X. Both Aristotelians and Galenists affirm that the child at first lives the life of a plant but from hence the Aristotelian concluds that the heart is the first members begot in us because it is answerable to the root in plants which is first generated but the Galenist infers that the liver must be the first member because the child living the life of a plant hath no other faculty but nutritive which is the faculty of the plant the seat whereof is in the liver But here I side with Aristotle because the liver is no more the seat of nutriment then the heart And because the heart is as the root but it is by the root the plant lives and is nourished And if the liver be the seat of nutriment because of the blood thereof I should rather say the heart is this seat because we finde blood there out of the veins as in a cistern but in the liver there is no other Blood then what is in the veins Neither can the liver be the originall of the nutritive power because there is the sense of indigence or want for so the stomack should rather be this originall because there is the most exquisit sense of want XI The liver cannot be generated without heat and spirits But the seat of heat and spirits is the heart therefore this must be first If any will say that the heat of the matrix is sufficient I deny it for that heat is onely conservative not generative it hardeneth and consolidateth the outward parts but doth not produce the inward XII Aristotle will have the right ventricle of the Heart the nobler Galen the left but I subscribe to Aristotle because I finde that the right Ventricle liveth longer then the left 2. That the Pulse in the right side of him that is dying is more valid then in the left side 3. The right ventricle leans upon the lungs as upon a Cushion or supporter Nature shewing as it were a greater care of this then of the other 4. The right parts are nimbler and stronger then the left because they are hotter 5. Though the spirits receive their completion in the left ventricle yet they are prepared and fitted in the right and therefore there needs not so great a heat in the left ventricle as the Galenists speak of for a moderate heat will suffice to perfect that which is already begun 6. The left ventricle is but a servant to the right in finishing that work which was begun by the right and distributing it into the body being finished XIII The Aristotelians make the vital and nutritive faculty the same the Galenists make them distinct but the Peripateticks reason prevails with me which is this That where there are distinct faculties there must be distinct operations because the faculty is for the operation But there are no distinct operations of the vital faculty from that of the nutritve for accretion diminution and generation are actions of the vital or nutritive Sense and motion are actions of the animal faculties 2. Life is the presence of the soul in the body this presence consists in action this action is nutrition for when this action fails life fails because the chief and first action of the living creature is to preserve it self which cannot be without nutrition seeing nutrition is not without tact in the sensitive creature but when tact faileth animality must needs fail XIV The Aristotelians make heat the efficient cause of the hearts publick motion Others will have the soul Others the vegetive faculty but Aristotle is in the right for the soul works by its faculties and these by heat so that heat is the immediate cause of this motion and the souls instrument yet not such an instrument as worketh nothing but by the force of the principal agent for the heat worketh by its own natural force though it be directed and regulated by the soul the heat then of the heart rarifying the blood into vapors which require more room dilate the heart but by expelling some of these vapors into the arteries and receiving also some cold air by the lungs the heart is contracted this is called Systole the other Diastole And as heat is the efficient cause so it is also the end of this motion For therefore doth the heat move the heart that it by this motion might impart heat to the body But I understand not here by heat a bare quality but that which is called Calidum innatum If it be objected that there is in Plants a vegetive faculty and heat but not this pulsifick motion nor yet in effects I answer the reason is because there are not instruments fit for such a motion nor is there any use of it 2. This motion of the heart is local not totally but partially for not the whole heart but the parts thereof change their place or seat and so in this regard augmentation and diminution are local motions XV. That the heart is not only first formed but is also first informed and first exerciseth the action of life is plain by this reason drawn from the Peripateticks the heart was made at first an Organical member but that could not be if it was not first informed by the soul which is the first act of the organical body and if it was made organicall it had been made to no end and nature had been idle to have made an useless member which could no more deserve