In speculo teipsum Contemplare Dr. BLACK. A Looking-Glass for the Black-Band of Doctors. Wherein may be seen the Ignorance and Malice of these Physicians, who have Clubbed under the Name of Dr. BLACK, for suppressing by their Scribble, and other Calumnies, so great a benefit to the World, as the new Cure of Fevers. Contained in a 2d. Letter written by Philander to his Friend in the Country Philomathes. In Defence of Dr. BROUN.  
EDINBURGH, Printed by the Heir of Andrew Anderson, Printer to their most Excellent Majesties, 1692.

When every Schoolboy knows this wise Precept, Learned Club, you cannot be Ignorant of it: But surely the Reason why you have so much slighted it, must be, because you have by the like Rapture of Learning, that you expounded Philander, (making thereof fool Andro) Taken Biantis for Banters, and Pirenensis for pire nonsense.   

Advertisement by the Publisher TO The READER.  
ALbeit the Clubs Dialogue written against Dr. Brown, contained as much Impertinency, as might justly have moved any Man of moderate Mildness and Temper, to have Retorted it with the like. Yet Dr. Brown would so fat surmount these fools, who had no reason to be provoked, that he would not be provoked though he had reason, and so there was in Philanders first Letter, a discreet, pertinent and  Answer given them, wherein no man was touched. This Discretion, and Moderation, it seems, served then to no other use, than it doth to all Brutish, and Degenerous Spirits, to heighten their Insolence, as appeared by A 2d. Essay, emitted by them, a great deal more Infamous and Scurrilous, than the Former. Which, albeit it appeared very Ridiculous to all Wise Men, yet in regard, a great many of the weaker sort of People, could not but be exceedingly amazed to see so many Physicians, that pretend to no small Figure in their Profession, Redicule an Improvement about the Cure of Fevers, made so Plausible by Dr. Brown and himself, Represented a mere Ignorant, and Impostor; this, as it proved very surprising, and astonishing, so it makes it very necessary, for satisfying the Curious, that there should be yet some Considerations offered, concerning the Buzle made about this very great Concern.  
And First, It being plain, that although this Point of a most effectual Method of Curing Fevers, be of great Import to all Men, yet there are very few able by pehetrating into the Mystery of the Debate, to be Competent Judges thereof, the most part do therefore, by Implicit Faith, acqu●●ce in the Authority of these, they think should, and do know this matter thoroughly.  
Yet as, Delirant reges, plectuntur achivi,  
So 
When Doctors rave  
They fill the Grave.   
For oftimes Physicians by their ascendant over thevulgar, having patched up an Authority, calculat only for self Interest, they do thereby most Severely and Successfully Tyrannize over Improvements, and their advancers: In regard they are jealous, such Improvements come to Supplant them, and steal away their Gods of Profit, and Esteem.  
And next, since, in consequence of this, there seems to be no means left to Extrica● this Improvement out of the Pounces of such Cormorants and Harpies; but to represent them to the World, in their Natural and true Shape, and despoil them of their borrowed Plumes of unmerited Esteem, acquired through vulgar Ignorance, and Mistake.  
It seems absolutely necessary, for undeceiving the the World, and rescuing the true Interest of Mankind, to give Exact Characters of these Blacks, Wolf's in Sheep's Clothing, and Enemies to Men, at least in so far as their Scribble and Calumnies declare them.  
And so there being only here represented a true History of Dr. Black's Phenomena, and these plainly solved, by laying down a solid Hypothesis of his Nature: I hope the Candid Reader will not Construct, that Dr. Broun is provoked, or that he intends Reviling for Reviling: but only that he designs, for the Public Good, to give a true Representation of the weak Foundation of that Tyrannical Authority, which in its being is Calculated, and Contrived, and in its use is most advantageously exercised and employed, for the Overthrow, and Suppression of so great Benefits, as Improvements in Medicine are; Their safety and progress being indeed no ways attainable, so long as men that can securely levelly at Self, and private ●nterest, although at the public Coast, remain in Power and Credit with the World.  
Philander has not gone to beg pitiful stories at the Common Strumpet Fame, to make up their History with, where perhaps he might have made als good purchase of Reproachful Tales, as Black has done, (none of the Black Club being either so Innocent in themselves, or such Darlings of Fame) for  
Tam ficti pravique tenax quam nuncia veri.  
But he has only made use of such Documents, as are drawn from their Writings, and other Actings about this Affair, and when no body is Named, if they hit not right, there is no miss made, and no body can Complain. And because Dr. Broun was unwilling to expose these Enemies of Truth, before he essayed all means for their Reformation, and endeavoured to beg Peace at their hands, long before they were Printed, he gave in his whole Papers to them, to be Considered, with the following Letter annexed thereto.   

To all Physicians that are Dr. Broun's Enemies, or these who have Calumniat him by Printing against him, or otherwise, A Charitable Offer of Forgiveness and Peace.  
THat Scurrilous Dialogue, Printed and Dispersed, with design to suppress my honest Endeavours in Relation to the Advancement of Medicine, and wherein you have been concerned, as Contrivers, Authors, Publishers or Approvers, I studied a while to connive at, and to give it so General an Answer, as might not reflect particularly on any of you, either directly, or by broad hints: Tho my Vindication in the Opinion of some, seemed in so far defective, that it stood merely on the Defensive, and not paying you home in the same Coin, wanted some trappings of Raillery, to have made it more Fashionable and Passing (that Raillery being always flat where no body is hit)  
Until your 2d. Essay a great deal more Impertinent than the former, backed also with with your constant verbal Calumnies, obliged me something to change the former Measures, and to give this Answer, which (as intending to be more Generous, than at a stolen Dint, to make any of you Ridiculous,) I have sent you before it be Printed, to be perused: And if there be any thing therein you can evince Impertinent, either to my Vindcation or the Vindication of the Improvement, I endeavour to advance, or a more severe Retaliation, than the Provocation Craved (your Scurilities and Calumnies indeed admitting of no other Answer.) I am content (as being willing to do my Enemies all Justice) it be in so far Reform.  
There was never any man's Reputation designed to be Impeached by me, unless in so far as it's Employed to bar out Improvements; Some of your Reputations, I endeavoured to advance pari passu with this Improvement; But If any man's backwardness, becoming too plain, deerogate from that Portion of Reputation he is in possession of, he knows whom to blame for that. When Discoveries, and men's Reputation turn Antipods, and opposite, the Discoveries tending to the Zenith, their Reputation will down to Nadir. And the greater Pouther be made about Discoveries, when they become Conspicuous, their defects will be the more Legible that make it: And as common Prudence would oblige all that have common sense, rather hover a While, than precipitantly condemn matters of Experiment, which others have found, but they themselves have never seen; So indeed I think a very small touch of the Conscience of your Duty, as Physicians, would make you carefully watch all opportunities to observe whether or not this Practice hold to be as Successful, as it is given forth, & this (which is very strange,) none of you has ever yet taken the pains to do: And so how you can Answer, either for this neglect, or for your other behaviour in this matter, to God or Man, I truly do not understand. If I have wronged any of you, I am content of just overturs for further satisfaction, than what already you have taken at your own hands, if further be due: And if you cannot make any wrong appear (which I think ye will not) I am content that being least in the Transgression, I have the honour to be first in the desiring a Just Accommodation. It may be sufficiently known to you, that I am several ways (especially in regard of the cause) so advantageously stated, that I need not fear your attempts any other ways, then that they may hurt yourselves, and prejudge a while the advancement of Medicine. It's therefore Peace and Charity to you, and love to the Public Good, moves me to this Advertisement,  
Since than I am content on very easy terms to pass from any Retaliation, or exposing you, as here you see, as this I conceive, will be a considerable evidence to the World, of my Peaceable and Charitable Disposition, so it will be a pregnant Testimony of my affection to the Art which by a Representation of the Matter, or a just Retaliation, may perhaps come to suffer: And show to all Men, that (like Solomon's true Mother, that would by no means endure the dividing of the living Child) that I am so tender of the Art, that I incline scarce at any rate to do aught that may tend to the exposing, or vilifying thereof; and further, these Considerations (as I humbly conceive) ought to invite you also to give the like Testimony of your peaceable Disposition, and of your like tender affection to the Art, in reasonably preventing, what may any further mar the Honour or Advance thereof.  
If your return to this Letter, be any thing but Peace, and Accommodation, you may expect the World will be acquainted with it in Print,  

THe Clubs return to this, was in their old chat of reproaches, some of them, especially the Lame and the Maimed answered it in a new Cant to the Tune of Cudgelling, and Ear-cropping. O brave Doctors, who, having long since Banquerouted your Learning and Reason, took first refuge in Ba●ter and Ribaldry, and now being banged out of that, has no shelter left you, but to thuart nature so far, as to give yourselves out for Hector's!  
