The Polai The United States steamer Polaris, a fore- topsail scboouer of tbreo luuidred and eigbty- seveu tons, commaiuled by tbe late 0. F. Hall, left the Washington uavy-yard at 12'' 30"" p. ni., Jnne 10, 1S71, bonud for Brooklyn, where she dropped anchor June 1-1 at 7'' 30™ a. m. After having been made ready for sea she left this port the evening of the 29th, making New London Harbor the following morning, where she remained nntil July 3. Making sail at day-break she left the harbor, and, after having passed Eave Eock at 5'' 20'", shaped her coarse ^^ for Now Foundland, reaching St. John's Har- -r;^S bor near noon July 11, where she remained _^_"^ till the 19th. -^^^—^^ Thefirst port made in Greenland was Fiskor- naes, in latitude 03° 5' N., longitude 55° 32'. 3 \V., where the vessel dropped anchor in the afternoon of July 27, and remained till day-break July 29. Goastingaloug the steep cliffs, Holsteinburg, in latitude 66° 57' N., longitude o3^ o3'.7 W., was reached on July 31 at 10'' a. ni. Thence she started agaiu August 3 at 2'' p. ni., arriving, 21 hours later, at Goodhavu, in latitnde 69° 14:'.7 N., longitude 53^ 31' ^V. Here she had to await the arrival of the United States steamer Congress, a supply-vessel dispatched from New York. Having coaled up and taken the stores on board, she left Goodhava August 13 at 2" p. m. and dropped anchor at Upernivik, in latitude 72'= 46' N., longitude 56° 2' W., the following day at 11"^ 30"" p. m. She put to sea agaiu ou the 21st at 8'' 30'" p. m., reached Kingigtok Island at 11'' p. m., where she stopped for two hour^, and then she made her way to Tassiussak, latitude 73^ 21' N., longitude 50° 5'.7 W., dropi)ing anchor at 5'' 30'" a. m. ou the 22d. Leaving this place, the most northern settlement of white men ou the globe, at 2'' 15'" p. m. ou the 21:th, her course was shaped to the westward across Melville Bay. With the exception of a number of bergs scarcely any ice was met with, and at noon the uoxt day she found lierself in latitude 75'^ 56' N., longitude 09° 20'. 5 W., passing Conical Eock at a distance of about 13 miles at about 1'' p. m. aud Cape Dudley Digges one hour later. At eight in the evening Granville Bay was opened, aud at 9'' the vessel was surrounded by broken ice, through which she steamed without any difiiculty, passing Fitz Clarence Eock at IL'' 10'". Her position at noon ou the 27th of August was latitude 77- 51^ N., loiigitude 73° 11' W., and at 3'' p. ni . she doubled Cape Alexander, thus eutering Smith Sound. At 4'' 37'" Port Foulke was passed, at 0'' 50™ Cairn Point, aud at eight in the evening she fouud herself abreast of Van Eensselaer Harbor, shaping her course more to the northward and heading for CapeFrazer, a prominent land- mark ou the east coast of Griunell Land, which was doubled at 8'' 30"' a. m. August 2S, after a boat had landed to examine a sm.all bight in the coast. Her position on the same day at noon was latitude 80=^3' N., longitude 69° 28' W. Half an hour later Cape Norton Shaw, tlie south cape of Scoresby Bay, was sighted, and at 2'' 30'" she doubled Cape McClintock. Following the trend of the coast at an average distauc^e of from 8 to 10 miles she passed between Hans Island, latitude 4 HYDROGEAPHY. 80° 48' N., aud the main land at V2" 30'" a. m., August 29. As a dense fog was settling, the vessel was made fast to an ice-floe at about 8"^ a. ip., and when it began to clear toward noon she was cast off again, A meridian altitude of the sun placed her in latitude 81° 20' N. (longitude 64° 34' W.), which was the northernmost position determined astronomically at sea. From here Eobeson Channel appeared to be land-locked toward the north, but steaming on for about 5 miles the land toward the east and west began to recede, aud the channel was opened again. The atmos- phere being most of the time hazy or obscured by dense fog, the vessel steamed north at an aver- age speed of about 6 knots, keeping somewhat nearer to the east coast of the channel than to the west coast, and passing but little ice. As the fog grew denser and denser, and as considerable ice appeared, she was made fast to an ice-field about C miles in length at 9'' 35"' a. m. August 30, where she remained till 7'' 15'" in the evening. At 8'' 55" a boat crossed over to a little bay, now known as Eepulse Harbor, but was prevented from landing by the swift tidal current. As it was growing thicker the vessel was moored to a floe at 11'' 30'" p. m., getting under way once more at C' a. m., on the 31st. At 7'" 50" she had to be made fast again on account of fog, and when it cleared toward 9 o'clock she was under steam again. In the course of the afternoon another attempt was made to land at Eepulse Harbor, which proved more successful ; but as the little bight was filled with ice, and as it was open to the north winds, it was not considered to be fit for an anchorage. Since the pack north of Eepulse Harbor apparently stretched across the channel, the vessel was headed west, when she found herself in latitude 82° 16' N., longitude 00° 3' W., with the intention to attempt to get north along the coast of Griunell Land. Dense fog prevailing after 5 o'clock, she was made fast to a floe at 5'' 30", where she had to remain till 9'' 25" the next morning (September l),but scarcely had she been under way for 35 minutes when it grew thick again, and she had to be tied up once more, getting beset a short time afterward when the tide began to run flood. It continued to be more or less foggy until the evening of September 4, the vessel drifting apparently south during the whole time she was made fast to the floe. When it cleared, at about 8'' p. m., the remainder of theprovisions that had been previously lauded on the floe was taken on board again ; the vessel was cast off at 8^ 45'" and stood in for the east coast of the channel. At 12'' 30" a. m., September 4, she anchored in Polaris Bay, in latitude 81° 36'.4 N., longitude 02° 15' W., in thirteen fathoms of water, under the protection of a large berg and some grounded ice, named Thank God Harbor, where she was prepared for winter-quarters. As a place of such character can scarcely be termed a harbor, since the iceberg, named Providence Berg, broke to pieces under our own eyes, and as the fragments are very likely dissipated by this time, we are perforce compelled to adopt the name Polaris Bay as the only one applicable to the permanent features of the locality. A heavy gale from the northeast broke the ice on November 20, and, setting it adrift, the ves- sel swung to her anchor and against the berg in question, which latter, in the course of the wi)itor, was pressed farther and farther toward the shore. The Polaris, lying between the two and resting on a projecting tongue of the berg, heeled over at every low tide, sometimes as much as thirty degrees. The perpetual strain thus produced started her stem aud sprang a kak, which crippled all further progress of the expedition. During the latter part of June, 1872, the Polaris was sawed out and bore up for home August 12. In making her way through Kennedy Channel she got beset three days later, and drifting south to about latitude 8° 1' N., longitude 75° W., the ice round her suddenly parted during the night of October 15. While iq, this rather precarious position, a portion of her crew and most of her provisions were landed on the floe, to which she was moored. Under the combined influence of a strong southwest gale and a swift tidal current she parted her hawsers aud got separated from the portion of the crew that had been landed on the floe. The following morning she found herself north of her previous position, almost abreast of Life-boat Cove, where she was beaclied, in latitude 78° 23'.4 N., longitude 72o 51' W. In the spring of 1873 two boats were built of a por- tion of her timber, and leaving Polaris House June 3 the fourteen survivors were picked up by the Scotch whaling-ship Eavenscraig on the 23d in the vicinity of Cape York. After having beeii able to get clear of the ice of Melville Bay, the Eavenscraig crossed over to the west side of Baffin Bay, and in steaming through Lancaster Sound she fell in with the whaling-ship Arctic, from Dun-- CONDITION OF THE ICE. 5 dee, on July 7. A portion of the officers and crew of the Pohiris was transferred to Captain Adams's vessel, and afterward, when Captain Allen met the Intrepid, the officer in command of the latter kindly took another portion on board. The track of the Arctic, as far as it refers to the meteorological observations taken on board of this vessel, is laid down on the map accom- panying this volume. CONDITION OF THE ICE. A critical examination of the history of arctic exploration demonstrates the fact that the scope of the different discoveries made by means of vessels is in inverse proportion to the extent of the ice toward the region of departure, while that of sledge-traveling is governed almost solely by the condition of the ice, whether smooth or hummocky, stationary or drifting, compact or intersected by lanes of open water. It will furthermore be seen that the extent of the ice is not only subject to great changes daring the different seasons of one and the same year, but that it also varies in different years, according to the normal or anomalous march of the temperature of the lo- cality in question, to the direction of the prevailing winds in the vicinity, and to other influences • only partly known, and whose study would well repay for the time spent in their investigation. As we propose to give some results relating to this subject in the secoud volume of this publi- cation, where we shall dwell more in detail on the glacial system of Greenland, and of the arctic region in general, we shall limit ourselves here to the observations made during the expedition. In steaming north, after having left Tassiussak, the first pack was met with between 11'' and 12'' p. m., August 27, in about latitude 79° 3' N., longitude 72° W., stretching apparently across the sound. Following a lead, the vessel soon found herself in tolerably clear water, extend- ing along the coast of G-rinnell Land. After having passed the eightieth parallel the quantity of ice diminished, and but very few bergs were seen north of this latitude. Duriug the forenoon of August 20 some old floes made their appearance, to one of which the vessel w;is made fast for sev- eral hours on account of dense fog. Having been unmoored, she steamed north again, meeting- larger quantities of ice only occasionally, till she found herself north of latitude 82°, when she IVU in with heavy fields and high hummocks, intersected by minor lanes of water, and stretching across Eobeson Channel near- latitude 82° 16' N. From the deck of the vessel the barrier appeared more or less solid, but dense clouds of frost-smoke hung to the north of it, and from the crow's- nest a considerable body of open water could be seen. As it seems, Eobeson Channel, Hall's Basin, Kennedy Channel, Smith Sound, and Smith Strait are never entirely frozen over ; at least, it was always possible to detect open water in one or the other direction, both during our stay at Polaris Bay and at Polaris House. If we take tlie prevailing direction and force of the wind into consideration, and if we relnember that the different channels above mentioned are narrow, and, comparatively speaking, very deep, thus giving occa- sion to a swift tidal current, we can scarcely expect anything else. During the winter and spring of 1871-72 the only stationary ice near our winter-quarters was found along the shore, extending in a narrow belt from a few miles north of Cape Lupton, along the shores of Polaris Bay, to the mouth of Petermann's Fjord, and growing very hummocky near Cape Lucie Marie. South of Cape Morton, along the northwest coast of Petermann's Peninsula, it was found a little smoother in April, 1872, although intersecteil by lanes of water, while there was scarcely an ice-foot along John Brown Coast, and a traveling party, trying to reach Cape Constitution, was stopped by opeu water, and had to return, xis far as the observations made at Polaris Bay and Newman Bay go, the ice in the channel was adrift during the greatest portion of the time ; it was stationary only on a few occasions, during March, when the temperature was low, and when there was not much wind. Owing to the combined action of currents and winds, the ice forming in deep channels, flanked by steep shores, will always be found hummocky; and, indeed, that of Eobeson Channel and Hall's Basin was of the worst description. It was rougher than that of Smith Straits, the bad condition of which prevents the natives living near Cape Alexander from crossing the strait, scarcely 30 miles wide, and from communicating with the Eskimos inhabitating the region of Bllesmere Land, near Cape Isabella. It would lead us too far to give a detailed account of the condition of the ice during the time spent at the winter-quarters of the expedition. It will be sufficient to state that, during spring 6 HYDROGEAPHY. and summer of 1872, the sea ia Hall's Basiu and Eobeson Channel was in such a condition that, during the navigable season, the lanes of open water intersecting the ice were scarcely wide enough to permit a boat to be launched, while they were too numerous and the ice too rough to encourage sledge-traveling. In Hall's Basin the drift of the ice was in most instances southerly, accelerated by northeast winds and the flood-tide, which runs stronger than the ebb. The influence of the latter is less marked, and it was only wheu the returning ebb was accompanied by southerly winds that the ice drifted with the same velocity in a northerly direction as in the opposite one. During the stay of the boat-party at Newman's Bay the prevailing direction of the drift was likewise southerly, with the exception of a few occasions during the time of spring-tides, when a slow motion in the opposite direction could be noticed for a few hours at a time. • In a number of instances a strong westerly set was observed during the latter part of June and during July. While it was apparently calm, the ice could be seen to drift in great quantities from Polaris Bay to the coast of Grinnell Land, disappearing, as it seemed, in Lady Franklin Bay. As the set was so strong, and as the same ice was never seen to return, these observations led to the supposition that the bay in question was actually a strait. This view is supported by the observations made from the height of Polaris promontory, whence Mount Grinnell could be seen to be isolated from the main land, looking like an island, behind which an ice-horizon could plainly be distinguished. During the latter part of the summer of 1872 the condition of the ice was less favorable to navigation than during the preceding year. As stated before, the Polaris, when on her way home, was beset in Kennedy Channel, and drifted out of Smith Strait. From the 16th of August till the- middleof September lanes of open water of greater or less extent could be noticed almost daily along the coast of Grinnell Land, but it was impossible to reach them with the vessel. The pres- ence of open water along the west coast of a channel swept by a southerly current appears to be rather abnormal, as, according to theory, we might reasonably expect the contrary. The observa- tions on hand that might throw some light on this subject are, unfortunately, too few to enable us to ofier an explanation, but we shall see hereafter that the open water cannot have been pro- duced by high temperatures of the sea, as the latter were never much above the freezing-jjoint. The only possible assumption we can make is that the depth of the water, along the coast is more considerable than in the middle of the channel. In this manner the current would attain a greater velocity near the shore. It would carry the ice south as far as Cape Frazer, where the coast takes a more westerly trend, and where an accumulation along the shore is prevented by causes that are too obvious to be dwelt upon. We shall now consider in brief the condition of the ice in Smith Sound, based on observations made during our stay at Polaris House, from October, 1872, till June, 1873. A glance at the map accompanying this volume will show that the position of our second winter-quarters is but a few miles north of Port Foulke, the harbor of the Hayes expedition in 1860 and 1861, and the state of the ice in our case was very similar to that observed by Hayes ten years before; Smith Strait and a portion of Smith Sound being partly open during the greater portion of the winter and spring. If we are justified iu drawing conclusions in regard to the state of the ice in Kennedy Channel, or perhaps Hall's. Basin, from the motion of the ice in Smith Sound, we might judge that there must have existed a solid barrier stretching somewhere across one of these straits, as with scarcely any exception southerly winds would block the sound while northeasters would produce much open water. If this barrier did not exist, then the areaof ice carried north by the southerly (mostly southwest) winds must have either been greater at the time than the area of open water, or we might suppose that the winds north of Smith Sound blew from such a direction at the time as to counteract the influence of the southwest winds, under the force of which the ice drifted north. The open water found by Hayes during 1860 and 1801. was attributed by Petermauu * to the influence of the Gulf Stream; but we shall demonstrate hereafter that there is nothing whatever to support this view; that there is not the slightest trace of a warm current in the vicinity of Smith Sound; infact, that theonly permanent current existing there is setting south. Anycurrentsin the opposite direction, as mentioned by luglefield and others, are nierely produced by the flood- » Dr. A. Petermana : Das Noerdliohste Land der Ei-,le. Petermauu's Geogr. Mittheiluugeii, April, 1867, p^Ise^ CONDITION OF THE ICE. 7 tide, or perhaps by the difference that might exist at certain times between the specific gravity of water of Baffin Bay and that of Smith Sound. Before going any further we false occasion to repeat that the open water found in Smith Sound and north of this region is solely due to the effect of the winds and to the considerable depth of the narrow channels, giving origin to swift tidal currents. Had the meteorological observations made by the Hayes expedition been published when Peter- niann wrote the paper alluded to, the learned geographer would never have been tempted to show that the Gulf Stream sweeps the eastern shores of Smith Sound. It only remains now to give a short descri]jtion of the ice as found during the journey of the boat- party from Polaris House to Melville Bay. At the same time we think it advisable to dwell awhile on our observations made in regard to this subject in Lancaster Sound and vicinity, when on board the Arctic. The latter can be done very briefly, as the bihourly meteorological observa- tions made on board that vessel (compare the chapter " Meteorological Observations taken at Sea," p. 24) contain all the details that can be desired. When the boats left Polaris House June 3, 1873, they coasted at a distance of fronP 1 to 4 miles from the shore in clear water, meeting floating hummocks only occasionally, although the pack was in sight nearly all the time to the west. In regard to the condition of the latter, it is scarcely possible to pass any opinion, as ice sighted from a distance may appear as a sftlid barrier, while in reality it may be intersected by numerous lanes of open water, through which vessels can pass without any difficulty. Arriving at Cape Saumarez the solid land-floe was met with stretching in the meridian of this cape almost as far south as Northumberland Island. To the northwest of this island and of Hakluyt Island, a considerable pack had accumulated, through which the boats had to force their way in order to effect a landing on Hakluyt. Owing to the ice that blocked the strait running about northeast and southwest between these two islands, and to the pack that had accumulated to the south of them, the progress was very slow, and the boats were detained from the evening of June 4 until the morning of the 12th, when the ice dispersed. Between 8'' and 9^^ p. m. of this day Blackwood Point was reached, the boats meeting more or less loose ice during the whole of their passage, the most being encountered off Whale Sound, which was still covered by the solid floe, which stretchccl from a little north of Cape Parry along the shore and across Booth Sound to Blackwood Point. For about 8 miles South of this latter locality the coast was perfectly clear of ice, beyond which the fast land-floe was encountered stretching to the north westernmost extremity of Sounders Island and then in the direction of the meridian to the eastern portion of the north coast of Wolstenholme Island, while Dalrymple Eock was accessible. The floe appeared again at the southeast point of Wolstenholme, stretching southwest to about longitude 72° 5'. As the boats' track from Wolsten- holme Island to Cape York led always along the margin of the land-floe, a glance at the map will show how far the latter, which was very level, extended from the coast. Concerning the region of Lancaster Sound and vicinity, the season of 1873 must be termed a very favorable one to navigation. During July and the first half of August there was scarcely enough ice in Lancaster Sound to prevent a vessel from sailing anywhere between longitudes 80° and 90° W. The only unbroken floe-ice met with stretched across the month of Admiralty Inlet, while Prince Regent Inlet was open enough to permit the Arctic almost to reach latitude 72° N. When off Pond's Inlet, July 14 and 15, the fast land-floe could be noticed to extend from a short dis- tance south of Cape Burney to Cape Bowen ; but we learned afterward that some vessels of the whaling-fleet found the mouth of the inlet clear at the beginning of August. On the 18th of this month the Arctic was in latitude 72° 43' N., longitude 69° 24' W., working south through more or less ice, a short distance east from the land-floe, which extended from Cape Adair to Agnes Mon- ument in the shape of a belt, from 8 to 15 miles wide on the average. The river Clyde seemed to be open, but the floe was met with again at Cape Hewett, extending along the whole coast to a short distance south of Cape Kater. On the 25th the vessel steamed north through loose ice until the 30th, and when in latitude 71° 32' N., longitude 66° W., her course was shaped westerly; she had to force her way through heavy ice, gaining the open water at about noon the next day. The last ice seen during the rest of the passage was a huge berg met with at midnight of the 31st in about latitude 70o. 5 N., longitude 61°. 3 W. 8 ^ HYDEOGEAPHY. DENSITY AND TEMPERATURE OP THE SEA-WATER AND EEMARJiS ON CDEEENTS. Density and tempemiure.-Froui the day the expedition left the United States a series of obser- vations was begun to determine the density of the sea, and, in connection with these observations, the temperature of the water was measured likewise. The observations in question were taken more frequently than the meteorological observations proper, and were made at more or less irregu- lar intervals, according to the opportunities offered. After having crossed the arctic circle, tne density of the water was determined at least every other hour, and when near the ice or among the same, or when the vessel crossed alternate bands of cold and warm water, the observations were taken more frequently, sometimes as often as every ten minutes. The instruments used were very delicate hydrometers, made expressly for the expedition by Mr. Tagliabue, of New York. They were graduated from 0.990 to 1.050, giving direct indications to the third decimal, and as the length of each division was about 0.35 centimeters, the fourth deci- mal «ould easily be estimated with accuracy. The readings were taken on board the vessel, and although the cylinder into which the hydrometer was immersed, when in use, was not suspended on gimbals, as might have been done, the accuracy of the readings was scarcely affected, as there is usually byt little swell among the ice. In order to eliminate the iniiuence of capilarity, the observer in reading off sighted the scale of the hydrometer below the surface of the water, which was done repeatedlv, and the mean of several readings taken, which never differed as much from each other as to amount to a whole unit in the fourth decimal. We were satisfied to measure the temperature of the water but once, that is imme> h '3 Depth. i) S '5 a, m Remarks. a a o CD c3 fcO a 'i a o 02 a Aug. 12 Aug. 13 8i> p. m. 9 10 U a. m. 1 2 3 4 5 6 7 fR 9 10 11 o 32.7 31.5, 31.6 30.7 30.8 30.6 30.6 31.8 36.1 36.5 34.1 37.2 40.6 39.4 38.8 36.6 o 31.2 31. 5 1. 0222 1. 0206 Heavy pack.

As during the period of time over which the above observations extend, the mean temperature of the air was only on two days a few tenths of a degree bslovv the freezing-point, it was warm enough daring the rest of the time to melt portions of the ice siirroandiug ths v»es3el ; and hence we find the specific gravity of the sea to decrease. If we calculate the daily means we obtain the values given in the column of specific gravities, opposite to which the number of observations will be found. Date. Specific gravity. ^ . o w o o Date.

The absolute maximum density of the water of Smith Sound determined in any case was found at noon on August 20, amounting to 1.0288. On examining the observations made during each of the above-named days separately, we per- ceive that the specific gravity of the sea is subject to considerable changes, which become more striking if we consider that, in some instances, the vessel scarcely changed her position during 24 hours. Supposing the sky to be clear, and the temperature of the air to be above the freezing, point, we might reasonably expect that the maximum density of the ice-covered sea would be attained some time after the occurrence of the minimum temperature of the day, and vice versa. A closer EEMAEKS ON CUEEENTS. 13 examinatioa of tbe above observations demonstrates, however, that in some cases the specific gravity was greater in the course of the afternoon than during the night, when the temperature of the air had reached its minimum; for instance, on August 20, when the density gradually increased from midnight till noon. It will be easy to perceive that irregularities of this kind are either due to currents, to the change of the tide, to the influence of the wind, or to a combination of these three causes. We shall demonstrate hereafter that two tidal waves meet near Cape Frazer, one coming from the north and the other from' the south. In the former instance the lighter water from Eobeson Channel and Hall's Basin and in the latter the heavier water from BafQus Bay will flow towards the region in question, where the greater portion of our observations were made, and most likely the irregularities will be partly due to this circumstance. The observations on record that might be used to demonstrate the change of the specific gravity of the sea-water with the depth are but few in number, and are, in consequence of this, of but little value.

We scarcely think the latter to be the case, as great care was always taken in bringing up the water-bottle, the valves of which were in perfect working order all the time. Currents. — If we examine the current-system of Davis Strait and vicinity in its latest repre- sentation on Berghaus' Chart of the World, which embodies an admirable amount of details in the most elegant manner, we perceive the west coast of Greenland to be swept by a warm current. This warm current is represented as part of the Gulf Stream, consisting principally of two branches, the westernmost crossing the parallel of Cape Farewell between longitude 50° and 60° W., while the other sweeps the northwest coast of Iceland, whence it takes a westerly and southerly direction, and passing round Cape Farewell it joins the branch first mentioned. Sweeping the west coast of Greenland, it can be traced to Cape York, whence it sets west toward the entrance of Jones Sound, taking a southerly direction near Coburg Island, and disappearing near Lancaster Sound, from which we notice a cold current to issue, sweeping the shores of Bafiiu Land and Cumberland. In setting south it is joined by another cold current issuing from Hudson Strait, and, desiguated as Labrador Current, continues its way along this coast. In addition to these two main currents, we notice two subordinate cold ones, one running across Davis Strait, near the 70th parallel, while the other, a branch of the East Greenland ice- stream, runs along the southwest coast of Greenland, between the latter and the warm current before mentioned, to about the Arctic Circle, one of its branches joining the Labrador Current near latitude 60°. The materials on which the direction and velocity of these currents are based are derived from different sources, most of which are given in Petermann's elaborate paper on the Gulf Stream,* but evidently some portions were laid down by theory only. It may be advisable, before going any further, to investigate briefly how much reliance can be placed in general in current-observations, made under ordinary circumstances in the arctic seas. * Der Golfstrom uud Standpuniit der therraometrischeu Kenntuias des Nordatlantischeu Oceans und Laudgebietes m Jahre 1870 von A. Potermann. Geograph. Mittheilungen, Vol. XVI, 1870, Heft 6 uud 7. 14 HYDEOGRAPHY. The vessels cruising in these waters are either discovery-ships, whalers, or a few trading-ves- sels of the Danish Commercial Company visiting annually the settlements on West Greenland. With but a few exceptions, the discovery-ships are usually under strict orders to make certain points, and are, in such cases, not allowed to deviate from their course or to stop to make investi- gations ; while the whalers, after they reach the ice, scarcely take any astronomical observa- tions for determining their position, and invariably leave their log-line on the reel until they have again reached lower latitudes. If a discovery-ship is not bound by orders, her commander may then always have a certain aim which he can follow and to which he will make everything else sub- ordinate; and unless this aim be the study of the physics of the sea, we can scarcely expect any accurate observations of this kind. Cases like the latter are of rather rare occurrence, and there are but a few on record, the intention of the commanders of arctic explofing-vessels being in most instances to make such dis- coveries as would most strike the public mind. Unfortunately, however, the public cares very littJe whether a current sets north, south, east, or west, and this is one of the reasons that the number of reliable observations is so small. This small number was only made because nothing else could be done at the time, or because they had to be made, the vessel being beset in the ice, and at its mercy. But even if a vessel starts purposely to make the observations in question, she will, in a great many instances, have to encounter physical obstacles that render the observations less reli- able, and often it will be quite impossible to make any. The direction and velocity of currents are usually obtained by taking the difference between the position of the vessel, as found by dead reckoning, and the position as determined by astro- nomical observation : a less common method is that of making actual expeiiments which require considerable time and care. Owing to unavoidable errors of the dead reckoning, the former mode is far from accurate under ordinary circumstances, and it decreases in value if the vessel has to make her way through" ice, when the log is rendered almost useless, and when she has to change her course so frequently that in some instances it is almost impossible to keep an accurate reck- oning. Those observations obtained when the vessel is beset in the ice and drifting are more valuable ; but it is only under favorable circumstances that they give an accurate idea of the true velocity and direction of the current. If there are bergs scattered through the pack, the direction and velocity of the surface-current, as determined by two astronomical observations, may be consider- ably affected by undercurrents acting on the submerged parts of the icebergs. If there is any wind blowing, it will act on the exposed portion of the berg as on a sail, and thus in many instances solely determine both the rate and direction of the drift. The latter may also be greatly affected by the action of the tide, especially if the vessel is beset in a narrow channel. It is easy to perceive that if we were to examine critically the different observations on record we should have to reject a large number, while others would be of very little value, as in many cases it is quite impossible to determine how much of the drift is due to a permanent surface-cur- rent, how much to the tide, to the wind, or to undercurrents. The value of the few observations made by the expedition, and recorded hereafter, is very small, and we propose to deduce nothing more than general results. We shall first consider the drift of the vessel through Kennedy Channel and Smith Sound, based on the following table compiled from the log by Mr. Bryan : Date. a a ^ o 1-1 "Si WIND. 0'' to & a. m. 6'' a. in. to noou.

As the meteorological observations made during the latter part of August, 1872, are lost, the notes on the winds, contained iu the above table, must necessarily be of a very general nature, so that they will only show whether the wind might have accelerated the drift or not, without furnish, ing the means of determining the approximate rate of acceleration, which iniglit have been deduced with reasonable accuracy if the anemometric observations were on hand. From midnight of August 1-1, when the vessel got beset, till the evening of the 18tli, between latitudes 80° 2' and 79° 41' the mean direction of the drift was almost SW., or more accurately S. 12° W. Between the 14th and 16th it was either calm or light winds were blowing from NE., SW. and from S., most liliely too light to affect the drift, the rate of which during the two days in que^' tion was 5 miles, decreasing to 1 mile during the following 48 hours, and rising to 14.4 between the 17th and 18th. This latter velocity is the greatest on record, and as ^fresh northerly breezes were experienced during the time we may reasonably suppose that they accelerated the rate of the current, the more so as its direction remained the same as during the three preceding days. Most likely this increased velocity is also partly due to the action of the spring-tide, the moon being full at 81' 53".2 on the 18th, and as a rule the set of the flood was experienced to be stronger than that of the ebb, the former being southerly. During the afternoon of the 18th a prime vertical observa- tion was obtained, so that the position of the vessel could be fixed as accurately as the low altitude of the sun permitted. At 6^' p. m. she found herself in latitude 79° 41' N., longitude 70° 19' W., and from this time during the following 48 hours the direction of the drift suddenly changed to about W. 17° N., the velocity decreasing to about 2.3 miles. Between noon of the 20th and noon of the 21st the direction changed again, it being almost due SB., the velocity having increased but slightly, auil all the wind recorded during this time being from the north. Another change of both direction and velocity took place between the 21st and 23d, the former becoming E. 9© S., and the latter having increased from 3 to 6.5 miles, while the resulting direction of the wind during this time was almost at right angles to the set of the current. CUEEBNTS. 17 While up to this time the rate of the current was never less than 1 mile during 2i hours, we see it to decrease to almost one-half of this velocity during the period from August 23 to Septem- ber 6, the wind being very light during the whole time with the exception of two instances when fresh breezes from SW. are recorded. The whole difference of latitude made during this fortnight was only 5 miles, the direction of the set being very variable and apparently quite independent of the wind. This rather remarkable change will most likely find its explanation in the action of the tide. .We shall see hereafter that the tidal wave is propagated from the north to Polaris Bay, while it reaches Yan Reus.selaer Har- bor, which is the northernmost station in Smith Sound where tidal observations have been made, from the opposite direction. It is evident that the two waves must meet somewhere between these two stations ; and until actual observations prove the contrary, we shall look for the line of junction between latitudes 79° 30' and 79° 37', where the drift of the vessel was reduced to a minimum. Between September 6 and 8, the direction of the set was about W. 10° S., the rate increasiug again to 2.5 mile.s and remaining the same until the lith, although the rasultiag direction changed to almost SW., the wind being north during the greater portion of the tims. From the latter day to October 2 the direction was nearer to that of the meridian than iu any of the other instances, the velocity decreasing from 2.5 miles to 1.5, becoming as small as 1 mile between September 21 and October 2. Xhe vessel contiuuing to drift toward the co.ist followeJ its trenl very closely from the 8th till the 13th, the velocity increasing to 8.5 miles, most likely accelerated by the wind, which was from the northeast. The last observation on record is a meridian altitude of the sun, taken on the 12th, and placing the ship in latitude 78° 2S' X., about 6 miles off Gape Ilatherton. " Increasing her distance from the shore, as a glance at t-he map will show, she began to drift to the west side of the channel, taking a somewhat northerly direction, partly caused by a fresh breeze from north- east, which finally changed into a southwest gale. Toward evening she was carried north to the vicinity of Life-boat Cove, at the rate of at least 3 miles an hour ; but most likely this speed was not only due to the influence of the wind, but also, and perhaps priaoipally, to the flood-current, it being the time of spriug-tide. In the sauie latitude, a little to the eastward of our position, Inglefleld experienced a northerly set of 72 miles,* which we do not hesitate to assign to the same cause, as a permanent current o : such a velocity does not exist at this place. In spring, 1873, when traveling from Polaris House to the Eskimo settlement, Sorfalik, where we remained a short time, we paid special attention to the motion of the ice, which, during the time of slack-water, was invariably toward the south. The same direction of the set, only at a greater rate, could be noticed when the tide was ebbing; while, when it rose, the ice drifted in the opposite direction at a speed of about 4 miles an hour. From the preceding observations it becomes evident that the resulting direction of the current i.s southerly, even between Port Foalke and O.iirn Point, wliere Petermann supposed the exist- ence of a branch of the Gulf Stream. That there is no warm current north of Cairn Point may be seen from the observations on the temperature of the sea as measured hourly or at greater intervals, and given at the commencement of this chapter, from which is derived the following table, giving both the mean temperatnre of the sea and that of the air, together with their differences, for the period from August 12 to August 29, when the vessel was between latitudes 81° 5' and 79= 6' i^.: S o -J 1 Date. 1^ D.-2 D* 12 p. ni . . 29.5 8 a. m.. 29.3 11 l>. in.. 29.4 2 p. in . . 29. 2 8 a. m - . 29.0 7 a. m.. 29. 6 p.

