of the British Association, and have used it as a means of propagating their doctrines, and infusing them into the popular as well as the scientific mind of the United Kingdom; but, as yet, they have had no very great success in the United States. The reception with which such doc x88 BOOKS ON SCIENCE. trines have met with in Great Britain, and the admistion they have gained into books on science published in that country, have not been without their influence here. Our authors and scientific men, however, have very generally received and treated them as uncertain and doubtful speculative theories which do not command their assent; but being supported by so many leading scientists abroad, they seem unwilling to take a bold stand against them, and to condemn them as fanciful and untenable. All our authors on chemistry of any standing, merely state the motion theory of heat as a hypothesis, and present the subject in language and arguments, and use illustrations, which are consistent only with the theory, that heat is caused by an element of matter. It is so with American books on Physics and Astronomy; in which these subjects are treated as if the world and the universe were governed by the force of unzversal attraction, and very liftle notice is taken of the imaginary ether. Prof. Wilson, of Edinburgh, in his work on Inorganic Chemistry, has left out caloric, electricity and magnetism, as not elements of matter; though they are all treated in American works as imponderable matter, and the most active of all the elements of the material world. The professor seems to have overlooked the fact, that the chemical affinities will not act without the stimulating influence of heat. His work presents chemistry emasculated. To perform experiments in chemistry successfully, it requires in the laboratory or room where they are performed, a temperature of about 70 degrees, to facilitate chemical action. Fermentation will not take place when the temperature is below 40, and will not progress very rapidly with a temperature below 70. The chemist can do nothing without the constant aid and stimulating influence of caloric, and he must have it in much larger quantities than can be furnished by friction. All the heat produced by friction in the Island of Great Britain would not be sufficient to warm properly the laboratory of one of her great Universities.