And so Candid Reader, I crave pardon for detaining you so long in prefacing to Philanders' Letter, which will more sully give you the account of the whole matter, and so bids you adieu.  
Your humble Servant, Philarchus.

LEarned and Witty Club, when I reflect, how Ingenuously you deciphered Philander, just as a Mountibank's Fool would have done, taking it for Fool Andro. I would earnestly entreat, that ye do not Sore again so high, with an Icarian flight in Learning, and take this Philarchus for your Fool Arch, that mere Pageant of Learning, who being on of the Authors of that Learned Dialogue, written against Dr. Broun, thought to escape his Reward, because he was sheltered in a Chair; yet the Impudent Pretender Declaiming, or rather Belsching from the Chair his Foppry and Impertinency, has so well chastised himself, that no body needs to be further solicitous to take any other Correction of him, than by Publishing to the World his Inaugural Oration, with some Natural and Pertinent remarks thereupon; etc.  
Unto which, if there be added, a full plan and History of the Means and Methods of his, most deserved Promotion; as thereby it will be clear, that the Air of our Climate is most apt to blow up Bubbles, letting more solid things fall to the Bottom: So such a History as this will not be little delghtful to the Curious, to understand plainly all these petty Arts, and shame Tricks, by which this a●e of Learning managed his Intrigue of applause Catching, and fame forstalling.  
If Hogen Mogen finding the pleasant Effects of this Pretty Art, complain that they are gulled, and that for Juno they have embraced a cloud. I must crave Mynheer pardon, if I tell him, that he must not think himself abused▪ by these who gave the Man a brave recommenoation, for the Scots Proverb, and Practice is, that these who are ill of their Harbour, a●e best of there away Ken; and indeed the easiest way to be easily rid of atroublesome Guest is always to ruse him.   

A second Letter Written by Philander, to his Friend in the Country Philomathes in Vindication of Dr. Brown.  
Dear Philomathes.  
I Was not a little surprised as well as yourself, when my former Letter written to you, and Published to the World in Vindication of Dr. Broun's Book, was Answered by his Opposers, to whom it was not Directed: Animadversions, or Observations thereon, the Black Dr. might have Published, but his giving an Answer of a Letter not directed to him, seemed a nonsensical piece of business, I ruminated long to see if this Bull of the Black Drs. could be any way excused, at last I think I hit it, for seing how Learnedly Dr. Black had deciphered Philander, making it Fool Andr●. I clearly understood, that the Black Dr. after the same manner, had deciphered your Name Philomathes, taking it for Fool Matthew one of their Society: this surely has made them rather Ignorantly, than altogether Impertinently Answer it, though by as great a mistake, as if one should take Dr. Black for a Candid Dr. or White for Black, there being as great a difference betwixt Phiomathes and Fool Matthew, so, as the Clinking of the Bell makes the Fool think, does, the gingling of Words make these wise Drs. rave. And now Philomathes, it were in vain to tell you how Infamously these Drs. in their Scurrilous Libels, bestow their Talon, and bewray their little Wit: every body that doth not, will fully shut his Eyes, must of necessity see every Line of these reproachful Stories against Dr. Brown, drawn in the black Characters of Envy and Malice: and surely, because Dr. Brown's Enemies could say little in the cause, and bring less against his Ingenuity, and Sincerity, they endeavour to  his extrinsic Qualifications, his Discretion, his Humour, o● his Carriage, as if by making him Ridiculous in any of these, they can but abate men's Reverence to him, their Confidence in him will not long hold out: For as on● says bare honesty, being looked on as a Leafless Tree, no body will trust himself to its shelter: Thus Socrates was treated by his Enemies, when they could not otherways suppress his Reputation, they hired Aristophanes the comic Poet, to Personat him in redicule on the Stage.  
And indeed I think no wonder these Gentlemen, for all their Impudence, had never Confidence enough to own to the World what they had done against Dr. Broun. all Crimes have had their Fauters and Abettors, but Lying, especially reproachful Lying, is so much the Dregs and Refuse of Wickedness, that none has yet had Chemistry enough to Sublime it unto Reputation, so as any body will ●enter to own it: and among the several Aggravations, this Crime is capable of (besides the cause a Man suffers reproach for) the putting of such reproachful lies in Print, seems none of the least: But let George Mosman look to that.  
I must confess, we are got into a very Merry World, if Men will be so foolish, as to suffer themselves at the expense of their Health, the most valuable concern of Life, to be laughed and lied too, out of so useful, and clear an Improvement to the Common Nature, as the Cure of Fevers. Dr, Broun has in his Schedule, given an Idea of: I am willing to believe, there are a great many still, who have perspicacity enough to see thorough such sort of Addresses, So that these Merchants will lie under a necessity to deal with the more Ignorant Chapmen, and with them their Counterfeit Wars will go best off.  
But pray let us take a sober view of what these Fops, and Enemies to Mankind will be at: Here then, good Drs: Let us carefully weigh the matter, and lay in one Scale, the dearest concern under Heaven, the Health and Life of Men. and their nearest Relations, frequently overturned by th●se continual Fevers, the danger and precipitant Invasion thereof; which by a sudden Eruption and Devastation, in a trice overturn our Hopes and Comforts, do therefore make the loss of Life more bitter: and which is yet very recent with many, your former and present unsuccesfulness in the Cure of these Fevers.  
And in the other Scale, let us lay the undoubted Obligation▪ chargeable on the Adepts, and Sons of Art, to Ransact and Muster all the Supplies, Study, Industry and Observation can make up for the Resistance of the sudden Ravage and Dissolution made by these Fevers: together with the great, constant and daily Success, which to the great Comfort of Men, and their Relations, is observed to follow this new Method of Curing Fevers.  
Now, my very good reversed Friends, to which of the side does the Balance incline to with you, and since you either close your Eyes from the wonderful Effects of this new Method, or dissemble, what you understand of it, are you not then in love with these many Ruins, and Distresses these Fevers bring along with them, and content to let your Blood freeze within you, in the midst of such extreme heat, when upon every trivial occasion, at other times, it's ready to break out in the strangest Ebulition: Is not this to prove yourselves Fops, your Art ● Trick, and Induce the World to cry out, you can do nothing, when there is most ado with you: Good Doctors, who appear to the vulgar sprightly Heroes in Medicine, I amal mostina fright, when ● consider with all, what a rem●ra many such dead weights as you, really is in the way of true Practical Improvement in Medicine, to the great hurt of Mankind, and the scandal of all faithful Physicians, you are in truth, the dead Flees that Corrupt all their Perfums: For shameimust honest Dr. Broun meet with such dishonest treatment from you, for his Charitable Endeavours, to deliver the World from the fetters of Prejudice▪ and Ignorance, & wherein no Man is touched or wronged; it's not his own things he seeks, it's the Interest of Humanity, in so noble a Discovery of a new and most successful method of Curing these formidable Fevers; So the mali●e must be strange and more than humane, that prosecutes him.  
Since than Philom. as every body knows, this fearful havoc of our Dearest Concerns made by these Fevers, often falls out, under the Presidence and Government of the Physicians, and seeing their Trust makes it nearly their concern, to inquire seriously, whether Negligence or Mistaks may be Concuring to the Course of so sudden and formidable a Devastation: and also,  we perceive Men are always with great difficulty, drawn from their former Customs and Practices: and with all Ranks and Stations of Men, Improvements are hardly entertained and ●mbraced; but most of all, with those whose Esteem, and Reputation can be preserved entire without their entertaining them, as in Medicine, I apprehend it's too easy to do.  
Upon these Considerations Philomath, I am not only clearly Induced to entertain shrewd and harsh thoughts of those that are offended at the Preliminaries of Dr. Broun's Book; but I also think, he has made no Impertinent degression, but a very necessary Preliminary, and Preface to his Work, where he has made a tower to Summoned up the whole Force of that Obligation, lying on Physicians, to Diligence and Improvement, to conjure down negligence, and to areaign all vulgar Errors and Mistakes capable to stifle, or deprave Improvement in that Art, it being indeed the●e that seem like Mountains, to stand in the way to Improvement; do they not then deserve by serious Consideration, to be Leveled and Removed.  