But might not a warm cur- rent enter Smith Sound westward of the track of the boats 5 To this question we can positively answer, no, for we fouud the temperature of the sea in no instance above 31°. 6 when crossing from Cape York to the coast of North Devon, during the first part of July. Had there been any traces of a warm current, we should have found them beyond doubt, as we usually took observations every hour, or even as often as every half-hour, when the color of the water showed any changes. According to these observations, the Gulf Stream does not extend north of latitude 75° 5', but how far it reaches cannot yet be stated, as our own meteorological observations bearing upon this' subject are lost, and the material thus far published is scarcely sufficient to settle this question definitely. In McCliiitock's Meteorological Observations t we find the following remark made on the 7th of July, 1857, the Fox being in latitude GOo G' X., longitude 15° 1' W.: "The temperature of the sea-surface vaiicd fjoni 50° to 01° during the day. At noon the following day the position, by observation, was 10' to NE. of the dead reckoning. The yacht, therefore, was probably on the northeru limits of the Gulf Stream." An examination of the same register shows, however, that afterward higher temperatures were noted till the vessel had passed the ]>arallel of Uperni\ik when the water again became colder. Some manuscript observations, kindly furnished by Captain von Otter of the Swedish navy, seem to indicate the same conditions; and until we shall have some more comi)lete data, we shall hold the opinion that the Gulf Stream does not enter Melville Bay. In order to solve the Gnlf-Stream question in a satisfactory manner, the observations on the temperature of the sea ought to be .accompanied by determinations of the specific gravity of the water, because in many instances the high"tempcrature alone isnotsufBcient to jirovethe existence of the Gulf Stream. We have shown that there is no warm current entering Smith Sound, and still we found that on several occasions the teniiierature of the water at Polaris Bay was astonish- ingly high. On the 2d of August, at 3'> p. m., we measured 51o,9 along the shore, a little south of our anchorage and opposite a ravine named the Second Ravine, but at the san.e time the water was almost fresh. * The track may lie fonnd ou the aocoinpauying map, anil the pesitioiis as taken dni-iiig the time are given in the chapter coiitainiiif; the astronomical observations. t Fourth number of Meteorological Pajiers published by authority of the ll;iar(l of Trade, 18ii0. Luidoii : Eyre and Spottiswoode, 18i!ii, p. 4. cueee:nits. 19 We made similar observations along the Greenland coast between Disco Island and Uper- nivik, and in every instance we noticed that these warm spots were almost destitute of animal life, which was abundant where the percentage of salt was normal. It is easy to perceive how and where this high temperature is communicated to the water. The rest of the observations on record that might tend to complete our knowledge of the system of currents do not contain anything new ; they merely help to prove what others prov^ed before, namely, a southerly set in Baffin Bay and Davis Strait. The following table coutains the approximate rate of the current, deduced from the observa- tions taken by Mr. Meyer during the drift of the floe party. As there were but four observations for longitude taken then, we used, in some instances, a graphic process to approximate the velocity more closely. In doing so, we were guided by the general trend of the coast and the prevailing direction of the wind, to which the drift seems to be mostly due : DiUe.

The regular tidal observations made at Polaris Bay, and recorded hereafter, were commenced November 6, 1871, and continued, with the exception of a tew omissions, occasioned by pliysical obstacles beyond our control, until Juue 6, 1872, thus comprising a period of about seven lunations. It was our intention, at tirst, to continue the observations till we left our winter-quarters, but as over half of the ship's crew was absent on a boat journey during Juue and July, and as the ice supporting the tide-gauge began to decay about the middle of Juue, the observations had to be discontinued. The gauge used, and represented in the following diagram, was of the most simple construc- tion, and performed admirably, as au eximination of the record will show. It was mounted over a square hole cut through the ice near the vessel, about a quarter of a mile from sliore, where the tide-wave had free access. It consisted of a pulley and rope supported by a tripod. The rope, to which a wooden scale was fastened, divided into feet and inches, was carried through a block attached to the tripod. One end of the rope was anchored to the i»ottom by three thirty-two pound shot, and a counterpoise was attached to the other end to keep the rope properly stretched. 20 HYDEOGRAPHY. The apparatus was frequently tested by taking series of scale-readings, with corresponding soundings, a number of wliicb may be found in the following table : Soundings, with corresponding gauge readings.

As there was scarcely ever any perceptible swell amid the ice, the scale could be read off to a fraction of an inch. The gauge being too far distant from the observatory to permit of the scientific members of tbe expedition taking the observations without much inconvenience, the readings were taken by two of the seamen, H. Siemens and H. Hobby, who were relieved from the regular duty and devoted themselves with great zeal and, care to their task. The observations were controlled and transcribed by the writer every evening, when the time-piece, made use of in taking the readings, was also compared, and set if found necessary.

DETEI13IINATI0N OP THE HALF- TIDE LEVJ^L. The balf-tide level,* which nudergoes smaller fluctuations than either the menu high-water or mean low-water level, and to which all heights should be referred, was determined by the follow- iug method, iu use at the United States Coast Survey Office : We first tabulated all the heights of the high water and low water in order of their occurrence and placed them iu the third column of the appended table. Then the mean reading of two suc- cessive high waters was placed in the fourth column, opposite the intermediate low water, and the mean reading of two successive low waters was phtced opposite the intermediate high water in the sixth column. The mean between two successive readings in' the fourth and sixth columns, respectively, was then again taken and placed in tiie fifth and the seventh columns, respectively, opposite the intermediate high water or low water. In this manner two mean values were ob- tained on each horizontal line, the mean of which constitute one half-tide level in column eiglit. By this process the diurnal and semi-diurnal inequality are nearly eUminated, and the sectional area of water above the half-tide level at high water will, on the average, corresj)oud to an equal sectional area of water below the half-tide level at low water. An inquiry into the reading of the half-tide level is especially important for the determination of the effect of both wind and atmospheric pressure, and also for the study of the eftect of changes in the moon's and sun's declination, as may be seen iiom some of the following ])aragraphs. Fur- thermore, the zero-point of the scale of the tide-gauge, may undergo changes, in which case the half- tide level readings will furnish a certain test on this point. The table made out in the manner abo\e stated runs as follows: Table sliowing the determination of the half-tide level for the whole nerieu of observations, from Novem- ber, 1871, to June, 187-!. ■:b tc * 'J D;ite.

Both theory and observatiou prove that the atmospheric pressure exercises a considerable effect upon the half tide level of the sea. Supposing that, on a certain day, the atmospheric press- ure be the same at Polaris Bay and at otljer localities, situated a certain distance north and south of this place, and let the pressure increase at Polaris Bay while it remains the same at the other places, it is clear that the water in attempting to reach its equilibrium will flow off in the direction where the pressure is least, thus causing the half-tide level at Polaris Bay to fall. From the complex nature of cases of this kind it will be seen that the solution of such prob. lems is rather difiicult. In accordance with theory, observations made at different locali- ties demonstrate that a rise of the barometer is followed by a fall of the tide-level and vice versa* The results obtained vary, however, very considerably as to the ratio between rise and fall, ratio was found to be for — London, (Sir John Lubbock) 1 • ^ Liverpool, (Sir John Lubbock) . - - 1 : 11 Bristol, (Bunt) 1 : 13.

From the above compilation it would appear that the ratio 1 : 13, which is.nearly the same as that between the specific gravities of sea-water and mercury, is about a normal one. The result of our investigation depends entirely on the record of the barometer-readings as con. tained in the "Table for the reduction of tides, No. 1," to be given hereafter. The half-tide levels as deduced on the preceding pages were also transferred to that table to facilitate the reduction. The barometer-record given there is the mean of two readings: one taken about 1 hour before, the other 1 hour after, the epoch of high water or low water. We proceeded with the investigation as follows : First, we ascertained the mean barometric pressure for the series from all the tabulated readings, by summing up all the columns of barometric readings and finding the mean. The result for each separate month is given in Table A. Table A. Sums and average values of harometer-readi ngs for each month. Month. ■X' ' Number of read- ings.

The nest step was to separate the half tide levels into two groups of values correspond- ing to atmospheric pressures above and below the mean pressure of 29'°.9829. The difference between the mean height and the recorded height of the barometer was set down in another column oppo- site the corresponding half-tide level.* All the columns were finally added up and the means taken.

This makes the ratio between rise of barometer and fall of level 1 : 17. J^ This result is probably affected by incidental irregularities in the variation of the half tide levels and mainly bj^ the wind, which, as is well known, not only affects the barometric column differently as it blows from different quarters, but which, by its mechanical force, also exerts a directly elevatitig or depressiug intlueuce upon the half-tide level. In looking over the half-tide-level readings, there is apparently a. break in the read- ings between November and December, 1871, aud likewise after February, 1872. A careful compari- son of the barometrical record aud that of the wind with the half tide level readings, however, tends to show that this is not actually the case, but that the real cause lies entirely in the change of the non-periodical effects during the different months. To support this view, we give for comparison in Table C the monthly average values of ;half tide levels taken from Table B, and the differences be- tween the average monthly barometric pressure and the mean value 29*^.9829 from Table A. The average declination of the moon for each month is also added, being taken from the tables accom- panying the discussion of the effect of the moon's declination on the variation of the half tide level. In the next column is given the monthly average level reduced to the mean barometric pressure of *In some instances it occurs that only the height of the barometer, or ouly the half-tide level, could be recorded in the '' Table for the reduction of tides, No. 1." In such cases these single values were not taken into account in the separa- tion of values, thereby producing the difl'ereuce in the number of values enumerated in this and in the preceding table. 44 HYDEOGRAPHY. 1^9"'.; I8L".), using the ratio 1:17.4.

The half-tide levels for November and December differ by nearly equal amounts from the mean level of i^^A-i ; we likewise find the barometric elevation of the first month almost exactly equal to the depression in the second month. The mean of the two half-tide levels is 4«.41, differing but 0f*.03 from the average level 4".44. In every instance the half-tide levels corresponding to depressions of the barometric column are above 4f*.44, while those corresponding to elevations of the same are below 4".44. The results are unaffected by change in the moon's declination, as this is nearly the same for each month. The differences iu the last column change sign with the barometer values and apparently indi- cate that a variable ratio is required for each month to reduce them to a minimum. A part of these residuals, however, is traceable to uneliminated portions of the depressing or elevating influence of the wind, which in its average monthly effect seems to have gone hand in hand with the effect of the atmospheric pressure. But there is still another and very important fact not to be over- looked in this connection. While the ratio 1 : 17.4 may represent approximately enough the aver- age atmospheric pressure for the whole period, it does not follow by any means that it is a constant or even a nearly constant value. On the contrary, it is very clear that it must undergo considerable variations under different conditions. For instance, a great change of atmospheric pressure may, perhaps, produce very little or no effect on the half-tide level when the pre.ssure changes equally over a very large area of water at the same time, while the elVect of a smaller change of pressure, when confined to a comparatively small area, may be considerable. From this, it follows that it is not merely the high or low barometer which will cause a depression or elevation of the half-tide level, but that the amount of the effect will depend very largely on the difference of atmospheric pressure at the place of observation and at other localities not far distant. Evidently the con- dition of the ice is another factor affecting the action of the atmospheiic pressure. As we i)resumed the ratio 1 : 17.4 to be affected by the wind, we also investigated the pressure effect solely from the barometer-readings corresponding to the half-tide levels during calms. From 104 readings we find the average half-tide level to be 4Mi(i, corresponding to an average pressure of 3()">.(is(i(i. If we reduce this level to the mean pressure of the scri(\s, 2!l'".(tsi>0, we obtain 4.f'2G + l.f'7 X 0.1037 = 4«.44, which coincides very nearly with the mean half-tide level of the whole series. We then separated the values as we did before into groups of barometer values above and below the mean of 30".0866. The results are given in detail in Table D. TIDAL OBSERVATIONS. 45 Table D.

This ratio may be considered nearly free from the effect of the wind, and as it approximates closely to the results found for a number of other places we consider it to be entitled to some confidence. EFFECT OP THE WIND UPON THE HALF-TIDE LEVEL. The non-periodioal changes in the half-tide level, l)esides being due to a change in the atmos- pheric jiressure, are also greatly affected by the direction and velocity of tlie ]irevailing wind. As the influence exerted liy the wiixd is entirely local, a glance at the chart will tell which winds are likely to raise the water at Polaris Bay and which would produce the contiary effect. It will be seen that the shores of Polaris Bay trend for about 25 nnles in a nearly northerly and southerly direction, curving out sliglitly to the westward about midway and at its northern and southern ends. The bay is thus entirely open to all the sea-winds, and it is but natural to suppose that the latter in sweeping through tl.o straits would drive the water before^ them. The changeable condition of the ice in the straits will, of course, modify the effect of the wind and during those seasons of the year when the ice is more compact the elfect of the wind upon the half-tide level is jirobabiy but very slight. It was our aim to obtain as approximate results as the nature and extent of the data at our disposal would permit. After a preliniiuary in\ cstigation we arrived at the conclusion that it would be ad\i:able to take the elfect of atmospheric pressure into account, as we lound that this effect could not be regarded even as nearly eliminated, when the num- ber of observations was small. The wind-record, as also the atmospheric pressures aud half-tide levels as given in the " Table for the reduction of tides, No. 1," served as the basis for this investigation. TIDAL OBSEEVATIOJfS. 47 The method pursued was as follows : The half-tide levels and atmospheric pressures were classed ioto nine i^rnups, corresponding to calms and to the winds from each of the four cardinal and from fonr intermediate points of the compass. We need scarcely mention that the recorded directions of the wind are the true directions. The velocity of the wind, in mdes per hour, and the number of observations were also set down The values of each group were then added and the mean takeu. The following preliminary table contains the result from each group for each mouth seiuirately. By this separation the dis- tribution of the wind duriug each mouth is made clear at a glance, while at the same time it serves as a means of controlling the correctness of the work, as it enables us to detect easily any serious errors in the sums of half-tide levels or atmospheric pressures.

From tlje preceding table it will be seen that the average balf-tide levels for the different direetidiis of wind have unequal atmospheric pressures, and, therefore, the balf-tide level may, in one case, have too small and in another case too large a value compared with its value for a cer- tain standard pressure. For this standard pressure we adopt the mean value of all the pressures as found in the preceding investigation. This value is 29*°.9829, to which we reduce each average half-tide level by the formerly deduced ratio 1 : IT.Ji. The following table contains the average half-tide level and the barometric elevation above or depression below 29"'.9829 corresponding to it, for calms and for each direction of wind, and also the level reduced as explained above. The approximate average declination of the moon, which also affects the half-tide level, though to a small extent only, is added as a mean of correc- tion if such should be deemed necessary.

As a basis of comparison of the effect of the different winds we use the reduced average half- tide level on the days of calms. By taking the difference between this and each of the other reduced half-tide levels we obtain, at least approximately, the rise or fall of the half-tide level due to the effect of the wind. This effect is recorded in the above table iu the columns headed rise and fall ; the average velocity of the wind corresponding to this effect is given in the last column. The effect may be summed up as follows : Strong north and south winds appear to produce a rise in the half-tide level amounting to between 3'" and 4'". The weight of this result is small and a larger number of observations would probably somewhat change the amount of the effect. The depressing or elevating effect of the wind from the remaining directions is very small in each case, and owing to the comparatively limited number of observations hardly pronounced enough to permit of any definite conclusions being drawn. East winds appear to produce a rise of 0'".9, while west winds seem to have a contrary effect of nearly the same magnitude. For both these winds the average velocity was less than 5 miles per hour. The winds from XE. were the most prevailing, with an average velocity of 17 miles per hour, and apparently depressing the level by 0'°..3, this result possessing the largest weight. The month of Xovember, with only fourteen days of observations, shows comparatively the largest number of NE. winds, with a greater velocity than the average. For this month, as also for March, April, and May, the average velocity is considerably higher than for December, January, and February. This fact, in connection with the variation of the monthly barometric means, would seem to explain, in a large measure, the apparent breaks in the half- tide levels during November, 1871, as also iu March, 1872. To find the effect due to different velocities of the wind, our data are, of course, entirely inadequate ; neither was it possible to ascertain the effect for the different conditions of the ice. TIDAL OBSERVATIONS. 49 EFFECT OP THE MOON'S AND SUN'S DECLINATION ON THE VARIATION OF THE HALF-TIDE LEVEL. Accordiug to theory, the variation in the half-tide level as depeudiug on changes of the moon's and snn's declination can be expressed by the formula — A sin^ '-'m + B sin- (5a where S^ and S^ denote the declinations of the moon and sun respectively. The constants A and B are to be derived from observation, and they are greater near the equator and near the poles than in middle latitudes. Observations made at different places seem to confirm the depend- ence of a rise of the level on an increase of the moon's declination, irrespective of the sign of the latter. The variation in the half-tide level goes through its changes from zero to maximum declination, and the level will reach its lowest and highest values, respectively, at these epochs. Owing to the non-periodical effects on the half-tide level, produced by changes in the atmos- jiheric pressure and by the prevailing winds, which in many cases will exceed in magnitude the variation dependent on the declination itself, an inquiry into this subject with a view to test the correctness of theory, as compared with actual observation, can only give perfectly satisfactory results when the observations extend over a longer period of time than is the case with ours. Another difficultj' attending this investigation is that we have to deal with exceedingly small values ; the range of the variation amounting to a few inches only. Still, we may try to obtain an approximation to the true values, and as far as the result of our investigation is concerned it seems to be quite within the limits of reliability. The method used in this investigation is as follows : The half-tide levels for each day, made out as ex]jlained before, were summed up and the means taken. These mean values are given in the table at the end of this discussi(.)ii, together with the moon's declination for noon of each day, placed opposite the corresponding half-tide level. In some portions of the series an increase or decrease in the levels can be detected by mere inspec- tion of the table ; in other portions the variation is obscured by irregularities, produced by the non- periodical effects. To investigate the accordance of theory with observation, it is necessary to separate the half-tide levels into groups for different values of declination, and to see if the law of the increase or decrease of the resulting means of these groups corresponds to an expression of the form Z + A sin^ «„„ where Z denotes the half-tide level at zero declination, and the second term, A siu^ (Jmi the variation or difference between the levels at declination o„i and zero declination. After trying a separation of the levels into groups for declinations between 0^ and 5^, 5° and 10°, 10° and 15°, &c., we could not obtain a satisfactory result from the means of these groups, the number of values in each group being evidently too small to eliminate the non-periodical effects. To obtain as large a number of values in a group as possible we finally adopted the following- method : By adding all the columns of half-tide levels and dividing the sum by their number we found from 195 values the mean half-tide level L = i^^Aoi) to correspond to S^, = 15° 30'. This value of L appears to be perfectly reliable, and agrees with the mean of the high-water and low-water levels /h.6\) + ^.5j \ _ ^ft^g^ jjg deduced further on in the discussion of the semi-mensnal inequality in height. Next, we separated the levels into groups of values corresponding to declinations below and above the mean o„, = 15^^. 5. The resulting values are — From 90 values L = J:"..jG5, corresponding to S^ = 8° 06'. Fi'om 105 values L = 4".540, corresponding to '5„, = 21° 40'. In order to find the variation and its range we should know the values of the half-tide levels at the moon's zero and maximun declination. We found — From 15 values nearest to zero (5,„, L = 4*.319, corresponding to (?„ = 1° 30'.

We made still another test. Assnming in conformity with the retardation of the tide, as found in tbe di.scussion of the semi-meusual inequality given hereafter, that the greatest effect does not take place at the time of the greatest force, but about 24 hours later, we also investigated the result by taking this retardation of the tide into account, in separat- ing the half-tide levels and using the declination at noon of the preceding day as corresponding to the half tide level on the day in question. The number of groups was the same as before, and In deducing the constants Z and A we used the mean values of all of the five groups. By means of the method previously used we found for the expression of the half-tide level — L = 4".344 -I- 1«.55 sin^ «,„. to render tli(- corrected values more reliable thau tbe v.tI lies given above. In trying to eliminate tbe ettect of attnos- pberic pressure, we gronped tbe barometer-readings in the same manner as tbe corresponding half-tide levels, with tbe intention of reducing the half-tide levels of each group tn a uniform or mean atmospheric pressure. Iq comparing the average atraospbcric pressures corresponding to the five values of (5m, we found the atmospheric pressure to decrease with increasing declination of tbe moon, the range of pressure bi-t\veeii zero and maximum declination amounting to a little o\ er ".1. Cousiilcring the high latitude of Polaris ISay, we have reason to .suppose that this result is merely acci- dental, the more so as tbe eticct of the moon on the atnuispbeiie pressure is scarcely perceptible at Paris, which is about 34- nearer to tbe equator than our arctic station. La Place deduced -j-^ millimeter from a series of observations made at Paris from i.>ctober I, lcl.3, to < letoljer 1, 1--23, but the probable error of this value is almost as great as the value itself {L 5 ^'h Fed. ^' o u " Yi O ' l\(1. re, 1.

The ditfereuees between observed and eomputed values arise partly from the uneertainty of observation, and partly, from uneliminated portions of the I'onperiodieal effects and from the elfect of the sun's declination From all the results obtained we may eonebide with some contidenee tliat the actual range of vari atioii between zero aiul maximum decliuatioii amounts to \eiy little more or less than 3 inches. .Vt the same time the results of this invcstiuation amy serve as a criterion of the value of the observations, which, considering the dillicnlties attending tidal observations in high latitudes, are proved to be very reliable, as will also be seen from the results of our subseiiiieiit discussions. El'FlOCT or' CU VMir',.S l>f TUB SVN'S IIECLIN.VTION ON THE VAKIATION Or' TUB IIALB-TIDB Li;vKa.. .Vs may well be imagined, the elfeet of the sun's declination on the variation of the half tide level is still less than that of the moon, and therefore it is more dillicnlt to deduce, and would rcijuire a series of observations extending over a period of at least twelve nn.inths. For this reason the in\ cstigation'of this effect was omitted. In the expression of the sun's elfect B.siu-'r>s, the constant B is theoretically about ,', A. The range of the variation would therefore amount to 0'''.13 approximately. The process of investigation would be similar to that for determining the moon's cffecU The table used to determine the elfect of the moon's declination is as follows: Tabic for the determination o/' the ctt'eet of changes in the moons declination on the variation of the half-tide level Date Hale.

In reducing the preceding original observations we made use of tlie United States Coast Sur- vey blanks, kindly furnished by the Superintendent of that Office. While the blanks for the sec- ond reduction were used unaltered, we made some changes in the last three columns of Xo. 1. The column headed " Duration of tide" was dropped, and the half-tide levels for low water substi- tuted. The triple column, giving the direction and velocity of the wind, the atmospheric pressure and the temperature, also underwent some changes by leaving out the temperature and sub- stituting the half-tide levels for high water, and instead of giving the state of the weather, as done in the origiual blank, we preferred to use the last column for the moon's parallax and declination. For further explanation we need only state that the time of the moon's meridian passage and of both high and low water is mean time throughout; that the lower transits of the moon are placed betweeu brackets, and that the lunitidal intervals depending upon the lower transits are distin- guished in the same manner.

The preceding "Tables for the reduction of tides, No. 2," contain all the observed lunitidal intervals and heights of high water and low water depending on the preceding upper and lower transits of the moon. The few interpolated values are marked by asterisks. None of the observed values were rejected. To obtain the values for the elucidation of the semimensual or half-mouthly inequality in tinae and height, all the columns in these tables were summed up and their means taken. The mean values for upper and lower transits corresponding to the same or nearly the same hours of transit were again added, separately, for high water and low water, and their average values found. These latter constitute the values of the semi-mensual inequality in time and height. They are given in the following tables for high water and low water separately in the third, sixth, and ninth columns. The means of the twelve values of intervals and heights are the corrected or mean establishments, and the mean heights of high water and low water, respectively.

The inequality or variation of the intervals or heights during the semi-huiation is usually expressed by the differences between the mean establishments or mean heights and the intervals or heights for each hour of the moon's transit. According to the "wave them-y" (Eucyclopiedia IMetropolitana, article "Tides and ^Vaves, '' by G. P>.

This angle a is called the angle of retardation, and from it the age of tlu' tide or the time elapsed between the moon's transit, which originated the tide, and the appearance of the tide itself, becomes known.

Mean low- water springs. . Feet. = 7.24 = 1.84 Hence effect of moon and sun M3 + S3 = 5. 40 Mean high-water neaps = 5. 39 Mean low-water neaps _ = 3. 40 Hence effect of moon minus effect of sun, M3 — S3 — 1. 99 The sum and difference being given we obtain — M3 =5:^+199 =3« 695, and S3 = M2^^1:?i = i« 705 ; Hence the ratio ^^ = }^ = 0.4614. M3 3.695 This ratio is exceptionally large in comparison with the values of ^ deduced for other places: M3 however, it seems to be quite in accordance with the large time values of ^. The ratio deduced from the heights is usually smaller than that deduced from the times, which is also the case with our values, although the difference is not great. For the computation of the inequality in height of high water, S3 was made equal to half the difference between the observed mean high-water springs and high-water neaps, or— S3 = 1:2^=^9 ^0.925. With the ratio above found, we get, then — M3 = ^-^^^ = 2,0047. 0.4614 83^ = 0.8556, M3^ = 4.0192, 83^ + M3' = 4.8748, and 2. 83. M3= 3.7087. TIDAL OBSERVATIONS. 69 The augle of retardation a is determined from the heights by making « equal to that hour angle or value of (m— s)'\ which corresponds to the maximum height ; or, by taking for a that value of ((« — sV' — 6'^ which corresponds to the minimum height. It is best however, to take the mean of the values thus fouud, which in our case is 0'' 50"' = a. Substituting the constants determined above in equation II, we obtain for liigh water — 7i = + %/4.874S + 377087 T^To^'l ({mi'^fi')"-— 0'^ "56"') (A) where h ex^)resses the elevation of tlie pole of the tidal spheroid above a fixed level. In tlie coni])utation of the low-water iue(iaality in height, we take for S^ half the ditference between the mean low-water neaps and iou-water springs, which makes — 8^^ (3.40- 1.8 1)^ ^_-g. consequently, we obtain — . 31,= 0.78 1.6905 0.4614 S;,- = 0.C084, Mo- = 2.7227, S/ + M/ = 3.3331, and 2 S3 . -M3 = 2.5972. The angle of retardation a for low water was deduced in the same way as that for high water, and corresponds to 0"^ 48™ = a. Substituting these values in equation II, we have for the exxiression of the low-water inequality in height — hv=— V 3:3331 + 2.5972 cos 27(Hti' - s>') — 0'^ 48"^) (B) where /; represents the depression of the pole of the inverted tidal spheroid below a fixed level. AVith these two formula?, A and B, we computed the values of /;, and /ii. To obtain the inequality proper, the mean value of /i and/;,, of the two computed series, has to be found and subtracted from each single value of )i and /ij, respectively ; the ditference will be the corresponding inequality. The close agreement between observed and computed values is shown in the table given below, and also in the diagram. The largest difference between the observed and computed high- water and low- water inequality amounts to l"" only. Semi-mcnsual inequaliti/ inlieujlit. FOR HIGH WATER. ar time tran.sit.

AGE OP THE TIDE. The mean retard of the tide as deduced from the time inequalities is a = J (0'^ 53™ + 0'^ 42™.6) _ Qh 47m.8. The age of the tide is found by dividing this quantity a, expressed in minutes of time, by 48.8, (the mean separation in right ascension of the moon from the sun in a solar day.) This 4-7 8 gives for the age of the tide —^=0.9795 days, or 23.5 hours. The mean value of a from the 48.8 height inequalities is a = J (0^^ Se-" + 0^ 48"") = O'' 52 1.065 days, or 25.5 hours therefore the age of the tide is 52 48.8 The mean age therefore is — '- — + ^^-^ — 24.5 hours. 72 HYDROGRAPHY. EFFECT OF CHANGES IN THE MOON'S PARALLAX ON THE SEMI-MENSUAL INEQUALITY IN TIME AND HEIGHT. As the semi-mensual inequality deduced In the preceding discussion is not a constant value, but dependent on the varying declinations of the sun and moon, and on their distances from the earth, a certain correction will be required on that account. It has been fully proved by Mr. AVhewell, in accordance with the theoretical law, that this correction depends on the simple ratio between the moon's parallax and its mean value. In the investigation of this subject it \Yas found by others that the best results are obtained by making use of the parallax corre- sponding to ail ei)Och anterior to the time when the effect lakes i)lace, by the amount of the retard of the tide. We found the mean retard of the tides at Polaris Bay to be about 21 hours. The parallaxes were accordingly taken from the Nautical Almanac for a time earlier by i'4 hours tiian each corresponding high-water or low-water epoch of the series. The luuitidal intervals and heights were then classed for hours of moon's transit between ()'' and 1'', P' and 2'', &c., and the mean parallax for each hour found. The mean parallax for. the series from the values for each houi' is 57'.22 for both high water and low water. In order to obtain as many values as possi- ble in a group we separated the luuitidal intervals and heights for each hour into two groups only, viz, the values corresponding to parallaxes below and those above the mean value for each hour. The resulting means of the separated groups are given for time and height in Table A for high water, and in Table B for low water.

Or, in other words — (a.) For the times : As the parallax increases, the mean establishments decrease for high water on the average by nearly 4 '.6, and for low water by nearly 3'".7, for 1' of parallactic change. (b.) For the helqUn ; As tlie p^irallax iiioreases L', the mean heights of high water increase at the rate of nearly 0".078, while the mean heights of low water decrease at the rate of about O'^'.llS. The angle of retardation a, and, cousequently, the age of the tide, increases with an increase of parallax for times as well as for heights. The periodical effect on the semi-meusual inequality in time and height is exhibited in Tables O and D, which contain the differences or inequalities of each lunitidal interval or height from ite me? n value in the last horizontal lines of the preceding tables. 10 H 74 HYDROGKArHY.

They will differ somewhat from the true ranges on account of incidental irregularities in the numbers of the tables, and when deduced graphically the ranges TIDAL OBSERVATIONS. 75 will probably be more approximate. The ranges appear to be governed by the following general law : ' (a.) For the tunes: As the parallax increases the ranges decrease both for high water and low water. (b.) For the heights : An increase of parallax appears to decrease the range of the high-water inequalities, while for low water the range will increase. The law respecting the ranges, as deduced from the tides at Port Poulke* (latitude 78° 18' ls\, longitude 73° W)., is the same as the above for high- water and low-water times and for high-water heights ; for low-water heights, however, the law is the reverse, although, as stated in the discus- sion, this result is not regarded as fully established. In the following table the periodical effect is also shown in form of a correction to be applied to the semi-mensual inequality in time and height, as deduced approximately from the ratio between the values, when P is below and above the mean parallax 57'. 22. The correction in the column headed " P = 57'.22 " has to be added to the semi-mensual inequality, which is also given in the table. The adjoining columu contains the approximate correction for each minute of parallactic increase or decrease, to be added to the semi-mensual inequality for P = 57'.22, the former with the upper the latter with the lower sign : Correction of the semi-mensual i)iequ(iUty in time and height for the periodical effect of changes in the moon's p<(ralh(.v. a: "a o o Kiu; HIGH water.

