they call Stuypiens doth proceed from the said more Acid Pancreatick Juyce who hath accurately attended to those Invasions and the Symptomes accompanying them and the way of Cure For besides that Acidity which doth very often breath through the Mouth they suffer the Gripings of the Belly the Milk may likewise be perceived to be concreted both upwards and downwards the Excrements of the belly are more Green and give forth a sharp Odour they are also cured by the tempering of Acidity as for Example with Aqua Feniculi Aqua Lilliorū Conuallium Spir. Salis Armoniaci c. The same more Acid Pancratick Juyce carryed to the blood through the Lactean Veines will give it a greater Consistency whence the Blood less Rarifying will produce a lesser Pulse From which Vice highly exceeding we judge a Syncope sometimes to be produced which is not a little confirmed by that Example which Lazarus Riverius relates in Lib. VIII Fol. 358. of his Practice concerning that Syncope which P. Salius as he reports Lib. De Afect Practic Cap. IV. observed in a Girle of 14 Years of Age Who after a dayes suffering of Heaviness of the Head Vertigo and grievous Anxieties the day following suddainly dyed Afterwards her Body being diffected the whole blood in the great Artery and the Vena Cava appeared to be Concreted and so changed that it might intirely be drawn out from the Vein and Artery even as a Sword out of its Scabbard Concerning which thing if any doubt either by ours or others Examples let him take an acid Liquor and pour it by degrees into the Vein of any Living Dog and he shall not only observe the Blood therein to be so Coagulated and Concreted that the greater bloody Vessels may be transversly cut without the Effusion of the blood but also when the acid Liquor shall come in a notable Quantity to the right Ventricle of the Heart that it will presently extinguish and kill the Dog Also no man will deny that Convulsions for the most part proceed from an Internal Cause from the Acrimony of Humours irritating the Nerves and causing by a greater Influx of the animal Spirits into the Muscles Involuntary and also Violent Motions But when there is a two fold Acrimony of Humours viz. Acid and Salt some perhaps may doubt which of these do most frequently produce those Convulsive Motions But for as much as we can observe they rather proceed from an acid Acrimony than a Salt because we see that Aromatick Medicaments and those abounding with a Volatile Salt do very much conduce to their Cure which would never come to pass if they drew their Original from a Saline Acrimony Besides they are accompanyed with such Symptomes which are wont to be the Concomitants of Diseases arising from an acid Acrimony Yea the Effects of Acids are allowed to be far more powerful as is to be seen in Helmont De Lithiasi Cap. 9. Pag. 725. § 71. where he relates that he saw a Chymist which after he had been much Conversant about making of Aqua Regia he fell into the Palpitation of the Heart Convulsions and many other Incredible Dolours by reason of the acid Exhalations which mingled themselves with his Blood From the same Acidity we stedfastly believe That the Strangury is very often produced seeing that together with other Students we have sometimes found the Urines of such as have laboured under the Strangury in the Hospital of Leyden to be Acid and also seen the same Persons cured with such Medicines as temper Acidity The which if you are minded to try saith Helmont De Pleura Furente § 14. Whether or no the Strangury may not proceed from Acidity mix some Drops at least of sharp Wine with the Vrine lately sent forth without pain and inject it again by a Syringe and you shall find to your Pain that what I say is true Also that from the more acid Pancreatick Juyce Ulcers do sometimes break forth in the Skin corroding the same as also producing very great paines they will not deny who following the Opinions of the Antients determine them to arise from the Atra-Bilis seeing that the Atra-Bilis of the Antients as we have above Demonstrated hath its Original from the more acid Pancreatick Juyce We are like-wise plainly perswaded that the more acid Pancreatick Juyce especially if it hath any Austerity conjoyned with it produceth a greater astringency of the Belly For if the Bile by its Acrimony irritating the Guts as is granted may excite the Flux of the Belly why may not that which is contrary to such a Bile produce a contrary Effect Notwithstanding if the belly be bound by a Viscid Matter then we think likewise that a Flux may happen from the sharper Pancreatick Juyce as it hath a power of inciding and attenuating the Viscid Pituity From which it is manifest that the Pancreatick Juyce according to the Diversity of Humours concurring with it doth very often produce a diverse and contrary Effect which thing we would have well noted lest we should seem to contradict our self in explicating the Effects of this juyce As yet we think even as we seem to have already said that the Atra and Eruginous Bile is excited from the more acid Pancreatick Juyce and a certain sharp Bile concurring and consequently all Diseases which Authors deduce from them and therefore they are not cured by other Medicaments than those which are fit to correct the more acid Pancreatick Juyce Which as it is Consonant with Reason so it will not appear Incredible to those who will consider the things above spoken by us with a more attentive Mind But perhaps some will say after what manner doth the Pancreatick Juyce produce the Atra-Bilis seeing that we have ascribed the Whitishness of the Chyle after the Effervescency in the thin Gut to the acidity of the Pancreatick Juyce To which we answer That Acids according to the Diversity of the matter where-with they are mixed do also produce a divers Colour for example pour an acid Spirit to common Sulphur dissolved in a Lixivium and its red Colour will be changed into white Antimony Calcind with Nitre or Chalk being boyl'd in Fountain-Water and any acid thing being affused to its clear Colature will presently acquire a Saffron Colour A clear Infusion of Galls mixed with the Solution of Vitriol maketh Ink to which if you add the acid Spirit of Vitriol that Ink will lose all its blackness and become clear like to Fountain-Water The Blew Tincture of Violets being mixed with Oyle of Vitriol will wax into a Purple The Wood Acanthus brought from Brasile being infused in Common Water doth freely yeild a red Tincture which put to Distilled Vinegar acquires a Colour like to White-Wine A Knife after it hath cut a Pomecitron in the Middle unless it be wiped and cleansed from the Soure Juyce of the Citron in a short time will be reduced to a nigrous Colour And why from the same acidity too much exalted