Now Philom. Knowing you are a Curious Enquirer into the Causes of all the various Phenomena of the Civil, as well as the Natural World; and that the behaviour, and Nature of these Blacks, pretending to be Physicians, may appear very strange, and un-accountable to yourself, as well as others, and put many in hazard to think, that all which Dr. Broun has offered in this matter, is nothing but Delusion, and Foppry: I judge it not Impertinent to offer you my unbiased Sentiments, in Relation to a clear, and Rational Solution of these men's Actions, and Phenomena; by giving a solid Hypothesis of their Nature, whereby, I hope it will be plain, that the Dignity and Excellency of an Improvement in Medicine, may not only be very consistent with snarlings and reproaches thrown, thereupon by Interested and Biased Physicians: but that all eminent Improvements are necessarily attended with that fate: so Philom, I realy think the World is not a littl● indebted to the Man, has the courage to make the venture to bring such to see the Light. For it is no more Plain, than it is Lamentable, that after the Laborious Penetrating of the Judicious, who raking the Bowels of Nature, has digged and refined any Improvement in the Cure of these Fevers, (perhaps of more value than all the Gold of the Indies) out of its Natural Min and Oar, where it was hid and Inaccessible by the Block and Sluggard, yet before it can become acceptable, and of general use, it's put to encounter various Skirmisies, with the several Interests, Humours, yea Caprices of Men; and not only every Dunce or Fop has an Itch to slain and fully that virtue he could never imitate, yea, scarce comprehend: yet he (as sufficiently qualified to encounterfit the Physician with the vulgar) is in a great measure capable to disgrace it, but even these that seem more Polishe●, & Refined, and have Engrossed any Esteem, finding a new Title of applause in favours of the undertakers, necessarily follow such undertake, shrewdly suspect it, as topping and veighing with their Reputation, to be at their Coast, and they Endangered thereby to have their merit Eclipsed: this raises such a Torrent of Heat and Envy against it, and its advancrs; that they are often made to stagger under them: and where the thing is so Conspicuous, that they dare not meddle with it; and also finding it would be dangerous and fatal to themselves, to make a quarrel of a man's virtue; they can, by means of their Art, and Authority, by a devilish Chemistry, Extract and Pick one out of the most Innocent Deportment to bespatter his Merit, and which will also serve them as a Cloak for their envy, and malice to the boot.  
Thus men to save the borrowed Lustre of their Skill, fully their Candour: which although a stain little Conspicuous ●s yet very dangerous; in Physicians for Ingenuity the common spur to Industry, the Parent of Skill, being languid in them; it must only be by the favour of Artifice, and Popular Error, without any solid worth, that such have thorough time (which vulgar opinion makes to ripen the most insipid of them) scrambled up to any Eminency, and Enhanced the Opinion of Experienced: But considering the false bottomed Reputation of these Parasites to fame, is like fairy Money, which is brought in a night, and carried away the ●ixt: no wonder if vulgar humour▪ and applause that has set them on the Tottering Pinnacle of unmerited esteem do as easily, but far more justly▪ throw them down again. And indeed Philomath, I am tempted to tell you, that ●hink true worth, as it spares no Labour in acquiring, so it saves no Coast to welcome true Improvements: and is always among the first that shakes hands with them. Whence it may be clear, that what ever benign aspect such Discoveries may carry to the World, yet if they bear in reverse aught Malevolent to any Man's ill acquired Esteem, or private Interest, a cold welcome is to good, nay a very hot one they must look for, from such Men: A clear evidence (among any others) of this, was the Quarrels, Contentions, & Skirmishing, that arose about that merely Theoretical Improvement the circulation of the Blood, And if it far so here, how will it go, if an useful and practical Improvement offer to set up the Head, and the Devil's Game, as well as Man's be marred or these Traps, or Snares that Precipitate Men into the Kingdom of Darkness, be in danger to be removed, by any Considerable Improvement in the Cure of these Formidable Fevers: then well see, as Dr. Broun Intimats further in hi● Preface to his Book: That the Serpentine Brood, which is still big with Malice, and Envious of the good of Men, and and which was never more Dominant, than at this time, will raze all the Corners of the Infernal Pit, for Venom to bespatter such a Project, and its Advancers with. And so the Interest both of Men and Devils being at the stake, and both being attacked by this Improvement in Medicine, no wonder (as the French King and Turk have done) That Men and Devils Confederate against their Common Enemy Practical Improvement in Medicine.  
Now how far all this may be applied to Dr. Broun's opposers, any that will be at the pains to consider both his and their Papers, may very easily Judge: and if thereby, they clearly understand, that in advancing one of the most desirable Concerns of Men, he is as pertinent and solid in Reasoning, than they to depress it, turning quite from the Subject, are pregnant in vile railing and Cavilling, they will not hover long to give their Sentence.  
After my former Letter emitted, and Published in his Vindication, and in Answer to their Dialogue, and wherein the new Method was confirmed, by several Examples, it was thought Impertinency, was by sound Reasoning, so dashed out of Countenance, that it durst never appear any more on that Errand.  
But▪ 2d. Essay, a great deal more Impertinent, and Infamous than the former, made all Spectators understand, that no Humane Reason can tame Devilish Insolency, and that it's as hard to check their scolding humours, as it was to Crub that brazen Zantipes Vein, whose unruly Member, after her Husband had several ways (but all in vain) endeavoured to ●ame (she still calling him Lousy Rogue, Lousy Cuckold) at last he tried her with ducking, but she putting up both her hands, above the Water, and joining the Nails of her Thumbs in a Crackhouse posture, shown how little she was dantoned. Even so these Men, when they are plunged over Head and E●rs, in the derision of all sober Men, still attempt to give the most ridiculous ven● to their Impertinent cha●t. And withal the most favourable Construction can be put upon their behaviour seems this: These Blacks being such a waspish venomous Kind o● Creatures, that when they are Irritate, (which is always upon the appearance of any good to the World) the Venom Ferments and Works so within their Breasts, that it's ready to burst them, unless it break out with a Ratle at railing Row: And notwithstanding Philomathes of all the venomous Eructations, and Floods of Viperspaun, disgorged against Dr. Brown, by one of these Blacks, a bitter Viper: I heard say (which I think a very strange Phinomenon, that the Paroxisms and fits use to be so violent in him still, that he is forced to be keeped elasped in Iron Bands, for without these, his Fits, like Gunpowder, would make such a sorrowful parting betwean poor Back and Breast, that the old sitten on Friends would never meet again, In speculis contemplare teipsum, Sin deformis id morum pensato pulchritudine: audito multa, & loquere pauca.  
Mistake me not Philomath, as if I intended, transgressing all humanity, to insult over any Man's Personal Defects; no no, but being to solve the Phenomena of his Wicked Actions, I am necessarily led to his Cursed Nature, which having undoubtedly depraved his Shape and Body that lodges it (a discreet Guest indeed) no wonder it spares nothing it falls in hands with; and indeed I am tempted to take the Liberty to tell you Philomath, as bodily defects in my Opinion, lay a double Obligation on the Subject to Discretion and Virtue, and the virtue such, are endued with, not only gives a Proportionable Supply of their other Defects; but is also itself more Conspicuous, and renders the Person more Amiable, so wicked Malice, making them justly more Odious and Abominable; makes Reasonably all their outward defects, more Remarkable, and that Common Saying, Cavendum ab his quos Deus & natura notarunt, though it may Justly have sometimes its exceptions, yet I think without breach of Charity, I may be Confident this Subject is none of them; for that Viper, without any Provocation, but his Conscience of honest Dr. Brown's Ingenuity and Zeal for the Public good (Which is I confess enough of Provocation to a malicious Brat) has by Printing, and all other ways, employed the utmost efforts of his Devilish Malice against him; as may be seen thorough all the Clubs Papers, whereof the bitterest and most invective Passages are the Hissing of this Viper, butekpecially may be seen in the account he gives of my Lord Crichtouns Case, which like a venomous Serpent, in the pride of his Bunches, and Majesty of his Scales setting up his brisles, he fronts with this Malicious and Venomous Hiss. (the baseness of Dolphintouns temper) as if he intended the effect of his malice should not die with Dr. Brown himself, but should descend to his Heirs, who appearantly may have the Designation of Dolphinton after him: But as Dr. Brown may justly glory in the Cause he suffers for, so may he do in the Instrument he suffers by; and he will be highly unjust both to his Cause and to Mankind, if he do not acquaint the World, that their Calumnies may have the less Impression, what kind of Creatures (Malice being indeed t●e highest degree of Baseness) the principal Adversaries of his Cause only are.  
But considering, that the Devil rages most before he be cast out; this gives equally a presage of Dr. Brown's success, and makes the Efforts of his Instruments no ways strange, or unaccountable. And in sum Dr. Brown needs not grudge his Enemies should Commence the mostabsolute Masters of Vile Railing, and Disingenuous Cavilling, while he carries it in solid Reasoning, and safe Curing Fevers, which hitherto have been so dismal to Mankind. But he may indeed Triumph, that all these Reproaches and Impertinencies ear so clearly in reverse his hardy attempt for the public good, which these Black Doctors construct is 〈◊〉, first to Devils, and next to there Petty, and private Interest. For any other grounds of their Calumnious Libels, he defies them to make appear,  
Moreover to show how sensible he is of the great benefi● this Enemies have done him, by their Printed and verbal Calumnies, whose perverseness, adding difficulty to his Erterprises, raise the Honour of his Success: and whose Ignorance Characterizing their Authors his Opposers, has for the most part inclined the Judicious to his side: this favour, though done far beyond their Intention, he has most gratefully remunerate, with another not a whit less beneficial to them, but far more meritorious, as being designed and Intentional, and that is, albeit they have named him with all the Names, and Nicknames they pleased, yet he has still forborn to Name any of them, some thinks it's because he is ashamed of such antagonists, but I rather think it's out of Pity; lest there should be a standing memorial of their Ridiculous Impertinencies and Folly, which would so conspicuously Blunder them, when their Embracing both his Theory and Practice, becomes unavoidable, (as in all probability it shortly will) that it might really ●ndanger them to hang themselves.  