Ill From the above table it appears that the corrections for the times are positive or negative, according as the parallax decreases or increases, for all hours of transit, except for that between 5^^ and 6^, where the re\erse is the case. This exception does not appear to be due to in- cidental irregularity iu the numbers, as it is noticeable for both high-water and low-water times for the same hour of transit. The corrections for the high-water heights are positive, and those for low water heights negative, for all hours of transit for increasing, and the reverse for decreasing parallax. * Physical Observations in the Arctic Seas, by I. I. Hayes. Eeduced and discussed by Charles A. Schott. Smith- sonian Contributions to Knowledge, 196. Washington City, Smithsonian Institution, 1807, p. 104. 76 HYDROGRAPHY. The effect of clumges in the sim's parallax on the semi-nieiisual inequality is smaller than that of the moon", and, therefore, it is more difficult to trace. As no reliable results could be obtained from 80 short a series of observations as ours, this subject was not investigated. EFFECT OF CHANGES IN THE MOON'S DECLINATION ON THE SEMI-MENSUAL INEQUALITY IN TIME AND HEIGHT OF HIGH WATER AND OF LOW WATEi;. To obtain perfectly reliable results of the declination effect of the moon, a much loDger series of observations is needed than the one on hand. Our results, therefore, will only be approximate, especially those concerning the periodical effect or variation of the semimensual inequality for different values of declination. The method used in the iuvestigation of this effect is the same as for the jiarallactic effect. We first found the mean declination D for racli hour of transit, and then separated the lunitidal intervals and heights into two groups of values corresponding to D below and D above the mean declination for each hour of transit. The nnnjber of observations was too small to allow us to form more than two groups. The declinations were taken from the Nautical Almanac for a period earlier by 1.'4 hours, or by the amount of the age of the tide, than the corresponding time of high water or low water. No distinction was made in the tabulation between upper and lower transits, nor in regard to the sign of declination. Table A contains the resulting mean values for each hour of transit for the times and heights of high watei'; and Table B for those of low water. For conven- ience' sake, the lunitidal intervals and heights of the semi-mensual inequality are also given.

For the times : WIftn the moon's declination increases the mean intervals decrease for high ■water and for low water. The total decrease between zero and maximum declination is, approxi- mately, from 6 to 7 inches for high water, and 3 to 4 inches for low water. (b.) For the heights : An increase in the moon's declination ap^iears to be followed by a slight decrease in the mean lieiiilit.s of high water, and by an increase of about 5*"^ between zero and maximum declination in the meau heights of low water. (c.) For the angle of retardation or age of the tide ; By a graphical process we find that an increase of declination corresponds to a decrease in the angle of retardation a, for the times as well as for the heights of high water and low water. The decrease is nearly the same for the times of high water and low water, and amounts to about 5 minutes between D = 8° and 15^.5, and to about 4 minutes between D — 15°. 5 and -1°.5. Periodical effect : The periodical effect of changes in the moon's declination is exhibited in Tables C and D for high water and low water separately. The inequalities are the differences between each lunitidal interval and height and its meau value in the last horizontal line of each of the preceding tables. 78 HYDEOGRAPHY.

From the above tables it becomes evident that — (rt.) For the times: An increase of the declination is followed by an increase in the range of high water and of low water ; the increase appearing to be larger for the former than for the latter. {b.) For the heifjhts: An increase of declination increases the range of high water while it decreases the range of low water. By comparing the above ranges with those of the parallactic effect we find* them to follow the contrary law, when both declination and parallax increase or decrease. Before closing this subject we will add the result of a second investigation of the declination effect, intended mainly as a check upon the first. The method we follosved was similar to the one used before, only that we .separated the lunitidal intervals and heights into three groups of values for declinations between 0^ and 12°, 12° and 21°, and 21° and 2.5^. As it would require too much space to print the complete tables, we merely give the condensed result in the following table of the mean intervals, mean heights, and ranges of inequality in time and height, to which we add the values of the first investigation to facilitate comparison.

The inequality ran:;es, which are iu every case the algebraical differences between the largest positive and negative values of each group appear less regular, except the ranges for high-water heights, which are more harmonious. The general law, however, may clearly l-e traced, viz, increasing declinaiion will increase the range of the time and height inequality, except iu the case of low-water beigiits, for which the law is reversed. This irregularity in the ranges is doubtless due to incidental irreg- ularities in the numbers from which the ranges are deduced and which would disajipear if the observations were extended o\er a longer period of time. The periodical effect on high-water and low-water times and heights is given in the tables below in the form of a correction to the Inuitidal intervals and heights of the semi-meusual inequality, so that the reader will find no difficulty iu constructing, from the values derived from the second investigation, tables of the same form as the preceding ones.

For convenience' sake, the semi- mensual inequality is also added. As the periodical effect from so short a series can give but an approximation to the true result, the values for some hours of transit appear to be more or less irregular in the above table. By combining the values of the first and second investigation and taking the means, the resulting values would probably be more approximate. We also investigated the declination effect on the variation in the semi-mensual inequality of the average mean level between high water and low water. While we find that the average mean levels of the different groups increase by a small amount between zero and maximum declination, when D increases, the range of this inequality is a minimum for a mean value of D = 15°. 5 and increases when D is below or above 15o.5. The resulting average mean values of the levels for the different declination values and also the ranges of this inequality are shown in the appended table. For comparison we also add the result of a similar investigation with regard to the paral- lactic effect.

We merely limit ourselves to the statement that the sun's effect is much smaller than that of the moon, the correction amounting to from .V to a of that of a correspoiullug value of the moon's declination. DIUENAE INEQIJAEITY, The diurnal inequality in height and time is the difference in height and in the lunitidal inter- val between the morning and afternoon tides, respectively. This difference or irregularity being caused by the interference of two independeut waves called, on account of their periods of oscil- lation, the semi-diurnal and diurnal wa\'es, has been found to depend closely on the varying declina- tions of the moon and sun. This inequality goes through its changes in a semi-lunatiou, reaching its maximum at the epochs of the moon's greatest north or south declination and vanishing when her declination is zero. Practically, however, the epochs of maximum and minimum inequality do not, in most cases, coincide with the epochs of the moon's highest or zero declination, but are usually retarded. Diurnal Inequality in HeigM.— The diurnal inequality in height was made out by a graphical process in the following manner : First, the observed epochs and heights of high water and of low water were laid down as absciss* and ordinates on a sj^stem of lines drawn for this purpose on Plates I and II. To obtain the high water inequality the high waters next following the moon's upper transit and those next following the lower transits were connected by separate auxiliary lines. The vertical distances between these auxiliary lines were then plotted on a straight axis as abscissae on Plates III and IV, and their extremities connected by curves. The ordinates of these curves represent the values of the diurnal inequality in height of high water. To obtain the diurnal inequality in height of low water the same process was applied to the low waters. On Plates III and IV the low-water height inequality is shown below the high-water height inequality of each month. The vertical distances belonging to the high waters and low waters next following the moon's upper transit are counected by full lines, those belonging to the lower transit by broken ones. It must be remembered that in north latitudes the south transit of the moon is the upper, the north transit the lower one. The phases of the moon and the epochs of the moon's zero and maximum declination are also indicated on the plates. The diurnal inequality in height appears to be governed by the following rule : For north declination that high water or low water which follows the moon's upper transit, on the average after an interval of 12^- hours for the former and of ISJ, hours for the latter, will be the higher one of the two high waters or the two low waters of that day ; while if the moon's dec- lination be south it will be the lower one. This rule requires a certain correction, to be given here- after, as the epochs of the moon's zero declination and of the disappearance of the diurnal inequal- ity do not coincide. The same rule was found for the Port Fouike tides, but pro])erly for the high waters only, the diurnal inequality in height of low water presenting the anomaly of disappearing at about the time when the diurnal inequality in height of high water reaches its maximum value. We further find that a high low water is as a rule followed by a low high water,* with exceptions, however, at about the time of the moon's crossing the equator. For the coasts of Europe this rule is different, a high low water being usually followed also by a high high water. The diurnal inequality in the heights is very small, being less than half of that for Port Fouike and Van Rensselaer Harbor, which are the two next stations south of Polaris Bay where tides have been recorded. The inequality curves of our series are irregularly shaped lines, intersecting the axis near the epochs of the moon's zero declination. In conformity with the rule given above, the curves depending on upper transits fall above the axis, or their ordinates are positive, when the moon 's declination is north ; and they fall below the axis, or are negative, when it is south. The difference 'According to Koldewey the tides of Sabine Island show the same peculiarity. Compare "Die zweite dentsclie Nordpolarfahrt," vol. II, p. 662. 11 H 82 nYDEOGEAPHY. between the avenme rauge of the high-water aud low-water inequality is very small, the mean uiaxinuim range anionnting, by measurement of the eurves. for both high and low water to about 1 foot. This small range appears to be quite in conformity with the tidal theories, according to which the iuequality is small in high latitudes. The interval between the epochs of the moon's zero declinations and the epochs of disappearance of the diurnal inequality in height is exhibited iu the following table : Ti(hlc slioiri)ig the epochs iclien the diurnal inequality in height reinishes, and also the intervals between these ejjoelis and those cf the moon's :eri> deelination.

The low-water inequality presents the anomaly that the intervals are confined to about two days before aud two days after the epochs of tlie moon's zero declination. Thus for high water the min- imum inequality happens on the average!.'. 9 daysa/Ter and for low water 17 hours before the epoch of minimum force.* ^Ve are not aware of similar results for other places, but we believe that at Kur- rachee, India, from three years of observation the maximum of the diurnal tide has been found to take place before the maximum of the force. According to Sir J. Lubbock, the lunar component of the diurnal inequality can be expressed by the formula, o^ = sin 2 S^, where S^ denotes the declination of the moon and a constant to be determined from observation. In our case the small range and the complex form of the inequality curve make its mathematical representation from so short a series unreliable, ami therefore of little value. The average form of the diurnal inequality curve, freed more or less from all incidental irregularities, is probably nearly enough expressed by the formula — ()], = 14.."> sin 2 ^m for high water, and ,\ = 13.05 sin 2 S^ for low water. Diiu"nal Inequality in Time. — The diurnal iuequality in time has been made out on Plates Y aud YI in a manner similar to that for the height inequaMty. The lunitidal intervals were laid down " For Van Rensselaer Harbor the diurnal inequality in height of high water disappears on the average 1.6 days and for Fort Foulke 1.9 days after the epoch of the moon's zero deelination. For the latter place the apparent retard of the diurr.al inequality in height of low water is on the average 9.8 days, this long retardation being explained as the eft'eet of interference of the diurnal with the semi-diurnal wave, but we do not believe that such an exphanation could apply to our case. If we were to deduce the intervals given in the above table that now h.ive a negative sign, throughout, from the preceding epoch of the moon's zero declination, we shoirld obtain a retardation extending not only over the whole period of a semi-lunation, but it would, in one instance, be at least two days longer. This explanation might be plausible if the tides observed at Polaris Bay were produced by the same wave as those at Van Keusselaer Harbor aud at Port Fonlke; but a comparison of the cotidal hours of the three places conclusively shows that the two tidal waves are propagated from entirely different directions.

The epoelis of disa[>i)earanee of liie inequality are very variable, and appear for higli water to be eontined to between 3.3 days after and 1.1 days before the moon's zero deelinatiou, representing in this respeet the same anouudy as the height iueqaality of low water. The average aeeeleration of the epoeh of disappearanee amounts for the high-water inequality to about l.D days. The low-water inequality epoeh varies fiom 1. 1 days after to 1.-3 days before the moon's zero deeliuatiou. The average retard is 2.1 da\s. whieh is nearly the same as for the height inequality of high water. The average maximum ranges of this inequality are very nearly alike for high water and low water, being about 1^ 13'" for the former aud P ;•" for the latter. SETAKATIOX dF THI-: KKsfLaWNT TIDK AY AVE INTO ITS COMrOXEXT PAlM's. The eomponud tidal wave, as is well known, consists of a eombiuation of the semi-diurnal and diurnal waves, The former has. on an average, half a lunar day for its period from low water to low water, while the latter, whieh depends for its height ehietly ou the deeliuatiou of the moon, goes through its changes from low water to low water in about a solar day, and produces the diur- nal inequality iu the heights and times of the tides. In order to study these two waves, the resnltaut tidal wave, as observed, has to be separated into its two eomponent waves, whieh may either be tlone ana1> tieally or by means of the graphic proeess devised by L. F. Pourtalcs. As the former treatment involves too mueh labor, we made use of the latter. The result derived iu this manner is given ou Plate IX. where the series from January 1 to January S. aud from May '2'2 to June ti, l^JTi', are represented. We [inr[iosely chose these series because they are the most accurate aud complete ones, consisting mostly of half-hourly obscrsa- tions or of readings takeu at intervals of 10 minutes near the turn of the tide. The observed or resultant wave is indicated by a broken aud dotted line, and the semi-diurnal and diurnal waves by full lines, the latter being shown below the two former. It appears as a very low wave of ineg- ular shape, with a maximum rauge of about 13 inches, which is considerably less than the range of the diurnal wave observed either at Port Foulke or at N'au liensselaer Harbor. The relation betweeu the declination of the moou and the diurnal wave is shown clearly in the series from ]May '2'2 to June 0, the sjiriug and neap tides heing marked by a slight ditiereuce in heiuht. The irregu- larity of the diurnal wave and its small range render a detailed iuvestiuation of its lorm very difti- cult, aud, as the scries of obsei\'ations is slunt. the result would be perfectly unreliable. For this reason we limited ourselves merely to the in^ estig ition of the form of the resultant spring and neap tide waves. INVESTIGATION OF TllK FOKil OF THE TIDE AVAA K>. The tide wave being the result of the action of periodic forces, its form, aside from non-peri- odical disturbances, ought to correspond very closely to the laws governing the action of such forces. Iu the followiug we give the results of ouriuvestigation of the form of the two most prominent waves iu each seiui-lunation, namely, of the spring and neap tide waves: The spring aud neap tides, that is. the hourly observed heights of the tide occurring about one day after new and full moou, aud the heights of those occurring about one day after the first and last quarter of the moon, as also those of' the tide preceding and followiug each spring and neap tide, were extracted from the whole series. These tides were next clas^ed for springs and neaps separately into groups corresiHnidiug to tides of equal i^eriods of time from low water to low water, A tide having its low water, for instance, at 7'' 30'" a. m. aud the succeeding low water at 7'' p. m., its period would be classed as i^ aud 11'' ; a tide having its low water at V>" a. m. and the next low water at o^ 30'" p. m,, its period was set dowu as ll'^ aud P'; a tide having its low water 84 HYDROGRAPHY. at r> 15'" p. 111. and tlic following low water at 1" 45'" a. m., its period wa.s couutcd f and IL"' and i^, &c. The lioml.v lieigbts ot eacli group, as also tlio.se for the fractional hours at the beginning and end of eaeli period, were then added up and their mean values found. The mean values of each group were then thrown iuto curves, the heights being laid down as ordiiiates and the correspond- ing times as abscissie. The period from low water to low water in each curve was then divided into IL' equal parts and the height corresponding to each was carefully measured off with the scale used in the construction of the curves.* The 13 equidistant ordinates from each curve were then set down in 13 columns, and each column added up and its mean value taken. For the mean ordinates of the siiring-tide wave from 41' observed tides we obtained the following values: IMX;, li'vSl, 3".L'7, 4".51), .-y.97, C".91, 7".32, C".95, oM)7,'4^55, 3\27, 2".32, 2".02; and for the neap tide wave froai 30 observed tides : ;;".23, ;;".4(), 3".81, ¥'.36, 4".".»0, 5^29, 5'U2, 5^31, 4'-'.89, 4f'.34, 3".82, 3".49, 3".30. Apul.ving to these values Bessel's well-known function of the action of periodic forces, the siiriiig-tide wave will be found closely represented by the expression — h = (2".(l'.» + lf>.93) + 2".0(!4 siu (0 + 270'3 02') + 0".035 sin {2 O + 85° 16') and the iiea[) tide wave by — /( = (1M3 + 3" .23) 4- 1".0.j8 sin (d -f 209;' .".O') -f O'^'.OIS sin (2 + 144° 47'.) For these e(]uatious the period from low water to low water is conceived to correspond to 360° of phase; for 12 equidistant observations of heights between the two low waters the angle increases therefore successively fiom 0° to 30°, 60° ... . 300°, 330°, 300°. As the difference of level between the two low waters is less than 1"' in each of the two waves, the constants in the above equations were comjiuted directly from the numbers representing the mean ordinates of the waves, after subtracting from each ordinate 1".93 and .")''.23, respectively. For the computation of the ordinates these values have again to be added, and appear, therefore, in the first term of each equation. For Van Rensselear Harbor the corresponding expressions for the form of these two waves are for the spring-tide wave — ■ h = ,5".83 + rj".58 siu {0 + 278°) + 0".20 sin (2 d + 281°) and for the neap-tide wave — /(. = 2".42 + 2".25 sin (0 + 269°) + 0".09 sin (2 + 290°.) For the form of the diurnal and seini-diurnal waves observed at Port Foulke the following expressions were found : for the diurnal wave — /( = 1".50 -I- 1".56 sin {0 + 270°) + 0^08 siu (2 ^ -f 135°) and for the semi diurnal wave — /( = 3".7.5 + 3". 79 sin [d + 275°) + 0'''.21 siu (2 ^ -|- 194o.) The agreement between the observed values and those computed by means of our formula is shown in the table given hereafter and also in the annexed diagram.

It appears tbat the two slopes iu each wave are very nearly syiumetrica], which is quite io accordauce with the durations of the rise and fall of the tide, as these differ very little, the rise occupying but C minutes longer than the fall. PROGRESS OP THE TIDAL AVAYE. Having diseussed thus far the tides of Polaris Bay, it only remains to iuvesti.gate from which direction the tidal wave is propagated to the locality in tiaestion ; whether it is the Atlantic wave entering Davis Strait or a wave traveling along the east and north coasts of Greenland; whether it originates in the Polar Sea, or whether it comes from the Pacific Ocean through Bering Strait. Evidently, the wave reaching Polaris Bay cannot be propagated through Davis Strait, as an examination of the following table will readily show : the different localities given there being all situated on the west coast of Greenland, and arranged according to increasing latitude.

As he cotidal hour of Polaris Bay, situated ISO nautical miles north of Van Eensselaer Harbor, is 8 minutes earlier than that of the more southern station, it is easy to perceive that the two localities must necessarilv be under the influence of different waves. 86 HYDKOGEAPHY. IJiiriug our stay iu Greenlaud we were led to the belief that the tidal wave- reachiug Tolari.s Bay was coming from the Pacific Oceau through Bering Strait; but when, after our return, we could compare the literature ou this subject we soon found this to be an erroneous conclusion. In order to show that the wave in question cannot be a derivative of the Bering Strait tide, it will be sufBcieut to state that the latter is a simple lunar semi-diurnal tide- As uj) to this time we do not know positively whether there is an extensive body of water around the pole, where a tidal wave might originate, we may be allowed to conclude that the wave reaching Polaris Bay is an Atlantic wave, progressing along the eastern and northern coasts of Greenland. In support of this view we give the following table, containing the result of the tidal observations made in Kast Greenland duriug the second German expedition under Captain Kol- dewey. Locality.

A comparison of this representation with others of earlier date, where no use had been made of the Greenland observations, will show that we had to modify the course of our lines considerably in order to satisfy the different observations. The lines north of latitude 81° are purely hypothetical and were merely put in to show the probable correctness of our view that the Polaris Bay wave rounds Greenland before it reaches this place. The heavy line running across Smith Sound represents the approximate place of junction of the two Atlantic waves, and we suppose that the one entering through Davis Strait does not affect that portion of the Sound which is shaded by vertical lines on our map.

It A RECORD AND DISCUSSION OF TEMPERATURES AT POLARIS RAY. Although we entered our winter-quarters during the latter part of Sei)teniher, 1871, we were unable to begin the regular hourly LDeteorological observations before November 6th, because no hands could be spared to finish the observatory, which had been set n[) on shore a few days after we had anchored at Polaris Bay. DESCRIPTION OF STATION AND OBSERVATORY. The observatory was a small building, situated in latitude 81° 36'. 4 north, longitude 62^ 15' west of Gri enwich, and adjusted in the meridian as nearly as could be done. It was placed .'U feet above the mean sea-level on a nearly level plateau, consisting of a grey, slaty, Silurian limestone, entirely covered with drift of the same material and of primitive rock. This plateau, deeply intersected by ravines, stretches from north to south. Its length is about 10 miles, its average breadth about 4, as a glance at the map will show. Toward the north it is bounded by mountains varying in alti- tude from 900 to 1,200 feet, which gradually slope to the eastward into a chain of hills not over 400 feet high. The mountains bordering its southern limit rise to an altitude of a little over 2,000 feet. The observatory, a plan of which is given on Plate I of this chapter, was made at tlie New York navy-yard a short time previous to the sailing of the expedition. It was built of half-inch pine plank, and could be taken down and put together in a very short time. Its length was 10 feet, its width 8 feet, and its greatest height 8.5 feet. The roof had a slope of about 33 degrees, and was provided with four shutters, two on each side. The door was about 4.8 feet high. Origi- nally the little building had no window, as the latter was not deemed necessary on account of the absence of the sun during the winter. Early in spring a square hole of about 1 foot by 1^ was cut through the roof and covered with a pane of glass. As soon as there was sufficient snow the whole building was banked in with a wall about 3 feet in thickness, as represented on the ground-plan (Plate II). For further protection against wind and low temperatures, a tunnel of snow-blocks was built leading to the door, and at the same time to the two magnetic huts containing the declino- meter and dip circle (see Plate II). In order to afford sufficient jnotection to the thermometers without depriving them of the free circulation of air, they were put up in a louver- boarded box, 6 feet high, 3 feet wide, and 1.8 feet deep. This box was fastened to the eastern wall of the observatory by means of strong iron brack- ets, leaving a space of a little more than 2 feet between it and the wall (Plate II). In anticipation of heavy snow-drifts, usually interfering with accurate observations, the thermometers were sus- 4 TBMPBRATUEB OF THE AIR pended on a oatro revolving round a perpendicular axis lastcned in tlie vvnUn- of tlio box, as shown in the accompanying sketch. The bulbs of the instruments, suspended iS, feet above the ground, were all on the same level. IXHTiajiMENTS. The expedition was supplied with the following instruments, all graduated according to Fahrenheit's scale, viz: 10 spiritthermonieters (standard), by L. Casella, London. 10 mercurial thermometers (standard), by L.

COMPARISONS OF THERMOMETERS AT THE TEMPERATURE OF MELTING ICE. As the comparisons taken at Polaris Lay were lost during th(^ wreelc, we give anothei' set of readings taken at Polaris House, October .il, 1.S7-!. The instruments were susitended over a bucket filled with lumps of melting ice, in which the bulbs of the thermometers were immersed. The readings were taken at the intervals specified in the first column, headed "Time". AT POLARIS BAY. Time, Oct. 31, 1872.

Altlioiigh tlie psychrotnetric ohseivatioiis were taken hourly, we still eonsidered it better not to make use of the readiuss of the dry bulb U> obtain the temperature of tlie air, as the indica- tions of this instrument are always more or less influenced I)y the evaimration taking place at the surface of the wet-bulb thermometer. Therefore a mercurial standard, (by Green,) which had been carefully coaipared by Mr. Meyer with the naval standard at Washington, was read for this pur- pose. Its correction was found by him to be —0°A. This instrument was an excellent .me, but unfortunately was broken .luiing the disaster in October, 1S7L'. All the observations of tempera- ture at Polaris House were taken with one of Oasella's standards, the corrections of which had been determined at Polaris Bay, and we're afterwards found in one of the meteorological note books.

In order to get a complete year, we made use of some hourly observations, comprising the period from August 12 to August 31, 1872, which, however, were not taken at Polaris Bay, but while the vessel was beset in Smith's Sound. From September 1 to November 6, 1871, we have only three observations a day, extracted partly from the log-book, partly from some blanks (Form 4), as issued by the United States Army Signal- Service (division of telegrams and reports for the benetit of commerce). These blank^s, which had been filled by Mr. Meyer, were found on board the ship after the separation from the ice-party had taken place. The observations were taken 30 minntes later than their recorded time. The minutes have been omitted in the record given hereafter, in order to avoid unnecessary figures. Up to JSTovember 6, 1871, all the observations were taken by Mr. Meyer and the writer, re- lieving each other in eight-hour watches. From this date to January 18, 1872, Mr. Meyer observed sixteen hours and the writer but eight. After the 18th of January, Joseph Mauch, an intelligent seaman, who had been well trained in taking observations, began to stand an eight-hour watch, so that the twenty-four hours were equally divided between Messrs. Meyer, Mauch, and the writer, 8 TEMPERATURE OF THE AIR During tlie time of the boat-journey north, when Mr. Meyer and the writer were absent from the shii), the observations were taken by Messrs. Bryan and Mauch. During the seven months spent at Polaris House, Mr. Bryan observed eight hours a day and the writer sixteen. From November 1st to November 16th Mr. Bryan's place was sui)plied by Mr. Mauch, and during the s[)ring, when the writer was absent on several occasions, Noah Hayes as- sisted most materially in taking the observations. All the general remarks made in reference to the record of temperature apply equally well to the rest of the meteorological observations, unless stated otherwise. The sun disappeared October 17, 1871, and reappeared February 28, 1872, although the faint twilight-arch, the altitude of which was 3° 16' on December 6th at noon, was visible during the whole period of darkness.

ANNUAL FLUCTUATION OF TEMPERATURE AT POLARIS BAY. In order to discuss the preceding observations analytically, botli the daily and monthlj' means are required. As has been mentioned before, there are only eight-bourlj' observations on record for the months of September and October ; but three daily observations, if separated by proper intervals of time, will give the mean temperature of the day, provided the respective weights of the observations under consideration can be estimated. The latter can be done, a.s we know the law of the daily fluctuation of temperature at quite a number of stations situated in the arctic regions. Denoting the three observations under consideration in their succession by fi, /j, and fg; denot- ing further three other observations, taken during the same month, day, and hours, but at another station, by rj, tj, and rj, and the mean temperature of the day at the second station by p. ; if Wj, W2, W3 are the weights of the observations at the first station, we may say with some reliability that— 111 ■IC\ : M'2 : ?r3= : : (/^-Ti) {p-^%) {p--T:-i) Having thus obtained the weights of three observations at the first station, the mean can be calculated according to the well-known formula — M'l + -"^2 + W3 By this somewhat laborious, but otherwise simple method, the daily means have been com- puted, from which subsequently the monthly and annual means have been derived. The period under consideration comprises one year of 366 days, which was divided into twelve equal parts of 30.5 days each, and the means of these equi-intervals were formed in order to use them as monthly means in Bessel's circular functions. The following table will show how little they vary from the means of the actual months : AT POLAEIS BAY. 21 Comparison of the means of the actual months and the eqid-intervals. Months.

Stopping with our approximation at — <^ = +0.00025 d X which corresponds to ,«=215o 4', we obtain the maximum of— +390.5 on July 21st. The lowest temperature occurred in the middle of February, though there was another mini- mum of— —240.7 on February 3d. By inserting T=+4.196 in the analytical expression for the annual fluctuation, the roots of the equation will give the phases, when the mean annual temperature occurs. These roots were found by approximation,'and we see the mean temperatures to occur on — May 1st and October 8th. The following diagram exhibits the annual fluctuation of temperature at Polaris Bay : g SB The strong curve represents the computed values, the other one the temperatures actually observed. It will be seen that the greatest dift'erence between the computed and observed values occurs in August, namely, — lo.72. Then follow September with a difl'erence of +I0.68, June with + 10.38, December with — lo.27, February with +10.23, and March with — lo.02. None of the other differences exceed one degree. In the present case the greatest difference occurred in summer, while at the other neighboring stations it was found during winter or spring, when sudden changes AT POLARIS BAY. 23 of temperature are more frequent. Au examiuation of the hourly observations shows that during November the temperature rose, sometimes within one or two days, from —25° to +5°. The same was found during the two following months, and especially in February, when changes of 40°, and even more, were not at all uncommon. The following table gives the observed annual fluctuation of the atmospheric temperature for different stations in the arctic regions, four of which are situated on the northwest coast of Green- land, one in the Parry Archipelago, and another in East Greenland: Periods.

It will be seen that every month at Polaris Bay was warmer than at Rensselaer Harbor, the greatest diiference between the two localities being exhibited in December, during which month the mean temperature was 15o.l3 higher at Polaris Bay. The next greatest difference of 13o.30 occurs in November; then follows IMarch with llo.iL If we except September, which, accord- ing to the observations at our first winter-quarters, was Qo.SO warmer there than at Rensselaer Harbor, none of the other differences exceed 6o.5. The greatest difference between the mean temperatures of the two localities occurs in autumn and winter, the temperature at Polaris Bay be- ing 80.43 above that at Rensselaer Harbor in the former season and 80.I6 in the latter. The differ, ences between the temperature at the two stations in spring and summer was 50.8I and 3o.93, re- spectively; and the mean annual temperature is 6o.59 higher at Polaris Bay than at Rensselaer Harbor. Our observations taken at Polaris House, which are given in detail hereafter, are of special interest (although they do not extend over a whole year), as this station is situated be- tween Port Foulke and Rensselaer Harbor. The mean temperature of January was found lower- at our second winter-quarters than that of the same month at the two stations last mentioned, although it was by 50.6 higher than during the corresponding month at Port Kennedy. Both Feb- ruary and March were colder than at Port Foulke, but warmer than at Rensselaer Harbor, while the mean temperature of April was higher than that of the two other localities, which was due, most likely, to a body of open water to the south and west of the station under consideration. May again was warmer than at Rensselaer Harbor and colder than at Port Foulke. The same was the case in November and December; and a comparison of spring and winter demonstrates the same fact again. Consequently, there is a decided decrease of temperature with increasing lati- tude between Port Foulke and Polaris House aud between the latter station and Rensselaer 24 TEMPERATURE OP THE AIR Harbor. An examination of the mean temperatures of the station last mentioned and of those of Polaris Bay demonstrates the contrary, viz, an increase as shown in the following table, giving the increase of the mean temperature for 1° of latitude between latitudes 78o.6 and 8I0.6 north.

North Star, at Wolstenholm Sound in 1849 and 1850, in calculating the decrease of the temperature with the increasing latitude, we get the following table, Port Foulke being used as the northern station : Change of mean temperature for one degree of latitude between latitudes 76o.5 and 18°.3 K January February March April 0.5 +.\0 2.7 4.0 May June . 1.1 3.2 0.0 +1.3 September October November December 2.5 2.11 +11.9 + 8.0 Sorinff . 2.6 0.6 +2.4 +4.2 Summer Autumn July August Year = = + 0°. 85. AT POLARIS BAT. 25 There is a decided decrease manifested except in February, August, November, and Decem- ber, and accordingly in autumn and winter the temperature at Port Foulke is found to be the highest. The same takes place in regard to the annual temperature, which is by Qo.SS higher at the latter station. An examination of Hayes's narrative shows that there was considerable open water near his winter-quarters during November, December, and even during February, which circumstance will readily explain the higher mean temperatures during these months. The mean temperature of August at Port Foulke is not strictly comparable with that of Wolstenholm Sound, as it had to be interpolated, although we doubt that the difference between the value actually observed and the one in question would exceed lo.3. The observations taken at Cpernivik, combined with those of Wolstenholm Sound, give the fol- lowing result: Change of mean temperature for one degree of latitude between latitudes 72°. 8 and 76°. 5 If.

It will be seen that there is a slight increase of temperature in May, June, and July, all the other months being colder at Wolstenholm Sound. By omitting the station last mentioned and calculating the decrease between Upernivik and Port Foulke the result turns out more favorably as may be seen from the following table, in which there is but one slight irregularity in July, this month being by 0o.3 warmer at the northern station: Decrease of mean temperature for one degree of latitude between latitudes 72o.8 and 78o.3 N.

From the above tables it appears that there is a decided decrease of temperature with increas- ing latitude, between latitudes 72o.8 aud 78°. 6, from whence to latitude Slo.G the contrary takes place; consequently, we might say that the climate of West Greenland is of an insular character on the southern'part of the coast, assuming a continental character near and in Smith Sound, and growing milder again in the latitude of Polaris Bay. The difference in temperature between the extreme seasons, viz., summer and winter, increases from latitude 60° to latitude 78°. 6, from whence to latitude 81o.4 it decreases again, as exhibited in the following table. Beyond doubt the difference of Wolstenholm Sound is anomalous, resulting from local influences: Stations.

At first sight it seems to be rather strange to find the mean temperatures of stations situated under the same parallel, on the eastern and western coasts of Greenland, almost equal, as the former is under the influence of a cold marine current, so much loaded with heavy drift and pack ice that it is always more or less difiBcult to reach this coast, while the other, to a certain latitude and at certain seasons, is washed by a warm current. Under such circumstances we might reasonably expect the temperature to be higher at a station situated at the western than that of another one situated at the eastern coast under the same latitude ; but this, however, is not the case. Our present knowledge of the interior of Green- land, between the latitudes mentioned above, shows that the so-called inland ice stretches nearer to the -west coast than to the one opposite. Therefore, it is easy to perceive that during the warm season the vicinity of the inland ice compensates for the action of the warm current along the western coast, while the more rocky surface of Eastern Greenland, heated by insolation, modifies that of the ice-stream. Consequently, the isothermal lines cannot run parallel with the parallels of latitude, but will represent curves, the convexity of which is turned toward the north. Most likely the apex of these curves between latitudes 69° and 74° north will be situated between longitudes 30° and 40° west, while farther south it will attain a greater west longitude. DIURNAL FLUCTUATION OF THE TEMPERATURE AT POLARIS BAY. The following table, exhibiting the mean maximum and minimum temperatures of each month, with their range and the time of their respective occurrence, is derived directly from Table II, given after the hourly record : Daily extremes, range, and hours of maxima and minima for each month of the year.