the name of heart then a blinde eye the name of eye But the soul that I speak of here is the vegetive or sensitive resulting out of the matter which is first prepared in the heart for reception of it and not the reasonable soul which with all its perfections is created and infused by God into the whole body after it is articulated and made capable of such a noble Guest XVI The Aristotelians are more rational in placing but one principall member in the body then they who place either three or four For it is nedless to make so many principals when as one will suffice Nature aimeth always at unity for all the five senses are united in one common sense all the members in one body all the different specificall parts of the world into one common nature so all the members into one heart which hath in it the natures of all or their temperaments Nor could the soul being but one work upon so many different temperaments if they were not united into one temperament Besides we should be forced to run in infinitum if we should hold more principles then one for avoiding of which inconvenience we must stay in one chief principle If it be objected that the nerves veins and arteries are of different temperaments therefore must proceed from different principles I Answer that from one principle in which divers temperaments are united may issue different temperatures 2. I denie that the temperature of the veins nerves and arteries are different otherwise then Secundum magis
reparation by generation of spirits 5. It differs from the animal motive faculty because it is necessary and perpetual the animal is voluntary and sometimes ceaseth VII The vital spirits are ingendred in the left ventricle of the heart partly of aire prepared in the lungs and conveyed to the heart by the Arteria venosa and partly of the purest blood powred out of the mouth of Vena cava into the right ventricle where it is prepared and attenuated a part whereof is conveyed for nourishing of the lungs by the Vena arteriosa the other part sweats through the partition that divides the heart and in the left ventricle is mingled with the aire and turned into spirits by its excessive heat VIII The Diastole and Systole that is the dilatation and contraction of the heart and arteries is all one and at the same time for the heart and arteries are so united that they make but one body so there is but one pulsifick vertue in both and the end of their motion is the same to wit the vegitation and life of the body the suddenness of the motion in the remotest arteries from the heart and the strong beating of the pulse and heart in Feavers and anger do shew the identity of motion in both 2. The arteries are moved by the spirits of the heart conveyed by their tunicles rather then their cavity for upon the pressing of the tunicles the pulse ceaseth but not when the cavity is stuffed or stopped They are not then moved by their heat and blood but by the heart as may be seen by binding the arteries whose motion beneath the binding saileth the commerce between it and the heart being intercepted 3. The heart is first dilated by receiving the aire then it is contracted by expelling the fuliginous vapours 4. The heart strikes the breast in its dilatation not in its contraction or Systole because the left ventricle which is the originall of the Arteries is distended in the Diastole and so toucheth the breast about the left pap IX The motion of the heart is not voluntary because we cannot command it nor sensitive because it is not performed by the nerves and muscles nor simple because there are two motions nor compounded because they are contrary and of contrary motions can be no compositions nor is it violent because it is not repugnant to its nature nor is it caused by an externall agent as the trembling of the heart is by distempers vapours or humours but the hearts motion is natural yet not caused by the elementary form for so there should be more agents in our bodies then one and its motion should be â—itâ—eâ— upward or downward but it is natural in respect of the soul which is the chief nature that works in animal bodies and in respect of the fibers heat and spirits of the heart which are natural organs and in respect of the natural use or end of this motion for the heart dilates it self to receive aire and blood it contracts it self to be emptied of its fumes and to communicate its spirits to the nerves which ends are naturall X. When Aristotle saith that the motion of the heart is caused by heat and cold he contradicts not the Physitians in affirming the soul or its vital faculty to be the cause of this motion for heat and cold are subordinate instruments to the soul which by the heat of the blood and spirits dilates the heart and by the attraction of the cold air contracteth it as we see water by the heat of the fire swel and dilate it self but upon the breathing of cold air to contract and fall down again CHAP. XVI 1. The Lungs how moved the air is not the spirits nutriment 2. Respiration not absolutely necessary 3. The Lungs hot and moist 4. Respiration a mixed motion as that of the bladder and intestins 