But there is one of them that jam truly sorry for, because he ha● had the hard fate to prove so Public a Tool to execute the Malicious Contrivances of the more Politic pates of that Crew, that a Honourable retreat to him, is scarce Possible: for that Man not being able to Contribute any of the least pittance to that stock of sorry will their Pamphlets are stuffed with, was content for his part to Contribute his Pains to drudge at the Press for the rest: and also to do the Office, of the Coal-ste●ller Bo●es, in dispersing their Malicious Papers: Alace, the Club has done with that poor soul, as the willie Pug does with the Cat, with whole Feet he escapes his Chestnuts out of the Fire (and I believe the Monkey was handling the Cat of Sm●●holm, so when she spoke wonders) and to Cool his  Paves, the Goodman of the Club, who had never any great Kindness for him before, (when he thought it not worth his pains to go himself, being in the midst of the Storm) sent the Poor Singed Doctor a highland Journey for him, where he would get Snow-Water, but a Green Burn, like a Green Wound is half whole, behold the end, and that the Titling was not sent along with the Go●k, came from the Goodman's tender care of the poor Titling, who would have certainly been lost in a wreath of Snow, if he had gone.  
There is another effect their Pamphlets has had, which is very pleasant, and it's this: The Apothecaries finding the Club had contrived their Papers so abominably nauseous, that they would easily turn many tender Stomaches begun to suspect the Club had a design against their Trade, and that they might perhaps serve their Patients with Vomitors, and Purges of such stuff, giving them so many Leaves out of one of their Pamphlets for a Dose, according to their Constitutions and Diseases. And this Jealousy was so warm among the Apothecary's Boys, that it had almost raised them in a Tumult to have Rabled the Club.  
As on the one hand, the Black Drs. Scurilous Pamphlets does, in the Eyes of all Judicious Men, evince them the most foolish and malicious of all Men, so on the other other hand, when they come to any thing that's serious, and offers to reach a hit at Dr. Brown's new Theory or Practice, they describe themselves the most Ignorant in the World: and therefore their last Essay was looked on as worthy of no other regard but Scorn and Contempt, yet because the usurped and falls bottomed Authority of a great many Signior Dunces, of that gang; whose Credit lies undoubtedly in Pand on this Plea, does amuse the Ignoant vulgar, who, perhaps making the far greatest part of the World deserve not a little to be Considered and Satisfied, to the end that they may take better measures where to repose the trust of so great Concerns: Therefore it was not thought altogether Improper, to give a further and clearer Representation of that Theory, and the pitiful Reasons brought by the Learned Club against it.  
How ridiculous then are these Men by a few impertinent and incoherent Assertions, bearing in their Front only (its certain) without any other proof, or evidence, and these so mingled with bitter invictives that are able to quite choke the most clear Reasoning in the World. How ridiculous are they, I say, to attempt to overturn an Hypothesis, not taken up gratis, but riveted and founded by a solid Reasoning on the most part of the principal Phenomena occurring about the economy of Man's Body, and these so clearly solved thereby, and made so nea●ly to quadrat therewith, as Dr. Brown's Theory of Fevers in his Schedule, seems to have done; Indeed by their manner of Impugning it, they assure the World, that they never understood it; for any that will be at the pains to Consider it closely (what's in Debate being every man's near concern) will find it an Hypothesis that's clearly demonstrat to include that Metaphysical Consideration, as being most suitable to the Perfection of the animal economy, and Mechanism; and as seeming exceedingly suitable to the design of the Architeck, and an Hypothesis, which has also its Parallel in other Actions of the economy, such as the contraction and delatation of the Pupil of the Eye, and in Actions from Irritation, commonly so clad.  
An Hypothesis that quadrats with the Composition of the Blood, which is made up of many little G●●bules, whose Number, Bulk or Figure may easily be supposed to become vitiated.  
A Hypothesis having the Concatnation of the Procatartick and external Causes of Fevers favouring it, such all ways being apt to produce viscosity and grossness in the Blood and Humours.  
An Hypothesis that's founded in the Consequences of that great, though Insensible Evacuation of Perspiration lesed, and in the Nature and Lesion of Digestion of the Stomach; also both the frequent Causes of Viscosity and Fevers.  
A Hypothesis, by which are solved clearly the natural Penomena in Fevers, such as Frequency of the Pulsie, Heat, Inquietness, Pains, Anxieties, delirium, and Spots. Where, also the Phenomena of helpers in Fevers stand clearly of its side, as first Blooding, and the various Phenomena occurring about it, solved conform thereto, and made to confirm it. As also that Magtsterial Remedy, of Purging, Clearing and Confirming that Hypothesis, with the use and benefit of the Paregorick, and quieting Medicine, Homologating the same.  
Where also it is showed how the Benefit from volatile, and fixed Salts, and testaceous Concrets, exceedingly ●avours this Hypothesis, and also how the benefit of Cupings Leiches and Frictions confirm it. A Hypothesis which has cleared the hurt of the mere Diaphoretique method in Fevers, and where many other Phenomena of Hurters are fully solved conform thereto.  
Whosoever then shall think that an Hypothesis, more clearly founded than ever, I think any yet h●s been, in reference to that subject of Fevers, and which has never been Comprehended, or understood by them, far less Considered or Expended so, as to make them Capable to Impung it) should be overturned by the dash of a few Impertinent I● consequential and False Assertions, concluding with all nothing, against the Hypothesis, they may as well think Arthur's Seat will be overturned bya few Mol-hills casten up therein, by the poor blind Moles, and this I think, will fall in nobody's head, but these that are fully as Ignorant, blind and Blockish, as these black Doctors. And now Phil. civility obliges me to usher in what I am now to take up your time with, with a craving Pardon, knowing you can bestow your minutes better than on such Trash: for no better Epithet can I give what they have said against Dr. Brown's Theory, as you shall easily perceive, by and by, and is mentioned in the Page 13. and 14 of their Answer.  
First, They say That every Part that is Contracted has an Inate faculty to perform that Action which is done, by the Influx of the Animal Spirits into the Fi●res. This will prove a direct Contradiction, an Action to depend on an Inate faculty of the Part, and yet to be done by the Influx of the Animal Spirits, which are quite Extraneous thereto, and in a perpetual Flux, seems clearly repugnant, and als absurd as to say, that a Miln-wheel hath an Inate Faculty to move about, which idon●e by the falling of the Water upon it.  
2. They say next, All Parts when delated do suffer ever, violence from the Humours, and what else they contain, does the Dilatation of the Brain, or Breast come from violence I pray, of what, yea does the heart itself suffer violence from the Blood. These Men are so Giddy themselves that they labour to turn all the Moderate and Benign Motions in Nature making Life, into reeling, violent, and Preternatural ones, they are so much in Love with Jarring, that they dream of nothing but Force and Discord.  
3. They say, That the ventri●les of the heart are of the same substance with the Inner coats of the Arteries and Veins (which is scarce sense) and that they are sensible of Irritation, that the Dilatation of the Heart, the weight, the distension through effervescence of the Blood, doth Irritate it: To say the Truth, this Principal of Irritation, which they most foolishly make the Cause of the natural motion of the Heart, must have its rise from that Irritation raised in themselves, upon the appearance of Truth and Light, whereby, like men that have the Yellow Jandice, who think all things yellow, they think every thing Irritate, when they are so themselves. And there is no doubt, if ye will ask them, ye will likewise find they fancy, that the Sun, Moon and Stars, and all other motions in the universe move from Irritation, yea, bark and Irr too when their Chimerical Hypothesis is Impugned, and that the Harmony of the Spheres must turn Jargon as well as the Heart for Company:  
Now how Ridiculous is this to any Person, but a little acquainted with Speculation, it being plain that the Contraction of the Muscles, is the more natural of the two Motions: For the Resolution of the oposite Muscle is still followed with the Contraction of the other, and the Heart being a Muscle, the Contraction thereof, rather than the Dilatation is a Natural Motion, and therefore does depend on no Irritation, but is the perpetual Law of the Aeconomy subservient to the great end of Distribution of the nourishment to the whole: and is no more from Irritation than the like Conveyance of the Nutrition in Vegetables is. Would it not be brave Philosophy to say, the Sap goes from the Root of the Plant to the Branches by Irritation.  