For very many Diseases do every day occur in our Practice wherein that Feaver either proceedeth is concomitant or doth follow So that sometimes it requireth an intire Method of Curation for it self Which seeing it is so we think our Cogitations and Experiments not to be ingrateful to the Curious Searchers of Nature especially if we hold their minds not long in suspence by rehearsing the Sentenses and Opinions of many Authors as they ordinarily have done who have gone before us in the same kind of Study or retain those things by shewing an intire Series of Questions relating more to Curiosity than to the necessity of the thing to be known but we shall presently expound in a few words as much as is possible those things which we judge concerning this matter Seeing that Aristotle hath rightly said Lib. 2. Physic Cap. 13. That there can be a sure Knowledge of nothing the Cause or Original whereof is not known We contrary to the Common Order shall endeavour to pursue the Nature of Intermitting Feavers by searching out their Signes and Causes Seeing that all Physitians which have hither-to written of Intermitting Feavers cry out that their Pathognomick Signe is a more Frequent and Preternatural Pulse to know the Nature altogether of Intermitting Feavers by searching into the Causes of the Pulse we judge with the never sufficiently praised Fran. de le Boe-Sylvius that the Cause of a more Preternatural Pulse is either first the too much and Permanent Rare-faction of the Blood arising from a more Potent Fire breaking forth from the Effervescency of both Bloods Or Secondly because of any sharpness being at one time Acid at another Lixivious another while brinishly Salt driven through the Veines with the Blood to the Heart and Internally gnawing the Parenchyma of the Heart Or Thirdly something halituously Flatulent and like-wise carried with the Blood to the Heart or excited by the Effervescency in the Heart and increasing the Explication of the Ventricles of the Heart Or Fourthly something sharp or hard either in the Peri-cardium or else-where existing and externally gnawing or pricking the Heart These few things being premised there is none but may see that the cause of continuall Feavers is continually carryed to the Heart but the cause of Intermittents by Intervals It is not our purpose here to speak of Continual Feavers those that are desirous of searching out and knowing of the Nature of those we recommend them to the Practice of Dr. Sylvius where amongst other things accurately delivered they may find the exact Description of those Feavers Chap. 29. Pag. 407. And we in the mean-time being about to deliver the Description of Intermitting Feavers shall say That such a Focus or Minera of Intermitting Feavers is required which is apt to transmit the cause of a more frequent and Preternatural Pulse by Intervals to the Heart Sundry men have sought this Minera in diverse parts of the Body some have immagined they have found it in the Mass of Blood which to some others seemed less true to whom the Continual Motion of the Blood was known because the Circulation of the Blood is performed once twice or four times a day For the most accurate Dr. Lower in his Treatife of the Heart Fol. 156. proveth That the Blood of a Man well disposed circulateth through the Heart in the space of one Hour thirty times But being granted which in no wise may be denyed that the Mass of Blood of the whole body at least sometimes in a Day doth flow back to the Heart part of which if evilly affected as often as it transiteth the Heart would produce a Fit of a Feaver and so from the Blood naturally following neither a Tertian or a Quartan Feaver may be deduced unless they say that the Blood doth absolve this Tragedy being preternaturally detained in any part of the body which like-wise doth not alike appear to those to whom it is known how easily the Volatile Spirits exhale by the Detention of the blood and the remaining Particles of the blood being made more sharp do suddenly excite mutually among themselves a Heat and Inflamation of the Part to which if an Aposteme be subjoyned that will affect the Blood passing through its Circuits continually and not by Intervals Whence if a Feaver follows it ought not to be called an Intermitting but a Continuall Feaver If they say that the obstruction is not expected to the generation of intermitting Feavers but to furnish the phlegme which is of that nature that daily the yellow Bile w ch every third day and the Atra-bile which every fourth day may produce a certain ebullition many of a higher ingenuity may ask first whether or no those humours such as they are described in the Schools can be Demonstrated to be in the mass of Blood seeing it is evident by what is already said the Atrabilis derives its original from the yellow Bile and more acid pancreatick Juyce Secondly how doth that seem probable that a humour more cold tenatious and unapt for motion as phlegme daily and a hot humour being more fluid and being fit for motion as yellow Choler should every other day onely excite a feaverish Ebullition in the Blood Thirdly how intermitting Feavers may be changed from quotidians into tertrans quartans and the contrary Fourthly to what humours they can ascribe Quintans sextans or those which have more seldome periods of which Fernelius lib. 4. cap. 14. if they determine that each Feavour draws its Original from a certain peculiar Humour But they which have held the minera of intermitting Feavers to be latent in some part of the Body have most of them sought it in the Abdomen for nauceousness loathing of Food Torments Colds Horrors Rigors and other preludiums of the fits conspicuous to none but such as are more attentively disposed do shew the Abdomen to be evilly habited A vomiting excited either by Nature or Art and very often presently asswageing the fierceness of the fits sheweth the principal ways or passages thereof to be evilly habited The Cure it self of the Abdomen also in the beginning of the access declareth the same according to Fernelius de sede intermittentium lib. 4. cap. 10. for Fomentations applied to the Hypocondriaes procure a remission of horror rigor and other Symptomes But what part of the Abdomen in these Feavers is evilly affected hath wearied the brains of many for so confusedly have they sought their minera that nothing of certainty can be concluded from their writings or opinions for some have sought it in the meseraick Veines some in the Branches of the vena porta between the Liver and the Spleen some in other Vessels yea also in the great Colon the duplicature of the Omentum which is under the ventricle and in innumerable other things have they determined the focus of intermitting Feavours whose Clouds of falsity in these our more happy times the sun of Truth hath so discussed and dissipated that they want not our improvement
of any other thing with the blood then volatile Salts But on the contrary if you mingle any acid Spirit with the Blood Dictum Factum the Blood will be more or less Coagulated according as that Spirit shall be more or less Acid as for example if to try the Experiment we take Oyle of Vitriol Oyle of Sulphur per Campanum Aqua Fortis Aqua Regia c. Besides that the Blood will presently be Coagulated by them it also acquires a Ches-Nut Colour But if we take the Dulcid Spirit of Salt Juice of Lammons Distilled Vinegar or the like whose acid Spirit is more Temperate the Blood will only acquire the Consistency of a grosser Syrup with its red Colour remaining unhurt From whence it is evident the use of Acids may preserve men from the Plague not as according to the Opinion of many Authors that they cut and attenuate but as they preserve the natural Consistency of the Blood and do hinder its being infected with a more sharp Volatile Salt which we together with the Air suck into our Bodies For this cause the most Famous Dr. Sylvius who likewise hath Constituted the Venom of the Plague in a more sharp Volatile Salt when some Years since in the great Plague at Amsterdam which he fore-saw he took a Crust of Bread imbrued with white-Wine-Vinegar in which Mary-Golds had likewise been steeped by which Alexipharmack he so well preserved himself that he never was infected with the Pestilential Venome But when through too much hast he omitted the said Alexipharmack as soon as he entred into an infected House he was infected with a pain in the Head from which at other times he was free Which things being rightly considered every one may see that the Pestilent Venome is not indued with any force of Coagulating as the most Learned Willis hath stated it in his Treatise of Feavers C. 13. But seeing that Dr. Dela-Font hath sufficiently cleared this to all Opposers in his Discourse concerning the Pestilent Venome Chap. VIII We shall not spend any more time either to the Reader or our selves but wave the further Disquisition of those things because it is besides our purpose in