5. No portion of our drink passeth into the Lungs ARistotle differs from the Galenists about the motion of the Lungs he will have them moved by the heart whose heat listeth up the Lungs upon which motion the air enters for avoiding vacuity which being entred the Lungs fall The Galenists will have their motion to depend on the motion of the breast but both are in the right For the motion of the Lungs is partly voluntary and so it depends on the moving of the muscles of the breast and partly natural and so it is moved by the heart 2. When Aristotle denies that the air is the nutriment of the spirits which the Galenists affirm his meaning is that the air doth not properly nourish the spirits as meat doth our bodies for there is no assimilation or conversion of the substance of the air into our spirits which are properly nourished by blood but only a commixtion of the air and spirits for refrigeration And indeed if the spirits were properly fed by the air there would not come out the same air that went in For the spirits would not part from their food the air then nourisheth the spirits as it doth the fire by refrigeration and preserving it from suffocation II. Respiration is not so necessary for preservation of life as the motion of the heart for histerical women can live without that but they cannot live without this Neither is the motion of the arteries of absolute necessity for the member is not deprived of life though the arterie be stopped or tied and deprived of its motion 2. The motion of respiration is more noble then the motion of the heart because this is meerly natural that is also animal and voluntary yet as the motion of the Lungs is subservient to the motion of the heart that is more noble then this for the end excels the means III. The Lungs are hot and moist hot that they mighâ— temper and alter the cold air therefore the substance is fleshy light and spongy and fed with hot and spirituous blood from the right ventricle of the heart It is also moist as appears by its soft and loose substance It is also moist accidentally by receiving the flegme and rhumes that fall from the brain 2. The Lungs refrigerate the heart not because their substance is cold but because the air is cold which they attract IV. Respiration is a motion partly voluntary as it is performed by the muscles nerves and diaphragma which are the organs of voluntary motion and as it is in our power to breath or not to breath to hasten or retard it And it is partly natural as it is performed by the Lungs which are organs of natural motion as it is not subject to fatigation as it is performed in our sleep when we have no command over our selves and the sensitive faculties then cease as it is not performed by election or apprehension of the object as voluntary motions are And lastly as in Apoplexies when the senses fail the brains and nerves are hurt yet respiration continues it is then a mixt action as the expulsive actions of the

There is but one principal member in the body not many AS in all States and Kingdomes there have ever been factions and sidings so have there been still oppositions in the Common-wealth of Learning amongst many others there are two great factions concerning the fabrick of Mans Body namely the Peripateticks and Galenists so that in Rome there was not greater emulation between the Pompeians and Caesarians then there is between the Philosophers and Physitians in the points of Anatomy I stood as neuter a long time but at last being evinced by the multitude and strength of Aristotelian reasons am forced to side with them against the Galenists but so that I do what I can to reconcile them in some things and to make peace for Nulla salus bello I. I will therefore briefly set down the reasons that have induced me to side with the Aristotelians And first concerning the Heart I finde that it is the first member that lives and is formed in our bodies and consequently the noblest and chiefest of all our members whatsoever the Galenists say to the contrary For 1. The Heart is placed in the midst of the breast as the Sun in the midst of the world that it might impart its vital heat and motion to all parts So the seed is in the midst of the fruit 2. Where there is a medium there must needs be extreams but we finde in mans body this medium to wit that there are some parts which both give and receive life and motion therefore there must be some that receive but give not and consequently some that give but receive not and this must be the heart or brain or liver for to make more originals then one is needless seeing Nature always tends to and aims at unity Now that the heart is this principal appears by these reasons 3. First that is most likely to be the originall of life sense and motion in other members which is most apt and capable of these and so that had first life and motion which had the greatest inclination and aptitude to receive them but the heart of all other parts is most apt to receive these from the formative faculty Therefore doubtless this faculty in the seed would first produce the heart as being a matter prepared to receive