And further the quanrity of Blood squized into the Heart, suppose a dram is as far from Irritating it, as a convenient Portion of Meat received into the Stomach, which is not se●t out till after Digestion, but then by no Irritation.  
As also the Effervescence of the Blood either in a Natural or preternatural state is a stolen Error, reasonably Exploded by Dr. Brown, according to the bestnew Authors, as Blancard, Bohn, Brounerus, Charleton. And Esservecence being an Intestine Commotion of the minute Parts of Bodies, which most frequently, happens by Heterogeneous mixtures. It can never be reasonably said to be, but where the Senses discover it: pray with which of the Senses did e●er these acute Drs. discover the same in the Blood: if all the World must believe against their Senses with these subtle Doctors, pray let them ●sher in Transubstantiation next, for they have broken the great But that kept it out.  
4ly, They say, This Irritation makes the Heart contract itself, without respect to a final Cause. This is a clear Repugnancy for all Irritations in the Parts, when they are, are Preternatural Motions, from Preternatural Causes, and are raised to rid the Parts offended of the Irritating Martyr, and here Nature may be said not very Improperly to Act for an end, yea, and if such an Irritation, as this were Competent to the Heart, in its Natural Motion, it clearly implayes the like acting for an end, the ●ne end quite distinct from that Employed in Dr. Brown's Vindicatorie schedule: for indeed their Hypothesis obliges the Heart to throw out the Blood to be rid of it, as a Grievance, which is no sooner done, than like Sisyphus Labour malicious Nature sends in another Dash or Squirt to vex it, and this being perpetual puts the Heart in a Continual Chaff at the poor Blood, which comes no sooner into the Heart, but as a troublesome Guest, is immediately thrown out into the Arteries, Irritating them likewise, which presently sends it a packing into the Veins, which having als little Kindness for it are at Continual toil to send it back again to the Heart, Where it gets als little rest; One would think the poor Blood is followed with Hue and Cry, and that Nature is at a Fox hunting with it from Hill to Dail, back and forward, and at Death the Blood, having lost its Legs, is Catched: and so the Game ends.  Risum teneatis amici. 
But to be serious about their Irritation and Vi●●lnce, there two principles of Natural Motion, I pray you Witty Club, what violents the Heart to Dilatation and I●ritats it to Contraction, when it beats, being out of the Body of some Animals, without any Blood, coming in, or going out. This one Instance, if they had read Dr. Brown's Book with any more Attention than the Parats speaks Words, would never have suffered them to slipped so foully. There offering to Answer the Book being an Assirmation that they have read it, I will not offer to Contradict it, as being loath to call them both Fools and Liars, but one of them they must surely be.  
Next they say, That the Pulse that strickes the Finger, is nothing but the Dilatation of the Arteries, occasioned by the Contraction of the heart which is granted, Then they add, for Dr. Brown to say, that in a Fever, the Pulses are more frequent, and yet to say the Circuit Motion of the Blood is more sl●w is great nonsense. O brutish Ignorance, for first, this last Assertion is no ways consequential to the former, though they bring it in Consequence thereof; and next, any that considers the matter will find, the last Assertion a plain falsehood for to say in a F●ve●, the Circuit Motions of the Blood is more slow, and yet the Pulse more frequent, is al● good Sense, as to say, that the strokes of a Pump may be doubled, and yet the Water come out more slowly than at other times it does by single strokes.  
And this Phenomenon in the Pump is obvious to the Senses, with its Cause, for if either the Liquor Pumpe● be more viscuous, or if the Top-hole be not clear, the frequent agitation of the Pump will pour out less Liquor than the moderate working thereof, when the Liquor is sufficiently tenuious and thin, and the Top-hole clear. As also the short and thick strokes of a Pump pours out less Water then long and rare strokes do; even so the Pulse of the Heart and Arteries, although more than usual frequent, may convey less Blood into the Veins, when the Blood itself is more gross, or the Passages betwixt them obstructed, or not sufficiently Patent: then a lesser frequency of the Pulse does, when the Blood, or Passages are not under these Faults. And it's clear that the Pulse is less frequent in health, because, after the Arteries by their Dilatation have beat the touch they are Contracted very near their Centre, and do expel into the Veins almost all the Contained Blood, so, in the subsequent Dilatation, as moving more space, viz. From the Centre to the Circumference, they most of necessity take more time to Dilate, and Consequently seldomer beat the touch, than in the Case where the Blood is with difficulty admitted from the Arteries, into the Veins, because than they Contract Less, much of the Contained Blood remaining, hinders their Coats from coming so near their Centre, as in the former Case, and so their Terms or Bounds of Contraction and Dilatation being near, they are moved from the Bound of their Contraction, unto the bound of their Dilatation, & strick the Touch sooner, and in less time, & so the space betwixt every Pulse is Commensurat by, and proportionat to the greater or lesser Contraction, a great Contraction making still a rare Pulse, and a lesser, a frequent one: And a clear resemblance of this is seen in Respiration, which in the Natural mode is more slow, and more Air received into the Lungs, and more expelled at every turn of Respiration, and then the Breast also Dilated and Contracted more, th●n in frequent and short Respiration, where less Air is received, and less expelled at every turn, and the Breast also less Dilated and Cnntracted: much like the former Phenomenon, in the Pump, where short & thick strokes poureth out less Water, than long and rare ones do. And in the Motion of the Blood, the Heart furnishes the quantity to the Arteries, in proportion only, as the Arteries are Emptied into the Veins, which in the Natural State, when the Circuit Motion is perfotmed Vegetly, may be a Dram or more, but when that Motion is Torpid and Loitering, and the Blood with difficulty passes from the Arteries into the Veins, the Heart at every Pulse conveys so much Blood into the Arteries only, as they by emptying themselves into the Veins have made room for, which may sometimes be very little; for in Agonizing or Expiring Persons, where the Pulse beats the Touch with the greatest frequency imaginable, it's because the Contraction is so little and consequently the blood squized out of the Arteries, so very little, that the Dilatation is again immediately felt on the Touch: and this is so frequent, that it is rather called a Tremulous Motion of the Arteries, than a distinct Pulse consisting of sensible Contraction and Dilatation, But according to the Hypothesis of the Grand Club, the Blood should then Circulat more rapidly, than which there can be no thing invented more Ridiculous.  
In Consequence of all, by the leave of that Learned Crew of Ignorant Black Doctors, it's very good Sense, and Reason both to say▪ that the frequenter the Pulse beats, the Circuit Motion of the Blood may not only be more slow, but also, by the multitude of the Phenomena before mentioned, solved by Dr. Brown, confirming this Hypothesis, is proven actually to be more slow▪ And also by the same Leave, it may not be impertinent to allege, since Nature does not accelerate Motion in Vain, That, that Frequency, beside what is illustrat before, is excited also, to overcome the slowness and resistance betwixt the Arteries and Veins, as ●● at more length held forth by Dr Brown in his Schedule. And how the Progress and Circulation of the blood is made thorough all he Meanders and Narrow wind, betwixt the Arteries and Veins, and that in so short a time as Nature requires it in the Natural State to Circle about (which according to Dr. Lower, is less than the 6th part of an hour) is very wonderful and difficult to conceive; and without very much Elevating and Abstracting our thoughts we can scarce have any Satisfaction of it: and therefore the Circulation of the blood was opposed by many, because they thought it impossible; but to supperadd to that stupenduous Motion, so inconceivable a Property, or accident, as an Augmentation or Increase, the mind must suffer strange Torture and Rack, to Comprehend it: but how easily may that Motion be conceived to be diminished.  
It was indeed the Inconceivableness of the Rapidity of the Sun's motion by the common Hypothesis, which made Copernicus fix the Sun and send the Earth a Rambling about it: By which all the Phenomena were alswel solved, and a more comprehensible and satisfying Notion of the Motion established to the boot: But these blacks make so much Noise with their Babble, of Rapidity, Violence, and Irritation, that certainly they will fright Phaetions Horses whom Copernicus had quietly stabled up, and send them a packing again about the World, and then they must fetch Vulcan to nail down the Earth to its fixed Centure again, for if the Sun and Earth come to shoulder others in their Orbs, they may give a terrible Jolt. And if the Rapidity of the Sun's motion be inconceiveable still let the Sun look to that, as well as the Blood.  
And with all such a Falls Notion as this of the Circulation of the Blood augmented does not stay here as being a mere Theoretical Error and of no further purport: But Alace it puts the Artiest in his practice upon the most dangerous measures, and Precipitates him into the most Fatal Errors, as impelling him to put Clogs and Barrs on that motion, wherein consists Life, often already too much Loittering and Fetterred. And is as pernicious as it would be Ridiculous to see these witty Doctors load a Horse that can scarce go Empty, for fear of his running away.  