AT P0LAEI8 BAr. 27 It will be seen that the hour of occurrence of the minimum in October is omitted in the pre- ceding table, being due to the circumstance that it is not well established, because the observations for this month are incomplete. The following diagram exhibits the annual march of the diurnal amplitude for each month: It appears from the above that the maximum value of the daily range is reached in April, amounting to 7o.94. An examination of the amount of cloudiness shows this month to be the clearest one on record, the percentage of perfectly clear hours being 20.3. Consequently, terrestrial radiation takes place more freely, and as the sun is not yet circumpolar during the earlier part of this month, changes of temperature are more frequent; besides, the temperature of the dew-point is nearly 8° below that of the air. From April the daily range decreases till July, when it begins to rise again, reaching a second maximum in August; the minimum occurring in October. Another small rise takes place from this month till January. We tried to obtain the dependency of the daily range upon the hygrometrical conditions of the atmosphere, but did not get any satisfactory result. The following table gives the daily range of temperature for six stations in the arctic regions. The maxima are denoted by asterisks while the minima are placed between brackets: Months. Polaris Bay.

At Sabine Island the maximum is greater than at any of the other localities. The minimum of Polaris Bay occurs in October; that of Rensselaer Harbor a month later. Both at Port Foulke and Port Kennedy the range is smallest in December, wliile at Sabine Island the minimum occurs in January. The daily range never disappears entirely in any of the above-named stations, although in winter, when the sun is below the horizon, the thermal wave becomes very insignificant. During this time we might reasonably expect a decrease of the minimum witli increasing latitude, but this does not seem actually to be the case, at least if we judge, from the observations above given, which, however, do not extend over a period long enough to admit of deducing a general law. The analytical discussion of the diurnal fluctuation of the temperature at Polaris Bay is based on the table headed "Daily Means," given after the record of the hourly observations. The annual means of every hour of the day were taken and used as phases of the daily period. The elements of the analytical expression were found as follows: n «n 6„ Bn C„ 1 2 3 4 —0. 89338 —0. 00183 +0. 03907 —0. 0625 —0. 22293 -0. 10781 +0. 007875 —0. 049073 0. 92078 0. 1078 0. 03986 0. 07946 ' n 255 59 30 180 5.S 24 78 3(; 14 231 51 37 Consequently, our analytical expression becomes — T=4,196+0.92078 sin {x+255o 59' 30")+0.1078 sin (2ir+180o 58' 24") +0.03986 sin (3 ^^+78° 36' 14") + 0.07946 sin (4 ir+231o 51' 37") The period being referred to noon or midnight at its beginning, the angle x increasing at the rate of 15° per hour.

We shall see hereafter that this anomaly is produced by the somewhat abnormal march of the temperature during June and July, the maximum tempera- ture of the day being reached as early as IP a. m. in both of these months. In general, the com- puted values agree very well with those observed, the greatest difference between the two not exceeding 0°.19. At Van Eensselaer Harbor the maximum occurs at 2'^ p. m. and the minimum at l*" a. m. At Port Foulke the hours are 2^^ 30" p. m- and 2'' SO-" a. m., respectively; and at Port Kennedy the maximum temperature is reached between noon and I'' p. m., -while the minimum occurs between 2'' and S*" a. m. We shall now consider the diurnal fluctuation during the different seasons. The time being very limited, the respective curves were only computed for alternate hours.* Spring.

The curve shows a very regular course, and the greatest difference between any observed and computed mean value does not exceed 0o.31. The ' mean range, as derived from the c omputed values, is 40.56; the range, as observed, is by 0o.26 greater. ' Compare the thermal curves for the seasons, as given hereafter in the discussion of the dew-point in the Hygrometri- cal Observations. 30 TBMPERATUEB OF THE AIE Summer. — The form of the curve for summer is very similar to the one for spring. The maxi- mum is reached at noon, while the minimum occurs at midnight, the mean range being 3°. 36. The observed values show a slight irregularity, as the temi)erature is a little lower at I'' and at li'' a. m. than at midnight, the decided rise beginning only at 3*" a. m., lasting till I'' iJ. m., when the maxi- mum is reached, this occurring an hour later than in the computed curve. The mean range, as derived from the observed values, is 3°. 36, differing but slightly from the one given above.

The absolute maximum is the one reached at 4'' p. m., and evidently it is due to. the influence of the sun, which was still above the horizon dur- ing September and the first part of October. We shall demonstrate hereafter that the afternoon maximum becomes most apparent if we investigate the diurnal fluctuation of the temperature dur- ing the former month. Each of these maxima has a corresponding minimum, one of 4o.40 occurring at lO'" a. m., and the other of 4o.37, which is reached at lO'^ p. m. The mean range for this season is Oo.lO only. A comparison of the values actually observed, with the theoretical curve, shows that the first maximum occurs in both instances at the same hour; the same being the case with the second maximum. Winter. — The sun being below the horizon during the greater portion of this season, we can- not reasonably expect a curve of a definite character; besides, there are very sudden changes of temperature taking place, principally due to the alternate action of the equatorial and polar aerial currents, causing the temperature to be very variable, as stated before in the discussion of the annual fluctuation. The analytical elements and expression for the season under consideration were found as follows: n ffn K B„ C„ 1 2 3 +0. 054 +0. 028 +0. 013 +0. 212 +0. 128 +0. 082 +0. 218 +0. 131 +0. 083 o / // 14 17 25 12 20 21 9 30 T=- 20.42+0.218 sin (a;+140 17' 25") + 0.131 sin (2 «+12o 20' 21") +0.083 sin (3 *+9o 0' 30") ic=30o, 60°, AT POLAEIS BAT. 31 The computed values agree very well witb those observed, the greatest difference between the two auiountiug to 0o.25 only. The absolute maximum occurs at midnight and the absolute mini- mum at 6^ p. m., the temperature oscillating in an irregular manner between the two. As may well be imagined, the mean range is very small, not exceeding 0o.78, which is, however, more con- siderable than during autumn.

As may well be imagined, the results are rather discordant in some instances. In order to get a clearer idea of the march of temperature, the computed values were thrown into curves; but we abstain from giving the diagrams here, as they would occupy too much space. To begin with January, we see that both the observed and computed minima occur at mid- night, the curve rising gradually from that hour and reaching its maximum at 5'= a. m. The observed maximum occurs at 2^ p. m., which is more likely than at the hour last mentioned, as it coincides more closely with the time when the sun is nearest to the horizon. We cannot expect, however, to see the hourly variation well pronounced during this month, as the sun only made his re-appearance after the middle of February. As is the case in January, the curve of February shows no decided character. Both the observed and computed maxima occur at midnight, and the minimum at &^ p. m., corresponds in regard to time with the observed value. The curve of March is better marked. The computed maximum occurs at 1'^ p. m., while that observed was reached an hour earlier. Both the observed and computed minima are reached at 6'» a. m. 32 TEMPEEATUEE OF THE AIE In April both tbe observed and computed maxima occur at noon, the minimum at 3^ a. m., and its corresponding observed value an hour earlier. In May tbe maximum is reached at I'' p. m., the minimum at midnight, the observed and com- puted values corresponding with regard to the hour of occurrence. In Jane the observed maximum occurs at 11^ a. m., the computed one an hour earlier, while the observed minimum is reached at 1^ a. m., and its corresponding computed value an hour later. In July both the observed and computed maxima occur at 11'' a. m. The observed minimum is reached at I'' a. m., while the correspoqdlng computed value occurs three hours earlier. In August both the observed and computed maxima occur at l"^ p. m., the computed minimum at 11^ p. m., and the one observed an hour after midnight. Although the computed and observed values for September agree very closely (the difference between the two not exceeding 0°A2), we still see that the observed maximum occurs at 7 a. m., while the corresponding computed value is found to occur at 4 o'clock in the afternoon, thus show- ing retardation of three hours if compared with the maximum of the month last mentioned. Both the observed and computed minima are reached at 11 p. m. Omitting October in this synopsis, we see that in November both the observed and computed maxima occur at IP p. m. The computed mimimum is reached at 5^ a. m., and the corresponding observed value two hours later. The computed and observed ranges are 0o.32 and lo.48, respectively. In December the computed curve passes the maximum at midnight. Both observed and com- puted minima occur at noon. The observed and computed ranges are lo.49 and lo.63, respectively. The analytical elements and expressions made use of are given in the following table, after which will be found the results as derived from the same, together with the observed values: JANUARY. n fln K B„ Cn 1 2 3 —0.22 —0.23 +0.26 —0.27 —0.51 —0. 23 +0.34 +0.61 +0.35 O / " 219 10 12 204 16 25 137 59 35 T=- 22.23+0.34 sin («+219o 10' 12") +0.61 sin (2 ^+204° 16' 25") +0.35 sin (3 £^+137° 59' 35") a;=15o, 30°, FEBRUARY.

The above table contains many discrepancies, as might naturally be expected, all the observa- tions that could be made use of only extending over a period of ten months. These discrepancies will appear even greater if we consider each month separately and analyze the effect of the wind on the temperature in detail, as will be shown in the following synopsis: AT POLAEIS BAT. 37 NORTH WINDS. The few north winds on record have a depressing effect on the temperature throughout the whole year, except during the month of August, when it was found to elevate the temperature 10.5 above the mean. KOETHEAST WINDS. Although the northeast winds have a depressing eifect, except in the mouths of April and August, we still see that in the course of a single mouth the effect cau be either depressing or elevating. At the beginning of Xoi'ej«/*fc the winds under consideration are warm, elevating the tempera- ture 12°; then they become colder, having a depressing effect of 10° during the middle and become as cold as — 20° toward the end of the month. The same effects as stated above will be found in Becemhcr, only less pronounced. In January, at the beginning of the month, the depression below the mean =1°, toward the middle 5°, and at the end of the month the wiud is warmer by 5^. The same takes place in Fehruary, the differences being only —1°, —2° and +2'= from the mean. At the beginning of March the effect is +lo.5, during the middle —3°, and toward the end + 1°. April will be fouud similar to March, the effect being +2o.5, — 2o.5, and +lo.5. May. — At the beginning we see a depression of 7° taUing place; during the middle the ellVct is zero, rising toward the end to +3°. June. — The first portion of the month shows an effect of —1°; increasing toward the middle to —2^.5, while at the end it amounts to +2*^. July. — The beginning of the month shows — 5°; the middle aud the end +2°. August. — Through the whole of August the effect is iwsitive, averaging in the mean '>'''.G. EAST WINDS. During Noremher the effect of the easterly winds will be fouud similar to the northeast, beiug only somewhat smaller, namely, +2'^ for the beginning, — ."i^ for the middle, aud — 7"^ for the end. December.— A.t the beginning of the mouth the effect = + 10o, toward the middle —T', reach- ing — 12° at the end of the month. January gives for beginning 4-2°, middle —3^, and end +1°. February.— At the beginning of the month the effect =—i°, at the middle -f 1", and toward the end -f 7^. 7l/arc/i..— During the whole of tliis month the effect is positive, averaging ia the mean +lo.5. April.— At first we see a depressing effect of —2^, which becomes positive, reacliiiig + i ti^wnrd the end of the month. May.—^o perceptible effect can be found during the beginning of the mouth, but toward the end we get the value of — 1°.3 June shows a negative effect of — 0o.6 through its whole duration. July is positive without any exception, the effect amounting to -fl^.O. Am(/ms*.— There are hardly any easterly winds during this month; the few on record would indicate a rather negative effect. SOUTHEAST AVINDS. November.— Hardly any observations. Effect negative. Deccmhcr.—The few observations would indicate a small positive effect. January.— T^utirelj negative; the greatest depression equaling -4'3. February.— Theve are very few observations on record during this month. The fllect of tlie small number taken into consideration is negative. il/arc/*.— Giving 4-2° with hardly any exception. April.— Is more irregular, being positive by rjo at the beginning, then toward the middle the effect is —4°, vanishing entirely toward the end. 38 TEMPERATUEB OF THE AIR AT POLARIS BAY. ilfaj/.— There is no perceptible effect at tlie beginning; toward the end we get +2°. June.— The only perceptible effect is positive, there being but a few observations on record. July.— The few observations seem to indicate a negative effect. August.— At the beginning of the month the effect is -2°, turning positive toward the middle, namely, +5°, and reaching +8° toward the end. SOUTH WINDS. Up to the mouth of June there are either none or but a few observations on record; after tliis time the effect is positive or zero, (July). SOUTHWEST WINDS. The effect of these winds is positive without any exception, the maximum mean occurring in January ( + 9o.2) and the minimum in August ( + 1°). WEST WINDS. The number of observations being rather small, a somewhat reliable result could only be obtained for February and June. November, December, January, February, and May seem to be positive, the rest negative. NORTHWEST WINDS. Hardly any nortlnvest winds occurred until February. The few results deduced may be found in the table. CALMS. As might be expected, the effect of calms during the cold period of the year must be depress- ing. In summer we miglit exi>ect the contrary. Our observations show a negative effect until March, when it becomes +1°.0, remaining positive for the months of April, May, and July. Dur- ing June the effect is depressing, and the same for August. HOURLY GOEREGTION8 FOR THE PERIODIC VARIATIONS OF TEMPERATURE. The following table, directly derived from Table II, furnishes the means of correcting other incomplete observations, to be taken hereafter at Polaris B.iy, in order to obtain the mean tem- perature of the day : Gorreoiions to he applied to any hourly ohservation. taken at or near Polaris Bay., to obtain the mecn temperatiire of the day. k-^ t^' bcr. 1 H Time.

RECORD AND DISCUSSION OF TEMPERATURES AT POLARIS HOUSE. The following observations of atmospberic temperature were made at Polaris House after the loss of the vessel bad occurred. The latitude of the place was found to be 78^ IS'.O, its longitude 411 41m 4 ^-egt of Greenwich. A glance at the map accompanying this report shows that the sta- tion is situated in a little bight between Cape Hatherton and Littleton Island, named by Kane "Life-boat Cove." The hut in which we spent the winter was situated on a flat spot of the beach only a very short distance from the sea. The box containing the meteorological instruments was fastened to the southern wall of that building. In regard to the topography of the place, we may mention that it was fully exposed to the northwest, west, and southwest, while a range of low hills trended round its northern aud eastern shores. As regards the instruments used, all necessary explanation was given iu the introductory chapter accompanying the Polaris Pay observations. It is proper to mention that during the latter part of February the box containing the instruments was removed from its original place and fastened to the northern wall of the hut in order to pro- tect it from the direct heat of the sun. 40 TEMPERATUilE OP THE AlK NOVEMBER, 1872.

As the daily range of Tolaris House was considered in one of the preceding jiaragraphs, further details in regard to this subject will be superfluous. We shall now proceed to the diurnal fluctuation during the seasons. As the diurnal range of every month was investigated in a similar way, as stated in the course of the Polaris Bay observations, the diurnal range of the seasons was not properly computed. It was thought sufficiently accurate for our present purpose to continue the computed bihourly means of March, April, and May for the representation of spring, and those of December, January, and February for the winter-curve. These curves, with those relating to the seasons of Polaris Bay, will be given hereafter in the discussion of the dew-point.

Both the observed and computed minima are reached at midnight. The maximum occurs almost at the same time as at Polaris Bay, the minimum two liours earlier.

The diurnal range, as derived from the computed values, is lo.58, while the other is O-.G.j greater. In January the observed and computed curves pass through the maximum of — 28o.S8 and — 28°.9G, respectively, at 6'' p. m., while the minimum occurs iu both instances at 6'' a. m. The diurnal range, derived from the computed values, is Qo.SO, tlie other being 0o.93. In February the observed aud computed curves pass through the maximum of — 24o.l3 and —240.11, respectively, at about 8^' a. m., the observed minimum of — 2C°.52 being reached at 8'' p. m., and the corresponding computed value of — 26o.40 between O'' and 10'' p. m. The diurnal range derived from the observed values is 2o.39, while that deduced from those computed is by Qo.lO less. 5i ;>- TEMPERATURE (>E THE AM In March tUe observed and computed maxima occur at uooii and li'' p. m., rc.st>ectively, wbile in both instauces the minimum is reached at 10" p. m. The diurnal range of this month, as deduced from the computed values, is 3o.91, the one observed being V^.W. As the sua was circumpolar from the 17th of April, the diurnal march of the temperature during this month is influenced accordingly. The curve shows a decided rise from midnight till 10" a. m., when both the observed and computed maxima are reached. The minimum occurs at 1!'' a. m. The daily range is about twice as great as during the last month, having risen from 3o.91 to 7o.;3C. The curve of May assumes a more regular character than we have seen hitherto. The time of occurrence of the maxima is noon, while the lowest temperature is reached at midnight. The daily range was 30.5S less than during the last month. THERMIC WIXD-i;(38]:. lu investigating the relation of the atmospheric temperature to the direction of the wind, the same method was used as stated in the discussion of this subject in the course of the Polaris Bay observations.

Calms usually de^iress the temperature. It must be borne in mind, however, that the observations extend over too short a period of time to give any reliable result. Schott finds for the winter half-year at Port Eoulke that the K"., SE., and SW. winds are warm, while northeasters and calms depress the temperature. As the E., S., W., and SW. winds were of rather rare occurrence at Port Foulke, their effect on the temperature could not be ascer- tained during the winter. We noticed, both at Polaris Bay and Polaris House, that the N. and NE. winds were warm at certain times. At the former locality this was found to be the case <«luring September and October, 1871, and formed frequently a subject of discussion. Most likely the wind was bloAving over a body of open Avater, of greater or less extent, to the north of us (though not an open Polar sea), for while on a sledge-journey in September, 1871, we observed a dark water-sky north of Hall's Land, and our late commander noticed the same fact a month later. At Polaris House the north winds were warm during the end of October, but we refrain AT POLAEIS HOUSE. 55 from offering auy explauatioii of this fact, as we noticed iu every instance that the upper clouds had a southern direction; consequently, the elevating effect of these winds on the temperature of the air could not be due to a southerly current of air passing overhead above the northerly. A glance at the above table also demonstrates that the east winds were warm during December, which could be noticed, too, during the preceding month, which is not embraced in our table. A very striking effect of a warm easter was felt in the latter part of October; but as our instruments were not in working order at the time, on account of the general derangement resulting from the loss of the vessel, there are no definite data on hand. It seems to us that at certain times the eitstlerly winds in Greenland show a similar character to the "Foehn" in Switzerland; and since the second German Polar Expedition discovered very high mountain-ranges in the eastern part of this arctic continent, we do not hesitate to pronounce such winds as described hereafter to be true Foehns. The following passage, relating to this subject, is a translation from Eink's admirable work on tlio geography and statistics of Greenland : "The great changes of weather seem to be mostly produced by the warm wind blowing from E. or SE. over the ice-covered interior. This wind, which may be looked for in every month during the year, and along the whole coast, always produces a rise of temperature, which is especially perceptible in winter, when the thermometer may suddenly rise 20° E. It seems to come from the Atlantic, and to produce a compensation between the milder temperature of the latter and the cold regions in West Greenland under the same latitudes. We cannot expect this warm aerial current to come from the south, in which direction the coasts of Labrador and New- foundland are situated, but we may conclude that the next warmer body of air will be met with toward the E. or SE. Considering the phenomenon in such a manner, we can best explain the origin of this warm wiud, which aijparently comes from the great Ice Desert. ''The approach of this warm southeaster is generally marked by the greatest depression the barometer ever shows. It is not a rare occurrence for the column of mercury to fall below 27 inches, and if it gets down as low as 26'".10 or lower, hurricane-like gusts of wind may be looked for. At the same time the sky is slightly overcast, especially with long oval clouds of such a singular bluish appearance that it is scarcely possible to be mistaken iu considering these as precursors of the storm. These clouds appear to hang very high, and never touch the summits of the mountains like those accompauying other storms. Meanwhile, it is dead calm, both at sea and on land; and both in summer and winter the air becomes suffocating, owing to the sudden rise of temperature.- The atmosphere exhibits a remarkable transparancy, and distant land, which under ordinary circumstances is invisible, can be plainly distinguished. Suddenly, the gale begins to rage on the higher mountain-chains; the snow drifts over the highlands, and if an observer be stationed on the ice covering the fiord, near the steep precipices north of Omenak, he can hear the roaring of the storm, while on the ice where he stands the air is still perfectly calm. Sometimes it blows for two or three days or longer, but not constantly, as the wind occasionally falls to a light breeze, blowing now and then in heavy gusts. Sometimes, although seldom, the beginning of the southeaster is accompanied by rain-showers, even in January and February. Then the clouds begin to disappear, and while the storm lasts the sky is perfectly clear. The extreme dryness of this wind is very remarkable; the thermometer, ranging between +30 and 4° E., sinks to 0° if moistened, and the snow-covering of the land diminishes visibly, although not a drop of water is seen trickling from it." In a foot-note Eink remarks that Professor Petersen holds the opinion that this warm wind might possibly be produced by the returning trade-wind, which, however, does not seem to us to be the case, as, according to Eink's own statement, the wind assumes a direction due northeast in the district of Jnlianehaab. 56 TEMPEEATUEE OF THE AIE AT POLAEIS HOUSE. , The following table, derived directly from the table headed "Hourly means of temiierature observed at Polaris House," might be found useful: Corrections to he applM to any hourly ohservation talceii at Folarin Rouse to obtain the mean tempera- ture (if the day.

RECORD AND DISCUSSION OF PSYCHROMETRICAL OBSERVATIONS MADE AT POLARIS BAY. I'N'TRODUGTORY. ' As far as we kuow, none of the \ arions arctic expeditions ever attempted to make psy- clironietrical observations during the cold season of the year, or, if tlie attempt was made, tbe results were so unsatisfactory that the experiments were in a short time abandoned. Still, it is not impossible to make good hygrometrical observations, even at the lowest tem- peratures, provided the observer uses the uecessarj precautions and exercises due patience. According to our experience, no better instruments arc required than two sensitive mercurial thermometers, or, if the temperature be very low, a s^jirit psychrometer. At the same time, it might be well to have one of Eegnaidt's dew-point iustrumeots, to be enabled to test at once the accuracy of the results obtained. Decidedly, however, the simple psyciirometer is to be preferred to the more complicated apparatus; tor, under certain circumstances, as, for instance, during snow-storms, when the snow is diifting, the latter is of but little use, and requires about ten times as long to prepare it for an observation as is needed to read the dry and wet bulb. Besides, at \ery low temperatures, when tbe percentage of relative liuuiidity of the air is small, the rrse of Eegnault's instrument is attended with great difficulties : and we are in doubt whether the results obtained therewitii are more accurate than those derived from the readings of tbe psycbrometer. If the temperature is below — 3(1'^ F., tbe precipitation upon tbe polished-silver cylinder takes place so slowly that much practice is required to determine accu- rately the moment when the first ice-crystals form. Olteu, indeed, we had to m;ilie use of a large lens of considerable focal length to fix this moment ; for the centers of crystallization, when first forming, are almost microscopic. But even in employing lenses of long focus (we used one of about six inches diameter and four inches focal length), the heat radiated by the observer seriously affects the accuracy of the result. Perluips this inconvenience may be overcome by using a telescope of considerable light, and a magnifying-power of about ten or fifteen tunes ; also, we should recommend, if future obser\"ations should lie made, to combine an asiiiracor with the Eegnault apiiaratus, since, at low temperatures, it is extremely unpleasant to force tbe air through the siher vessel by means of a mouth-piece for five or eight minutes. Tbe moisture contained in the warm breath soon condenses in the rubber tube connecting the moutii- piece with the cUinder, and obstructs tbe tube so that but very little air can pass through it. We hardly need to mention that, if an aspirator be used, it should be filled with alcohol rather than water, or with some other fluid that does not freeze at low temperatures. The dew-point instrument used in the course of our observations was naade by Green. The immersed ther- mometer was divided from — s'O'^ to +110° F., and had a length of 13.3 inches. Tbe other one, giving the temperature of the air, measured 8.U inches; its scale-division extending from — 60° to + 110° F. Both instruments had cylindrical bulbs filled with uncolored spirits. The following record contains the observalions made at Polaris Bay ; the hourly series begin- ning November 6, 1871. For convenience, the reductions are given opposite the ])sycbrometer- readings. The first column contains the time; the second, the reading of the dry bulb; the third, the reading of the wet bulb; the column beaded K. H., the relative humidity; the column headed F. v., the force of vapor; and tbe column headed D. P., the dew-point. For temperatures above 3.!- F., the Smithsonian Meteorological Tables by Guyot were used in tbe reduction ; the reduction of readings below tbe freezing-point was made by means of the tables given at the end of this volume. 4 HYGUOMKTIilCAL OBWERAATJONW NOVEMBER, 1871.

In general tlie computed values agree closely with those observed ; the greatest difference being found in Sep- tember, amounting to 0.0047 inch. An examination of the diagram nientioned, or of the above table, demonstrates that the annual curve follows the same law as made out for lower latitudes. The force of vapor is least in Febru- ary, after which time it begins to increase, reaching its maximum in July ; then the curve descends again in a similar manner to that of the temperature.

The computed values agree very closely with the observed ones, the difference beins' only shown in the fourth decimal, exceeding in no instance 0"'.0005. If we compare the thermal curve, exhibiting the diurnal fluctuation with the one in question, we shall see that their maxima and minima coincide tolerably well in regard to time, the computed maximum of temperature being reached at about 11'' a. m., while the minimum occurs at about 1'" a.m. It will be remembered that the observed thermal curve passes through the maximum at ]'' p. m., and throagli the minimum at midnight; showing evidently a more natural curve than the theoretical one. Having discussed the diurnal fluctuation of the force of vapor during the year, it will be of some interest to trace the march of the curve during the different seasons. As each mouth was treated analytically, we thought ourselves justified in deriving the means for the seasons from the com- puted hourly means of the respective months without computing the values for each season, which would have involved too much labor and would hardly have changed the final results more than by four units in the fourth decimal. The curves thus obtained are represented in connection with those illustrating the march of the relative humidity given hereafter in the discussion of this latter subject. In spring the curve shows a very regular course. The maximum, as derived from the computed monthly values, occurs at noon, while the minimum is reached at about IJ'' a. m. The observed maximum occurs at 11'' a. m., and the minimum at midnight. The computed range is 0'".0087 and that observed 0'".0105. According to the corresponding thermal curve both the observed and computed maxima of temperature occur at noon, the computed minimum at 13'' a. m., and the cor- responding value, as observed, an hour earlier. The summer curve is less regular than that of spring, as it shows two maxima, one of which is e\i(leutally abnormal. The absolute maximum (observed and computed) occurs at 2'' p. m., and the secondary maximum at 8'' a. m. Both observed and computed minima are reached at 1'' a. m. Tlic observed and computed ranges are 0"'.011J: and 0"'.0133, respectively. A comparison of the hygrometrical and the thermal curves shows that the maximum of temperature occurs two hours before the maximum of the force of vapor is reached, while the minima coincide very nearly in regard to time. During autumn the computed curve passes through the absolute maximum at 10'' p. m., while the absolute minimum is reached between 11'' a. m. and noon. The differences between the observed and computed values during this season and the one following are not as great as they appear in the diagrams referred to. They actually never exceed seven units in the fourth decimal, and only appear so great on account of the large scale used in projecting the respective curves. The absolnte maxima and minima, as computed, do not coincide in regard to time with those derived from the observed values; the observed curve passing the absolute maximum at 7'^ a, m., and the absolute minimum being reached at lli^ p. m. The considerable difference in time between the occurrence of the actual maximum and the theoretical maximum seems to be due merely to the fact that the difference in the tension of vapor between the absolute computed maximum and the principal relative maximum, Avhich coincides in regard to time with the one observed, amounts only to one unit in the fourth decimal. The computed thermal curve for this seasou exhibits two maxi- ma, occuriing at 1" a. m. and 4'' p. m. (the latter being the absolnte maximum), the corresponding minima being reached at 10" a. m. and 10" p. m., respectively. In general, the thermal and hv^ro- metncal curves agree tolerably well. The range of the force of vapor, as observed, is 0-.0017, while the range derived from the computed values is 0'".0005 only. Owing to the absence of the sun during the greater portion of winter, we can scarcely expect a regular curve for this season, especially as our observations extend over but a comparatively short period of time. It wdl be seen that neither the time of the absolute maximum nor that of tl e absolute minimum is well established. The highest computed tension of vapor occurring during the d ,y IS O-.Oll], ,t being reached at 3" and 5" a. m. ; the lowest is O-.OIOO, to be found during three con- secutive hours, VIZ, at 3", 4", and o" p. m. The curve, derived from the observed means, passes throngh the, absolute maximum of 0-.0114 at midnight, and through the absolute minimum of 0".009i) at - ■ p. m. It will be remembered that the thermal curve for this season is also rather irregular, AT POLAEIS BAY. 57 but still there exists a certain coincidence between tbe maxima and minima of tbe temperature and those oftlie force of vapor; the thermal curve passing through the absolute maximum at mid- night and through the absolute minimum at C' p. m. The range of the tension of vapor as ob- served is 0".0015, 'while that derived from the computed means is 0'".0004 less. We shall see, here- after, that the curves of Polaris Ilouse and of this station show a great resemblance during the season in question.

The computed maximum and minimum of temperature occur at 5'^ a. m., and at midnight, respectively ; the observed maximum coinciding in regard to time with the one com- puted and the time of the observed minimum being 2'^ p. m. Besides the absolute maximum and minimum the hygrometrical curve shows three other relative maxima and as many relative minima similarly to the thermal curve. The range as derived from the computed values is 0'°.0D11, while the one deduced from the observed values is 0'°.0029. In February both the observed and computed maxima of 0'".0100 and 0'".0097 occur at 3'^ a. m., while the absolute computed and observed minima of 0'°.()078 and 0'".0073 are reached at 6'' p. m. The minimum of the force of vapor coincides in regard to time with that of the thermal curve, while the maximum of the latter occurs three hours earlier. The observed and computed ranges are Oi».0027 and 0'°.0019 respectively. In March the computed maximum of Oi''.0122 is reached at 11'' a. m., while the corresponding observed value of 0'°.0123 occurs 2 hours later. The computed aud observed minima of 0'".0091 and 0'".0089, respectively, are both reached at 5'^ a. m. The computed range is 0'°.0031, being O'°.00O7 greater than the observed value. There is a reasonable coincidence between the maximum and minimum of force of vapor and the maximum and minimum of temperature. Evidently the thermal minimum is influenced by the minimum of the force of vapor, which latter occurs one hoar before the former. In April the curve assumes a more regular character, being similar in form to the one represent- ing the diurnal fluctuation during spring. The observed maximum occurs at noon, while the one computed is reached two hours earlier. • The observed and computed minima occur at 2^ and 3^ a. m., respectively, and the observed and computed ranges are 0'".0090 and 0'°.0045, respectively. The observed minima of temperature and force of vapor correspond in regard to time, the same being the case with the maxima. In May both the observed and computed maxima are reached at I'' p. m.; the computed minimum occurs at P a. m., and the one observed Jtn hour earlier. Both the observed and computed maxima of temperature are reached at l*" p. m., and the minima at midnight. The range, as derived from the computed values, is 0'°.0208, while that derived from the observed values is 0'".0123 only. The curve of June is less regular than we might expect. The absolute computed maximum oc- curs at 4'' p. m., while the corresponding observed value is reached an hour earlier. The absolute 9 H 62 HTGKOMBTEICAL OBSERVATIONS computed miuiraum occurs at 2'> a. m., and the correspoading observed value at 11'' a. m., which is evidently abnormal. The computed thermal curve for this month passes the absolute maximum at IP a. m'., and the absoUite minimum at l'' a. m,, while the observed maximum is reached an hour soom-r and the minimum an hour later than the computed values. In July \)oth the observed and computed absolute maxima occur at 8" a. m., the computed abso- lute minimum at 1" a. m., while the corresponding observed value is reached four hours earlier. At first si-ht it migiit seem that the analytical expression for the month in question was not well chosen, but further examination proves that a secondary observed minimum coincides with the absolute one computed. The computed and observed ranges are 0'".0075 and 0'".0111i respectively. The corresponding thermal curve passes through the maximum at 11^ a. m., and through the mini- mum at 1'' a. m. ■ _ _ In August both the observed and computed maxima occur at 2^ p. m., while the minima are reached at 1'^ a. m. The ranges as computed and observed are 0".0229 and 0'".0213, respectively. Tlie maximum force of vapor is reached one hour before the occurrence of the maximum of tempera- ture, while the thermal minimum, as computed, precedes the minimum of force of vapor by two hours, coinciding, however, with the corresponding observed value. In September the observed and computed maxima are reached at 7'' a. m., while the minima oc- cur at 11" p. m. The computed and observed ranges are 0'".002G and 0'".0060, respectively. The thermal curve for this month passes through the maximum at 4^^ p. m., and seven hours later through the minimum. As mentioned before, October was omitted in the analytical treatment because a great number of the observations had to be interpolated^ In November the computed and observed minima occur at IP a. m., and noon respectively, while the computed maximum is reached at 11" p. m., and the corresponding observed value two hours later. The corresponding thermal curve passes the maximum at 1]> p. m., and the minimum at 7" a. m., the computed minimum occurring two hours earlier. In December the computed and observed maxima occur at 3" a. m., and midnight, respectively, and the corresponding minima at 7" and 9" p. m., respectively. The maximum temperature, as computed, is reached at midnight, and the corresponding observed value five hours later. Both the observed and computed minima occur at noon.

