invictives that are able to quite choak 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 Aeconomie of Mans Bodie and these so clearly solved thereby and made so neaâ—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 mans 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 Aeconomie 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 â—conomie such as the contraction and delatation of the Pupil of the Eye and in Actions from Irritation commonly so cled An Hypothesis that quadrats with the Composition of the Blood which is made up of many little Gâ—â—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 wayes being apt to produce viscosity and grosness in the Blood and Humors An Hypothesis that 's founded in the Consequences of that great tho Insensible Evacuation of Perspiration lâ—sed 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 occuring 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 shewed how the Benefit from volatile and fixed Salts and testaceous Concrets exceedingly â—avours this Hypothesis and also how the benefit of Cupings Leiches and Frictions confirm it A Hypothesis which has cleared the hurt of the meer 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 hâ—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 Iâ— consequential and False Assertions concluding with all nothing against the Hypothesis they may as well think Arthurs Seat will be overturned bya few Mol-hills casten up therein by the poor blind Moles and this I think will fall in nobodies 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 minuts better than on such Trash for no better Epithet can I give what they have said against Dr. Browns Theory as you shall easily perâ—eive 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 Fiâ—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 al 's absurd as to say that a Miln-wheel hath an Inate Faculty to move about which idonâ—e by the falling of the Water upon it 2. They say next All Parts when delated do suffer ever violence from the Humors and what els they contain does the Dilatation of the Brain or Breast come from violence I pray of what yea does the heart it self suffer violence from the Blood These Men are so Giddy themselves that they labour to turn all the Moderat and Benigne Motions in Nature making Life into reeling violent and Preter-natural ones they are so much in Love with Jarring that they dream of nothing but Force and Discord 3. They say That the ventriâ—les of the heart are of the same substance with the Inner coates of the Arteries and Veins which is scarce sence and that they are sensible of Irritation that the Dilatation of the Heart the weight the distention through eâ—â—ervescence 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 Rediculous 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 Stomack which is not seâ—t out till after Digestion but then by no Irritation As also the Effervescence of the Blood either in a Natural or preter-natural state is a stale 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 eâ—er these acute Drs. discover the same in the Blood if all the World must believe against their Sences with these subtile Doctors pray let them â—sher in Transubstantiation next for they have broken the great But that kept it out 4ly They say This Irritation makes the Heart contract it self without respect to a final Cause This is a clear Repugnancy for all Irritations in the Parts when they are are Preter-natural Motions from Preter-natural Causes and are raised to rid the Partes offended of the Irritating Marter 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 â—ne end quite distinct from that Implyed 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 Sysiphus Labour maliciouâ— Nature sends in another Dash or Squirt to vex it and this being perpetuaâ— puts the Heart in a Continual Chaff at the poor Blood which comes no sooner into the Heart but as a troublesome Guest is immediatly thrown out into the Arteries Irritating them likewise which presently sends it a packing into the Veins which having al 's little Kindness for it are at Continual toil to send it back again to the Heart Where it gets al 's 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 Viâ—â—lnce there two principles of Natural Motion I pray you Witty Club what violents the Heart to Dilatation and Iâ—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 slipt so fouly 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 slâ—w is great non-sense O brutish Ignorance for first this last Assertion is no wayes consequentiall to the former tho they bring it in Consequence thereof and next any that considers the matter will find the last Assertion a plain falshood for to say in a Fâ—veâ— the Circuit Motions of the Blood is mâ—re slow and yet the Pulse more frequent is alâ— good Sense as to say that the stroakes of a Pump may be doubled and yet the Water come out more slowly than at other times it does by single stroaks And this Phenomenon in the Pump is obvious to the Senses with its Cause for if either the Liquor Pumpeâ— be more viscuous or if the Top-hole be not clear the frequent agitation of the Pump will pour out less Liquor than the moderat working thereof when the Liquor is sufficiently tenuious and thin and the Top-hole clear As also the short and thick stroaks of a Pump pours out less Water then long and rare stroaks do even so the Pulse of the Heart and Arteries altho more than usual frequent may convey less Blood into the Veins when the Blood it self 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 Circumâ—erence 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 then 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 Aire received into the Lungs and more expelled at every turn of Respiration and then the Breast also Dilated and Contracted more thâ—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 Loâ—tering and the Blood with difficulty passes from the Arteries into the Veins the Heart at every Pulse conveyes 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 alledge since Nature does not accelerat 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 â—â— at more length held forth by Dr Brown in his Schâ—dule And how the Progress and Circulation of the blood is made thorow all he Meanders and Narrow windings 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 therfore the Circulation of the blood was opposed by many because they thought it impossible but to supperadd to that stupenduous Motion so inconceivable a Propertie 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 â—â—minished It was indeed the Inconceivableness of the Rapidity of the Suns 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 als-wel solved and a more comprehensible and satisfieing Notion of the Motion established to the boot But these blacks make so much Noise with their Bable of Rapidity Violence and Irritation that certâ—inly 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 Suns motion be inconceiveable still let the Sun look to that as well as the Blood And with all such a Fals Notion as this of the Circulation of the Blood augmented does not stay heer as being a meer 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 Rediculous 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 altho it seemed to Illustrate the Theorie of Medecine yet it made no improvement in the practice thereof But now by this Theorie of Dr. Brouns that noble discoverie is not only Confirmed and not everted as these men throgh 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 Grosness to be the nearest Cause if not of most diseases yet of Continual Fevers And further since he has showen by what Complication and Concatenation of other Causes this nearest Cause by Oâ—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 seing we may be furnished with sufficient means to satisfie these Indications And that either by Correcting Intercepting or Eradicating these Causes being destinctly known And so this Theorie seemes not only to be clear in it self 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 Theorie is as much preferable to it as the best Practical Improvement is preferable to a meer Theoretical one and in consequence every mans Demerit In relation to the Advancing and Opposing this most Plausible and Vseful Theorie 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 alwayes a received Opinion that heat in Fevers is the effect of rapid motion of the Blood Many of the best Authors as Silvius Willes Paracelsus and Helmont c. 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 heaâ— in an Inflammation In handling of which they first say that the Blood is then Extravasated and immediatly 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 Inflamation then 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 then an Inflammation or anâ— 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 sence 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 Leafe As to what the Black Drs alledge there is nothing answered to these matters of Fact wherewith Dr Broun stands Branded in their Dialogue Iâ—'s answered first that the Black Mouth'd Dis. Tongues are no Slander Next it seems the heat of Black 's Furie has drained his Common sense and Reason for did not my former Letter tell him that their Dialogue contained nothing but Lies Cavells 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 sence as in Physick For since these Slanders were denyed they should in the 2d Pâ—mphlet have brought their proof and witness since Philander's denyal is aâ— good as either Fool Sanders or Fool Mathews Affirmation That where the Black sayes since Dr Brown subjected his Book to