Moreover, as Dr. Broun has observed in the Preface to his Book, this Circulation of the Blood did strangely lie in the dark for many Ages, and was long opposed, because it was thought impossible, (what then would these opposers have said to hear it's augmented now) and also it was opposed by others, because although it seemed to Illustrate the Theory of Medicine, yet it made no improvement in the practice thereof.  
But now by this Theory of Dr. Brouns, that noble discovery is not only Confirmed, and not everted (as these men through the Grossest mistake ignorantly assert) but also is delivered from that reproach of useless. For he clearly does evince this motion of the Blood Diminished, and its slowness depending upon the Grossness, to be the nearest Cause, if not of most diseases, yet of Continual Fevers: And further since he has shown by what Complication and Concatenation of other Causes, this nearest Cause by O●der or Congress is fomented: How many solid and fruitful Indications, altogether for merly lying in the Dark, may there be drawn from thence: Especially seeing we may be furnished with sufficient means to satisfy these Indications: And that either by Correcting; Intercepting, or Eradicating these Causes, being destinctly known. And so this Theory seems not only to be clear in itself, but also leads to the Practical Improvement of the Circulation of the Blood: And notwithstanding all the applause the Circulation of the Blood, has deservedly met with in the World, this Theory is as much preferable to it, as the best Practical Improvement is preferable to a mere Theoretical one, and in consequence every man's Demerit In relation to the Advancing and Opposing this most Plausible and Useful Theory of Dr. Brouns, must be Commensurable according to the value, it will really be found to be of.  
As for the rest of their Assertions, viz, That it's always a received Opinion that heat in Fevers is the effect of rapid motion of the Blood. Many of the best Authors, as Silvius, wiles Paracelsus and Helmont, etc. Attribute it to other causes, and albeit it had been a Commonly received Opinion, does that hinder but that it may be a Vulgar Error, and as they do not attaque, one of Dr. Broun's reasons against it, so they do not bring one for it: Then they make a digression into the cause of hea● in an Inflammation, In handling of which they first say, that the Blood is then Extravasated, and immediately they say, that the Ateries are distended therewith, pray let them reconcile these. And next they say, The quantity of Blood is the cause of heat in an Inflammation, than which there can be nothing more false, for in an, Anewrisma, which is a bag of Arterial, Blood with a continual Pulsation, and the part has far more Blood than an Inflammation or an● Aerisipelas, but far less heat: Yea none at all beyond the rest of the Skin.  
And in fine their whole Chat for reasoning I cannot call it is so pitiful and impertinent and nothing conclusive, that it appears they not only want the sense to lay down any plausible Hipothesis of their own, but that they never have Considered, Traced, nor Expended Dr. Broun's Conclusions: Far less can it be expected they will confute them: Which, albeit they had been false, could not have been distinctly done but in a Book at least three times as big as his, yet this curtaleing Club pretends to do it in less than one Leaf.  
As to what the Black Drs, allege there is nothing answered to these matters of Fact, wherewith Dr▪ Broun stands Branded in their Dialogue I●'s answered first, that the Black Mouthed Dis. Tongues are no Slander: Next it seems the heat of Black's Fury has drained his Common sense and Reason, for did not my former Letter tell him that their Dialogue contained nothing but Lies, Cavils and Calumnies: How come they now to ask what answer can be given to them. It seems these Black's has as little Skill in Common sense, as in Physic. For since these Slanders were denied, they should in the 2d, Pamphlet have brought their proof and witness, since Philander's denial is a● good as either Fool Sanders, or Fool Mathews Affirmation.  
That where the Black says, since Dr, Brown subjected his Book to the consideration of all Ingenuous and Faithful Physicians, now he has got the Sentiments of some of them little to his Satisfaction.  
First, who gives Black this Testimony but himself, and dare such Rogues Arrogate that name that dare not appear but in Masquerade. These Censurers for all their disguise will be found out by their scent to be no better than some piece of flat, Corum Bobus or viper ridden Fop, and some ill natured Brate, whom God and Nature has not made so Ridiculous as his Serpentine Viperish Humour has made Ignominious: And their Opinions of it is so much to Dr. Brown's satisfaction, that he would never have been well satisfied with his Book▪ if these silly and ill hewn pieces had not been mad at it. But ask what testimony Dr. B●. and Dr, B●e gave of the Book, to many famous witnesses, who yet can bea● Testimony of it, and whose Names ● cou●d easily mention; but I suppose these Physicians will minch yet nothing of what was their Sentiments of it. Not that I mention this to Establish any more Reputation to Dr, Brown's Book, than every reader shall be convinced is due to it, none having the power to Monopolise all men's Judgements, ●o great a Fool is Black to attempt it.  
As for these passages mentioned in their Dialogue and taken out of Dr, Brown's Schedule, and called either nonsense or Contradiction; It's answered Dr, Black has here proven very honest, and appears in his true Juggling Nature for any that will be at the pains to compare these passages with Dr, Brouns Book will find, that the most part of them are wrong 〈◊〉 down or Courtailled, all of them, the thread and Cohe-rence of the discourse br●ken and interrupted.  
And for that one sentence concerning acuteness, which is taxed of nonsense Dr. Brown has his end, when they break their Shines on it, for when he is speaking of acutness necessary in a Physician, he thought fit to wrap up the matter in a littly obscurity to be a Touchstone for a sufficient acumen, and so those Blocks having deservedly stumbled on it, is a clear concession they are Incapable to penetrate far greater mysteries, and withal there are such manifest Contradictions in their Dialogue, that he that runs may read (for indeed few will stay long to read it) This one I shall among many others name, first they represent Dr. Brown such a stranger to learning, that he has never piped beyond the Title pages of Books, and a little after, they represent him to have stolen his Book out of ten or twelve of the best Phisiological Authors in Physic.—. Dialogue page.  
As to what the Black Dr▪ says that his old method approved by thousands for many hundreds of years, should not be overturned to establish a new one with such manifest Contradiction. Now Black speaks like himself, a down right sitten on brate in Medicine that will allow no advance o● Improvement therein for hundreds of years, But, how ever long his method has been used, it has been surely very little successful, especially since I was any thing capable to make observation about things, and about three years ago as I remember there was a Physician in town Confessed that of 30 Patients he had that year of Fevers, only two of them recovered. And if Black deny this, there will be a list of their Names gotten and published, and at that same time fevers treated by the new method were all happily Cured.  
And though Fevers be not now so frequent as then, perhaps many of them being frighted away or Metamorphosed into other shapes, because of this Civil war among Physicians, yet it, ● very plain, that to diseases formerly called Fevers, our Physicians now give the n●m● of Surfeits, Colds, Rheum●tismes, Feverish fits, and I do not know what But what effect this is like to have ye may judge by this story, ane Apothecary came to a Dr, with a great complaint, saying their Trade would be all ruined, for their Patients and Friends, said they could take no thing the Physician had prescribed him, for they told the Physician mistook their Disease, because when they were sure it was a Fever he called it they do not know what.  
And indeed Philom all ordinary Fevers are als well known, and their Intention and remission, to any intelligent Patient or by slander as to a Physician: And that by their sensible symptoms, such as Heat, Drought, Pain of the Back, or Head, a Frequent pulse, and most part sudden invasion of the Disease, etc. Tho in some Fevers that are called Malignant, the ordinary symptoms are ●ither mild or absent, or bears no proportion, here the Physician has only the privilege to be Umpire and sole arbitrator: But where ever he usurps over People's senses and reason, all he gain● is to become himself ridiculous. Yea some Physicians lately in Town, professed Enemies to this Method, having cured Fevers by the same, but under the name of another Disease, when the Patient after he was recovered, heard what the Drs. called his Disease, he was almost frighted into the Fever again. thinking what a danger he had been in, when his Physician mistook his Disease, but at length the Apothicary came, and Cured him, by telling him the Knack how after this manner they concealed the new Cure of Fevers.  
Where the Black Dr. says, there are only 2 or 3. Young Physicians that follow, or favour that new Practic●●f Curing Fevers. It may be Answered, that there are more that favour it, than follow it, perchance hindered by a too servile Veneration to Elder Physicians, (that is more for fear of their ill than any hope of their good,) who perhaps may get that woe, like the Pharisees, for neither following it themselves, nor suffering others, and these that now own it, having done it, before ever they knew Dr. Brown, did equally manifest their accompl●sht Sagacity, in their being among the first that perceived, and descried Improvements, and their Ingenuity, that for no Base and By-ends, nor Slavish Veneration can be brought to pass over, or neglect them, and further these, though young in Years are capable to give good proof both by this, and their other Knowledge, that they are Mature in accomp●ishments, far beyond these Duarf shits, and sitten on Brats in Medicine, who have made no advancement therein, in Proportion to their Age; And that Dr. Brown's Enemies must be such a Fry, appears by their ill natured Papers, Dwarves and Elves being still the most Cursed Creatures in the World.  