The preceding values thrown into a curve result in the following diagram : 65 * According to the above curve, the minimum relative humidity occurs in January and the maximum in May. There is, however, a second relative maximum in Sei)tember and a second relative minimum in June. The computed and observed annual ranges are 35.847 and 33.872, re- spectively. If we compare the annual march of the force of vapor with that of the relative humidity we shall arrive at a somewhat unusual result. We might expect the periodic changes in the force of vapor to follow those of the temperature; in other words, a maximum of temperature ought to correspond to a maximum of force of vapor and to a minimum of relative humidity, while the march of the relative humidity ought to show the contrary relation. The annual curves of tem- perature, force of vapor, and relative humidity represented on one diagram, would show the two former to run nearly parallel with each other, while the other would show the same course only from January until ]May, and from October till December, so that a relative minimum of the relative humidity corresponds to the absolute maxima of both the force of vapor and temperature. To find out how far the maxima of force of vapor correspond in general to the minima of relative humidity we investigated the Toronto Observations,* as well the whole period from 1841 to 1871, as also, some of the years separately. The curves representing a period of 29 years demonstrate that the absolute minimum of force of vapor coincides with the absolute maximum of relative humidity, while, as in our case, only a relatise minimum of the relative humidity correspouds to the absolute maximum of the force of vapor. In 1850 the curve representing the march of the force of vapor reaches its maximum in July, the absolute minimum in December, and a second relative minimum in February, while the absolute maximum of relative humidity occurs iu November and two rela- tive maxima in January and (middle of) August, respectively. The absolute minimum is reached in May, and the two relative minima in October and December, respectively. In 1860 the annual curve of the force of vapor passes through the maximum in August and through the minimum in January, while the absolute maximum of relative humidity is reached in December and the minimum in March; there being, however, a second relative minimum of almost the same value in June. Besides the absolute maximum, the relative humidity exhibits four other relative maxima, occurring in October, August (where a minimum should take place). May, and in the middle of January, respectively, thus showing greater irregularities than the curve of Po- laris Bay. In 1870 there is onlj* a relative minimum of relative humidity coinciding with the abso. lute maximum of force of vapor, while the absolute maximum of relative humidity corresponds almost with the absolute minimum of force of vapor, so that it appears that the curves of Polaris • Abstracts and results of magnetical and meteorological observations at the Magnetic Observatory, Toronto, Canada, from 1841 to 1871, inclusive.

We shall see, hereafter, in the course of tbe discus- sion of the seasons, that the general law can be recogaized beyond doubt in summer, and also, to a certain extent, in autumn, while the curves of winter and spring are less in agreement with the law, although the latter exhibits a very regular course.

There are, in addition to the absolute maximum, two relative maxima, oc- curring at 6^ a. m. and 10i> p. m., respectively, the former corresponding in regard to time with the absolute maximum observed. The two relative minima are reached between 8^ and 9^ a. m., and at 6^ p. m., respectively. AT POLAEIS BAT. 67 A comparison of the carve in question witb that illustrating the diurnal march of the tension of vapor shows that the absolute maxima coincide within l^^ in time, the maximum of tension of vapor occurring later than that of the relative humidity. The Toronto observations, comprising the period from 1842 to 1848, show that the maximum of force of vapor has its corresponding minimum of relative humidity, and vice versa. This, however, is not the case if we examine the curve of January during the same period, for we shall find that a relative maximum of relative humidity corresponds to the absolute maximum of the force of vapor, while the July curves for the same period are more in accordance with the general law deduced for lower latitudes. In order to discuss the diurnal variation of the relative humidity during the different seasons, the computed means of the respective months constituting the respective seasons were used, in- stead of computing each season separately.

It will be noticed that during the afternoon the curves run nearly parallel, while this is less the case during the rest of the day. The maximum of relative humidity is reached at noon and coin- cides with both the maxima of force of vapor and of temperature.

The computed curve passes through the maximiim at 9'' p. m., the corresponding observed value occurring one hour earlier, while the computed minimum is reached at Q^ a. m., and the observed minimum at i^ a. m. The ranges, as derived from the computed and observed values, are 0.75 and 1 70, respectively. Besides the absolute maximum, the curve shows two relative maxima at about half an hour after noon and S^ p. m., respectively. It will be seen that the absolute minimum of relative humidity coincides with a relative maximum of force of vapor, while the two relative maxima correspond to the absolute minimum and a relative minimum, respectively. The absolute maximum of relative humidity lies between the absolute maximum of force of vapor and a relative minimum, and the two relative minima coincide with two relative maxima of force of vapor.

Besides the absolute maximum and minimum there are two relative maxima occurring at 4^^" a. m. and noon, respectively, and two relative minima whicb are reached at 7^ a. m. and about S^i" p. m., respectively. The computed absolute maximum does not coincide in regard to time with its observed value, although it corresponds to a relative maximum, while the absolute minima as observed and computed coincide within half an hour. The computed and observed ranges are 3.81 and 4.44, respectively. A comparison of the two hygrometrical curves shows that the absolute minimum of relative humidity coincides with a relative maximum of force of vapor, and the absolute maximum, as computed, with a relative minimum occurring about 4J hours after the absolute minimum is reached. The relative minimum of relative humidity at 7'^ a. m. corresponds to a relative maxi- mum of force of vapor, and the relative minimum taking place between 3^ and 4^^ p. m. corresponds to the absolute minimum of force of vapor. The two relative maxima of relative humidity at 4^'' a. m. and noon, respectively, correspond to a relative minimum of force of vapor and to a relative maximum, respectively.

The computed minimum occurs at 2^ a. m. and the corresponding observed value an hour later. The computed and observed ranges are 4.0 and 4.9, respectively. The absolute minimum of relative humidity coincides in regard to time with the absolute minimum of the tension of vapor, the same being the case with the respective maxima. In February both observed and computed maxima occur at 10'' a. m., the computed minimum at midnight, and the corresponding observed value two hours earlier. The observed and computed ranges are 5.8 and 4.6, respectively. The maximum and minimum of the force of vapor being reached at 3^ a. m. and 6'> p. m., respectively. In March both the observed and computed absolute maxima occur at 10'' a. m. and the minima at 4^^ a. m. The observed and computed ranges are 13.17 and 11.93, respectively. The maxima and minima of the force of vaper coincide very nearly in regard to time with those of the relative humidity. In April both the observed and computed absolute maxima are reached at 6*^ a. m. and the minima at 8^ p. m., while the tension of vapor reaches its maximum at noon and its minimum at 3^ a. m. The observed aud computed ranges are 11.1 and 8.3, respectively. In May both the observed and computed maxima occur at noon, almost coinciding in regard to time with the maximum force of vapor. The computed minimum is reached at G^ p. m., one hour before the corresponding observed value, while the tension of vapor is at its minimum at 1^ a. m. The observed and computed ranges are 4.5 and 3.6, respectively. • In June the observed maximum is reached at 11'' p. m., the one computed occurring at midnight. The theoretical curve passes through the minimum at noon, while the actual minimum is reached an hour earlier. The observed and computed ranges are 4.3 and 3.0, respectively. According to the computed curve the maximum of the force of vapor occurs at 4'^ p. m. and the minimum at 2^ a. m. Considering the march of the relative humidity by itself, independent of the force of vapor, we see the curve to follow the same general law as made out for more southern stations. In July both the observed and computed maxima take place at 4'' a. m., while the computed miuimnm occurs at 4'' p. m. and the corresponding observed value one hour later. The observed and computed ranges are 3.3 and 2.7, respectively. The force of vapor reaches its maximum at 8'' a. m. aud its minimum at P a. m. In August the observed and computed maxima and minima occur at 2'^ a. m. and noon, respect- ively. The computed range is 11.6 and that derived from the observed values is 0.5 less. The maximum of the force of vapor is reached at 2'' p. m. and the minimum at 1*" a. m. In November both the computed and observed maxima occur at ^^ p. m., the observed minimum at 4'' a. m., and the corresponding computed minimum four hours later. There is, however, a computed relative minimum, corresponding in time to the absolute minimum as observed. The computed and observed ranges are 2.3 and 4.5, respectively. The maximum of force of vapor is reached at 11'' p. m. and the minimum at 11'^ a. m. In December the absolute computed maximum occurs at 8'^ p. m., corresponding to a relative observed maximum, but the absolute observed maximum is reached at noon, the difference between the absolute and relative maxima being 0.4 only. The computed minimum is reached at 8'' a. m. aud the corresponding observed value one hour later. The computed and observed ranges are 7.9 and 6.7, respectively. The computed curve of the force of vapor passes the maximum at 3'' a. m and the minimum at 7'' j). m. AT POLARIS BAY.

Taking into consideration the fact that Hall's Basin and Kulie.son Sti;iit were hardly ever entirely frozen oi.er. and that the lanes of open water were con- stantly shiftii is. we have to expect that the same wind may produce contrary effects: that, for instance, a wind blowing from northeast may increase the amount of moisture contained in the air during one day while it diminishes the same during another. The analytical expression for the above wind-rose is as follows : ^"= + 0.33 + 2.66 sin (x + 239- 45') + 0.45 sin (,2 x + 9- 2^ ) A comparison of the. following values computed bj" means of this formala with those above given will show that the differences are rather considerable, as can scarcely be expected other- wise : X. y.

We content onrselves with giving merely the effect of the wind, whether increasing ( + ) or decreasing ( — ), irrespective of the ratio of increase or decreasi:'. If be noted in any of the columns, it signifies that the winds were either entirely wanting during the period under con.sidera- tion or of too short duration to give any result. Each mouth is divided into three equal paits, and the influence of the direction of the wind on the relative humidity during each of these periods is indicated either by a positive or negative sign or by zero : 76 HTGEOMETRICAL OBSERVATIONS Months.

During the different months, the temperature of the dew-point is above the annual mean in May, June, July, September, October, and November; while it is below the same during the six remaining months. Likewise, the mean temperature of the dew-point is below the annual meau in winter and spring, and above the same in summer and autumn. If the curves representing the annual fluctuation of the temper- ature of the air and of the dew-point were represented simultaneously ou one diagram, we should perceive them to run nearly parallel from the latter part of March till the middle of September, while they would diverge more or less during the rest of the period.

According to the formula the temperature of the dew-point reaches its maximum of — lo.28 at about 10'' a. m., and its minimum of — 3o.2« at about 1'' a. m., thus exhibiting a diurnal range of 1°.98, which is by 0o.l2 greater than the diurnal range of the tempenitiirc of the air. The cor- responding thermal curve passes through the maximum at ll"" 10'" a. m., and through the minimum at 0" 56-° a. m. The differences between the computed temperature of the dew-point and the computed tempera- ture of the air are as follows : Oh 6.30 eh 5.97 Noou. (1.48 6h 1;.

It will be seen that the greatest difference between the temperature of the air and that of the dew-point during the twenty-four hours exists at 2^ p. m., being 6o.59 ; while the smallest, of 5o.7G, occurs at about 10"^ p. m. 80 HYGEOMETEIOAL OBSERVATIONS The following table coTitains the hourly variation of the temperature of the dew-point during the four seasons. The seasons were not computed according to the formula, but it was thought sufficient, as the time at our disposal was ratlier limited, to combine the computed hourly means of the respective months constituting tiie dittercnt seasons, and to take the mean of tiie same. .S[)rint;.

It will be seen that the computed temperature ot the dew-point reaches its maximum between 1" and 2*' p. m., while the minimum occurs at 2^ a. m. The maximum and minimum, as observed, occur at Z^ p. m. and S^ a. m., respectively. The thermal curve, and that represeuting the fluctu- ation of the dew-point, run almost parallel with each other ; they approach each other most closely at 8" a. m., and recede most from each other at 2'^ a. m. The probable error of any single obser- vation is 0°.10, that of the mean being 0°.02.

The computed curve reaches its maximum at 2'» p. m. and its minimum at 1'^ a. m.; the range being 1°.15. The observed curve passes through the maximum at lO'' a. m., while the time of its minimum coincides with that of the computed value. The thermal curve and the curve showing the fluctuation of the dew-point approach each other most closely at midnight, while they are farthest apart at noon.

The computed curve passes through the maximum at 0'^ a. m. and through the minimum at 5^ a. m., the latter coinciding in regard to time with its cor- responding observed value, while the observed maximum occurs at I'' a. m. Besides the absolute maximum there are four relative maxima, occurring at &^ a. m., 9"^ a. m., noon, and between 4'' and 5^ p. m., respectively, while the relative minima are reached at about 1^^ a. m., lOJ'' a. m., 1^^ p. m., and at 7^ p. m., respectively. The observed and computed ranges are 0o.53 and 0°.66, respect- ively. The thermal curve and the curve representing the diurnal fluctuation of the dew-point approach each other most closely at midnight, as was the case in summer, while their greatest sep- aration occurs at 10'' a. m. It remains now to consider the diurnal fluctuation of the dew-point during winter. The following differences between the temperature of the dew-point and the temperature of the air were found to exist : 0" 2 4 6 8 10 Noon. 2" 4 6 8 10 100.76 10°.63 100.49 10O.05 10°.32 10°.32 10O.62 10O.43 10°.58 10°.12 10O.26 10-.26 84 HYGEOMETEICAL OBSERVATIONS The following diagram exhibits the curve of the dew-point and the thermal curve during winter : Diurnal fluctuation of the temperature of the air and temperature of the deivpoint during winter, 1871-'72. ■i-%Kt WMmsMomi ^a/ F f »*■ ',J1' ^>:f4l>1?f^)lii liHiiini While, daring the last season, the diurnal range of the temperature of the dew-point was greater than that of the air, we now see the contrary to take place. The temperature of the dew-point, according to the computed curve, reaches its maximum at 6^^ a. m. and its minimum at 4:^ p. m. Between the absolute maximum and minimum the curve is seen to oscillate in an irregular manner, thus exhibiting a number of relative maxima and minima which sometimes correspond to similar maxima and minima of the thermal curve. The difference between the temperature of the air and the temperature of the dew-point is greatest at midnight and least at 6^ a. m. The computed and observed ranges of the temperature of the dew point are 0^.59 and lo.35, while those of the air are 00.78 and 0O.83, respectively. In order to discuss the diurnal fluctuation of the temperature during each of the different months, each month was treated analytically. The following analytical elements and expressions were used in this computation : January. n In K B„ c„ 1 2 3 -f 0.19 — 0.17 + 0.01 — 0.21 — 0.22 — 0.17 + 0.27 + 0.28 + 0.17 138 6 6 216 49 44 178 21 28 D= — 33.20 + 0.27 sin (x -f 138^ 6' 6") + 0.28 sin (2 x + 216° 49' 44") + 0.17 sin (3 x + 178° 21' 28") x=15°,30°, . . .

The observed mini- nmm ocenrs in January, while the computed curve passes through the minimum in February, or. rather, about the I'Oth of January. An examination of the thermal curve during the wiuter-half- year sliows that January was the coldest mouth, although the computed curve reaches the miui- mum in February, so that the thermal and hygroraetrical curves are in conformity.

Diurnal fuctuatlon of farce of rapor — ivintcr-haJf-year. M ii jNuuu i.^ In general, the computed and observed values agree pretty closely, the greatest difference be- tween the two not exceeding 0.0006. The computed curve passes the maximum of 0.0271 at about 1^^ a. m., and the minimum of 0.0239 at about llji^ p. m., thus exhibiting a range of 0.0052. Besides the absolute maximum there are two relative maxima of 0.0268 and 0.0256, respectively, occurring at 6^ a. m. and 7'^ p. m., respectively. The two corresponding relative minima of 0.0264 and 0.0254, respectively, being reached at about 71'' a. m. and G^' p. m. An examination of the corresponding thermal curve shows that the absolute maximum occurs at 2^= p. m. and a relative maximum at S^ a. m., which latter, however, is merely accidental ; the minimum temperature during the period in question being reached at midnight. In order to investigate the diurnal fluctuation of the force of vapor during winter the means of the computed values for December, January, and February were taken, given in the following table, with the observed values and the differences between the two : AT rOLARIS HOUSE.

The curve resulting from the above values will be found in the discussion of the diurnal fluc- tuation of the relative humidity giveu hereafter, where the two hygrometrical curves are repre- sented simultaneously. As was found to be the case at Polaris Bay, the curve now in question is rather irregular. It passes through the absolute maximum of 0.0121 at 6'' a. m., while the minimum of 0.0104 is reached at S^ p. m., the range being 0.0017 only. Both the computed and observed absolute maxima and minima coincide in regard to time. Besides the absolute maximum and minimum there^ are a number of secondary maxima and minima, as a glance at the above table, or at the curve referred to, will demonstrate. The corresponding thermal curve passes the absolute maximum at miduight and the absolute minimum at noon, there being, consequently, no coincidence of the maxima and minima of temperature and force of vapor in regard to time.

It may be seeu that the computed curve passes the maximum of 0.0438 at 2'> p. m., while the minimum of 0.0362 is reached at midnight, thus showing 136 HYGROMETEICAL OBSERVATIONS a rauoe of 0.007C. Besides tlie absolute maxinmm there is a relative (accidental) maximum of 0.0410 taking place at about 7>^ a. m. The maximum and minimum, as observed, occur at 3^ p. m. and 1" a. m., respectivelv, coinciding in regard to time pretty closely with their corresponding com- puted values. The corresponding thermal curve passes the maximum about half an hour past noon and tlie minimum at midnight. At Polaris Bay the maxima of temperature and. force of vapor occurred nearly at the same time (noon), while in this instance the maximum of force of vapor suffers a retardation of about "2i hours. Pop the better uuderstanding of the diurnal fluctuation of the force of vapor during the two seasons in question, and during the winter-half-year, we shall now consider the dinrnal fluctuation during the different mouths on record.

The ranges, as derived from the computed and observed values, are 0.0050 and 0.0067, respectively. The maximum of temperature is reached at midnight, while the minimum occurs at 2'^ p. m. In January the curve is rather irregular, showing two maxima of 0.0051 each, occurring at 9^' and 11'' a. m., respectively, while three minima, of 0.0043 each, are reached at 4'', S^, and 7'', p. m. The range is very small during this month, amounting to 0.0008 only. The corresponding thermal curve passes through the maximum at Q^ p. m., and twelve hours later through the minimum. In February the observed and computed maxima of 0.0083 and 0.0081, respectively, occur at ll'' and lO'^ a. m., respectively, the minima, of 0.0065 each, being reached at I'' a. m. and midnight, respectively. The maximum temperature during this month is reached at 8'' p. m., while the mini- mum occurs at noon. The curve representing the diurnal iiuctuation during March coincides well with the thermal curve. The observed and computed maxima of force of vapor occur at 1'^ p. m. and about three- quarters of an hour past noon, respectively, while the minima are reached at 11'' p. m. The maxi- mum and minimum temperatures occur at 2'' p. m. and 10'' p. m., respectively. The April curve exhibits a very regular course ; the maximum of 0.0357 being reached at 2'' p. m., while the minimum of 0.0246 occurs at 2'' a. m., the range thus beiug 0.0111. The observed maximum of 0.0351 coincides in regard to time with the corresponding computed value, while the observed minimum takes place about one hour before the occurrence of the one computed. It will be remembered that during this mouth the maximum temperature was reached as early as 10'' a. m., while the minimum took place at 2'' a. m. In May the computed curve passes through the maximum of 0.0879 at 1'' p. m., the minimum of 0.0775 being reached at midnight, thus giving a range of 0.0104. The maximum and minimum of temperature occur at noon and midnight, respectively.

According to the preceding table the relative humidity is above the mean in March, April, and May, while it is below the same during the three remaining months. As may well be expected, it is less in winter than in spring, it being below the mean during the former seasou and above the same during the latter. At Polaris Bay the minimum relative humidity was reached in February, while in this case it occurs in January. A comparison of the march of the relative humidity and force of vapor during the winter-half- year brings out the fact that the minimum relative humidity ia January corresponds to a relative maximum of force of vapor, while a relative maximum of relative humidity in February coincides with the minimum of force of vapor. From the middle of February until May the two carves run nearly parallel. The mean relative humidity as observed at Polaris House and Polaris Bay during the winter- half-year compares as follows : December. January. February. March. April. May. Winter. Spring. Mean. 66.600 40.319 48.513 48.039 69.270 74.912 51.811 64.074 57.942 54.673 47.525 .53.351 56.204 77.686 83.666 51.849 72.519 62.184 Polaris House Polaris Bay It will be seen that the relative humidity as observed at Polaris Bay was greater in every month, with the exception of December, than at Polaris House ; the greatest difference occurring in May, the least in February. 19 H o * 142 HTGROMETRIOAL OBSBRVATIOKS DIURNAL FLUCTUATION OP RELATIVE HUMIDITY AT POLARIS HOUSE DURING THE WINTER-HALF-TEAR.

The above values thrown into a curve result in the following diagram : Diurnal fluctuation of relative humidity at Polaris House, winter-half-year 1872-'73. The computed curve passes through the absolute maximum ot 62.986 at 2>' 5" p. m. and through the absolute minimum of 57.134 at 6^ 21'» p. m., thus exhibiting a range of 5.852. Besides the absolute maximum there are two relative maxima of 61.6565 and 60.570, respectively, occurring at 7'» 59".5 and 2^ 30'>i.5 a. m., respectively, the corresponding relative minima of 60.230 and 60.203 respectively, being reached at 4'' 28- and lO-^ 54- a. m., respectively. If we compare the curve under AT POLAEIS HOUSE. 148 consideration witli that representing the diurnal fluctnation of the force of vapor, vre shall see that the absohite maximnm of the latter, occurring about 1^ a. m., corresponds almost to a relative mini- mum of relative humidity; while the absolute minimum, which is reached at 11^ p. m., corresponds nearly to a relative maximum of relative humidity. It will be remembered that the thermal curve passes through the maximum at 2- p. m. and through the minimum at midnight.

Most likely, however, this is merely accidental, as during the rest of their march the two curves do not show the relation as traced in lower latitudes in general, and, also, at Polaris Bay, during summer. At Polaris Bay the absolute maximum of relative humidity during the season in question was reached at 8^ p. m., which is almost the time of the absolute minimum at Polaris House, while the relative minimum of the latter station coincides within two hours with the absolute minimum at Polaris Bay; the minimum at Polaris Bay being reached earlier.

The features of the curve exhibiting the diurnal march of the relative humidity are less regular than those at Polaris Bay. The curve shows two maxima of 66.29 and 64.08, respectively, occur- ring at about 2f' p. m. and about Q\^ a. m. ; the two miuimaof 62.31 and 63.34, respectively, being reached at about l^^a. m. and about %^ a. m., respectively ; consequently, the range equals 3.98, being 0.96 smaller than during winter. At Polaris Bay a certain parallelism of the two curves in question was noted, and this may be observed here even to a greater extent, as the maxima of force of vapor coincide almost with the maxima of relative humidity ; and the same will be seen in regard to the minima.

The ranges, as derived from the computed and observed values, are 3.176 and 4.538, respectively. In December the computed curve passes through the maximum of 68.325 at about 6'' a. m while the corresponding observed value occurs one hour earlier. The computed minimum of 63.008, is reached at 6^ p. m. and the minimum, as observed, two hours later. The range, somewhat larger than during the preceding month, is 5.317. The maximum and minimum force of vapor occur at 6'' a. m. and 6^' p. m., respectively, while the thermal curve passes through the maximum at mid- night and through the minimum at 2^ p. m. In January both the observed and computed maxima of 46.252 and 45.266, respectively, occur at 8'' a. m., while the observed and computed minima of 35.881 and 37.680 are reached twelve hours later. Owing to the small range of force of vapor the curve representing the fluctuation of the latter during this month is rather irregular, while the thermal curve passes through the maximum at 6^ p. m. and twelve hours later through the minimum, the tropical moments of the latter coin- ciding within about two hours with those of the relative humidity. In February both the observed and computed maxima of 49.600 and 49.248, respectively, are reached at 6'' a. m., while the observed minimum of 46.578 occurs at 10'' p. m., and its correspond- ing computed value of 47.062 near midnight. The ranges, as deduced from the observed and computed means, are 3.022 and 2.186, respectively. The maximum temperature of this month is reached at 8'' p. m., while the minimum occurs at noon ; and the maximum and minimum tension of vapor are reached at lO'' a. m. and midnight, respectively. The theoretical curve representing the diurnal fluctuation of March passes through the maximum and minimum of 52.971 and 44.209, respectively, at 2'' p. m. and lO'' p. m., respectively, coinciding in regard to time with the maximum and minimum, as observed, and exhibiting a range of 8.762. The maximum and minimum farce of vapor are reached at 1** p. m. aud 11'' p. m., respectively, while the thermal curv^e passes through the maximum at 2'' p. m., and through the minimum at 10'' p. m. In April the observed and computed minima of 65.377 and 65.968, respectively, occur at 0'' and 2'' a. m., respectively, while the observed and computed maxima of 71.637 and 71.604, respectively, occur at 2'' and about 4^ p. m., respectively. The range, as derived from the computed values, is 5.636, while that deduced from those observed is a trifle smaller. The maximum and minimum tension of vapor occur at 2'' p. m. and 2'' a. m., respectively, while the thermal curve passes through the maximum as early as 10'' a. m. and through the minimum at 2'' a. m. In May both the observed and computed maximum occur at 8'' p. m., the former amounting to 76.835, the latter to 76.782. The observed and computed minima of 72.574 aud 73.079, respectively, occur at noon and about 11'' a. m., respectively. The computed and observed ranges are 4.261 and 3.703, respectively. The maximum tension of vapor daring this mouth occurs at P p. m. and the minimum at midnight, corresponding in regard to time almost with the tropical moments of tem- perature during the period in question. ATMIG WIND-ROSE OF POLARIS HOUSE. The two following tables exhibit the influence of the wind on the relative humidity of the air.

If the time at our disposal had been less limited we should have investigated the influence of the direction of the wind on the elevation or depression of the force of vapor, which might, perhaps, have yielded some better results. The atmic wind-rose of Polaris House may be represented by the following analytical expres- sion : H= + 0.32 -f 2.74 sin (x + 223" 43') -f 0.43 sin (2 ac + 339° 27'.)

At Polaris Bay the greatest difference was found to exist in December, amounting to 110.93, being somewhat greater than at this station. In December, April, and May the difference between the temperature of the air and the temperature of the dew-point is below the mean, while it is above the same during the three remaining months. Further comparison shows that during winter the difference under consideration was greater at Polaris Bay than at Polaris House, while in spring it was less at the former locality than at the latter. If we calculate the difference during the winter-half-year at Polaris Bay we shall have 9'=.17, being 0o.S5 greater than the difference as made out for the more southern station. We shall see, hereafter, that the greatest amount of atmospheric precipitation at Polaris House took place during the month of May, when the difier- ence between the temperature of the dew-point and that of the air was smallest.

We shall now consider the diurnal fluctuation during winter and spring separately. The \alues for these two seasons, given hereafter, were not properly computed according to the formula, but we were satisfied to combine the computed hourly means of the respective m Mu*hs conftitutiug one season, taking their meau instead of the computed values. 252 HYGROMETKICAL OBSERVATIONS Diurnal fuctuutum of the temperature of the dew-point during ivinter at Polaris House.

The curve passes through the absolute maximum of — 150.48 at about C' a. m. and through the absolute minimum of — 19O.03 at about 6'' p. m., oscillating between several relative maxima and minima. The maximum and minimum temperatures during this month occur at midnight and 2'' p. m., respectively. In January the differences between the computed temperatures of the air and those of the dew- point are as follows : C" 2 4 6 8 100.60 9°. 79 90.70 100.08 IQo. 21 8 10 11-. 78 110.47 Mean. 100. 53 10 Noon. 21^ 4 6 90.99 90.94 100.34 100.96 ir-\ .52 The curve passes through the absolute maximum of — 39o.20 at about noon and through the absolute minimum of — 40O.77 between 8" aud 9'' p. m., exhibiting a range of lo.57, being by lo.98 less than during the preceding month. Besides the absolute maximum and minimum there are several relative maxima and minima, as a glance at the general table will readily show. The maximum and minimum of temperature are reached at 6'' p. m. aud &" a. m., respectively. For February the following differences between the computed temperatures of the air and the computed temperatures of the dew-point were deduced : Ot" 2 4 6 8 110.55 100.86 100.86 100.02 90.96 10 Noon. 21 4 6 8 10 Mean. 80.20 70. 69 80.79 lOo. 05 10-. 74 lio. 40 10-. 95 lOo. 17 The maximum temperature of the dew-point of — 34o.2i is reached at 11" a. m., while the curve passes through the minimum of — 3Go.C5 between 5" and G" a. m., thus exhibiting a range of 20.44, being somewhat greater than during the preceding month. The maximum and minimum of temperature are reached at S" a. m. and 8'' p. m., respectively.

The curve leinvsentiug the diurnal fluctuation of the dew-point passes through the maximum and minimum at li'' p. m. and 10'' p. m., respectively, clusely coincid- ing in regard to time with the maximum and minimum of temperature. For April we get the following differences : 0" 2 4 6 8 10 Noon. •>'' 4 fi 8 10 Moan. C°. 61 0°. 00 6°. 09 0°.96 7". 09 7". 80 7'-\'.y.t 0^ S2 .5°. 7-i 0.17 7 -'.-JO 7-. 70 0-. 'J8 It will be seen that the greatest difference between the temperature of the dew point and that of the air occurs at noon, and the least at 1'' p. m. The range during this mouth is 2-. 25, being a little greater than during March. The maximum and minimum temperatures of the air during the period in question occur at 10'' a. m. and 2'' a. m., res[)ectively, while the maximum and minimum of the dew-point are reached at 3'' p. m. and 2'' a. m., resi)eetively ; the minima of the two elements coinciding in regard to time, whik' the maximum temperature of the air is reaehed five hours pre- vious to the maximum temperature of the dew-point.

The diurnal curve passes through the absolute maximum of 13'3.6I: at about 9'' a. m. and through tli solute minimum of 10 -.77 at 1'^ a. m., thus exhibiting a range of 2'3.87, being 0-M)l less than that of the temperature of the air. Tbe maximum temperature of the air occurs at noon, while the minimum is reached at midnight.