first the impressions of the formative 4. What the heart is in Animals that the root is in Vegitables but the root is the first thing the plant thrusts out therefore the heart is first formed 5. The heart dieth last therefore it lived first for this method Nature observes that the parts which are last made decay first as the eies and teeth and consequently that decayeth last which was framed first 6. They that have been curious by inspection into eggs to observe Natures progress in the generation of the chick have found a red spot the third day which had a motion like palpitation this could be nothing else but the heart 7. The other members cannot live without the heart but the heart can live without the other members as I have seen a Monkeys heart live a great while after it hath been taken out of the body If then the life of the other members depends from
the superfluous moisture of the body by the natural heat be exhausted and the organs made drier 3. The bodies of other creatures are not capable of mans soul because they are not of that fabrick temper and constitution 4. The faculties of the animal soul have not their originall from the gross and earthy part of the seed but from the aereal by means of its celestial heat 5 The rational soul bringing with it all its perfections the former faculties of sense and vegetation which were in the Embryo give place to it so that now it alone works by its faculties 6. The seed brings with it from the parents it s own heat by which the formative faculty worketh the heat of the matrix is not operative but conservative of the other heat 7. The seed consisting of grosser and aereal parts cannot be called uniform and if it were yet it may have divers operations and faculties ad extra so hath the Sun and other uniform bodies 8. The Embryo is not capable of three specificall forms or souls for so it should be a threefold compound specifically distinct but it is capable of divers generical forms and subordinate the superior being preparatives for reception of the inferior and ultimate specificall form which giveth name and entity as the rational soul doth to the child being perfected CHAP.

How câ—used AS soon as the child groweth big about the fourth month the menstruous blood flowes upward to the breasts and when the child is born it flowes from thence and being suck'd by the child the veins of the breasts do avoid vacuity draw the blood upward for generation of new milk 2. In the breasts of Virgins and of some men also there is sometimes found a whitish liquor which is not milk because it hath neither the tast nor thickness nor nutritive quality of milk 3. The breasts or paps are glandulous bodies principally ordained for generation of milk and in the second place for reception of excrementitious humors and guarding of the heart 4. The reason why about the fourth month the blood flowes upward into the breasts is that the child growing big and wanting sufficient food might struggle to get out which it would not do having sufficient nutriment 5. It is not fit that the child out of the womb should feed on blood as it did in the womb because then the mouth of the veins being opened the blood would run out and so nature be overthrown neither would God accustom man to blood left he should become cruel and bestial II. Upon the inflammation of the diaphragma follow oftentimes phrensies by reason of the society it hath by the nerves with the brain to which it sendeth fumes and hot vapors which phrensie is known from that of the brain by the shortness of the breath the chief organ of breath being ill-affected so that the breast cannot freely move it self and because the Diaphragma is united to the Pleura and Peritonaeum which containeth all the organs in the inferiour belly hence all these parts are drawn upwards by the motion of the Diaphragma III. The tunicle of the heart called Pericardium hath within it a water for refrigeration and moistning of the heart which is begot of vapours condensate by the coldness of the membrane as some think or else it sweats through the tunicles of the veins and arteries they that have hot hearts have but little of this water and it abounds most where the heart is colder but whether the defect of this water be the cause of the heat in the heart or the heat the cause of this defect it is uncertain as it is with the sea-water which is turned into vapours by the suns heat and these vapours turned into water again by the coldness of the middle Region so the heat of the heart turns this water into vapours and the membrane converts these vapours into water again and so this circulation continues till the heat of the heart be extinguished by death then is found water onely IV. The heart hath a peculiar hard flesh of its own that it might be the better able to undergo its perpetual motion to contain the spirits and life-blood and to resist external injuries 2. This flesh is not musculous because the motion of the muscles is voluntary but the hearts motion is natural 3. The heart hath both straight transverse and circular fibers for attraction and expulsion and oblique fibers also