this Treatise accurately to describe the Pestilence Wherefore we will leave the rest to a further Occasion seeing it is time that we return to the Incommodities flowing from the more Acid Pancreatick Juyce The Pancreatick Juyce being more sharp is the cause first of every Internal Cold being first of all felt in the Region of the Loyns and afterwards dispersed into the whole Body as for the most part we observe in the beginning of the Fits of Agues or Intermitting Feavers Secondly Of all Cutting paines as well in the Hypocondria's and whole Belly as in other parts of the Body Thirdly Of all manifest paines in the Belly from whence the Sick is sometimes tormented after a wonderful manner Wherefore we deduce all the black and aeruginous Bile from the same more Acid Pancreatick Juyce Because sometimes being put into a Pewter Chamber Pot or Brass Bason they Corrode the same and send forth a sharp Savour and also excite a manifest Effervescency which every man who hath saluted but the threshold of Chymistry knows cannot happen from any thing but Acids From whence they may be compelled to confess their Errour who affirm That all black Choler proceeding from Vomitting or Dejection of the Belly comes from the Follicles of the Gall or the Spleen All these things are not a little confirmed by the following Experiment sometimes made by us in a Dog in the Section of whom being alive having opened the Duodenum we found a greenish Liquor among the black such as the Antients have depicted to us for Atrabilis that we might pursue a more Intimate cognition thereof we examined diligently all the wayes through which any thing might be transfer'd to that Intestine and seeing that besides the Bilar Duct the Pancreatick and the Ventrile there was no way perceptible to the sight through which any notable Quantity of Humors might be afforded to the Intestines we judge therefore that in one of those the matter thereof must be obscured Wherefore we examined all those wayes in the first whereof we found the Bile naturally Constituted that waxing Yellow from a Green In the second we found the Pancreatick Juyce most limpid like to Distilled Water In the third we found the Aliments half crude having the Colour of White Ashes Seeing therefore that neither the Liver nor the Pancreas nor also the Stomach carryed that Atrabilis to the Intestine we began to suspect whether that Atrabilis might not emerge by the Union of two or three of those Humours being mingled together by course Concerning which thing that we might attain to a greater Certainty we affused Spirit of Vitriol to the Bile drawn forth from its Vesicle and placed it in the heat of the Sun from whence there was commonly excited from the Black a Greenish Liquor such as we first found in the Duodenum Hence we concluded the said Humour called Atrabilis not to flow from this or that part but to be generated in the Duodenum Namely as the Natural Colour of the Bile hath been transmitted into Black and Green by the Concourse of the more Acid Pancreatick Juyce Seeing that the Pancreatick Juyce by the ordinary Law of Nature may continually be mingled with the Bile and the Intestinal Pituity we will a little propose the same as joyn'd with those Humours If it chanceth that the more sluggish Pancreatick Juyce bounds with a sharper Bile and the Intestinal Pituity rightly Constituted the strength of the Pancreatick Juyce in that Concourse will be altogether infringed and the Exhalations which are excited by the Effervescency of those Humours will ascend not so much with Acid as Lixivious Particles which when they reach to the Stomach by infringing its Fermentation they will hinder the Concoction of the Aliment and destroy the Appetite but if it happen that those Exhalations ascend to the Jaws there amongst other Incommodities they will induce a Dryness of the Mouth especially if they infect the Spittle with their Salsitude But if they proceed further through the Milky Veines to the Heart from whence with the blood they may pass through the other parts of the body they will also produce a Heat in those as at first in the Intestines and there more troublesome where those Exhalations are most sharp If a more sharp Pancreatick Juyce concurreth with a sharper Bile there will presently be a mighty Effervescency excited in the Duodenum whereby the Intestines are sometimes so distended that they threaten a Ruption which thing we have very often observed whilst we applyed our selves to our Study in Leyden whilst we mixed together divers Liquors sit for Fermentation in two little Vessels in part of the Intestine intercepted by Ligatures even as D. Schuyl hath expressed it Fig. B. in his Treatise De veteri Medicina wherefore we judge in the first instant
in Ulcers the Cyrurgions Probe may not be stained with a certain Blackness as we have very often observed and such Ulcers be happily cured by Temperating of the acidity as Helmont admonisheth De Blase humano § 53. we leave to the judgment of others It may here suffice for us to have proved that from one and the same acid permixed with diverse things one while a White another a Black another a Yellow another a Purple and so moreover other Colours may arise He which desireth to excite many Colours in the Solution of Minerals and Vegitables endued with no Colour let him go to that most curious Treatise which D. Willis hath written concerning Fermentation where pag. 88. Edit Ang. he may find very many Mutations of Colours not unprofitable and being about to assigne the Reason thereof he saith in the following page If the reason of this Phaeno-mena be enquired it ought altogether to be deduced from those minute particles within the pores of every contained Liquor which according to the scituation and position being after a divers manner altered by the Infusion of another Liquor do diversly transmit the beams of the light and manifoldly break or reflect it and so cause the divers appearances of Colours c. Having now unfolded the Diseases risen from the more acid Pancreatick Juyce we seem in our selves to hear some in short to ask the Question from whence the acid Humour in the body may proceed if we do not use any acid things To which we answer that we can in no wise want those things which abound with an acidity For there is an acidity in the air which appeareth if the Caput Mortuum of Vitriol be exposed to the air which from the same eliciteth a new acidity Also that the air is full of Nitrous particles Gassendus Entius Digbaeus and others which professedly or otherwise ingeniously treat of this Matter have proved But no man is ignorant that Nitre containeth in it self an acidity There is also an acidity inherent in Aliments For in Kitchings if flesh or other Aliments begin to corrupt their Broth doth wax sower yea we have collected an acid Spirit in quantity sufficiently large from the sweetest of Condiments to wit Sugar by chymical Art There is also an acidity inherent in Drink for Beer or Ale as also Wine being left to themselves without the addition of any other thing do wax Soure From whence it is no wonder as Hippocrates witnesseth Lib. De Vet. Med. Text. 24 that there should be an Acidity in Men. But it being granted that there is an acid Humour in our Bodies some one more desirous of Truth may ask How it comes to pass that it doth not only corrode the parts of our Bodies but also Copper and Tinn as we have shewed above To this we shall also answer That the Fermentations continually happening in our Bodies is sufficicient for this thing For we daily see that by their help many things are very sharp which before were sweet or at least Temperate VVhether now this may happen by the Dissipation of the animal Spirits or by reason of any other inward Cause we leave to the Judgment of others Likewise Experience testifies that Men feeding upon a cold Diet do sometimes