For measuring the amount of raiu and suow, two ombrometers were used, one supplied by the United States .Signal Service Weather Bureau and the other by the Smithsonian Institution. The tormer consisted of a copper cylinder about 18 inches long and 3 inches in diameter, provided with a funnel whose diameter was four times as great as that of the cylinder. The Smithsonian gauge consisted of a plain cylindrical tube of tin, 12 inches long and 3=^ inches in diameter. Since the difiiculties to be contended with in the measurement of very small quantities of rain-fall with any degree of accuracy are very great, various methods of proceeding were adopted. During our residence at Polaris Bay the larger rain gauge was always in use, being placed in an open sjiace 30 yards east northeast of the observatory, either resting directly upon the ground or elevated upon an overturned boat, whose height was scarcely IS inches. If the snow-fall was accompanied by wind, then the snow was not caught in the gauge itself but collected from the surface of a board, which was brushed clean after every fall. The funnel was removed from the cylinder and the latter was turned over, mouth downward, and pressed against the board ; a sheet of stiff paper was then slipped under the mouth of the cylinder, and the latter raised from the board. This pi'ocess was repeated more or less frequently according as the quantity of snow was small or large ; then the measure was placed either in warm water or near the stove until the snow was completely melted. The measurement was made by means of a wooden rod which was dipped into the collector arul allowed of correct readings to the hundredth part of an inch. Of course, the result thus obtained Jaad to be divided by the number of times the cylinder had been dipped in the snow, as above explained. In taking each mean the third decimal was retained. During our second winter the smaller rain-gauge, furnished by the Smithsonian Institution, was made use of. The following table contains the observed quantities of moisture precii)itated. Besides the number of hour* during which it rained or snowed, the character of the fall is also given: I indicates a light and h a heavy snow-fall. The next column indicates the quantity of snow in English inches. Whenever, in this column, a query is found, it is intended thereby to denote that the quantity was imperceptible or immeasurably small. The next nine columns show the wind that was blowing at each hour at which precipitation occurred, including calms. The last column contains the mean velocities of the winds.

During the seven months in question, it snowed at the former station during 43ii hours and at the latter during 335 only. While the amount of snow measured at Polaris Pay from November, 187J, till June, 1872, is .314 only, that measured at Polaris House is li .319, if expressed in volume of water. The maximum of snow-hours at Polaris Bay was noted iU'April, viz, 14S, and at the other station in May. viz, 117; the amount of snow corresponding to both periods is 0'".063 and 0'°.374, re- spectively. The minimum of snow hours of any month is 7 hours at Polaris Bay (December, 1871), and at Polaris House it is 11 hours (March, 1873). It is true that the amount of snow could not always be ascertained accurately. If we should assume that the amount which actually fell at Polaris Bay was double that measured (though that assumption would be too great), and should, therefore, double the value previously given, it w"ould still only give 1">.354, including the rain that fell duriii- July and August. That, under such cir- cumstances, the glacial period of Northern Greenland cannot ajtproach a maximum, but that the glaciers must be on their decline, is evident. In the next volume, containing, among others, the geological results, we shall dwell at greater leni^th on this subject. Hy geometrical Obsei'vations. Tension of Vapor inEiiglisli Inches. July . JSnglisli Bictie s ■ ATMOSPHERIC PRESSURE 1 A P RECORD AND DISCUSSION OF THE OBSERVATIONS ON ATMOSPHERIC PRESSURE MADE AT POLARIS BAY. Ill connection with tlie observations on winds, recorded in the preceding part, we shall now give those on atmospheric pressure. The hours of observation are the same as mentioned before, and all the omissions occurring in the preceding observations also occur here. The instruments used were of ditf'erent character and manufactured by different makers. We h;i(l three large aneroids, two of which were made by Casella aud the other by Beck, London; three nmrine-baronieters by Adie, reading to 0'".005, and three standard barometers, of Fortin's construction, manufactured by Green, reading to 0'".002. Besides the instruments mentioned, the e>vi>edition was supplied with a number of very superior pocket-aneroids by Green, Beck, and Casella, which, however, ■were only used by traveling parties or for deducing the refraction in connection with the temperature for astronomical purposes. When at sea on onr way north in ISTl, the Adie and one of the aneroids were read, which were kept on the after-deck in the same louver-boarded box containing- -the rest of the meteorological instruments. The cistern of the Adie was about nine feet above the snrl'ace of the sea, the aneroid being on the same level. In some instances this height may have varied more or less, according to the quantity of coal and provisions on board the vessel. After our arrival at Polaris Bay the three Fortius* were hung up on the western wall of the observatory, thirty-four feet above the level of the sea and at the height of the eye. In order to protect the instruments from the direct radiation of the warm stove, a small oblong box, somewhat longer and a little broader than the barometer, was firmly secsred against the wall behind each instrument. The barometers were suspended on heavy rods about live inches long, on which the suspending-rings might slide with ease, the rods being turned up at the ends to prevent the instruments from slipping oif. The barometers remained in the box, the iloor of \\hich was kept closed until the time of observation, when it was opened and the barometer to be read taken by the upper end of the tube and moved toward the free end of the rod — that is, toward the observer. Xo special precaution was taken to secure perfect perpendicularity of the iiistrunii'uts, they being constructed in such a manner as to take their equilibrium themselves. When the ixory point in the cistern was brought in contact with the surface of the mercury, artifi- cial light was used, either a short candle or a small oil-lamp, made for the purpose. In taking the leading and making the adjustment the usual precautions were taken. In the course of the winter the mercury contained in the cisterns of the different instruments had to be cleaned repeatedly, in which instances the respective barometers were compared with others before and after the perform- ance of the operation. From November C, 1871, till June liL', isTli, Green's barometer N"o. 947 was read; if other instruments were made use of, their readings were referred to the barometer above mentioned. Hefore leaving Washington City, Mr. Meyer couipared another barometer, supplied by the Signal- Oriice, and also manufactured by Green, with the standard at the United States Naval Observatory. -Vfter our arrival at winter-quarters the corrections of the other barometers were ascertained by moans of the instrument compared by Mr. Meyer with the standard at Washington. As these comparisons were lost, we deduced the correction of Green's No. 947 for a mean atmospheric press- ure of i:0'".5, which was found to be -|-0*".051. We managed to bring this instrument back to * For the description of tlie FortiD-Green barometer, compare Smitliaouian Miscellaneous Collections (148), Directions for Meteorological bsrivations, and the i;e,i;i3try of Periodical Phenomena. Washington : Government Printing Office, ieT2. 4 ATMOSPHERIC PEESSUEE Wasbingtou, aud through the kindness of the Superintendent of the United States Xaval Observ- atory, we were enabled to take a number of comparisons with the standard above mentioned. The corrections, as deduced subsequent to our return, are: At inches. Coircction. 30.4 +0.040 30.0 + 0.042 2().S +0.045 29.5 +0.053 As the greater number of our observations had ah'eady been reduced at winterqaarter.s with tlie application of +0'".051 as correction, no use was made of the above figures, the mean correction, as found subsequent to our return, differing only by — 0'".00G from that first applied. From June 22, when the vessel was freed from the ice, Casella's aneroid No. 1210 was used. Tliis instrument being divided to 0'".010, the divisions are large enough to enable the observer to estimate, by means of a magnifier, with some degree of certainty, the tenth part of a division, thus giving a very satisfactory result. Whenever an opportunity ofl'eied the aneroid was compsired with one of the mercurial instruments, and corrected accordingly. The following record contains the reduced hourly observations. Those made with the mercu- rial barometer were referred to the temperature of the freezing-point of water by means of tlie Smithsonian Meteorological Tables. Besides this, the observations were corrected for an elevation of thirty-four feet and for the temperature of the air.

The aneroid obscr\-ations are only corrected for indc.Y erior. Xo correetioii was applied for the influence of gravity, and as the instrument u.sed was compensated, a correction for temjierature wfis deemed unnec(\ssory. AT POLAEIS BAY. 5 Date. NOVEMBER, 1871.

An examination of the Port IJoulke observations shows that at this locality there is also a relative maximum in jS!"ovember. At Eensselaer Harbor there is also a slight indication of a secondary maximum corresponding to the one under consideration, and the same is the case at Sabine Island, where a relative maximum occurs iu the same mouth as at Polaris Bay. The curve of Port Kennedy shows similar features. The annual fluctuation, as represented above, is the result of the combined pressure of the dry air with the pressure of the aqueous vapor. By eliminating the influence due to the latter, we get the following values : Annual fluctuation of atmospheric pressure corrected for the influence of force of vapor. Mouths. Inches. Months. Inches.

The above observations, extending over but a comparatively short period of time, no general conclusions can be drawn from them, because the atmospheric pressure is very variable from year to year, as an examination of the observations made at Eensselaer Harbor will readily demou.strate. It will be seen, for instance, that the barometric mean of January, 1855, differs by 0'".631 from that of the same month in ISoi; the difference in Febrtiary being smaller, althougli exceeding 0'°.3. Eeturniug to our table, we see that at Sabiue Island the observed maximum occurs in MarcU, at Polaris House and at Port Kennedy in April; while in Baftiu's Bay and at Keusselaer Harbor it is found in May. Both at Polaris Bay and Port Foulke the absolute maximum, as observed, occurs in Kovember, during which month the respective comj^uted curves show a secondary maxi- mum, as stated above. In Baffin's Bay the minimum was observed in January, at Port Kennedy and Sabine Island in July, while at Eensselaer Harbor it occurred in September. At Port Foulke the month of lowest pressure is October, and at Polaris Bay it is December. At the two stations last mentioned the highest and lowest pressure occur in two consecutive months. At Polaris Bay the absolute maximum in November is followed by the absolute minimum in December, and at the other locality the absolute minimum of October precedes the absolute maximum, which is reached in the following month. THE DIUENAL FLUCTUATION OF ATMOSPHBEIC PEBSSUEE AT POLAEIS BAY. The diurnal fluctuation of atmospheric pressure is best represented by the deviation of the hourly means from the annual mean. Taking, therefore, the annual means of every hour of the day, we obtain the followiug elements for the analytical expression : a, = — 0. 00243 Si = + 0. 003,24 Bi = 0. 00405 c, = 323: 3' 10" flj = — 0. 00079 is = _ 0. 00295 Bj = 0. 00305 Co = 195: 51' 40" 03 = — 0. 00OG5 63 = — 0. 00133 B3= 0.00148 C3 = 200'^ 13' 40" «< = — 0. 00022 h = +0. 00175 B4 = 0. 00177 Cj = 352- 48' 30" The analytical expression, therefore, assumes the following form : B=29.y76y+0.00405 sin (a;+323o 3' 10") + 0.00305 sin (2 .( + 195:' 51' W) +0.00148 sin (3 a;+206o 13' 40")+0.00177 sin (J- .t+352o 48' 30") 22 ATMOSPHEKIC PEESSUEE Tbe period is referred to (»'' as its beginniug, and the angle ,*■ increases at tlie rate of 15" per hour.

By the aid of the diagram the abso- lute maximum will be found to occur at about 9" a. m., while the absolute minimum is reached at about 51^ p. m. If we consider the minima occurring respectively at about 11^' SO-" a. m. and at 9'" p. m. to be accidental, then we shall have a maximum at about 10" p. m., and a secondary minimum at about midnight. Among the different arctic stations our curve shows the greatest resemblance with that of Sabine Island, where (according to the formula) the forenoon maximum is reached at 10^' 31" and the evening maximum at 9"^ 45™, while the two minima occur at 3'> 40™ a. m. and at 4" 35-" p. m., respect- vely. At Port Foulke, (compare diagram on page 217, loc. cit.,) there is a very slight indication of a maximum at about 7^^ 30-" a. m., w^hile the absolute maximum occurs at about 6^ 30™ p. m..; at Eeusse- laer Harbor the highest pressure during the day is reached at about 10'^ p. m. and at Port Ken- nedy and Baffin's Bay at about 71^ 30™ p. m. The principal minimum at Port Foulke occurs at about 31" a. m. At Rensselaer Harbor the (secondary) minimum is reached about 4'' a. m. and at Port Kennedy and Baffin's Bay at about i^ 30™ a. m. At Polaris Bay the diurnal range is 0'°.0142, to which we add the following values for com- parison : Inches. Rensselaer Harbor 0.010 Port Foulke 0.017 Sabine Island 0.00.^ Baffin's Bay 0.028 Port Kennedy 0.048 The theory established by Daniell, and favored by quite a number of modern meteorologists, that the diurnal fluctuation would vanish almost entirely in high latitudes, does not find any sup- port in the table above given. Most likely the theory does not hold good in this instance, as the dis- 24 ATMOSPHEEIC PEESSURE crepancies seem to increase with the growing nnmber of observations, which circumstance ought to induce us to abandon this theory, unless it be confirmed by subsequent observations. Between the latitude of Port Kennedy and that of Eensselaer Harbor, except at Sabine Island, a decided decrease evidently takes place; but at Polaris Bay, which is situated in the region where the diurnal range was supposed to vanish, we inud the diurnal fluctuation to be greater tbau at Eensselaer Harbor, situated three degrees to the south of this station, and almost as great as at Port Foulke. After having corrected the diurnal fluctuation for the influence of the force of vapor, the hourly values will run as follows: Diurnal Jhict nation of afmoq)Jicric 2))rssnre at Polaris Bay, corrected for force of vapor.

For the sake of comparison the following table was formed, containing the diurnal fluc- tuation of atmospheric pressure for six stations situated in tlie arctic regions, and arranged according to decreasing latitude.

In constructing the curves representing the diurnal fluctuation during the latter, we used the computed values for each of the three different months constituting one season, and took the mean of the same. This was done to save the labor involved in establishing the analytical expressions for the respective seasons, as for certain reasons we had thought it proper to treat each month analytically; but we abstain from giving these results, they being without any value for the present discussion. Owing to the shortness of the period over which the series of observations in question extends, the law governing the diurnal fluctuation during the year can scarcely be recognized in the curves exhibit- ing the diurnal fluctuation of the difterent seasons. In winter the absolute maximum of 29'°.8184 occurs at about .5'' p. m., and the absolute minimum of 29"'.7071 at midnight, the curve thus show- ing a range of 0™.0213, oscillating irregularly between the hours of highest and lowest pressure. AT POLAKIS BAY. 25 In spring the curve is less irregular, passing through the maximum of 30'".1542 at about 6'' 45™ a. m. and through the minimum of 30'".1332 at 7^' p. m., its range differing only by two units in the fourth decimal from that of the preceding season. In summer the maximum of 29'°.894:9 is reached at 6^ a. m. and the minimum of 29'".8767 at midnight, the range being 0'".0182. The autumn curve shows a decided maximum of 30'".0726 at about 5^ a. m. and a well-marked jninimum of 30".0536 at about 11'' p. m., exhibiting a range of 0'".0190. During each season the diurnal range is greater than that of the year, the smallest range occurring in summer and the greatest in winter, the former differing by 0'°.0040 and the latter by 0"'.0071 from the diurnal range during the year. The following table contains the maxima and minima of atmospheric pressure as observed during each month. It need hardly be mentioned that the values given are reduced to 32° F., and to the level of the sea : Monthly extremes. Months. January.. February . March.... April May June July August- ..

To obtain the dependency of the atmospheric pressure upon the direction of the wind the fol- lowing method of discussion was adopted : The monthly means of atmospheric pressure for the hoars midnight, 6'^ a. m., noon, and 6'' p. m. were subtracted from the observed readings at those hours for every day of the year, (us far as they were on hand,) and the differences thus obtained were considered to be due to the direction of the winds prevailing at the hours O'', C' a. m., 12'^, and &' p. m. These differences were found to be positive and negative for the same directions of wind; the mean of the differences are then 4 AP 26 ATMOSPHERIC PEESSUEE cousidered as the mean effect of the winds from the respective directions, which is either positive or negative, i. e., elevating or depressing, as shown in the table below : s.

The Fortin- Green barometer was suspended on the southeastern wall of our hut, protected by a box, the lid of which was only opened when a reading was taken. The cistern of the instrument was 8.5 feet above the sea-level. For further reduction of the readings, referred to 32° F., the following table was used : Correction due to 8.5 feet elevation above mean sea-level.

Most likely (if we may judge by the tropical moments of the neighboring stations), the absolute maximum of the year is that of 29'". 9344 during jSTovember, which mouth was omitted in the table above given. In regard to the minimum we feel less certain, as the minimum pressure during the year occurred at Port Foulke in September and at Van Eens- selaer Harbor in the same month, while at Bafflu's Bay and I'ort Kennedy the mouths of lowest ])ressure during the year were January and December, respectively. According to appearance January seems to exhibit the lowest mean pressure at Polaris House duri4ig the year, unless the minimum should have occurred during the time between June and Xon ember, which is not at all likely. If we separate the pressure exerted by the vapor contained in the atmosphere from tliat ex- erted by the dry air, we get the following result: JldUths. Deccii:l)er JaDuary T 1 1 lueues. 1 Mootbs.

Both the computed and observed maxima coincide in regard to time; uot so, however, with the minima, as the observed minimum occurs about two hours later than the oue computed by means of the formula. Besides the absolute maximum, there is a secondary maximum of 30'".01C4 occurring at about 4'' p. m. Between the absolute and relative maximum the curve passes through a relative minimum of 30'".011i6 at about 1'' p. m.; another relative minimum occurs at about -'' a. m. The diurnal range during the winter- half is 0'^0127, being somewhat greater than at Port Foulke aud somewhat smaller thou at Rens- selaer Harbor, as made out for the whole year. 6ap 42 ATMOSPHERIC PEESSUKE Coirectiiig tlie iirecediiij;- table, exbibiting the diurnal fluctuation of atmosplieric pressure, for the tension of vapor, we get the following values: JJiurna} fluctuation (■orrcvtcil for tension of vapor.

After having given the diurnal fluctnation during the winter-balf-year, a few remarks maj' be made regarding the diurnal fluctuation during winter and spring properly.* The winter curve shows similar features to that representing the diurnal fluctuation during the six months in question; the absolute maximum of L'9"'.8762 occurring about S'' a.m. and tiie absolute minimum of -O '.77o8 at about 10'' p. m. Besides the absolute maximum there is a secondary maximum of i"J".8G30, occurring at about 4'' p. m. Two secondary minima of 29'".8135 and 29'".7871, respectively, take place at about noon and 2'' a. m., respectively. The diurnal range during this season is 0"'.1024. The spring curve is less regular than that representing the diurnal fluctuation during the preceding season. The absolute maxinjnm of 30'".02C1 occurs at about C' a. m. and the absolute minimum of 30'".0016 at about 6'' p. m., the curve thus- sbowing a range of 0'".02J:.5, being 0"'.0779 smaller than during winter.

In general, the range at Polaris House is smaller than it was found to be at Port Foulke and at Rensselaer Harbor during the same seasons, where storms were more frequent than at our second winter- quarters. BARIC WIND ROSE. To investigate the influence of the wind on the atmospheric pressure, we proceeded exactly as we did in coustructing the thermic wind-rose. • The above results were iliiliiced from the computed bihourly meiui-i of each mouth, combincil for the respective seasons. For reasons mentionoil before, we abstain from giving the analytical expressions for the respective months in (luestion. AT rOLARIS HOUSE.

It will be seen that, after balancing the resulting average effect for the different directiiMis, all the winds, except those blowing from E., SW., and W., seem to have a depressing ollccl. Tak- ing, however, into consideration the fact that the series of observations is rather short and that some of the winds are of rare occurrence, the above results cannot be very reliable. The following table, derived directly from the table giving the hourly means of almospheric pressure, may be used to reduce hourly barometric readings tal2 —0. 0035 —0. 0079 +0. 0047 +0.0010 WINDS 1 w RECORD AND DISCUSSION OF WINDS OBSERVED AT POLARIS BAY. INTEODUCTORT. If we are. not mistaken, the Polaris Expedition was tlie Orst to bring back a continuous series of aneiuometric observations from the arctic regions, furnishing thus more accurate results than have hitherto been obtained by the common method of estimating the force of the wind. We were supplied with three anemometers (Eobinson's), of which two were made by James Green at Xew York, and the other by Casella of Loudon. Besides these instruments, we had two small Casella current-meters, frequently used in hospitals to measure the amount of air passing to or from the wards. One of the anemometers was mounted near the observatory on a pole about six feet high; and a glance at the ground-plan of the observatory, given under the chapter "Temperature of the Air", will give all the explanation that will be needed in regard to its i)osition. Like the rest of the obser- vations, those on the wind were made hourly ; in every instance the indication of the dial of the anemometer was noted, and also the velocity of the wind at the moment of observation determined. The latter was done by observing how much the index of the dial advanced during a certain inter- val of time, or by counting the number of revolutions performed by the cups say during ten or fif- teen seconds, assuming that the arras would have to revolve fis'e hundred times to show a differ- ence of one mile in the dial-reading. In some instances, Oasella's pocket-instrument was used. In order to give some idea of the winds during September and October, for which period of time the regular record is lost, we insert three daily observations for the former mouth that were saved. The column headed "Dir." gives the direction of the wind; The one headed " Vel." gives the velocity at the time of observation ; and The column headed "Dist.", the distance traveled during the last twenty-four hours. The hours of observation are : 7^ a. m., 4^' p. m., and 11^' p. m. The winds for October were taken from the log-book. The time of observation is not stated there, nor were the velocities measured. The force was given according to Beaitfort's scale, and was converted into miles afterward. The regular hourly observations began November C, 1S71, and were continued until we left Polaris Bay. The direction of the wind was recorded from eight points of the compass. No wind-vane was used ; the direction being derived from fixed points on shore, the bearings of which had been determined. The iirst column of the hourly series contains the direction of the wind ; the second, the velocity at the time of observation ; and the third, the distance traveled during the last hour.

The direc- tions are, as needs hardly to be mentioned, those from which the winds are blowing. If, therefore, at the station of the observer, a free point is imagined to be subjected to the simultaneons action of all tiie winds blowing during tlie year, it would move with the velocity of 11392.7 miles per hour in a direction S 40° W. From January to June, the direction oscillates between NE and N; being alaiost exactly NE in March and nearly N in January and April, having a tendency to veer a little toward the west during the latter month. During July, August, aud September, the current is from SW; and in October, November, and December from NE. The last horizontal column of our first table contains the sums of the velocities of the winds from the eight principal directions, as observed during the year. In order to obtain the mciin annual velocities, these sums have to be divided by the number of observations for each direction, as shown in the following table: Directions. N Sum of velocities 320.1. .5 Number of observations ■ 243 Mean velocity ; 13.18 XK E SE S SW W NW ■29.301.4 7651.9 2161.3 7;;4. 5 11712.5 609. 9 1692. 4 1773 1494 568 206 11.50 213 254 17.76 5.12 3.80 1 3. 50 , 10. 18 2.86 7.72 The number of observations during the whole year is therefore = 5901, and, consequently, tbe annual mean velocity of the resulting direction = ^=f^-- = 1.95 miles per hour. In the annexed diagram, the observed velocities of the wind are represented by a continuou!^, and the mean velocities by a dotted, curve. AT POLAEIS BAY. 37 DURATION OF STORMS.

This storm 'svas the severest experienced at Polaris Bay; but un- fortunately tbe record is not complete, as it was utterly impos- sible to reach the anemometer after 10'' a. m., November 20, when the record ends. The duration of the storm cannot be de- termined very well on account of tbe loss of some of the docu- ments relating to this subject, but probably it was not less than eighty hours. A great portion of the ice filling Robeson Strait and Hall's Basin at the time was set adrift. Oscillation of the barometer about 0.2 incb; temperature falling from -fl^'.O to — IS^.l; relative humidity decreasing from SCto4ri; sky over- cast. Barometer rose about 1 inch, oscillating between 29.27 and 30.20; temperature rising from — 1- to -|-10°; sky cloudy. Barometer rose about 0.3 inch; tempei'aturo pretty steady at — 17'^; relative humidity rising first from 61 to 72, decreasing then to 33. Barometer ialling about 0.09 inch; relative humidity decreasing; cloudy. Oscillation of barometer small; temperature rising from — 17"^ to — 15°; relative humidity increasing at the beginning of storm from 40 to 55, decreasing then to 33; cloudy.

From the 17th to the 18th, the barometer fell about 1 inch. Wljcii the storm set in from the SW, the barometer stood at 28.983, fall- ing slightly at the beginning, rising again till 1'' p. m. (19th). At e"" a. m. on the same day, the wind veered through AV to X\V, and began to blow from N)] at noon, increasing rapidlj' in veloc- ity. During the time it vras blowing from SW, the temperature was rising, falling during the NE wind. Sky mostly overcast. Barometer pretty steady at 30.14 ; oscillation small.

Barometer not much affected. Barometer fell 0.3 inch. Barometer fell 0.3 inch. Barometer hardly affected. As will be seen from the preceding table, there are twenty-one storms on record, nineteen of which blew from NE, two from SW, and one from N. January was the stormiest month tiic number of storms being five. In July, there is but one on record. In October, we have four instances when the estimated velocity of the wind was considered to be forty miles per hour ; but, as the A-elocity was based on estimation only, no use was made of the values given, because, in iustances when the temperature of the air is rising, the observer is very apt to underrate the velocity, and vice verm, as an examination of both Kane's, Hayes', and McOlintock's observations will show. RECORD AND DISCUSSION OF WINDS OBSERVED AT POLARIS HOUSE. The anemometer used at Polaris House was the same as mentioned before, and tbe observa- tions were made in tbe same manner as described above. Tbe instrument was mounted about 20 yards from the water's edge, 5i feet above the ground, and the winds had free access to it.

In December the case was found a little different, however, as nearly twice the quantity passed over the latter place. In general, more air passes from the NE over Polaris House than over Polaris Pay, althouf;li we never experienced such high winds from this direction at the former place as at the latter. It will be seen that the quantity which passed over Polaris Bay in March is nearly twice as large as that over the other station during the same mouth. The difference nearly vanishes in Januaiy. In regard to the easterly current, exactly the contrary takes place, except iu May, when the amount noted at Polaris House is a trifle larger ; while during the rest of the period under consider- ation it isdecidedly less at the latter locality. The same may be noticed in regard to the 8B winds; the quantity of air passed from this direc- tion being, without any exception, larger at Polaris Pay tlian at Polaris Uouse. If we except January, the quantity of air that passed from the S is larger at Polaris House than at Polaris Bay. This fact is very strilving iu x\pril, when the proportion becomes 1400 : 0. In regaid to the quantity of air that passed froui S\V, nearly the coutrary takes place from what we noticed concerning the NK winds. In three instances, viz, in December, Februiiiy, and May, the qnantity ])asse,(l over Polaris P-ay is by far greater than that passed over tlie other station. During January, it is nearly equal at both localities. Th(^ W winds are very rare, and the greatest quantity of air that passed during any mouth in the period under consideration does not exceed fifty miles; Avhile, during Deceml)cr and January, there were no westerly winds at all on record lor Polaris ITonse. The (juantity of air passed from the N\V, though vei'y small, is more considerable than that from the diicction last mentioned ; during e\ cry month, however, it is deeidedlj' larger at Polaris Bay than at I'olaris House. As stated before, we have discriminated between calms and absolute calms; compiising under the former all those cases when the wings of the anemometer were not in motion at the moment of observation, the reading of the, dial, however, having inei'caseil since the last observation; whereas, during our absolute calms, the hand of the dial had not moved at all. The following table contains the number of calms and absolute cabns recorded both at Polaris B;iy and J\ilaris House from November till June.

At Polaris House, we find for the m;i\-imum of absolute calms 'I'l'l (in January), ami at Polaris Bay 57 (iu April) only. If we do not discriminate between nominal calms and absolute calms, we find that at both stations the total calms occur more frequently in spring than iu winter, wjiieh is in conformity with the observations made at various other northern stations.

May 10 An examination of tlie storms observed at Polaris Bay and at Polaris House shows that gales were less frequent at the latter locality than at the former. The maximum velocity of the wind observed at Polaris Bay is fifty-eight miles per hour; whereas at Polaris House it never exceeded forty -eight miles. If we except the gale lasting from November l.S-L':j, 1871, the record of which is not on hand, the maximum duration of any storm observed at Polaris Bay will be found to be 52 hours, and at I'olaris House 48 hours only. The number of storms observed at Polaris Bay, compared with that of Polaris House, is as follows: — Mouths. November Decciiilrer ., . .Ian nary I\;bru.arj'- ... March April Mav T'cdaris Polaris J!av. llonsr. During the same period of time, the expedition under Dr. I. I. Hayes recorded fourteen storms, two of whicii were blowing from SW and the rest from ]S"E, with the exception of one, during which the wind occasionally blew from SW. It should be remembered, however, that in this case the velocity was only estimated, and not based on actual measurement. At Rensselaer Harbor, the number of storms for the same period of tiuie is five only ; the velocity of the wind being also estimated. Sir Leopold McCliiitock observed sixteen storms at Port Kennedy from the 1st of November, 1858, to the 1st of June, 1859, thirteen of which were from NW, one from W, and two from NE. His register kept in Baffin's Bay gives twenty, mostly from NW, for the same period of time. ROTATION OF STOUJIS AND OP WINDS IN GENERAB. Two of the storms recorded at Polaris House seem to show a decided rotation, according to the law known as Dove's. In the first instance (December 7 and 8), the wind, blowing from SW, was freshening to a gale, veering through NW to N after the storm had abated. The storm recorded on May 10 shows also a decided rotation from NE to SW. Those observed on November 14 and April 2G blew from SW and NE respectively; freshening in both instances after the wind had been blowing at a moderate rate from the respective directions for some time. 9 w G6 WINDS The storms observed at Polaris Bay are jjartly revolving storms. Those veering decidedly according to the law are as follows : — jST^ovember 28 and 29. — Wind veered from E to iSW, with occasional squalls from NE. January 3.— Wind sliifted from XE to E, with squalls from X. January 1-4. — Wind veering from NE to E, with an occasional squall from SW. February 18, 19, and 20.— Wind veering from SW, through W and NW, to NE. March 12. — A liesheniiig northeaster, veering to E after tbe storm abated. June 27 and 28.— Before the beginning of the gale, the wind shifted from XW, through N, toNE. July 24.— Wind sliifting from XW to N. Consequently, one-third of the storms recorded at Polaris Bay follow the law of gyration; besides, we have two instances, namely, December 28 and May 10, in which it is doubtful whether the wind shifted contrary to the apparent motion of the sun or not. The twelve remaining storms show either a decided retrograde motion or they are winds that had been blowing for some time, either from XE or from SW, freshening to storms. The following ones belong to the first kind: Xovember IS to 23.— Wiiul veering from SW, through E, to XE. December 10 and 17. — Wind veering from XE to X, springing back to NE when the storm was abating. January 10. — ^Vind sliifting from E to XE. February 11 and 12.— Ycering from E to XE. February 22. — Shifting from E to X, veering back to XE. March 10.— Wind shifting from E to XE. May 4 and 5. — Veering from SE, through E, to XE., whereas, ou Xovember 12, January 11, January 31, February 9, March 20, and June 21, the wind had been blowing from XE some time previous, freshening until it attained the velocity of a storm. Uow far the winds iu general follow the law of rotation may be seen from the following two tables, exhibiting the number of changes of the wind at Polaris Bay and at Polaris House. The columns headed + contain the direct, and those headed — the indirect, changes. In making out these tables, the changes were counted, the counting being renewed after each calm.

As may be seen from the following table, tbe motion in winter is decidedly more rctrogiade at Polaris Bay than at Polaris House ; althougb tbe cjuantity of air tbat passed from tbe direction of the prevailing wind is greater at tbe latter station tbau at tbe former during tbe same season.