for retension but these fibers are of the same substance with the heart and not of a different as the fibers of the Muscles which are parts of the nerves and Tendons 4. The heart is fed with gross blood answerable to its own gross substance by the vein called Coronaria compassing the Basis of the heart 5. The heart hath two ventricles whereof the right is hottest extensive as Aristotle will have it for it contains the life-blood the left is hottest intensive as containing the vital spirits and so Galen saith 6. If we consider the situation of the right ventricle which is in the right side and the priviledge it hath in living longer then the left we may with Aristotle say that the right ventricle is the more noble of the two but if we consider that the left ventricle contains the vitall spirit which in dignity excels the blood which is in the right we must with Galen give the preheminence to the left and so these two may be reconciled V. The heart is a hot and drie substance that it might be the fitter both to beget and to preserve the vital spirits to attenuate the venal and to procreate the arterial blood And though the spirits be hotter extensively yet the substance of the heart is hotter intensively as burning coles are hotter then flaming straw VI. The vital faculty by which the vital spirits are ingendred for animating the body and preserving the natural heat is an effect of the soul as all faculties are and not of the heart yet here it chiefly resides because of the soul which here exerciseth her chief functions of life 2. This vital faculty differs from the animal because it is not subject to fatigation nor rests in sleep nor doth it accompany the imagination or apprehension of the object as the animal doth 3. It is different from the pulsifick faculty because this is subservient to the vital neither doth the pulsifick beget spirits or is it diffused every where as the vital is 4. The vital differs from the vegitive faculty because the vegitive is in plants and insects but not the vital as it is procreative of spirits for the dull heat of insects is not so soon spent as to need
the heart and not the heart from them the heart must needs be the first that liveth 8. The heart imparts the vitall heat to the other parts it must therefore have existence before the other parts for operation follows the existence 9. The formative power of the seed doth not operate but by the vital heat of the heart therefore this must be first before that can operate 10. The matter cannot be disposed to receive the form of the members nor can the parts be distinguished one from another without the heat and motion of the heart 11. Nature in her operations aims at an end but where there is an end there is order and where there is order there is priority and something that was first II. There are some who hold that the heart is not first generated but that all the members are at the same time begot and formed together But this cannot be so for in the Embryo we see that all the parts are not equally articulated and figured but some sooner some later 2. We see this in art which imitates Nature for the artificer carves and figures one part before another 3. We see the teeth are begot long after the other parts for nature produceth the members as there is 〈◊〉 of them the infant needs no teeth whilst it feeds on milk 4. If all the parts are at the same time framed and articulated then all the body is at the same time perfected but this is not Natures work which proceeds by degrees to perfection having imperfect beginnings III. The Galenists object that Nature had to no purpose made the heart before the rest of the body seeing there is no use of the heart till the body be formed I answer there is a two-fold use namely of Animation and of preparation the heart could not animate the body before it was but it could prepare the matter by its vital heat and motion to receive the impression and influence of the formative power working by the heart on the matter the heart then is usefull not only to the body after it is generated but also whilst it is in Fieri and in generation the heart is the foundation of the whole corporeal Fabrick we cannot say the foundation is needless because it is laid before the house is built for though it doth not support the superstructure before it be yet it is ready and sitted to support it when it shal be Neither will it follow that because the house before it is built needs no foundation therefore the foundation must not be first laid There is need of priority and order the building needs it when it shall be and the builder needs it before it be though the body not yet formed needs not the heart yet the formative power needs it Secondly they object that the formative power is common to all the parts alike having no more relation to one then to another and therefore works upon them all alike and produceth them together I answer God is the common and universal cause of all his creatures yet he did not create them all in one day the universality of the cause excludes not the order of casuality nor is the common relation it hath to the