The Black Dr. Moreover says, that it's not reasonable to believe all these Persons Instanced by me in my former Letter had Fevers, since Dr. Brown had the Impudence to call that a Fever, which two of the most eminent Physicians in Edinburgh said was none; what will he then say, where he is sole Physician.  
It's Answered, if by Eminent, they mean such as carry that respect to other Physicians, that the Co●klofts and Garrets do to Houses which a●e always worst furnished, or which (like the Weathercock above the Churches) serve only to tell how the Winds of fame Blow. It's easily granted, that such Eminencies may sta●e themselves in that Opposition to him, either ou● of Design, M●lice, or Ignorance.  
But since there is no Persons, or Case named, Dr. Brown is not concerned to do it: but if any other will do it. I hope there may, for the good of the World, be given such a clear Representation of the matter, as giv●ng every man his due, will lend such a blow to their Eminency, that b●●ying their honesty in its ruin, there will sca●ce be left them als much a● to swear by.  
And withal the Black Doctor says, he could, were it not for fear to give Offence to their Relations, name a Counter-list of these that have died under Dr. Brown's new method.  
Thanks to Dr. Black for his tenderness, after he has Glutted himself with all Malicious and vile Calumnies, and Reproaches, wherein Persons of Honour and good Credit were concerned and named. It seems now he has some remorse, and is in a fit of Tenderness, and stands at Offence, he that so frankly just now dealt about Injuries; and which is more a● Offence from a● unknown hand: when the Devil. (Oh, I mean the Fox) gins to preach, have a care of the Lambs: Black is not so desperately wicked, but he can put on a visage of Tenderness to serve a greater Design: but I think it were greater Tenderness, and more Dr. Black's Interest too, by such a Counter-list to have allayed the grief raised in these, who have had their Friends dead under his Methods, upon their seeing so much probability, they might have been Cu●ed, if they h●d been treated by Dr. Brown's new Method, and that at a far greater Cost, than such a Ridiculous and Chimerical Tenderness: but the Truth is, any such List being not only Impossible to be but there being fines, several that can be added to the List of these Cured, ●fter the New Method, they are forced to Palliate & smother the matter after this Ridiculous ●anner, and if it could be given, as the giving of it in this Case, could not easily offend any Man, so it would be a considerable Service to the World, and prove a mo●e Solid and Convincing Evidence for the Club, than all they have either said▪ or can say: there pretended Chimerical Tenderness then, is not only Cruelty to the whole World, but, which none but the highest degree of Fools can be guilty of, Cruelty to themselves: and therefore whether they be not in this pretence, either Liars, or Fools, or both, let the World Judge.  
It's here to be Considered, that although this Method of Curing Fevers has proven as yet so exceeding successful, that praise to the Author of all Gifts and Discoveries, Dr. Brown, and others has for several ye●rs practised it so successfully, that there has scarce any died under it: yet it cannot be thought Infallible, or ●o sure that it will never miscarry, for there may be such Complication of other Distempers with the Fever, that sometimes may evacuat the Effect: yet I think we may ●ay of it, as Donkers in the obs. 32, of his Book de febre Petechiali says of a Method very like this, which he used so very successfully, that scarce any died under it, he thinks it will agree to all Fevers, whether Epidemical or Malignant, which Testimony of his was most Learnedly Confuted by one of the Eminencies of the Club, who, upon hearing of it Magisterially said, he did not much regard the English Physicians, who were one thing ●o day, and another to Morrow: while in the mean time this Donkers is a German, and a Physician a● Cologne▪  
And albeit the Cardinal Point of this Method of Dr. sydenham's be Purging, yet its folly to think, but there is great Art, and Dexterity to be used in the management thereof, the Quantity, Quality, the Ti●e, and Repetition of the Purgative, which being used either within, or without the due bounds, and measure, proves alwayus useless or noxious:  
So that the Objection of the Grand Club, that every Apothecaries B●y knows to do it, is Frivolous and Ignorant: yea, and if ●uch a Method could be found out, that every Apothecary's Boy could use, it were a rich discovery: and therefore their Argument tells likewise, they are no ways of Generous or Public Spirits, but Mean, Base and selfish Persons.  
And now whilom, I think, I have run over the greatest part of their Learned mistaken Answer to my first Letter, (passing by the P●●le of disgorged Viper Spa●n and fopred, for rakeing therein might raise steem● very noxious to you) and sh●wn that they have brought nothing against Dr. Brown, but plain Cavils. Calumnies, and Foppries, and indeed that which they Object in the last place concerning his Education, savours rank of their Innate Ignorance: for they suppose no Man can be tolerably qualified, in Medicine, unless he be Bred at a foreign Vn versity. I pray you Club, what Universities were Hypocrates, Galen, Celsus, and many of the Ancients bred at: and do you not know, that several of the most accomplished Physicians in England ●ere never out of their own Country, such as Sydenham, wiles, etc. And that several of the most expert Lawyers in our own Nation studied at home. Pray, did you ever read Hypocrates his Lex, where he tells▪ that there are Nomine multi, re verò pauci medici: and he makes the chief condition, and means of Institution, to be Industry and Education from a Child in the Practice. And indeed Dr. Brown being Educat in that Study, and Practice from his Childhood near 30 Years time, there is no body will doubt, but this coterie paribus might he a●s good a mean for his acomplishment i● a practice suitable to the genius of the Country, as any breeding at a foreign university, for a short time would be▪  
A. to what they object in further persuance of their 〈◊〉 concerning Dr. Brown's receiving Degrees at Aberdeen  
It's Answered, first, the receiving Degrees, in Medicine in any place, is very far from being a Testimony, or proof, of any Man's accomplishment: and is always given abroad periculo peten●●s, to the greatest Dunces that w●l pay for it: And to prove this, can there be greater Blocks in the World than the Black Club (as their Papers do bear Witness) who are all Foreign Graduate Doctors: and has learned no thing abroad, but to Parat it to the Vulgar, after their return, in the Gibberish of Justitutions, D●ss●ctions, Courses of Chemistry, Colleges of Medicine they learned abroad, and yet they never conned the A, B, C. of true and solid Knowledge.  
N●xt it's the greatest Impertinency Imaginable to disparage Dr. Brown with receiving his Degrees at Aberdeen● where there is a Professor of Medicine, for, besides that several of the considerable Members of the College of Physicians at London have received their Degrees there, can any Scots man doubt but the dignities or Honours flowing from the Soveraign●●y of our own Nation, are much preferable to these Conferred by a Foreign, as is clear in Knight ●●od, N●bility, and who ever d●iparaged a Doctor of Divinity, because he was Graduate within the Nation.  
But with all (a●d ●● seem the Black, do not know so much, albeit they be most of them Members of this College) the Sovereignity of this Nation ha● by the Patent given to the College of Physicians at Edinburgh, annexed a privilege to these Graduate within the Country beyond any Graduate abroad; and that is, they are ipso facto free, and licentiat in the College, without any Trial or Composition; to all which these Graduate abroad art liable, and what is this, but to hire us to be wise, and to encourage domestic projects of Virtue, and Improvement, which these Blacks, as Enemies to Mankind in general, and to our National Improvement in Particular attempt to discourage and as the State has most justly given encouragement to Domestic Graduation; So it were in my Opinion, the great happiness of the Nation, because, greatly tending to the Improvement of Medicine here, that Convenient Encouragement were given for the study, and Institution of Medicine within the Kingdom also; for thereby there would not only be saved a great deal of Money that is Yearly spent in the Breeding of Physicians abroad; but also Students would be thereby better acomplisht and Educat in the Practice suitable to the Complexion of the Nation, and Temper of the Climate; and the Diseases, and Cures proper to the Genius of the Country would become sooner familiar to them: for young Physicians bred abroad, return often very raw in Medicine, and always quite strangers to the Genuine Practice of this Country.  
And so Philom. every thinking Man may easily Collect, that the only proper expedient to redeem the Nation from these Inconveniencies, and to promote the Advantages , were to Erect within the Kingdom a Profession of Medicine, with Hospitals for the Sick, subservient thereto.  
And as Dr. Brown has done all in him lay to raise Domestic Improvement and Virtue by his Graduation at home, so he has given a farther evidence of a public Temper, by his being very Zealous to project that other National benefit of Domestic Improvement, the study in Medicine also at home: for he did not only prudently choice such a Patron to his Book, who (himself, and his Son having a considerabl● post in the State) seemed qualified to lend the Project a Lift: and to whom, as Patron he might have more freedom, ●nd access ●o represent, or negotiate it: but also he gave in to his Lo. a scheme of the Project in Writ, mentioning withal the retrival of (as Dr. Brown judges) Ane apposi●● Fo●d to sustain the Charge thereof; and as his very generous Maecenas at that time was pleased to look upon the Overture, as not altogether contemptible: so it's not to be doubted, but after more mature deliberation, his Lo● will in that affair discharge the Office of a true Patriot of his Country. And this Passage I mention Philomath, not only as directly falling in my way, but more especially, because Dr. Brwn's Enemies have been so Impudent, as to traduce his Temper, and designs, and Mis. represent him strangely, also in these; But now ●oeal to all the World, if ever any Physician in the Nation, (not to speak of that Degenerous and Malicious Crew his Enemies,) gave such Testimony of Public-spiritedness, as this one passage (not to mention any more) clearly Imports he has done.  