The winds blowing from X, S, and AV seem to have a greater tendency to veer direct thau the others. At Polaris Bay, this will be found to be tlie case with XI\ ]\ and SW, and at Polaris House with S, wiuds. According to all appearance, the winds are sometimes of a very local character. Fre(]uently one would remaik that it in Polaris Bay* the wind blew with considerable velocity- I'rom the north- east, the lower clouds hanging apparently over the coast of Grinnell Land, just opposite, indi- cated by their course a ditferent direction of the wind. Sometimes such notable calms prevailed at the Polaris Bay observatory that the index of the anemometer did mit move one-tenth of a mile in the course of several hours, while seven or eight miles farther south, according to the testimony of pedestrians, an unpleasant sharp breeze prevailed. Daring onr sledge-journey south, iu the spring of 1872, we noticed very striking ditterences in the directions of the snow-drifts that had accumulated during the winter; and while on our return to winter-(juarters we were detained by a severe gale from the southwest, the direction of the wiud at Polaris Bay was at the same time from the northeast. "While on the boat-party toward the north, we had the same experience ; namely, we found at every projection of the coast we doubled local deviations of the wind. At our second winter-quarters, at Polaris House, the wiud would sometimes attaiu a velocity of thirty miles or more, while complete calms prevailed at the Eskimo settlement at Sorfalik, a certain distance south of our hut. A fact noticed by almost every one of our crew is this: that it at Polaris House there was hardly a breeze stirring, a pretty sharp wind began to spring up as soon as we doubled Cape Alexander. Generally, this breeze was from the south, following the direction of the coast, and seeming to come from Poulke Fjord, iuto which a glacier discharges. * Cnnip.lT.' till- iliscussioQof the wiuila obsctveJ at Xr-ivuian's Buy, given lu-roartLT in tbo part contaiuiug tlie " ilL'teorijIcisical Observa- tions taken at Si,a." SOLAE EADIATIOK. 1 S R SOLAR RADIATION AT POLARIS BAY I^TEODUCTOllY EEMAKKS. A short time after the sun had made his re-appearance, two black-bulb thermometers were exposed, both at Polaris Bay and at Polaris Jlouse, to measure the amount of solar radiation. One of these thermometers was in vacuo ; the other having a naked bulb of blackened glass. The instrument in vacuo, manufactured by L. Oasella, London, is a mercurial maximum ther- mometer, inclosed in a glass tube; the cylindrical bulb and a part of the stem being covered witli lamp-black. The length of the thermometer is 15 inches, and it is graduated from 0^ F. to 212^ F. The naked-bulb instrument is a common thermometer with blackened bulb ; the upper part of tlie stem being inclosed in a glass tube, to ])rotect the graduation against moisture. Both instruments are mounted on small stands, as represented in the annexed diagram. Tiie upper portion of the stands on which the instruments rest can be turned in azimuth, and is very slightly inclined ^toward the horizon. The instruments are about 12 inches above the ground, which is covered with white cotton sewed to a piece of cotton-flannel, to which two small bars of lead are fastened, to prevent the cotton from being blown away by the wind. The regular observations recorded hereafter begin March 4, ending June 21, 1872. The first column of the following table, headed r, contains the readings of the thermometer iiti-avito; the second, headed /; those of the naked bulb; the third, headed J> f, the difference between the temperature of the air in the sliade and the tem])erature as indicated by tlie instrn- ment in vacuo; the fourth, headed J)f, contains the difference between the temperature of the air ill the shade and the temperature as indicated by the naked-bulb thermometer.* In the last column, the' amount of clouds covering the sky at the moment of observation is given ; indicating a perfectly clear sky, ^ that the sky is less covered than one-fourth, etc. " .Siiiiii'Uiiif'H Df is foinul tri be nefjativr, tlic uniirotccted tlicriiioiiict,cr iiffiiig us wct-biiUi. 4 SOLAR EADIATION MARCH, 1872. ]>;iv.

The followiug table contains the ditterences between the readings of the bhick-bnlb ther- mometer in vacuo and those of the temperature of the air from the time tlie sun became circum- polar till the observations were abandoned. For convenience, tbe observations were divided into groups of weeks. Underneath the values mentioned, the sums of the same are to be found, with their corresponding means. In cases where observations are missing, — for instance, during hr avy snow-drifts, — no means are given, as we do uot think ourselves justified in resorting to interpola- tioD. No use was made of the readings of the unprotected instrument; it being influenced too much by wind and atmospheric moisture, causing it sometimes to read even lower than the ther- mometers exposed in the shade. 10 s K SOLAK EADlATIOy.

If we compare the amount of solar heat conveyed to the earth in instances when the suu has the same altitude, we obtain the following series, iu which, for example, the sun has the same altitude at noon as at a later date at midnight. With north latitude, the altitude of the sun at noon = 90 —

Hence, for 0.001 inch increase or decrease of the force of vapor, the radiation will increase or decrease 0o.37 F. At Polaris House, the difference mentioned above is 24o.5, and the differeuce in the force of vapor 0.0063 inch. Hence the coefficient of radiation for 0.001 inch of the force of vapor = 0^.40 F., which latter value may be adopted for the present. 11 s R 82 tSOLAE EADIATIOX— RESULTS.

After having applied the correction due to the influence of the force of vapor, the difference becomes even greater, equaling 3°A F., so that the force of vapor alone cannot explain this circumstance. If we had used different instruments at the two stations, we might suppose that the vacuum surrounding one thermometer might have been more complete than that of the other; but the observations at both stations were made with one and the same thermometer. A greater number of ob.servations on this point would be desirable, and we would recommend to the United States Signal-Service to supply their observers with black-bulb ther- mometers in vacuo; and, although the method of measuring the intensity of solar radiation by means of a thermometer is a very rough one, it would, nevertheless, yield some interesting results^ especially as some of the meteorological stations of the Bureau above named are situated on high mountain-peaks. * Halley, a discourse couceruiug the proportional licat of the sun in all the latitudes, etc. Philosophical Trans- actions, vol. 17.

The scarcity of the curuulo-stratus and the 'total absence of nimbus are readily explained. A fact worth noticing here is that quite frequently the cirri were observed to descend or to form in the lower regions; that is, in those of tlie cumulus, or even stratus. The explanation of this phenomenon is easy. A most striking instance of extremely low-hanging cirrus-clouds was observed at Polaris House on May 20, 1873. At 7'' 30'» a. m., a halo was noticed round the sun, as represented in the following diagram : Tlie outer circle was apparently resting on the ground, and its diameter, as measured by a prismatic compass, was found to be 82° 15'; that of the inner one being 48°. The inner edges of loth circles were colored faint red, and were sharply defined. The outer edges did not show the pale-blue tint, as usual, but a dim yellowish-white, with an illdeiined outline. Through the mass of both rings, a chain of hills could be seen, a little over a mile distant. At the time the halo was noticed, the atmosphere was filled with minute i(e-spicula\ no PACE OF SKY AND STATE OF WEATHER. A little before 8'>, the upper part of tbe balo disappeared, and soon after the rest of the inner circle faded away entirely. At about the same time that part of tbe outer circle apparently resting on tbe ground became invisible, and the upper (left-hand) portion was dissipated under the influence of the wind, forming distinct cirrus-clouds. OBSERVATIOFS ON OZONE. loo OBSERVATIONS ON OZONE MADE AT POLARIS BAY AND POLARIS HOUSE. INTRODUCTOlfY. The expedition was supplied witb several boxes of Sclioeiibeiu's and ^MoH'at's ozone test-pajiers, aceoitipaiiied by their respective scales. In the observations recorded hereafter, onl^- Schoeiibeiii's paper was used, as that made according to MoS'at seemed to be spoiled or badly prepared, giving giving very discoidant results. Tlie ])aper was exposed in a cage consti ncted of fine wire-gauze, and placed in the same louver- boarded box containing the various thermometers and the psychrometer. The slips were expused every morning at S'', and left in the (■age until the same time the next day, when they were taken ont, dipi)ed in ice-water, and comparf d with the graduated scale. Sometimes we exposed three or four i)apers, ime of which was taken in after the regular interval of time had elapsed, whereas the others were left exposed for three da.\'S or longer. In the latter case, it was sometimes found that the strips exposed more than twenty-fnur hours were less tinted after having been moistened with water tiian those which had been left in the cage for a shorter time. The papers weie exposed a long time in order to aecumalate the small amount of ozoni' cou- taioed in the air which would not act ou the paper if left outdoors for a day only. In some instances, the slips that had been exposed longer than twenty-four hours showed a darker color than those which had been in contact with the air for a day only; but the intensity of color shown by the former was never equal to the sum of the intensities of all those exposed a day each during the given time In the following tables, the first column contains tbe days of the month ; the second, the amount of ozone accumulated during each twenty-four hours; the third, the mean relative humidity during the same lapse of time; the fourth and the fifth, the prevailing direction of the wind and the distance traveled during the said period ; and, in the last column, the amount of clouds is to be found.

ABSTEACT OF METEOROLOGICAL RECORD KEPT ON BOARD THE UNITED STATES STEAMER POLARIS DURING HER PASSAGE FROM NEW LONDON TO ROBESON CHANNEL. The following record is aa abstract of the meteorological register kept during the passage of the vessel from New London, Conn., to Robeson Channel. In several of the preceding parts of this volume, we took occasion to refer to this document, which furnishes the means to complete most of the meteorological observations for September, 1871. In regard to its arrangement, no further explanation will be needed. We merely limit ourselves to the statement that the velocity of the wind was measured by means of an anemometer, or by one of Casella's current-meters, pre- viously alluded to. The anemometer was placed on the hurricane-deck, where it was deemed to be exposed to the free action of the wind. Up to July 23, the column headed "Wind — Distance" gives the distance traveled since the last observation ; after that date, however, the distances given are those traveled by the wind during the last 24 hours. The observations were made by Sergeant Meyer and the writer, and the following abstract of the record was recovered from the papers of the former, left on board of the vessel when the separation from the ice-floe-party^took place.

METEOROLOGICAL OBSERVATIONS AT NEWMAN'S BAY. The following meteorological record was kept daring our stay at Newman's Bay when on the boat-journey northward. The observations were mostly taken at intervals of four hours ; in some in- stances, however, more frequently. We chose Polaris Bay mean time in order to make the obser- vations taken at both stations more strictly comparable. The record kept by the writer extended originally over a longer period of time, but the only observations recovered are those given hereaf- ter. The barometer used is a Casella pocket-instrument that had been compared with the stand- ard at the Polaris Bay observatory previous to our leaving the vessel and after our return to win- ter quarters. The thermometer indicating the temperature of the air and the psychrometer were compared also, and in every instance the corrected readings entered in the register. The velocity of the wind was partly estimated, partly determined by means of one of Casella's current-meters. We think that our estimates are pretty reliable, as much experience had enabled us to estimate the velocity of the wind very closely. A number of experiments seemed to demonstrate that in no in- stance did the velocity as measured by an anemometer differ more than 4 per cent, from that based on estimation ; and, as the highest wind observed at Newman's Bay did not exceed twenty miles per hour, the error may be considered to be vei'y small. The quantity of ozone vras determined by means of Schoenbein's test-paper, which was kept exposed in a small wire-cage made for the pur- pose. The solar thermometer was a common thermometer as used to measure the temperature of the air, having its bulb and a part of its stem blackened with India ink. The instrument was ex- posed on cotton, resting on the sea-ice, as was the case with our instruments at Polaris Bay and at Polaris House. As the stand made for the thermometer fell overboard and was crushed by the ice, we were unable to fix the instrument otherwise than by laying it on a flat box, about six inches high, over the edge of which the stem of the thermometer projected about four inches. The latitude of our camp on the land floe was found to be 81° 55' 54" north, and the longitude 4-^ S"" 2P west. 2 M o 10 METEOROLOGICAL OBSERVATIONS a 1-^72. Jnne 14 15 16 17. 18 19 0^ •' h.

'J The preceding table shows that on five days the mean temperature as derived from four- liourly (or, as in one instance, from hourly) observations was higher at Newman's Bay thau at tlie other station ; the maximum difference equaling +?P. The five remaining days were colder, show- ing a maximum difference of —5°. 2. By taking the mean of the series on record, it will be found that from June 14 till June 23, inclusively, the temperature at Newman's Bay was by lo.22 lower than at Polaris Bay, the difference of latitude of the two stations being lO'.l. The greatest differ- ence observed at any hour occurred on June 14 at 1'' p. m., when the temperature at Newman's J>ay was 46°. 3, the record kept at the other more southern locality giving 38o.3 only. The following table exhibits the maxima and minima of temperature as observed at the two stations under consideration. At Newman's Bay, self-registering instruments were used but not at the other locality, from which we selected the highest temperature on record for each period of time during which we had not set the index of our self-registering thermometers.

The greatest difference between the maxima of the two stations occurred between June 13 and 14, equaling IS^.l, which seems to be rather abnormal. This considerable difference may perhaps be due to the fact that the thermometer at Polaris Bay was better protected against tbe direct rays of the sun thau the one at our more northern station. The instrument-shelter used there consisted of a wooden box about 18 inches long, 10 inches high, and 6 inches deep, which was fastened to a pole about 1.5 feet above Ihe ice. To pre\ ent the effect of solar radiation, the box was covered with tin-foil. In June, the maximum temperature of the day at Polaris Bay occurs at lO*" a. m., and it is scarcely possible that in an interval of one hour between two observations the change of temperature could have been as great as the difference between the maxima of the two stations. If the instruments at Newman's Bay were not as well protected as those at the other locality, tbe mini- ma, as observed at the former station, might reasonably be expected to be smaller than those of tbe latter, as the sun was circumpolar during the whole period. An examination of the values under consideration shows, however, that this was only the case in tliiee instances, namely, on June 15, 10, and 17, the greatest difference amoniiting to 5^.(5. P>etween June 13 and 14, when the greatest difference existed between the maxima of the two stations, the minimum as indicated by the self-registering thermometer at Newman's Bay was '2^.G lower than that of Polaiis Bay ; conse- quently, we might suppose thattlie temperatures observed at the former station were actually the true temperatures of the air in the shade, the more so as the index correction of our instruments was ascertained previous to our departure from and again after our return to the vessel. As men- tioned before, due allowance has been made for the same. Solar radiation. — Our observations on solar radiation made at Newman's Bay are not strictly comparable with those at the other station, as the bulb of the instrument used at the former local- ity was naked. It is to be regretted that we did not carry a black-bulb thermometer in vacuo, as tlie results obtained with the same would have furnished some valuable material for comparison with the observations on solar radiation made both at Polaris Bay and Polaris House. On account of want of room, we had to limit ourselves to the most necessary articles, and for this reason alone the more bulky instrument was left behind and preference given to a common thermometer. If we compare the readings of the naked black-bulb instruments at both stations, we shall find tliat in most instances the temperatures observed at Ne wmans Bay are higher than those at Polaris Bay. A rather abnormal difference was exhibited on June 19 at ll'' a. m., when the black bulb at Newman's Bay read 102°. 0, the temperature of the air being at the time 39°. C, which would give 02°. 3 of solar heat. At Polaris Bay, the amount of solar heat observed at the same time by means of an ordinary black-bulb thermometer and another thermometer suspended in the shade was only 2^.8. The result derived from the reading of the instrument in vacuo at the same place gives only 21°. 2 of solar heat, so that the difference between the observations made at the two stations appears to be ll'^.l in favor of Newman's Bay, although the instrument employed there was less perfect than the one made use of at the other locality. At the time of observation, the wind at Newman's Bay was from SE., its velocity being estimated at 10 miles, the suu shining bright, although the amount of clouds was J ; at Polaris Bay, it was blowing from W. with a velocity of miles, and the amount of clouds noted was f. "Whether the suu was obscured at Polaris Bay at the moment of observa- tion can not be ascertained. Winds. — As we stated on one of the preceding pages, the winds in Smith Sound and Kobeson Strait are rather local, and a comparison of the limited number of observations relating to this subject will corroborate this view. On June 14, the prevailing wind at Newman's Bay was NW.; at PolarisBay,it was either calm or there was a slight breeze from SE. June 15, wind at Newman's Bay NW., except at 11'' p. m., when it was calm ; at Polaris Bay, calms prevailed till l'' p. m.; after that time light breezes from W., SW., NE., and NW., the lat- ter prevailing. June 16, wind at Newman's Bay veering from W. through SW. to S.; calm during the last two observations ; at Polaris Bay, NE. prevailing. 14 METEOEOLOGICAL OBSERVATIONS AT NEWMAN'S BAY.

The following meteorological record, containing the direction of the wind and tbc temi)era- tiire of the air, was kept by Sergeant F. Meyer during the drift of the ice-floe-party. It was tirst published in the Annual Report of the Chief Signal-OfBcer to the Secretary of War for the year 1873, whence we have taken it. As might be exjjected, the record is very scanty, resulting from insufficiency of means and the sufferings of the crew during the eventful drift. 16 METEOROLOGICAL OBSERVATIONS a 1-1 P 'So a o (-1 a o s £ OJ a H cs 1-1 'to h-1 ' a 5 9^ H P 1-1 6 -^ .^ 'to q 1-1 Direction of wind. 1. u 1 1872.

The following meteorological record was kept by the writer daring the boat-journey from Polaris Llouse to Melville I!ay. Oircamstances did uot permit the taking of observations at regular iatervals, but they werj made whanever this could be done without inconvenience, both when oa shore and afloat, or when we encamped or were otiierwise detained on the land-floe of Melville Bay. 20 ]METEOROLOarCAL OBSERVATrONS Psycliroiii- ctci'. i.-r;;.

Tlic UK'tc'(iioloi;ical (ibseivations recorded hereafter were made on board the whaliiii;- steamer Arctic, on wliicli a jiortion of the boat-party had been received. Oapt. William Adaius kindly shared Lis catiin with us, and afforded ns all the facilities for making;' observations one could ask on board of a vessel. ^Vith bis permission, the ship's cari)enter niade us a box similar to the one we had used on board the Polaris, which was placed on the quarter-deck to receive the instruments; the latter being set up a few liours after we had been transferred on board. The instruments used were the same we had made our observations with during our retreat from Polaris House. On July 9, the \esscl being moored to an icefloe, we had a good oppoi- tuuity to compare the aneroid, from which the following barometric results are derived, with Green's standard. At ii'' p. in.. Green read .30'". 220, temperature of mercury GO-. 2 F., giving .';(1"'.141 when reduced to 32'^ P., and 30'".191 when corrected for index-error. Casclla. read o(l'".210, its'correction being consequently — 0'"-.010, which was duly applied to the instrumental readings. Owing to the kindness of Commander A. H. Markhara, It. K, who was a passenger on board the Arctic, we were enabled to make the observations bi-hourly; this gentleman usually standing on watch from C' p. m. till midnight, during which tinre we turned in. In regard to the o'xservations, no further explanation will be needed; we merely limit ourselves to file statement that the velocity of the wind is not based on actual measurement, but is only esti- mated, with the exception of the first week, during which we used a small anemometric machine we had constructed with the wheels of an old clock, but whicli was broken soon afterward by au accidcut. 24 METEOEOLOGIGxiL OBSERVATIONS Latitude, 7o .O^'' N. ; longitude, 7") .2.")'

I'nfortnnately, however, the observa- tions made on board of these vessels were not found lit to be used, as we were utterly unable to determine the index-eorreetious to be applied to the barometers, thermometers, or psyelndnieters, although we had the instruments sent to this city through the kindness of the Department. AVheii they arrived, the barometer was found to be limkeu, and, as there was quite a uund.ter of thermome- ters contained in the box, we had no means of asciTtaiiiing which instruments had lici'ii used in making the observations. There could be no doubt in regard to tlie identity of the psyeliroiiieter, as there was only one sent; but, as tlie eonstructiou of this instrument was such that the wet-bulb (which was surrounded by a considerable quantity t>f oakum in a somewhat filthy condition, instead of a piece of muslin, as commonly nsed) had to be entirely immersed when the instrument was being used, \\e had some seiious donbts in regrdd lo the coirecincss of the obscr\ aliens, the mne so as an examination of the record demonstrated that there was a ccrtaiu psychrometric dif ference prevailing which hardly varied during a day. J5esides th's calannty, the readings were not taken to the tenths of a degree, but gave the full degrees merely, which, as may well be imagined, is not sufllciently accurate at low temperatures. Ibegarding the nonu'iiclature of the clouds, there seems to have been some uiisunderstauding, as there is hardly one day without the mention of nimbus, which, as is well known, seldom occur in the Arctic regions; oi-, at least, in the latitudes where they are recorded in this case. The fads stated above may be of sufficient weight to excuse our not giving these observations, as they would, perhaps, only mislead. In giving ;i brief reca[)itidation and discussion of the preceding observations we shall begin with the TKIirraiATTKE. The following table contains the daily mean temperatures as observed during .Inly and August, IST.j; also, the daily maxima and minima, next to wliich the daily ran ge will be found: Olltll.

The mean temperature of July, in 1850, for the mean latitude, Ti-^A N., mean longitude, 5S'^.rj W., according to the meteorological register kept l)y the first Grinnell expedition, was 35o.9; and that of August, in the same year, oi^.S, mean latitude, 75^.3 X., mean longitude, G2'.0 \Y. ; hence the dif- ference between the two mouths is l^.l, varying but slightly from that between July and August, 1873, although the season was more open during the latter year than in 1S~>0. The following table gives the mean temperature of July and August for different stations of Arctic America : Loriility. Yuar.

The maximum temperature in July was obserxed by us at 10'' a. m. on tlie lUtJi, lieing r»7''.5 ; the minimum, during the same mouth, of 'JtP.'i, occurred at 8'' a. m. on the 11th, during snow-fall. In August, the maximum oeeurred on the 2d, at (>'' p. m. 11''-. .J, and the minimum, namelj', 29^.3, ou the 21th, at 0'' a. m. As the vessel was under way during the greatest part of the time, changing her position sometimes considerably during one day, being at one time in clear water and tlieu forcing her way through ice, it can well be imagined that the daily range of temperature will have suffered gieater modifications than if the sliip had lu'e.n stationary. The greatest range iu July, amounting to Ki-.O, was found on tlie 20th, one day after the maximum temperature of this mouth had been observed; the smallest range, of fo.O, occurred three days later. In August, we find the greatest range on the 10th, namely, llo.3; and the smallest, of 1°.0, on the 2Sth. The warmest day iu July had a mean temperature of .jO-.'.lJ and the coldest of 28-'. 22, its range being consequently 12 -.71. The highest mean temperatuie in August occurred on the 2d, namely, 40'. ."i3 ; and the lowest, of 31°. 00, On the last day of the mouth. i M o 50 .^1 ETEOIJOLOGICAL OBSERVATIONS ATMOSPnERIC PEE,S,SLRE.

For the mean positions in Baffin's Bay, men- tioned abave, the log of the first Grinnell expedition gives the values: 29''".82 for July and 29'''.i)8 for August. From the obssrvations of Sir Edward Belcher, taken, in 1853, in Northumberland Sound and Wellington Channel, we obtain for the mean barometric pressure, in July, 29'".670, aud in Augu.st, 29"'.719. In both instances the barometric column was higher in the latter month than in the former. The same was the case at Port Kennedy, in 1859, aud at Polaris Bay, in 1872, but not in Baffin's Bay, in 1857, when the mean pressure during July was, by 0*°.017, higher than in August. This was also the ca,se at Van Kensselaer Harbor, in 1854, and at Port Foulke, in 1861. Evidently, we might expect the mean of the former month to be higher than that of the latter, at all the stations above mentioned, if the series of ob.scivatious were sufficiently long and numerous. It should, however, be borne in mind that the atmospheric pressure must be considerably affected by the condition of the ice in the seas surrounding the respective stations. KECAPITULATIOX. 51 WINDS.

In July the prevailing wind was due north, while in August it blew from the opposite direc- tion, although we had decreased both our latitude and longitude, and were consequently approacli- iiig Iceland. A glance at the table containing the mean atniosiiheric pressure shows that the latter was in strict accordance with the prevailing direction of the wind, viz, higher in July than in August. In both months the percentage of calms follows next to that of the prevailing wind, the calms beiug, however, more frequent during the former month than during the latter. If we coui- pare Sir Edward Belcher's (.)hser\-ati()iis, previously referred to, we shall see that, in July, 1852, tbe vessel cruising in Baffin's and Melville Bays, the prevailing winds were southerly; and although a portion of the following month was spent in Northumberland Sound, where southerly winds are largely prevailing, northerly winds were noted more frequently than those froai the opposite point of the compass. Tlie first Grinnell expedition, in l.S.'iO, mostly met with northerly wiuds during the two months under cousideration, southerly winds prevailing only during the first part of July. We abstain from drawing any more comparisons, as our series of observations are too short and the winds too variable to enable us to deduce any reliable results from them; besides this, we should have to disregard the velocities, which are given rather vaguely in the difl'ereut documents that might be taken iuto consideration. From the detailed record it will be seen that we never experienced any storms, although, in several instances, the sea was very rough and ugly; and as on such occasions we always noticed sudden changes of the barometric column, we might conclude that high winds must have been raging in the vicinity. 52 M ETEOROLOGICAL OBSEIJ VATIONS lIVfiUOMETRICAL OBSERVATIONS.

It will be remembered that the barometric mean of July was, by 0"\217, higher than in the foUowiug mouth ; but a comparison of the mean atmospheric pressure and the mean force of vapor would show that only a small amount of the higher pressure during July is due to the influence of the force of %apor, wliieh would only affect the second decimal in our barometric mean, if the corresponding correction was apiilied. The sudden increase of the force of vapor in September will readily 1ie understood if we keep in mind that the greater portion of the seventeen days in this mouth, during which the observations were made, were spent on our journey homeward through the ^"orth Atlantic. As in the preceding record of meteorological observat:ions those on atmospheric precipitation are not given iu detail, we proiiose to do this here in the following synopsis: July 11.— Light snow during 1 hours; amount not measurable.

If we calculate the mean amount of clouds, we obtain for July, 2.2, and for August, 2.s. Consequently, it was clearer in July than in August; during the latter mouth there is not a single instance on record when the sky was perfectly clear. At Polaris Bay, August was clearer than July; the mean amount of clouds for the hitter month being 2.7 and for the former 1.9. Fog occurred, however, more frequently in Lancaster Bound and BafQu's Bay during July than dur- ing August, as may be seen from the following table, in which we have grouped the number of re- corded fogs according to the direction of the wind observed at the tiiue: In July fog was observed on G3 occasions, and in August on 42 only, although the record for the latter month is more complete than for tho former.

SOLAR RADIATION. The following observatioas on solar radiation, which formed a part of our meteorological record kept on board the Arctic, were not given on the preceding pages, because we did not consider them sufficiently accurate for publication; but as they may still be of some interest, we do not hesitate to record a portion of them in this place. They are faulty in that they were not made with a ther- mometer in vacuo, it being at the time beyond our means to obtain one. The instrument used was a long-stem Casella standard thermometer, the bulb of which was blackened with Indian ink. la order to make the observations somewhat comparable with others, we inclosed the bulb and a por- tion of the stem of the instrument in a test-tube, filled with air. As in our previous observations, the thermometer was exposed on white cotton. The following table contains the observations made from the 18th to the 22d of July. Next to the columns containing the readings of the black bulb the temperature of the air is given, fol- lowed by the amount of solar heat. The last column of each division shows the amount of clouds, as explained before : July 18, 1873. July 19, 1873. July 20, 1873. July 21, 1 1873. Lat.,73°.15'.18"N.;lonff., Lat., 73'-\51' N.; loG S-.

CnROXOMETEll-JOUIlXAL. As iTi the course of the astronomical ami peiidulum observations wc sliall frequeutly liave to refer to tbe rates of the clironoaieter-^, we give lierewitli tliat part of our chronometer-journal which was saved from tlie wreelc. The expedition was supplied witli ten chronometers, four of which were pocket-chronometers. Three of the six box-chronometers (Neg'irs) indicated mean, the rest sidereal time. The three mean-time clironometers were sent on board of the Polaris previous to the sailing of tlie vessel from Washington <-'ity, wh('r(»as the three sidereal ones were procured from the luaker at 2iew York. All tlie instruments were kept in a little closet at the port side ol' the v.ih'wi until we left New York. Tlien tlie box-chronometers were transferred in two cases (three in eacli), resting on four legs each, and fastened to the eabin-tloor near the mast, but disctmnected from tlie latter. The accompanying diagram is intended to show the position of the boxes, which were lined with heavy cushions of horse-hair and cloth, in order to protect the instrn- meuts against injury from con- cussions of the vessel with ice. As will be .-een, thechronometers kept their respecti\e rates better than could have been expected ; and we think that, besides the superior cliaracter of the instru- ments, this uniform rate is in great pari:, due to the manner of keeping the time-pieces, as tlie lining of the cases uot onlyi)re- vented or moderated the shocks produced by running against ice, but also ke[)t the variation of the temperature in the box within a small range, as proved by a ma\i mum and minimum thermome- ter, kept occasionally for some time in one or the other of the boxes during the winter of 1S7I to I.STl', spent at I'olaris Bay. Tlie iustruiiieiits were compared ami wound up daily at the same" time, until the arrival of the vessel at Goodhavn, in AVest Greenland; this was done by tlo^ late commander of the expedition and by the writer. Afterward, the comparisons were made mostly by Mr. R. \Y. Cryan and the writer, or by :\lr. Fred. Meyer. In s.mie rare instances, others assisted. The comparisons were made to the nearest tenth of a second, and in such a manner that one observed the instrument selected as standard, and gave his signal by calling "time," when the other called off the seconds, minutes, and hour, as indicated liy the respective chronometer he compared. Invariably, at least two comparisons were taken of each time-piece and the standard chronometer; sometimes, if the results did not agree within 0^l!, a third or fourth one was obtained. Finally, it may be well to state that, in the following record, the box-chronometers are not designated by their numbers as given by the maker, but by the letters A, B, O, D, p], and Z (standard). This was done partly to prevent mistakes in recoiding a long row of figures ; partly because it is rather disagreeable to write more than is necessary when the temperature is low. The pocket chronometers (by different makers) were designated F, G, H, and I. After the loss of the vessel, the three remaining box-chruuometers were kept in Polaris House on the writer's desk. I.

INTRODUCTORY. Unfortunately, tlie greater and more valuable portioa of the astronomical record was lost during tbe separation of the vessel from the ice-floe-party; thougli a very few sights for the determi. nations of positions on shore preceding the time of the disaster were recovered afterward from loose sheets of paper on which their computations had been made. The observations, mostly taken by Mr^ Bryan, were very numerous, and positions were determined astronomically whenever practicable. Tlie observations taken at winter-quarters alone consisted of about three hundred lunar distances, a number of moon-culminations, a great number of transits of stars, a number of occultations of stars, and a great number of altitudes of the sun on or near the prime vertical for longitude and time. For the determination of the latitude of the place, there were on record a great number of circum- meridian altitudes of the sun and a number of altitudes of stars. Tbe iustrumeut.s used in the above-named observations were a Wiirderaann transit, tbe de- scription of which we are unable to give ; Gambey sextants, divided to 10" ; and artificial mercury- horizons. The chronometers used have been referred to in a previous chapter. A sail the observations were made in high latitudes, where the celestial bodies hardly change their altitudes one-fifth of the amount they do here in the same interval of time, it might be considered sufficient, in making observations for latitude, to I'ead the time to the nearest second, and to retain the nearest tenth of a minute in the computation. In regard to observations for time, the nearest balf-second or one-hundredth of a minute would be sufficiently accurate, and, in reading off the arc of the sextant to the nearest tenth of a minute, a very satisfactory result would be obtained. Although the observations recorded hereafter were made in the usual way, we still deemed it proper to modify them according to the view expressed above, in order to simplify the process of their computation. The original observatious, as recorded at the time they were made, are deposited in the archives of the Smithsonian Institution, and are accessible to any one that may wish to examine them in detail. In making the reductions, Bessel's Tables of Refraction have been used, after having been modified and extended to adapt them to the conditions of the regions where the observations were made. The following table is modified accordingly for a mean atmospheric pressure of 29.5 inches, and a temperature of ip Fahrenheit, having as argument the double altitude. 2A + i 2r 2^ 2r 2 A 2f 2 A 2r O 1 / o / / o ' 7 v)s_ 2 11 19. 9 24 9.8 50 4.5 20 27. :.! 12 in. 5 26 9.0 55 4.1 40 26.5 i:i 17.3 2S 8.4 60 3.7 8 25. 7 14 16.2 30 7,8 65 3.3 '20 24.9 15 15. 2- 32 7. ■> 70 3.0 40 24.2 IG 14.3 34 6.9 80 2.5 9 23. 5 17 13.6 36 6.5 90 2.1 20 22. y IH 12.9 3,8 6.1 100 1.8 40 22 2 19 12.2 40 5.8 110 1.5 10 21.

As the sun or any heavenly body, when on or near the prime vertical, moves nearly uniforiuly, we are justified in combining sets of observations talien on or near the prime vrrtical into groups; taking tlie means and reducing each observation to tbat epoch by making use of the well-known relation that the variations of the altitude are equal to the variations of the time multiplied by tbe cosine of the latitude, viz : — J h = J 1. 5r^ or, as our variations are referred to the double altitudes, and J t in time, we get the formula — J h = 30 J t >f^ Adding then the corrections necessary for index-error, refraction, parallax, and semi-diameter, we obtain the single results of the observed double altitudes at the epoch.

Tlie st(;el knife-edges are li.2 inches from the ends of the bar, 3 inches long, O.'.i inch liiglj, and (M.'7 inch wide at the base; their section is triangalar.

They are scirwed to a br.iss plate, and sup[iorti_'d by a hea\'y block of wood, which is fastened to the case in which the pendulum swings. There is no adjustmiiit lor horizontality (jf the supiiorting steel plates other than what is given by the ^■ertical posiiion of the case. The arc of vibration is read off on a scale at the bottom of the case, which has a glass door in front, pei'uiitting a view of the whole pendulum. Twot ther- niometers are permanently fastened inside the box ; one just above the support, tbe other on a le\el with the swinging knife-edge." As the description of the observatory at Polaris Bay has already been given, we limit oursehes here merely to stating how the pendulum was mounted. In order to disconnect the instrument as far as possible from the small hut in which it was swung, a sipiare hole was cut through the floor of the latter, in the middle of the western wall of the observatory. Underneath this opening a heavy piece of timber was frozen solid to the grouiul. As the floor of the building did not rest directly on the soil, but was placed on bi'ains of oak, the plank, mentioned before, was eul irely isolated from the obscrvator\-, and bcramc as firm under the inflnencc ot ' I'liy.-it.'il I llj.sn valiuiis ill llie Aivtic Seas.