for the same Reason and Cause fall into burning Feavers We have also deservedly ascribed the Uterine Suffocation or Mother-fits so called to the Pancreatick juyce divers ways vitiated but especially the Austere The following Observation seems to give us no small light into the Truth of this Matter which our Friend Elsnerus in the Year 1667. sent to us from Paris to Andegave We opened saith he a Maid extinguished by the Suffocation of the Womb in whose dead body we found nothing at all to which death might be ascribed but the blood coagulated in the Ventricles of the Heart beyond the order of Nature Which too much coagulation of the blood may not be deduced from any other cause than from an acid Juyce as we have sufficiently proved But the reason why we judge that this Effect is not produced by the Pancreatick Juyce being simply acid is that all women which have a sharp Pancreatick Juyce are not affected with that Disease And therefore we do the more easily believe that there is an austerity or harsh Sowerness present with it because we have known almost the like Disease excited from the Pancreatick Juyce being austere in a certain Bitch as also in a Famous Man the truth of which the following Testimony freely exhibiteth to us done in the Year 1663. as it was communicated to me by the most expert Dr. Sylvius I tested the Pancreatick Juyce and found it first as it were Saltish but afterward the Relish being some-what changed it seemed then to be Sub-acid with a light Austerity There was such a Stink produced in my Mouth that two of my Acquaintance which were with us admonished me concerning it The Stink was like to that which riseth from Muddy and strinking Water My Mouth and Jaws were not only exsiccated or dried but also so constringed that I seemed to be suffoccated which like thing I suffer by a Disease familiar to me And all these things vanished not suddainly but remained and endured for a while till they left me by Degrees and of their own Accord The Bitch's Juyce was brought to the Famous Dr. Sylvius and exhibited to his Tast in our presence From this and the like Observations it seemeth not absurd to assert That Men may some-time be affected with a like Hysterick Suffocation especially when its nearest Cause happens not from the VVomb but from the small Gut in which by reason of the Vitious Effervescency of concurring Humours excited Exhalations and austere Flatulencies are stirred up which as often as they arise through the Oesephagus or Gullet and come to the Arteria-Asperia or Wind-Pipe they so constringe those parts that the Sick think themselves to be in the peril of Strangulation or Choaking That divers Species of the Hypocondriack Affection may be produced by the said Pancreatick juyce divers ways vitiated the Books of Practical Physitians do testifie and the symptoms confirme But that we stay no longer upon the more acid and austere Pancreatick juyce and the effects from them arising we think fit to deduce at least one effect from the said juyce more Salt imagine a serous Diarrhaea which by its saline Acrimony produceth a more violent and more frequent peristaltick Motion of the Gutts These things being rightly considered we doubt not but that by a diligent tract of time by the Observation of those who happen to be conversant about the Sick many effects will be made more manifest And if there be more of Art in knowing than in curing Diseases who sees not that this Pancreatick juyce being altogether known the cure of many Diseases may be performed more easily more speedily and more profitably First of all in this Treatise we have described the Diseases taking their Original from a
Therefore least we consume our own and the Readers time by writing more things obvious as well in the Books of the Ancients as in the Moderns we shall willingly pass them by Seeing that the cause of all intermitting Feavours seemes to us to be contained in the pancreas alone The reason of this Opinion is this that having considered the parts of the whole Body of man which by intervals only may transmit the Cause of these Feavers to the heart none can be found in the whole body to which not only the Focus of intermitting Feavers but also the causes of all their symptomes may be imputed besides the Pancreas But some perhaps may say that heat thirst ulcers breaking forth in the lips of the Feaverish bitter Vomitings Cholerick Excrements and other symtomes wont to accompany tertain Feavers do declare the bile to be primarily offended wherefore the Cause of all intermitting Feavers ought not to be ascribed to the pancreas alone But truly this objection will fall of its own accord those things being known which we shall speak of in the following Discourse concerning the Reasons of divers Symptomes for we know that in tertians the bile is very often predominant but it is to be noted that its abundance doth not cause an intermitting Feaver because that is perceived after it hath excited a vitious Effervesency by intervals with the pancreatick Juice in which if the bile gets Dominion the signs thereof even now declared do somtimes manifest themselves but because this Effervescency proceeds from the pancreatick Juice preternaturally disposed that Feaver is not ascribed to the Bile but to the Pancreatick Juyce as by the Sequel shall more plainly appear We judge the cause of Intermitting Feavers to be an Obstruction made in one or more of the Lateral Ducts because of Pituity carryed thither in too large a quantity and there detained VVhich thing seems to us to happen for the following Reason to wit For as much as the Pituity of the thin Guts especially that sticking to the sides lest they should be hurt by the abounding Humours being in too great a quantity by reason of the immoderate Exercises of the Body and perhaps by an over-much use of hot Aliments or by some Error committed in the six Non-Naturals is dissolved and with other Humours carryed to the Heart by the Milky Veines From whence by the Order of Circulation this Phlegmatick Matter together with the rest of the Blood is driven to the Pancreas and being separated in its Glandules with the Pancreatick Juyce it enters the Lateral Ducts of the Pancreas in which either by the External Cold or of that Bowel it concreteth and is Coagulated by which reason it obstructeth either one or more of the Laterall Ducts VVe think the accesses of intermitting Feavers ought to be ascribed to the Pancreatick Juyce stagnant in one or more of the Lateral Ducts by reason of an Obstruction and one while sooner another while later preparing a way for it self through the Obstructing Phlegme by its Acrimony increased and not only causing a Vitious Effervescency in the small Gut but being every way carryed especially to the Heart produceth a more frequent and preternatural Pulse Which that it may more clearly appear we shall spend a little time in the unfolding thereof That Coagulation which we have mentioned to happen in the Pancreatick Juyce we have some-time observed in a Dog whose Juyce we endeavoured to collect in the Winter time which by the cold of the Ambient Air was so thickned that only a little would flow forth and of a gross Consistency untill the Dog being placed before the Fire between two Pillows began to grow hot from whence the Pancreatick Juyce did flow more Fluid and more Copiously We have observed that the Coagulation of the Pancreatick Juyce hath excited Obstructions in the Lateral Ducts of the Pancreas as in the Year 1663 with the Famous Dr. Sylvius in a certain Woman labouring under an intermitting Feaver into whose Ductus Pancreaticus after Death we injected by a Syringe a very Volatile blewish Liquor which out of the great Duct into which it was cast did penetrate into most of the Lateral Ducts whilst in a few although more near to the Intestinal great Duct by reason of an