effects any reason of producing them all at one time Again though the formative power hath an equal relation to all parts as they are parts yet it hath a nearer relation to the heart as being its organ by which it works on the other parts IV. If it be asked whether the heart be perfect or imperfect before the other members be articulated I answer It is perfect if it be compared with any other member but imperfect if compared with the whole compositum Again it is imperfect to what it shal be when it shall be fitted with all necessary Organs for animation 2. If again it be asked how the heart can live without nutriment seeing the liver by blood feeds it I answer though the liver be not yet formed yet the heart is nourished by some adjacent matter as the chick is by the yeolk of the egg and this nourishment sufficeth the heart till blood a perfect nutriment be prepared Again the nutritive faculty doth not flow from the liver as the vitall from he heart but it is inherent and implanted into every part as well in the heart as in the liver whereas the vitall is implanted only in the heart and from thence flowing into every member Lastly we may say that the heart needs no food till there be a dependition or wasting of its substance V. The unity of the vegetive soul cannot be preserved in so many different temperaments or the body for there are as many as there are parts if it were not for the common temperament of the heart in which all the others are united receiving from thence heat and spirits It was needfull then that the heart should be first formed as being the common originall of all the other parts all which may be said to have but one common temperament and one soul because there is but one heart VI. Though the Galenists affirm that the heart hath but two ventricles yet the Aristotelians in affirming three in bigger creatures seem to speak more reason For if in bigger animals there is greater store of spirits and a greater elaboration of them then in the lesser it stands with reason that their hearts being bigger should have also more receptacles for containing the vitall blood and spirits then the lesse VII It stands also with reason that the substance of the heart is nervous that it might be the more firm and solid 2. Because the heart is the original of motion which is performed by the nerves 3. Because the substance of the veins and arteries whereof the heart is the originall is nervous VIII The parts which the Galenists call Spermaticall are not made of the Sperma or Seed more then any other parts are but of the dryer and more solid parts of the blood as the Sanguineall are of the thinner parts thereof 2 The males seed is onely active the woman hath no other seed then the menstruous blood which is meerly passive in both which seeds there is a power or potentiality of generation the active in the male the passive in the female both which are from the heart In this also I subscribe to Aristotle IX I cannot assent to the Galenists in affirming the liver rather then the heart to be the first that lives in us and therefore the original of other parts because it is bigger and nearer to the matrix then the heart for the Aristotelians say well that the original of things consisteth not in bulk but in vertue the seeds of trees and plants are least in bulk and yet are the originals of great bodies 2. The vicinity to the matrix is not the cause of priority for the matrix is the place of but not an agent in generation the agent is only the formative faculty in the seed
motions from divers muscles 2. The muscles of the abdomen are chiefly made for pressing of the same when nature desires to expel the excrements and in the next place to move the breast with the other muscles appointed for respiration 3. The muscle of the bladder called Sphincter was made partly for opening a passage for the urine to passe away which it doth by dilating and extending it self and partly for shutting up of the bladder by contracting it self lest the urine should passe from us in sleep or against our wills whilest we are awaked 4. The muscle called diaphragma or the midriff was made for exspiration and inspiration in inspiration it dilateth it self but in expiration it is contracted upward as we see in dead bodies 6. The muscles of the ribs called Intercostals are some of them external which distend the breast for inspiration some internal which contract the breast for exspiration VI. Aristotelians will have the flesh Galenists the skin to be the organ of tact but I think both are for I take the skin to be nothing else but the outward superficies of the flesh a little dried and hardned and differing no other way from the flesh then the outward skin of the apple from the softer substance thereof so then the flesh both as it is a soft substance and as it is hardned in its outward superficies is the organ of tact by means of the nerves and fibres diffused into it and whereas vision hearing and smelling have the air for their medium tact and taste which are the two absolutely needfull senses without which we cannot live whereas without the other three we may have