On this piece of timber the peiiilnluin-box was screwed in such a manner thai the plane iu which the peu- duhim was to be swim- was exactly in that of the meridian, so tliat the utmost steadiness would he secured. I placed a strong barrel outside the observatory on the same plank ou which the pendulum box rested. The barrel was surrounded by a heap of gravel, which was moistened with sea-water iu order to cement it in a solid manner to the plank. After this was done, we cut a liol(> through the western wall of the observatory, exactly behind the place where tlie pendulum-box was fastened. A half-iucli irou bar, bent at right angle, was passed through this hole, and one end of it was fastened to the back wall of the box by means of five screws. The other end, (see diagram,) which was about .'3 feet above the center of the barrel, was screwed to a ,j-inch iron bar, Mhich was set up nearly pei-peudicular in the keg. After having accomplisbed the work so far, the barrel was filled with gravel and sand, over which we poured some water. Eefore the mass was frozen hard, I leveled the pendulum-box as nearly as could be done ; and when it was found to be tolerably level, the bar outside was fastened by means of ropes to the wall of the observatory, in order to prevent it from giving way and from disturbing the position of the box. After two days had elapsed, the gravel was f.ozen very solid, and the ropes were removed. It was found that the box had not changed its level, but at the same time I saw that it was not quite as steady as I had anticipated. To secure it better, a hole of 3 inches diameter was drilled through the tloor of the observatory 1 foot north of the box, and another one of the same diameter, and at the same distance south of it. Through eacli of these holes an iron bar, 1 inch thick and 3 feet long, was driven into the frozen soil, and connected with the box by means of two other iron bars bent at right angles, similar to AT rOLARIS BAY. tbe one mentionea above, and screwed together in a similar mauuer, as shofl u in the accompanying- small diagram. In this way sufficient stability was obtained. In order to tell tlie steadiuess of the box, I placed a glass dish fdled with ether on the solid block of wood supporting the kuife-edges of the pendulum, and placed some semen ly<'op(xlii on the surface of the fluid. After this was done I ordered the blacksmith to strike with a heavy sledgehammer upon the lloor of the observa- tory, and found that uo vibration was communicated to the liquid. Tlicieartrr I cuald be satisfied that the box rested on a firm base. Let us now describe how the experiments of vibration were conducted. The series of observa- tions taken at Polaris Bay, which we propose to give here (irst, was l)egnn -January 5, 1872. One set was always taken in the morning by Mr. Meyer (telescope) and the writer, (chronometer,) and another one in the afternoon by ]\lr. Bryan (telescope) and the writer. The following sclieme was adopted for observing : A. ^r. ]■. M, First day, swinging face 1 and .j Second day, swinging face 2 and 4 Third day, swinging face 4 and 2 Tonrth day, swinging face ^^ and 1 Fifth day, swinging face ;; and 1 Etc , -land 2 According to Mr. Schott's suggestion, the nine series of observations, making one set, were taken at intervals of 1."; minutes or at multiples of 15 minutes.

Tbe telesco])e was screwed to the transit-stand, the legs of which rested on the soil, to which they were frozen. The point of the swinging knife edge served as a mark, and observations were made with vibration from right (E) to left, (L,) (north to south,) and from left to right, in order to correct for * 111 two instances wi^ nliservi'il till T.

An arc ol' a cirelo, of o'.M'.j iuclics radius, divided from the middle, each way, to 0'', witli subdivisions of tentlis of degrees, was placed o\ cr the swinging knife-edge, and the extreme excursions to the right and left were noted. The limes are recorded by sidereal chronometer A, which was compared with five box-chronometers by means of a iioeket chronometer before and aftcH' each set of observations was taken. The vertical thread of the telescope was pointed to the zero of tlie scale, which itself is placed over the knife-edge when at rest. The pendulum was swung in four dilferent positions, designated by the number stamped on the rod near each knife edge. Tlie number facing the telesi'ojH' and swinging thus indicates the position. The nunibers 1 and 2 arc on one side, and 3 and i on the reverse. The steel plates upon which the knife-edges rested were le\eled by a small spirit-level e\(Ty time before, the set was begun, when tlie door of the box v. as closed, and kept shut till the set of nine series was linished. The same jiosition of the knife-edge on the steel plate was setmred by means of a tine liiu' marked vertically on the side of tlie plate. The knife-edge was made to rest just aliovc tliis line, and its miijdle positi(.)n, willi resj)ect to tlic opening left for tlie body of the rod, was seemed by :i l>rass fort stuck o\er the roil until it rested against the back of the box. Tlie fork Avas always removed before the pcndnlnm was swung, and evia-y precaution was laken to keep the kiiile edges sharp and clean. The elcA'ation of the lower knife edge above the h;df-tide level was found to be ■ji'<.~> feet. The geological formation of Polaris Bay and its whole vicinity is upper Silurian limestone, covered by drift, partly of the same material. It was not supposed that the limestone could contain any large cavities which might influence the vibrations of the pendulum. Before giving the record of vibrations we propose to insert the comparisons of the chronoinc ters. Unfortunately the corresponding observations for time ar(5 lost, but in the record of the tidal obsei\'ations we found some rati'S of chronnmeter Z, (standard,) as dedaced at the time.

It is believed that the above chronometer errors and rate ■; cm Ic, relied upon. A glance at our chronometer journal from later dates — 'the portion that was saved — beginning Septembor2l, 1872, will show how very uniformly the tiine-]iieee5 kept tlieir respective rates, which agree sub- stantially with those given above. .Vs has lieen mentioned before, the chronometer (sidereal chro- nometer Aj which was used to record tin.' times of transits was c(impared l.icfore and after each set of experiments with hve box-chronometers by meaiss of a pocket-chronometer, (F.)

TEMPEEATUEE OF THE PENDULUM. To obtaiQ the true temperature of the pendulum at the time of obserration, two thermometers were fastened inside the box: one just above the support; the other (nearly) on a level with the swinging knife-edge. As the temperature of our little observatory, which was heated by means of a stove, was always influenced by that outdoors and by the velocity of the wind, which durino- the time the observations were carried on, amounted sometimes to forty-six miles an hour or more it was found that the temperatures indicated by the upper and the lower thermometer nearlv always showed differences from 10"^ to 15^ F. Of course, the higher temperature was always indicated In- the upper thermometer, which was surrounded by a stratum of air warmer than that influenciu" .the thermometer below. This circumstance caused great inconvenience in the reduction. The conductiug-power of brass being different from that of the air, we might have assumed, aptiori, that the temperature of the pendulum was not the same as that indicated by the thermometers at the time of observa- tion. According to the difference in tlie conductingpower of the two mediums, we might infer that whenever the temperature of the air was rising that of the pendulum itself would be lower, and when it was falling the actual temperature of the pendulum must have been higher than that indicated by the thermometer. Though many attempts were made to keep the temperature of the observatory uniform, they were unsuccessful: the upper and the lower thermometer always varied. At our second winter-quar- ters, at Polaris House, where also numerous exjieriments were made, I tried to eliminate this source of annoyance by attaching another thermometer inside the box, halfway between the two instruments mentioned before. Although we pi'opose to discuss the observations taken during our second winter-rpiarters after those made at Polaris Bay, we still think that we are jnstifted in taking here some points into consideration that have special connection with our case of temperature.* The third thermometer was used during the observations made at Polaris House. Calling the upper thermometer E,, the middle E_., andthe lower E3, we found that the temperatures as indi- cated by El and Ej differed but slightly, the difference amounting on the average to 1° F. only after the instruments had been corrected for their errors of graduation; consequently, the main difference of temperature must exist between E3 and E3, in which interval the two strata of extreme temperature seem to meet. In the reduction, we assumed that the two strata met half- way between E2 and E;,. In order to get a more definite idea of the relation of the variation of the temperature of the pendulum to that of the air surrounding the latter, we made the following experiments: A brass pendulum, of nearly the same dimensions as that used by us in the Arctic regions, was made at the United States navy-yard under the supervision of the writer. As it was a point of the highest importance to get the actual temperature of the pendulum itself, three holes were drilled into the rod: the first one was 22.2 inches from the top of the pendulum; the second, 24 inches from the first; and the third, 20 inches below the second. The bulb of a thermometer was introduced into each of these holes; and each thermometer was held in position by means of a cork, through the center of which the tube passed. To make the contact as perfect as possible between the bulbs of the instruments and the brass rod, the cavity was filled with brass filings. * We intended to repeat tlie experiments at Polaris Bay during the summer of 1872, but were prevented from doing 80 by the perilous position of the ship. .1 Q PENDFUJM-EXPERIJrEXTS TLe peudaliim was mounted in the same way as tlie one used during' our former observations. Three thermometers were attached inside the box in the same manner as mentioned above. The bulbs of these instruments, intended to indicate the temperature of the air, were at the same levels with the bulbs of those fastened to the pendulum. Tiie observations were made at the Smithso- nian Institution, on the third tloor of the north tower, in the west room, which has three windows reaching down to the floor; two of the windows facing north and one west. The room was heated by means oi' an iron stove, and the pendulum-box was about the same distance from the stove as the instrument at the rolaris Bay obser\atory. In order to obtain extremes of temperature simi- lar to those at northern stations, the experiments were carried on during the cold weather of Feb- ruary last (187.")^. A large fire was lit in the sto\ c, and the cold air from outdoors was made to rush in through an opening at the window if required; the opening being '2'> inches wide, !■"> high, beginning '2 inches above the floor of the room. The thermometers attached to the pendulum are desiguated — Pa (uppermost); P,, (middle); Pc (lower): the corresponding ones, to indicate the temperature of the air iu the box — E,, E,.

We found the differences of the temperatures of the pendulum and tlie air to be — 30.2, '.7, and l-'.7; ' or, on the average, the pendulum w:is found to be 10.9 colder than the air surrounding it; but in our reductions no use was n)ade of these latter values, as they were not considered to be relia- ble enougli, and the time at our disposal did uot permit us to make auy more experiments. As we stated above, an additional thermometer (P,) was inserted between P,, and P,, during the experiments made on February IS and 19; and, by expressing the temperature of the different poiuts of the pendulum where the thermometers were attached by the following equation: For the determination of the coefficients /„, «, l>, and c, we have the observed temperatures of four points of the pendulum at different distances (y), which furnish the equation of conditions; further, the last two sets of observations furnish the three following equations: + 50.2 = + 12a + 144& + 1728c a = + 0,7G - 30.4 = - 5« + 25& - 125o h = + 0.004 - 40.7 = - 10« + 100& - 1000c c ^- 0.002G AT POLAEIS BAY. ^^ hence, the temperatures of the pendnlum, and their variations iu regard to y aud the point of max- imum variation, may be expressed by the following three oijuations: t = 01O.3 + 0.3S(/ + 0.01//- - 0M03y' ^ar- = -^-= 0.3S +0.002;/ -0.0009/ !,y.= 0.002 -0.001C// = // = lind.. + 4.9 = +12,7 + lUb + 172Sc „ = + o.i;.:^, --•'' = —■"''+ 2:./)— i2:)c ?< = + 0.0070 = -lOa + 1005 - 100c : c> = - 0.0021 ■ O..I f= 60O.4 +0.31)/ + 0.(102,/- - 0.0003r di y- = var. = + 0.31 +0.004;/ -0.0009,/- (Vi J-. = + 0.004 - O.OOIS]/ = lience, y = +2 inches, which indicates that the cold and warm strata of air meet two inches above the place occupied by 1\,. Before one inch was found for ,/. which shows that the condi- tions remained about the same during the last two days. 3IETH0D OF EEDrCTION. As the different sets of transits were taken at intervals of fifteen minutes, or at multiples of fifteen minutes (with but very few exceptions), the times of transits are represented by the series given iu the first column, headed "15'" interval."' The second column gives the approximate chronometer-time for the mean of the series, cor- responding to the mean of the time of EL, EL. The third column contains the arc of vibration, as interpolated for the middle, between the time preceding and following, and is written between. The two colirmns next following give the respective temperatures of the air, interpolated from those observed, corresponding to the same time as the arc of the precediu.;- column. The figures at the bottom of these two columns are the mean temperatures of the air during the time of obser- vation. As we may presume that the mean temperature of the air during the entire time of observation is equal or nearly equal (differing but by a constant), we may presume that the tem- perature of the pendulum can be deduced from the observed temperature of the air by using the ratios found, as explained above. This was done iu such a manner that, first, the differences were taken between the observed temperatures and the mean (given below); then, these differences were multiplied either by i (for P„) or by J (for P^), and the results added to the respective means.* The column headed '-I.TIA'" gives the correction corresponding to the arc Ai for the interval of time of fifteen minutes. We assumed that the arc at the middle would correspond to the mean of all the arcs, even if the interval was divided into an infinite number of parts, and then the mean of all the arcs taken. The correction for arc is obtained in the manner followiug: The time of vibration observed is nearly — .Vi.(.^..^^....) * At Polaris House, by J for Pb- 42 rENDULUM-EXPEEIMENTS and, if tlie observations continue for a very short interval of time, the observed time of vibration has only to be divided by — 1 + A' sin^io IG or the number of vibrations performed in any interval of time, say fifteen minutes, as in our case, or 900 vibrations (more or less), has to be multiplied by the above quantity. Therefore, the correction to an infinitely small arc becomes, in our case, with sufQcient accuracy, sin^ 1° 900 A^ 10 giving, after the calculation has been performed, 1.71A2 the unit being 0.01 of a vibration.

As in former reductions of ob.sor\ atioiis made with the Hayes pendulum, t 50° F. was adopted as a convenient standard temperature, we used the same value, which was thrown off in making the respective additions. The results are given opposite the horizontal lines in the next column to the right, headed -Pa and - P,,, which have to be multiplied by the two co-efficients of temperature, 0.3.35 and 0.135.^ * The few extreme cases beyoud the limit of this table can easily be supplied. t Schott (luc.cit., p. 33) assumed the coefficient of expansion to be 0.0001045, and the coefficient for the number of vibrations, 0.4518. Instead of the latter v.alue, we used 0.452, which was considered to be accurate enough. t To take not only the expansion, but also the unequal deu.sity of the pendulum into account, we assumed that the two strata of cold and warm air met midway between E^ and E., (as shown above). In order to obtain the factors men- tioned, the moment of inertia of the pendulum (of the dimensions as stated above) was divided by the statical moment, which gave the length of the simple pendulum. Designating by ti and r^ the number of degrees Fahrenheit aljove 50° of the upper and lower end respectively, it was found that the correction to be applied to the usual correction for tem- perature, 0.452 l-~ — j on account of unequal density, is, + 0.10(7,--,) + 0.17(n-r,) if the two strata of air meet at Ve or Pc respectively. AT POLAEIS BAY. 43 The last column contains the sum of the above-named corrections, which have to be applied to the mean of EL, EL transits, in connection with a small correction, i (to be found below), in case the interval of time during which a series of transits was observed was not fifteen minutes exactly. At Polaris Bay, we made this small correction by assuming the excess for one minute, derived from a preliminary reduction, to be —0^06, whereas at Polaris House the value of -|-0M0 was made use of. In recapitulating the transits, only the tenths and hundredths are given, as the whole num- bers are not necessary, because the differences only are needed, and the whole seconds are easily supplied hereafter. In taking the mean of the following series of transits — 39.52 = 39 + 0.52 30.50 = 30-1- 0.50 21.52 = 21 -f 0.52 12.60 = 12 -H 0.60 M = 26.03 = 25.5 -|- 0.53 we see that the mean of the fractions differs but 0^5 from the actual mean if the whole numbers are carried along. For this reason, only the mean of the fractions was taken into account. The sign of the correction r (the total reduction for arc, temperature, and barometer) is the same for the upper series and reversed for the lower. By adding i and r to the mean, we obtain the corrected transits, corresponding to the vertical argument (I). The observations taken at Polaris Bay show that the pendulum was losing on the chronome- ter, or the chronometer gaining on the pendulum: the excess of the pendulum was negative, whereas at Polaris House it was found to be positive. In order to obtain the numbers in the col- umn headed "Interval" (of the upper series) the preceding transits had to be subtracted from the middle series, and the middle series from the transits following. The necessary whole number of seconds was sujiplied, because there is only an even number of vibrations between the series.* The sign -|- was attached to the preceding, and — to the following interval, in order to make the excess appear negative. Underneath the column under consideration, the sum of the negative and positive intervals is to be found. These sums ought to balance each other in case the transits of the middle series were perfectly correct and the errors of the other transits would balance each other, as they gen. erally would do according to the rules of probability. Consequently, the difference of these sums is equal to the product of the error of the middle series into the number of series. The column headed "Observed" gives the observed intervals as deduced from the mean of all the series, and not from the middle series alone. The column headed "Product" gives the product of the interval and the excess, as required, according to the method of least squares. The sum of the products is given below the column. No correction is needed if the two strata meet .at Pb. We adopted tbe coefficient 0.10; and tlie coniijlete correction for tlie sum of vibrations performed in a solar day becomes, after combining tbe coefficients of ti and -; into one— 0.322 T, +0.130 Til for a solar day, and, therefore, for an interval of 15 minutes — 0.335 ri + 0.135 72 the unit being now 0.01 vibrations. " As the excess was positive at Polaris House,, the middle had to be subtracted from the preceding transit, and the following transit from the middle. Instead of finding the excess at once, it might bo found to be more convenient to assume an excefe by first approximation, in order not to be compelled to carry over so many figures and find only the correction to this assumed value; bat, as the excess for 15'" was under 1» at Polaris Bay, the excess was found at once. At Polaris House, it would bo well to assume 1^5, and find the correction to this value. 44 PEND ULUM-EXPEEIMENTS aud should be divided by the sum of the squares of the intervals (^P), which gives the excess for 15™ chronometer-time, aud, if multiplied liy 96, gives the excess (retardation) for 24'' chronometer- time. As the chrouometcv A was gaining 23SM in a solar day, the number of vibrations of the pendulum performed during a solar day will be equal to 86400 + 238".! = retardation. The column before the last contains the intervals, and the last one (J) the residuals, expressed in hundredths of seconds of time. In comparing the residuals of the different days with each other, we perceive a regular wave, that can be traced through the whole series of observations. We can account for this only in the following manner: As has been stated before, the temperature, as indicated by the upper thermometer, fastened inside the pendulum-box, was always found to be higher than that of the lower thermometer. As the pendulum was always re\ersed a short time before each set of observations was taken, except on January 5, a. m., and on January 8, a. m., the cold end of the rod was turned upward and the warmer one downward. It is easy to perceive that the upper (now colder) end took up the tem- perature of the air, as indicated by the thermometer, but slowly; whereas the lower (now warmer) end radiated its heat more readily. When the difference of the negative and positive sums of intervals (as stated before) was larger (except during the two days mentioned above) than could be attributed to the effect of the error of observation of the middle series, it was assumed that cooling had taken place after the pendulum had been reversed. To simplify the process of this special reduction, the action of cooling was assumed to commence at the moment the pendulum was reversed, aud to be uniform, although it is more rapid at the beginning than at the end. To obtain the rate of cooling, it was necessary to divide the difference mentioned by — 400 in the series of 4 hours, and by — 1080 in the series of 6 hours. The following scheme will show how this cau be done. Giving, in the first column, the inter- val ; in the second, the cooling, that for the interval of 15 minutes taken as unit; aud, in the third, the correction for cooling, the correction being represented by the squares of the second coluum, then the correction for the interval will be the differences between the series properly and the middle series, as represented in the fourth column: I AI AI^ Correction to observed interval. — 8 — 64 7 1 1 63 6 2 4 60 — 4 4 16 — 48 8 64 + 4 12 144 + 80 6 14 196 i:i'2 7 15 225 161 + 8 16 256 + 192 2' = 800 In comparing the residuals, it will be seen that the correction applied on account of cooling has improved the final result considerably.

KXPLAXATOUY KE:\[xVrJvS AXl) KE('Oi;i) OF OBSEliVATIONS. The iieiululum was swuiii;' at Polaris llonse in tlio sauie way as at tlic' Tolaiis Bay (>liscr\'a- tory, the period of observation in botb placi's coniprising ciglit days. Owiup; to our unfavorable situation after the disaster liad occurred, we were not able to build a proper obserA atory, but liad to eoiidiict the experiments under consideration in a hut, containing but one apartment, which was our bedroom, parlo!-, study, and kitchen for more than seven months. As this room, if it can be termed sncli, was t:(cni)ie selec^t for our CiWscivatious the houis while tlie men were asleep, as the atmost quietness is required in conducting ex])eriments (if this kind. For this reason, we were unable to obtain two sets of obs(n'vations, as we did at Polaris liay, and we hope that the dreary circumstaiu'cs ought to excuse this negh'ct. The pendulum was mounted in the same way as described in the course nl the Polaris Pay observations, exce])t that the steel bars used there to steady the box were supplied by Avooden braces. .V sipiare hole was cut in the floor of our hut, near its northern wall, into which a piece (if strong timber was put, ccniented to the soil (a bixiwn syenite) by means of water, which frozti very readily, and the box containing the instrument was placed on the pier thus obtained. The pendulum did not swing in the meridian; the vibrations being performed in a direction about northeast and southwest. The swinging knife-edge was about ele\"eu feet abo\e the mean sea- level, and the telesco]M>, b.y means of which the transits were observed, was screwed to a carpen- ter's tool chest, three leet to the light of the pendulum. Each series was commenced with a P. vibration, as had been done at Polaris P.ay. The chronometer used was compared before and after the respective sets were taken with three other box-chronometers, as is shown by the record of com])arisons. Mr. Pryan occuiiied tlie tclesco])e; the writer, the chronometer. 72 Pl.NDrLrM-lCXPI'RLMKXTS Set I , tiivr 1, nnvi Il ■> , int;{ K ]. i;. L ''• in. s. h. ill. ■s'. /(. Itl. s. h.

Schott, which ai'e coutaiued in the following letter addressed to Mr. J. E. Hilgard: Computing Division, Coast Survey, April 25, 1871. Dear Sir : The followiug results for number of vibrations (in a mean solar (lay) were obtainetl from observations with the Hayes pendulum, made here on six days by myself, assi-sted by Dr. Walker and Mr. Scott, The reduction was made by Mr. Main. The method of observation and computation is the same as that given in my discussion of the "Physical Observa- tions in the Arctic Seas, by I. I. Hayes, M. D.," etc., Smithsonian Contributions to Knowledge, Washington, June, 1867, The pendulum is swung in four positions, and the number of vibrations in a mean solar day are referred to a standard temperature (50-^ Fah.) and to a standard atmospheric pressure (29.8 inches). Each result consists of four sets of eleven transits of ten vibrations each at the beginning, and the same number at the end, of an observation; the inter- vening time being nearly four hours, during which a number of transits were taken to keep account of the number of vibrations. During any of these four-hour terms, the temperature hardly varied as much as 1°. All possible precaU' tions were taken to insure accuracy. The principal remaining source of error is that of irregularity in the rate of the chronometer. If the correction for rate at the end of four hours is but + 0".5 out, it will make as much as + 3", or nearly +3 vibrations, in a day. The accordance of the several results on different days shows that the chronoraefer could bo depended on within half a second. On the first day (April 8), the number of intermediate readings for numljcr of vibrations was found insufidcient (for want of assistance in observing); hence two sets were added on April 21 and 22. The sis results for "First knife-edge supporting" are of the same weight as the four results for "Opposite knifo- edge supporting." The numbers N, for face 1 and for face 3 (swinging), should theoretically be the same ; and after reversing the pendulum, end for end, the numbers N', for faces two and four, also should be the same. In fact, we can regard them as two independent pendulums. The results compare directly with those deduced by me for Cambridge, Mass., and for Port Foulke, Greenland. Originally, I had designed to observe four times for each face, but found it too laborious (considering other duties) ; yet I think the final mean value is sufficiently reliable.

The combination Cambridge— Port Foulke gave the compression ^ ; the combination Washington— Port Foulke, i. The true value lies between, but nearer the latter value. The local deviation in gravity appears, therefore, to 250 affect Washington and Cambridge in the opposite direction, but the latter considerably more than the former. Obser- vations at a greater number of stations will probably bring out the fact that the number of vibrations at Washington are too many, those at Cambridge too few; in other words, force of gravity at Washington greater, and at Cambridge less, than the normal value due to the respoctiv(5 latitudes. The pendulum is now ready for shipping. Yours, respectfully, ^j^_^g ^ SCHOTT, Assistant in the Coast Survey. J. E. HiLGAED, Assistant in the Coast Survey, in charge of Uffiev. Altliongh the preceding experiments (at Polaris Bay and Polaris House) were couducted witli the utmost care, and the transits accurately recorded, as may be proved by the probable error, not exceeding 0.3 vibrations in one mean solar day, we still did not succeed in getting a satisfactory result by combining our observations with those made with the same pendulum at other stations. 100 TENDULUM-EXrEEIMEETS The following table contains the result of the number of vibrations performed by the llayes pendulum at different stations: stations.

Mr. Bond's preliminary observations, however, are not published. Assuming that the excess could be increased by the nearest even number of seconds, a revision of Mr. Schott's reductions of the said observations would give 8C450.3 vibrations. At Port Foulke, a similar uncertainty must have occurred, and the result obtained there might easily be brought up to 8C5G8.7 by increasing the observed excess also by the nearest even number of seconds; assuming, besides, the chronometer-rate to be uniform, instead of showing the great irregularities as gi\en there. If we could assume tliat, in the course of observations made at Polaris House, R and L had been mistaken in the series marked —4 and + 4, then the result would come up to 80568.1 vibra- tions, although with larger residuals, which, nevertheless, show a certain regularity. The latter may be explained by a regular change of temperature, or an acceleration in the rate of the chro- nometer, or that the knife-edge of the pendulum might have rubbed against the wall of the bos in which the pendulum was swung, or that the force of gravity might have a period, or by a combi- nation of some or all the causes mentioned above. At Polaris Bay, we find the difference between the odd and even faces just contrary to those found at the other stations, indicating that E and L might have been mistaken in the middle series for the odd faces only. Assuming the latter (although this is scarcely the case, another explanation might be found in one of the above causes), we find 86573.6 vibrations, which would make the dif ferent results agree far better, not only among themselves, but also in their differences. Making use of the well-known relation existing between the earth's compression and the number of vibrations performed by the same pendulum in a mean solar day, we obtain the value of the earth's compression to be— 299.5 agreeing closely with Bessel's result, which is— 299.2.

Of an extnisue serirs of iii;\ym4ic dliseiA atioiis, iiio.stli, luaiie at tlie Polaris Bay ohseivatoi',, only tlir siuall muiilii;r of a.Listthitc (k'tL-riiiiiiatiou.s, of euiiiparatively little \-alLie, could be Kaxxnl wliieli we pi'o[)iise reeordiu.u lieieaftei'. Uefoie doiuy- su, however, -.ve may be peiiniUed to aiakc a few ri'iiiaiks iii re.^ard to tbe mode of olisei\ ati<.iii aud ou tlie eliaiaeter of the majj;netical phenomena of the said locality, as far as such leiuaiks caLi be uiade without dtawiiiy fioiii any othec souice than memory. A short tiiue after the meteorolo^ieal and astrouonueal ubseiAatory had beeu erei'ted, two suowliuts were built (compaii' i;rouud-[)lan of the obser\-atory i;i\eu in the chapti'r ou the "TemiieiatuLe of the An"). The easteruinost of tliese huts contained the di|ieiiele, while the declinonieter was mounted iu tlie other; but the re^idar obseivations on the \ariatioii of deelina- tiou could not tie beLiuii before January, isTl-'. It wTbs oar inteutioa to l.ie^iii earlier; i)ut a heavy northwest gale, which brouj;ht the ship in (jiiite a perilous condition, iu Xoveinber, 1871, carried off the domes of our magnetic huts, ou wliieh occvision the declinometer was damaged. This clr- cuiiistancc and the pendulnnl-ob^ervalil.lns prevented ns-liniii beginning the maguetieal observa- tions before the time stated. After the ex[)erimeiits ou \ibratiou had been completed, the declinometer was mounted by Mr. Bryan, and the observalious ou variation of dccliuatiou were begun toward the middle of Jauiiai), ISTL'. Instead of couducliiig, howe\er, the obserxations iu the miumer proposed iu the iiistnulions, which, under the ciriaimstanccs, would never lia\'e \ ielded any satisfactory results, we iireferred to take hourly readings ; the observations being made by iMessrs. i^Ieyer and Biyau and tlie writer, each person oliserxiug generally for eight hours at a time. IJesides these hourly observatious, we otiserved three term-days cNcry niontli, according to the Goettiugeii regulations; one of these term-days corres[)onding to the day adopted by all I lie magnetic stations. The observations were kei)t up till the t'lid of .May, when they hail to be-dis- coutinued, because two of the obserxers went ou the boat-jouriu'y towartl the inuth. As it seems, the maximum west detlectiou takes place between B' aud 5'' p. m. aud the mini- mum between 3'' aud B' a.m., contrary to Port Boulke aud A'au Kensselaer Harbor, where the maximum occurs at aboht 1'" p. ni. aud the minimum near midnight. At Polaris Bay the West declination =9G^ and the Inclination = Sl^ li."/. During February, ISTl.', great uiagiielic;d disturbances were noticed, amounting in one instance, on the morning of the -1th, to about 'J-', ^\llether these disturbances wme due to the approach of the sun to tlie horizon, or to inxisible auroras, is ditlicult to decide. On February -1, when the greatest disturbance ociaared, a very brilliant auroral dis[ilay was noticed, beginning lietwecn 7'' aud Si' p.m., and ending between ■'>'' aiuKJ'' the Jiext moriiing. During the time this phenomenon took place, Mr. Bryan was stationeil at the magnetometer, li,i\iiig a string tied around his arm, which was carried through the door of the hut to the writer, who observed and recorded the changes of the aurora, botli observers being pro\ ided with chroiunuelers. Two distinct coronas formed, and, after the disa.p[ioarance of each, the greatest dellection of the magnet was produced. To gi\c the exact amount of dellcctiou is beyond our means. The few absolute determinations given hereafter were mostly made with two prismatic com- passes (counting from S. through F.), manufactured by James Green, New York, aud by B. Oaselhi, Bondon. The greatest jiortiou was obtain-d by :\ir. Bryan: aud, whenever the name of no other observer is stated, the determination was made by hiai.

PSYCHROMETRICAL TABLES, IN ENGLISH INCHES OF MERCURY, THE ELASTIC FOECE OF VAPOR CONTAINED IN THE AIR, ITS IIEI.ATIA E llUMIDri Y IN IIUNDIIEDTHS, AND ITS DEA¥-POINT. INTRODITCTORT T Inasinucli as it devolved upon us to reduce about 18,000 psyclirometrical observatious, most of which were taken at temperatures far below the freezing-point, the want of useful tables became very noticeable. There are extant certainly very satisfactory collections of tallies, e. (/., tbosi' pre- pared by A. Guyot/ Moritz,^ and Glaisher ; ' but they were not found to answer our puriiosc. As our observations were mostly taken at low temperatures, Guyot's tables would have been of no service, unless laborious interpolation had been made, occupying a great deal of time, because the horizon tal difl'ereuces there given amount to 0?o F., and the vertical to l';0 F. :\Ioritz's tables, s]ie- cially calculated for low temperatures, are given in degress of Celsius; aud, as all our observations were registered from instruments provided with Fahrenheit's scale, it would have cost much time .and labor had we atteuipted to convert our readings into ceutigrades. We felt some hesitation to use Glaislier's tables, because they are based upon empirical factors, and do not furnish as ;i<'eurate results as they would had Regnault's constants been used in their calculation. For these reasons, we considered it necessary to construct tiie following tables, primarily for our own use. \Ve offer them hereby, however, for others that may be following the same line of observations, in order to save the time and trouble that would be required for another calculation. The tables are based upon Regnault's constants,-" aud furuisb, by insi.ection, Kdative Humidity, Force of Vapor, and Dew Point for each tenth of a degree. No further explanation as to tlieii- use is rerjuired. We will only state that the values were mostly calculated from O.'l to O.'l, and the alternating ones were interpolated.