Obstruction it was stopped From whence by the said Colour the Substance of the Pancreas it self was tinged in one place and not in another The Pancreatick Juyce being stagnant in one or more of the Lateral Ducts by reason of an Obstruction by its delay becometh more sharp and at length perforating the Obstructing Phlegme prepareth it self a passage through the Obstruction into the common or middle Duct until all the detained Juyce being effused the Phlegme as yet adhereing to the sides of the Duct grows together again and by its mutual Reunion renews the Obstruction Whence at length the Pancreatick Juyce is Collected for the following Fit which again by its delay being made more sharp doth again perforate the Obstructing Pituity and produceth a new Paroxysme which Fits return alwayes at the same time as often as the Pituity causing the Obstruction doth occur in the same Quantity and Viscidity with the Pancreatick Juyce of the same Acidity and Acrimony The Pancreatick Juyce is made more sharp by Stagnation in as much as the Animal Spirits do not so straightly embrace it but leave it obstructing Hence therefore by the dissipated Spirits wont to attemper it there redounds a greater Acidity of the Pancreatick Juyce Would you have a Simillitude We will grant it New Ale included in Hogsheads Whether or no by a certain delay it doth not lose its Sweetness Consider that all Wine turns to Vinegar the Spirits being dissipated also that Vinegar it self by delay is made more sharp For every heat dissipating the Animal Spirits causeth every sharp thing to be more sharp So that it ought to seem strange to none if we say that the Pancreatick Juyce by stagnation deserteth its genuine Disposition and passeth into a more acid Acrimony But the Pancreatick Juyce being made more sharp by stagnation and effused into the thin Gut with the Flegmme and Bile stirs up a vitious Effervescency and indeed by reason of such a Pancreatick Juyce stretchings yawnings and horrors are produced and every-where a sence of Cold especially in the Region of the Loynes in which the Fit begins Neither is that first called a Feaver which either the Pancreatick Juyce it self vitiously Effervescing in the small Gut or at least Exhalations from thence arising and at length carryed to the right Ventricle of the Heart and after a certain manner irritating it to a more frequent Contraction of it self But we judge that the Pancreatick Juyce by its acid Acrimony performs this thing although nothing hinders but that something of a Saline Acrimony arising from the Bile may concur because we daily observe that Exhalations do ascend in the Effervescency between Acids and Salts which being moved to the Nose by its
collecting it by sensible Experiment the surest of Guides to convince those who oppugne and resolve the Doubting which he hath largely shewn 3. Because the Anatomical Disquisition of the Pancreas and its Juyce is omitted by Sylvius in the first part of his Praxis as not pertinent to his present Scope which omission this Book supplies and to which the said Sylvius in a manner refers his Readers So that he which deliberately reads this Book will be thereby highly inducted to the Vnderstanding of the Doctrines and Notions of the most Learned Sylvius concerning the Pancreatick Juyce throughout his whole Writings as they relate to diverse Diseases and Affections of the Body of Man The second Commodity I shall propound is That this Book doth most Indubitably contain the certain Causes of all Agues or Intermitting Feavers with their true and effectual Rules of Curation It is a wonder to see the many Books which have been written concerning Agues and Feavers perhaps as many as there are Old Womens Medicines for the cure thereof and the great Diversity of Opinions concerning their Causes and differences so that for a man exercised with a tedious Ague to call a Councel of Physitians to his Assistance usually received no more Relief than a Criminal Person doth by the Verdict of a Jury which delivers him from Prison either to Death or Banishment Which hath formerly enrolled this Disease in the Catalogue of those which were wont to be termed Opprobrium Medicorum the Reproach of Physitians Neither in my Judgment is it greatly to be wondered at that Physitians were wont to have no better success in the Cure of this Disease seeing they were involved in so many Vncertainties about the Seat and Cause thereof some assigning the Seat to be in the Blood in general others in some perticular Parts of the Vessels where the Blood happened to be stagnant others in the Meseraick Veines others in the Guts and perticularly in the Colon and several other Conceits as if they went about to gain the Knowledge of the true Seat Arithmetically by the rule of false Position Then again as to the Causes and Reasons of Differences whilst they ascribed them to the Four Humours viz. Blood Choler Phlegme and Melancholy and their different Degrees of Mistion and Putre-Faction they ran upon such Rocks as constantly ship-wracked the Barks of their Opinions For still as they endeavoured to solve one difficulty that would arise they caused the Rise of another But this Author's Hypothesis being so free from all Intricacies and Difficulties renders it agreeable to Truth I have yet further to say in the behalf of its Certainty that is the Consequence of Curation which although every single Cure of a Disease doth not indeed declare the Administrator of the Medicine to have a certain Intelligence of the Cause of the Disease yet when a Distemper shall be certainly cured at divers times in different Persons and with different Medicaments alwayes from the Notions Doctrines and Considerations of the same Cause that surely is a certain Argument that the Cause is known And this I my self have oft-times done even to Admiration by removing Ague-Fits in a few dayes space and never yet failing of the Cure of any kind of Ague whether Quotidian Tertian or Quartan with their Compounds and am yet by God's blessing ready at any time to undertake the cure of the worst Ague-Fits that are which Aquisition I acknowledge I owe to this Author I am able also to perform the same in those deplorable Fits commonly called The Fits of the Mother I have instanced this not out of boasting but to shew the certainty and excellency of the Doctrine of the Pancreatick Juyce and to excite the Reader to a serious Contemplation and Observation thereof There is yet a Third Vtillity of this Book which is That it refutes several Errours in Physick and Anatomy many of which in times past have been received for certain Truths and some of them perhaps yet remaining the Principle whereof relate to the Pancreas or Sweet-Bread and to the Nervous Juyce concerning which I shall say no more but commit you to the things themselves as they shall occur by reading I have nothing more to say but to beg the Readers kind Acceptance and withall to mind him of the Difficulty of things of this Nature especially when an Author writes in such a style as de Graaf hath done that if he meet with any Errours committed by me I hope he will the more easily pass them by as not being Intentional and I presume not Essentiall If I find this be kindly accepted it will encourage me to serve my Country with some-what of my own more at large I do expect to be censured and snarled at by some for as Erasmus saith Nihil morosius Hominum Judiciis there is nothing more peevish than Mens Judgments I shall easily dispense with it being of a peacable Spirit And as I have professed to do this for a Publick Good so I also declare that I have been void of Prejudice therein to all Mens Persons and Interests being only desirous of the Propogagation of all Laudable Science whilest I am Christ Pack From my House at the Signe of the Globe and Chymical-Furnaces in the Postern near Moor-Gate Feb. 2d 1675 6.