no medium at all CHAP. VIII 1. Bloud milk c. No integral parts 2. How the parts draw their aliment 3. And expel things hurtful 4. Of the intestines and faeces 5. The intestines retentive faculty 6. Of the stomach and its appetite or sense 7. Whether the stomach is nourished by Chylus or bloud I BLOOD Milk Fat Marrow are not properly integral parts of our bodies for the body is perfect in its limbs and members without these and these in time of hunger nourish the body whereas one part cannot be the aliment of another besides every part hath its figure and shape but these have none yet in a large sense they may bee called parts as they help to make up the whole II. As the Loadstone draweth Iron and Plants nutriment from the earth so doth every part of our bodies draw that aliment which is most proper for it some by the help of the fibres as the heart in its Diastole draws blood from Vena cava into its right ventricle by the help of the fibres some without their help as bones grissles and ligaments So the Intestines draw without fibers the Chylus from the Ventricle with which they are delighted and they draw blood from the Meseraick veins with which they are nourished and the same veines draw the purer part of the Chylus from the Intestines for sanguification III. The same part that draws things needful expels the same things when they grow superfluous or hurtful thus the ventricles expel the Chylus into the Intestines and these expel their grosâ—er and excrementitious parts out of the body so the heart expels by its transverse fibers blood and spirits and hurtful vapours too And indeed nature is more solicitous in expelling of things hurtful then in attracting of things needful Thus we see in dying people that expiration is stronger then inspiration nature being more willing to be rid of hurtful vapours then to receive fresh aire so when the intestines are affected with inflammations obstructions or ulcerations that they cannot send the excrement downward they force it upward into the stomach again and so expel it by the mouth as in the Iliaca passio IV. The expulsion of the Foeces is partly the natural or peristaltick motion of the intestines and partly the voluntary motion of the muscles of the Abdomen which muscles being contracted presse the intestine 2. There are straight Fibeâ—s in the intestine called Rectum not so much for attraction as for strengthning the circular Fiberâ— 3. The Colon is sâ—ated uppermost neer to the bottome of the stomach and hollownesse of the liver thaâ— by the touch of these parts the remainders of the meat which are in the cels of the Colon might be better concocted 4. The stink of the foeces proceed partly from the superfluous humidity which is the mother of putrefaction and partly from the heat of the intestin which though it be natural to the aliment which it concocts yet it is external to the excrement which it expels 5. The length of the intestins which are seven times as long as the body and â—he many windingâ— or folds of them besides the Valâ—ula or shutter in the end of the Coecum do shew that the injections by the fundament can ascend no higher then the blind intestine except there be any of those three distempers in the guts which I mentioned but now or else the stomach be distempered by Bulimia for in such a case it will draw the foeces to it 6. Clysters are sometimes carried to the liver by means of the meseraick veins which suck some part of it from the intestins V. The substance temper and colour of the intestines and ventricles is the same therefore the Chylus is not only concocted in the ventricle but in the intestins also and as the one of these members is affected so is the other 2. As in the intestines there is an attractive concoctive and expulsive faculty so there is also a retentive for all these affections are in the ventricle which is of the same substance with the intestines To what end are stiptick or restringent medicaments used in Fluxes but to corroborate the retentive faculty of the intestins in the lientery the meat passeth away without concoction because the reâ—â—ntive faculâ—y both of the ventricle and intestins is hurt VI. The mouth of the stomach being united to the Diaphragma and this to the breast-bone is the cause that we find much pain about this bone when the mouth of the stomach is ill-affected 2. In the mouth of the stomach is the â—eaâ— of appetite by reason of the two stomachical nerves thâ—re which when they are refrigerated or obstruâ—tâ—d the appetite is dissolved as in Bâ—limia where there is a continual attraction from the stomach but no sense or appetite but when the stomach is molested with cold and sâ—wre humours there is a continuall sense or appetite though there be no inanition of the part as in the disease called the Dogs appetite 3. By reason of the sympathy that is between the mouth of the stomach and the heart they had of old the same name and they have the same symptomes 4. The appetite being an animal faculty â—ath its seat in the braine originally in the stomach subjectively the faculty is in both but the action onely in the stomach VII