To return to our Purpose Philom. and to touch the Definition of a Fever, which the Black Club desiderat in Dr. Brown's Book: They essay to give none themselves, as being like Ignorant bunglers, far better in throwing down other men's Work than building themselves; but how nonlen●efi●al a doubt is this: just as one that had read both the Black Doctor's pamphlets should ask for a Description of the Black D●ctor, for as he is therein drawn to the Life, an Ignorant F●●. and malicious Br●te: So almost all Dr. 〈◊〉 〈◊〉 Book is spent in explaining the Nature and, 〈◊〉 of Fevers, whose variety being Indefi●te, according to the various Disposition of the Impellent and Principle of the Motion, the various Disposition of the movable Matter, whither Solid or Fluid, and of the Passages throw which the Motion is made: that variety, I say, cannot allow us to have a clear Idea of them, be brought under such narrow bounds as a Definition: but is rather the Subject matter of a Scheme: which Dr. Brown has essayed to draw in his Book.  
〈◊〉 〈◊〉 Sign of a Fever commonly called Pathognomick be the frequency of the Pulse. yet in some that are unquestionably Fevers, the Pulse is not frequent, which I suspect may be solved thus. Albeit the Blood circulat as slowly in these as it does where the Pulse is more frequent▪ and consequently the Contraction and Dilatation of the Arteries, are but of the same Extent, as when the Pulse is frequent, yet because the Velocity and swiftness of the Contraction, and Dilatotion is also lesed; and they become Languishing and slow; there may be als much time spent in that lesser Contraction and Dilatation, and in Consequence, the Pulse beat a● seldom on the Touch, as it does in health, where it moves with its due velocity, and so here the Velocity of the Contraction and Dilatation seems lesed, as well as the extent, of them, In Consequence, I think this Description of a Fever not Improper.  
A Fever is an universal difficult Circulation of the blood and Humours, throw their grossness, and obstruction of the Passages, having several Phenomena, as immediate effects, and others mediate from the efforts of the Impellent or first mover for redintegration of their motion, which is excited by the Impressions these Immediate effects make on the Impellent, as frequency of the Pulse and other orgasmes.  
A Fever has no Pathognomick Sign omni, it has a Pathe gnomick Sign soli, that's a frequent Pulse: and where that is wanting, the present state of the Bloods Circulation is Collected from a Syndrome, or Concourse of Causes 〈◊〉 to produce that grossness of the Blood; the Cause of defficult Circulation; and from the presence of the usual Concomitants of such a Disposition, and from the other Phenomena that as Irrdiations and Beams are darted from such a Disposition: all which are more largely held forth by Dr. Brown in his Book.  
Now if any would be satisfied to have a description of Dr, Blacks Nature from his Phenomena, if Horace who certainly was no ways prejudicated his Description of the man may be trusted, take it as he gives it Lib; 1, Saty, 4, Line, 81.  
— Absentemqui rodit amicum,  
Qui non defendit Alio Culpante: solutos  
Qui captat risus hominum Famamque dicacis  
Fingere qui non visa potest: Commissa tacere  
Qui nequit: hic niger est, hunc tu Romane Caveto  
Englished because perhaps the Blacks understand Latin als little as they do Greek.  
Who honest men reviles behind their Backs,  
And ne'er defends them, he dots on senselels Knacks  
A public Railer; loves to break a Jest;  
And to be merry-andro at a Feast.  
Tells all he hears, and adds a great deal more  
Which ne'er were seen or e'er heard before,  
My Country men beware of Dr, Black  
A Brutish crew, an Ignorant Devilish pack,  
There snarling Barking tells they're Black mouthed Dogs,  
Their Cavilling quirking tells they're Ignorant Rogues.  
who ever desires a short and easy way, that the meanest Capacity may know a Black by; take this.  
Would you a Black clearly discern  
If Dr, Brown but meet him,  
Black looks on him so cruel stern  
As truly he would eat him.  
And to confirms all take also Hipocrates the most wise of all Physicians his Sentiments, in his Book De Art, Where he says whosoever endeavours with Artifice of Indiscreet and Dishonest words to disgrace and abuse the Discoveries and Inventions of others, neither Endeavours to amend them, but traduces them before the Unlearned, He se●ms incapable to be esteemed prudent, and betrays his Malitions' Nature and Ignorance.  
But lest I be thought to leave this Malice ridden Crew in Wrath, (their number as well as their Condition deserveing pity) I think it better to take a charitable farewell, and to leave them with a wholesome and sound advice, providing they be capable to follow it; and it's a prescription of which if they can but get the right Ingredients, and make right up, it will quickly Cure their Distempers and miseries especially their Ignorance.  
Take of Limpid and smartest Menstruum of Natural Acuteness, as much as ye can get the more the better 
* That which cannot very easily penetrate the preluminaries of Dr, Brouns Schedule, especially that paragraph in the first Section concerning Acuteness, is quite dull and naught. * Not the volal●ie for that is naught, this Salt must be made after the manner prescrived in the first Sects of Dr, Brown's Schedule. * These must be gathered and prepared after the manner in the 2d, Sect, of Dr, Brown's Schedule.  Impregnat this Menstruum with a sufficient quantity of the fixed salt of true sense of the Physicians duty and obligation lying on him to accomplishment * then add unto this Menstruum, thus impregnat als much as will be proportionat to the quantity of the Menstruum of serious Industry constant Labour and inquisitive search, * then seal the vessel with the Hermetical Seal of the Physician's sequestration from other Employs or Diversions▪ And set it in the Balneo of Speculation, let the Balneum be still keeped warm with the Constant heat of serious and Intent Application of the mind till the Menstruum Extract a Tincture that looks Brown, if it look Black all is spoilled, it will be of a Corrosive Poisonous Nature: then Filter the Tincture throw the Filter of diligent Observation and so ye will have an Excellent Elixir Philosophorum called Medicinal Prudence, which ye may Aromatize pro renata when ye come to use it with some Guts or Grains of Personal Prudence to make it more Palatable and Passing.  
The virtues of the Elixir Prudentioe medicoe.  
It Cures all Reeling meg●●m▪ Giddiness in Physicians, all Deliriums, and Rave, yea Madness itself, if it be not natural, or from bad Conformation of the Parts.  
It's excellent to clear their sight, helping all favits of the eyes, especially Suffusions; yea, it Cures Infallibly that most dangerous and Epidemical Disease in Physicians, the Gutta Serena, where the Orgains seem Intainted and Sound to the Spectators, yet there is nothing but Darkness and Blindness within.  
It's good in all diseases from Venom and Viper spaun, and Malignant Humours, especially against their Parox●●●sms and Fermentations, when being stirsed up, they cause excesive belshing out of poisonous Eructations, not withstanding whereof, they are in hazard to burst the Body of the Patient, and obliges him still to be Clasped in Ir●n-Bands and Fetters, like a Malefactor.  
It's good against all Stupidity and Fopishness in phisicans, cutting all Snotty viscuous humours, purge▪ out all Fopred that dulls their Brains.  
It's good for all Rickityness, Dwarsing and Sitting on in Physicians, making them advance more in on year than they would otherwise do in Twenty, or Thirty.  
It's good for overflowing of the Gall and Heartburning, for all Choleric Diseases, the Black and Yellow Jaundice, which make all things appear wrong to th●m.  
It's good also for the Apetitus Caninus in Physicians, which makes them d●●or● six times a●s much Employment as they are able to digest or dispatch, which is a disease ordinarily incident to these that are Duarft, and sitten one in Medicine.  
I should have also given them a cure for their Malice and wickedness: but that seems to be a Devil that cannot be cast out without Fasting and Prayer, therefore I must leave it to the Churchmen.   

The Publishers Advertisement to the Reader.  
Whereas the Black Doctor says he will Answer Dr. Brown no more which if he do not, and be als good as his Word, I'll swear that it's the first time that a Skittish Jade after being so touched in the Quick, did not both Fling and F— t. too.  
If Dr, Black's back be Galled with whipping and Smart I have an extraordinary Anodine Balsam of Consolation to give him and its this.  Desine Flere niger nondum pro viribus egit. 
Dr. Brown,  
solace thyself, weep not Poor Sorry Black;  
For Brown has not yet opened half his Pack.