second Opinion is attributed to Baccius and Folius both which sharply maintained that the Chylus passeth from the Intestines to the Liver and Spleen through the Ductus Pancreaticus The contrary of which is as clear as the Meridian Sun Seeing that nothing is received from the Gutts into this Ductus but only the Juyce sent forth by it self to the Intestines The third Opinion is ascribed to Johan Veslingius because in his Systeme of Anatomy chap. 4. he thus speaketh of the Pancreas The use of this Ductus is not obscure for seeing it hath acertain Juyce not much unlike to the Bile it is manifest that such an Excrement is separated from the Chylus by a further Concoction and being conveyed into this Vessel is thence emitted into the Duodenum Asellius Riolanus and others favour this Opinion but Experience contradicts it and manifestly sheweth that the Humour contained in the Pancreas is never really in it self bitter and therefore in no wise to be compared with the Bile If at any time it happens that the Probe being put into this Ductus be yellow every one will easily believe that this is not occasioned by the Humour contained in the Pancreas but from the Bile as well flowing from the Ductus Cysticus as the Hepaticus immediately into the Intestine especially if he consider that the Stylus is spotted by the Bile before it passeth from the Intestine to the Ductus Pancreaticus and again that it passeth through the Bile whilst it is drawn out For the Ductus Pancreaticus and the Ductus Biliarius in Men perforate the Intestine in the same place And although the most famous D. Van. Horne in a Bilious Diarhaea saw that Vessel full of Choler we say it was Preternatural in as much as the Bile which Copiously adhered to the end of the Ductus as is wont to happen in a Diarhaea was thrown into the Cavity thereof by the Agitation of that dead Body Also that the excrement of the further Elaboration or Concoction of the Chylus is not sent into this passage is manifest in regard the same is witnessed by Occular Inspection In some Animals that Glandulous Body doth not at all touch the Milky Vessels and in others it only passeth over and in no wise enters their Substance as also because they are easily separated from the Pancreas without the Effusion of any Chyle as we have formerly demonstrated in Dogs Cats and other Animals Therefore we do not see upon what ground they might maintain the further Concoction of the Chylus to be celebrated in it unless they following the Opinion of Asellius would take this Glandulous body for the Middle Glandule of the Mefentery into which the Venae Lacteae are altogether immersed The fourth Opinion is of Bartholinus as is manifestly apparent from his Anatomy Chap. 13. De Pancreate where he thinks the Bile to be purged Naturally by its Ductus and will have it to be the Bilar-Vesicle or Gall-Bladder of the Spleen so that the same use which the other affords to the Liver he believes that this affords to the Spleen Which Opinion by the leave of so great a man Anatomy in our Judgment seems to confute Seeing the Ductus Pancreaticus passeth not to the Spleen neither are there any other Vessels which do convey any thing from the Spleen to it For there are found only two kinds of Vessels which carry any thing back from the Spleen viz. The Veines and Lymphatick Vessels But the Veines carry back the Blood to the Liver and the Complication of the Lymphaticks carrying from the Spleen do not in like manner go to the Pancreas but to the great Receptacle of the Chyle so that nothing can be discharged out of the Spleen to the Pancreas as our tryal in France hath sufficiently manifested for their sakes who judging this to be the best Opinion of most Authors rejected ours We tyed a Dog upon a Table as is Demonstrated by the first Figure of the third Table and when we had made a little Hole in the left Hypocondrium with our two fore-Fingers we pull'd out the Spleen whose Bloody Vessels we tyed with two or three several Ligatures and afterwards we cut the same in sunder between the Spleen and the Bonds and when we had quite taken away the Spleen we drew together the Lips of the Wound with small threds in three or four several places whereby this Dog in ashort time being well cured was returned to us at which we did not at all wonder because we once had a Bitch which brought forth three or four Puppies after the Extirpation of her Spleen and two Mouths after the loss of the Spleen in the same Dog we collected a notable quantity of the Pancreatick Juice which the Professors of Andegave the Doctors of Vtrecht D. Haverloo and D. de Maets judged to be acidly Salt which being true none as we think free from Prejudice will maintain that the Succus Pancreaticus proceeds from the Spleen Also it is worthy to be noted That those Dogs did no less greedily desire or better digest their Food after the Extirpation of the Spleen than before from whence we receding from the Common Opinion judge that no Fermentitious Matter or Humour is sent from the Spleen to the Stomach The Fifth Opinion is attributed to the most Famous Lindanus seeing that in his Medic-Physiol c. 5. Art 5. pag. 114. he saith When I consider what appertains to the Vse besides the structure of the Pancreas how many Diseases Practise takes notiee of in it I cannot doubt but that the thicker and more useless Purgations of the Blood are thrown out into it by the Ordinary Law of Nature so as they may be corrected by the Spleen and also by an Extraordinary all the Melancholy which either an Intemperate Diet or Disease hath bred The Ductus it self gives us cause to believe That they are both carryed to the Intestines and Curation teacheth the same by the Medicines often required And this Opinion seems also to us to be contrary to the Truth seeing that the Pancreatick Juice as often as it hath been truly collected by us alwayes appeared Limpid like Wine But what we shall say concerning the Excrementitious Humour will sufficiently appear by the following Article and also by those things which shall be spoken of presently after The Sixth Opinion is manifest enough from Wharton's Treatise of the Glandules Chap. XIII whilst he writes Therefore I think that this Glandule as likewise all others do minister to the Nerves and that it receives some of the Superfluities of the Nerves of the Sixth Paire with the little Branches of the Spinal Marrow in the greater folding of the Vnitings and by its own Proper Vessel carries it to the Intestines But seeing that the Nerves are designed to carry Animal Spirits we do not understand upon what ground the industrious Anatomist will hold that the Excrementitious humour is carryed through them and wherefore he will affirm that it is
he declares that Aqua Mulsa or Hydromel or if to cleanse more powerfully with the Decoction or bitter Juice before-mentioned of Worm-Wood Centaury or Lupines that may be effected adding Honey or Gall which above all other things as hath been often said doth make those things which are Viscous Fluid c. But the Succus Pancreaticus being pregnant with a Subacid Spirit as appeareth by the Precedent Reasons and Experiments doth in like manner augment the Viscidity of the Aliments by the Solution of their Fluidity the which being so as it is more than sufficiently known we will not delay time by further proofs concerning the Manner wherby Acids in the thin Gut do return to a Liquid and Fluxile Motion or other-wise to an Ineâ—t and Pituitous Viscidity we shall only say that in our Judgement it so happeneth for as much as by the Tenuity and Sharpness of the Parts stirred up by the Effervescency the Phlegme is thereby as with Swords incided and attenuated into very Minute Parts That which attaineth a Whitish Colour then observable in the more Fluid part of the Aliments we think it deducible from the Acidity of the Pancreatick Juice because we may note that many other things abounding with a Lixivious Salt and Oyle do wax White upon the affusion of Acids So that Vinegar or Sharp Wine being poured upon common Sulpher dissolved with any Lixivium and grown Red that Reddish Colour is so changed that it is made almost like to Milk Wherefore also it is called by the Chymists Lac Sulphuris The same is apparent in the Resinious Extracts of Vegitables as also in Spirit of Hart's Horne or Soot being Replete with much Volatile Salt with which an Acid Spirit being mixed acquires a Milky Colour All those things being rightly considered we judge Secondly That the Effervescency in the thin Gut is exceeding necessary for the right Separation of the profitable Parts from the unprofitable But perhaps some who are altogether wedded to Antiquity admitting nothing which to them is Novel because they have read or understood nothing in the Antients concerning this our expected Secretion by Fermentation will not think that such a preparation is required to separate the profitable parts of the Aliment from the unprofitable but that the alteration which is performed in the Stomach is sufficient to this purpose in which if any thing be wanting it may be Consummated by the Peristaltick Motion of the Guts by the help whereof it s more Fluid parts are thrust forward into the Milky Veines the Foeces with the remaining thicker and lesser profitable parts passing away by the Channel of the Intestines To the which we deny not but that something is contributed to this matter both by the said Fermentation and the Peristaltick Motion of the Guts nevertheless we do not think that any Physitian unless a Slave to the Antients amongst all those things which are daily observed in the dissecting of Brute Animals and Medical Practiss or at least-wise may be observed will reject this cause proposed by us If first of all he diligently consider that in the Coeliack Flux the Aliments sometimes viscid like a Pultiss and every where alike and sometimes mixed with a whitish Liquor are purged out But this Diversity of Colour happens by a Contingent or Non-contingent Secretion of profitable parts from the unprofitable by the said Effervescency which who can but in vain Attribute to expression alone Yet we deny not that by the Fermentation of Aliments alone rightly performed in the Ventricle something Fluid may Spontaneously pass away from the rest of the Aliments more Pultatious nevertheless that is but little if it be compared with the large quantity of noble Chyle which is continually strained through the Venae-lacteae or also from thence swimming up in the Caeliack Flux so that then the more watery part of the Chyle freely going forth by the Compression of the Bowels alone is more without Effervescency than the other which is more white or as we may say more Milky In that Spontaneous Separation of the parts wont to happen through Fermentation the Spirituous indeed first go forth with the Watery necessary for the Reparation of the Animal spirits We have an example in the Fermentation of Plants other things abounding with a Volatile Spirit in which the Spirituous Particles alwayes expanded and endeavouring to flee through the Pores of the Stomach and Guts being loosed from their Fetters rush through the Pores From whence we are fully perswaded that after the Assumption of the most Spirituous Aliments a suddain strength is found in men and although it be Inconspicuous to our Bodily Eyes that the Spirits by the same reason are diffused through the Pores of the Body nevertheless after a manner we understand it with the Eyes of our Mind whilst we see a Stupendious Vertue in some Medicaments externally applyed The same thing is often observed by Anatomists when after the Incision of the Peritonaeum they receive the Foetid Flatulencies passing through the Tunicles of the Guts to the Nostrils But because the Spirituous and Volatile parts are not sufficient to sustain Life but Moreover Acid Oleous and Salt parts are also required therefore there is need of a new Alteration of things assumed that those parts by a decent Copiousness might be separated from the Superfluous and Unprofitable Which alteration we call Effervescency and by help of which we judge with our sometimes Famous Professor Francis de le Boe-Sylvius from whose Lectures as well publick as private we do not deny to have drawn many Fundamentals of this Doctrine that Secretion to be accomplished We do not only judge by that Effervescency mediateing the more Subtile and Fluid parts of Aliments but also the Pituity by the help thereof dissolved in the thin Gut part of which is carryed together with the better Portion of the Bile and Succus Pancreaticus through the Vermiculous crust of the Intestines into the Milky Veines from hence to the Cisterne or Common Receptacle of the Chyle and Lympha placed in the Region of the Loynes under the Appendices of the Diaphragma and from thence ascends through the Chyliferus or more rightly the Lymphatick Ductus Thoracicus because it continually carryeth the Lympha and the Chyle only by Intervals to the Subclavian or left Jugular Veine that from thence it may descend with the Blood through the Superiour Trunck of the Vena Cava descending into the right Eare of the Heart and the right Ventricle thereof And in the right Ear and right Ventricle of the Heart it is confused both with the ascending and descending Blood and also impregnated with the Pancreatick Juice the Bile Phlegme and Lympha from whence it acquires a requisite Consistency of Blood This confirms what we have said That any thing acid Coagulates all Fatness and Oyle But because on the other side the aforesaid humours have in themselves a force of attempering we need not fear too great a Consistency of the Blood
Pancreatick Juyce being driven to the Intestines in a lesser quantity will not sufficiently free the Gutts from the superfluous Humidity in them and so will occasion many Obstructions as the Learned R. Lower who judgeth this juyce to be ordained by Nature to cleanse the Chyle he writeth in his Treatise of the Heart Chap. 5. page 215. that by the defect thereof he hath observed Obstructions of the Venae Lacteae in these very words It seems to me most true that that great Glandule namely the Pancreas is seated in that place and that Ductus to be opened into the Intestines that the Lympha for so he calleth the Pancreatick Juyce being there separated may be mixed with the descending Chyle whereby it may more readily enter and more expeditely pass through the narrow Channel of the Lactean Veins and indeed the Chyle in the Milkey Vessels either because of its crascitie or for want of potulent Liquor which ought to be for its Vehicle may sometimes be apt to be stagnant and so concrete and by the same reason to stop and altogether fill up those Vessels as in a Dog whose Pancreas was obdurated I once observed Neither also will it sufficiently promote the Natural and due Separation of the Chyle from the Excrements and that especially if the Aliments be more dry or of a more difficult Fermentation Hence necessarily follows a diminished Nutrition of the whole body as also a universal Languishing so that such may rather be said to draw Life than to live But the Pancreatick Juice being separated in a larger quantity and brought to the Intestines will as it were pare off not only their superfluous Pituity but also that necessary part which should defend them from Injuries like a Curry-Comb and besides it will separate more than it ought from the assumed Aliments so that sometimes the unprofitable and excrementitious parts together with the profitable may be conveyed to the Mass of Blood sometimes only the profitable Parts but in a larger quantity than they should may be carryed by the same wayes From whence if here we say a Pethora will happen and thence a Cacochymy Who can overthrow our Assertions More-over we think that the Lancionations in the left Hypocondria first molested by courses do proceed from too great a quantity of the Bile and Pancreatick Juyce separated from the Blood by a more vehement Motion of the Body and the stirring up a greater Effervescency For it is most certain that Running or any other vehement Exercise of the Body doth accelerate the Motion of the Blood through the whole Body which seeing it is the cause of the Separation of these or other Humours then it is also necessary that those Humours be deposited into the Guts in a greater plenty which being separated in a Natural Quantity and Quality if as we have already proved they may excite a natural and friendly Effervescency to Nature may not the contrary happen when they are otherwise disposed by exciting an Effervescency greater and troublesome to Nature After a wonderful manner doth that place confirm this our Opinion in which those paines are perceived by course and very ordinarily though unjustly are ascribed to the Spleen because the Spleen is not in that place where those pains do in us excite a Molestation but hath its seat more down-wards because in that place those paines do manifest themselves in the Anteriour part of the Hypocondria where the thin Gut M emerging under the Mesentery N doth lye by the Peritonaeum as is to be seen in the first Table where we have Delineated to the Life the Scituation of that Intestine The inequal separation of the Succus Pancreaticus and propulsion thereof to the Intestines produceth various Mutations in the Guts and else-where concerning the suddain Happening of which no man will ever assigne a fit Reason who will not give heed to those things Hence we think to be deduced the suddain Deliquiums of the Wind sometimes advening erratick Feavers intermitious of Pulses c. The Pancreatick Juice being more fluid will more dilute the Pituity of the Guts and perhaps sometimes occasion the Flux of the Belly especially if it be conjoyned with a Salsitude by whose acrimony the Guts are provoked to their Contraction and unless that Flux of the Belly follow the Peristaltick Motion of the Guts it will necessarily express a greater Quantity of Chyle into the Venae Lacteae from whence the same incommodities will arise which we have deduced from the Pancreatick Juyce separated in too large a Quantity The more Viscid Pancreatick Juice concreting by the least external Cold will occasion Obstructions as also intermitting Feavers and likewise astringe the Belly Concerning the sensible Qualities and first of the Rellish there is sometimes produced a Pancreatick juyce less acid from whence there is neither a due Effervescency in the Duodenum and therefore not a necessary Separation of the profitable parts from the unprofitable nor a desired Consistency bestowed on the Blood and therefore they in whom such Blood is have been less able to resist Pestilential Venom than those in whom by the laudable Acidity of their Pancreatick Juice have also a more Laudable and greater Consistency of their Blood Hence the reason is also clear Why Melancholly Men are less afflicted with the Plague than those who are endued with a Bilious blood For we think that no man may be infected with the Plague so long as the Natural consistency of his blood is preserved We assert this the more freely because we see the blood in all persons infected with the Plague to be altered and obtain a far more fluid consistency So that if sometimes by chance Negligence Ignorance or any other urging Cause as for example too great a Plethory spitting of blood bringing a present danger to Life let a Vein be opened the blood flowing out although refrigerated nevertheless is in no wise coagulated neither can it acquire a due consistency even as sometimes is wont to happen to the animal Spirits being loosed from their Fetters and dissipated from the acidity existing in the blood wherefore also such a blood by divers Practitioners is called putrid We commonly say because it may so happen that the whole Mass of blood not as yet equally infected the laudible part of the blood in the cutting of a Vein may only flow out the blood remaining in the body being depraved the which thing Practitioners daily observe to happen in Venae-Section we do not only think with other Practitioners that the blood remains fluid without the bodies of those who are infected with the Plague but do also affirm the like fluidity in the bodies of those extinguished by the Pest as we have learned by Experience which perhaps may seem strange to those who know not the Nature of volatile Salts but not so to us who have very often mingled it with the blood and the blood always remained fluid the which cannot be certainly expected from the commixture
