A37987	A demonstration of the existence and providence of God, from the contemplation of the visible structure of the greater and the lesser world in two parts, the first shewing the excellent contrivance of the heavens, earth, sea, &c., the second the wonderful formation of the body of man / by John Edwards ...	Edwards, John, 1637-1716.	1696 (1696)	Wing E201; ESTC R13760	204,339	448

as Bellows are because they are distended or whether as some of late contend they are dilated by the elastick Force of the Air rushing in and so upon their Extension follows the swelling of the Diaphragm and thereupon the Motion of the Thorax This is Inspiration And then in Expiration the Diaphragm is contracted and returns to its right Figure and the Air is expelled Neither will I question Whether it be a collateral End of Respiration to discharge and expel an excrementitious Fluid out of the Mass of Blood as the excellent Author whom I have formerly cited thinks he can sufficiently prove But this we are sure of laying aside all Disputes that the Lungs are the great Instrument of breathing and that they are absolutely requisite for the admiting of the Air in order to the rouzing of the vital Spirits and quickning and maintaining the Flame of Life for the sensitive Soul is fed by Air as the Body by Food And we are sure of this likewise that they are necessary Organs of Speech and Voice of articulate and significant Sounds And we have no reason to doubt of this that the great Architect and Framer of Man's Body hath particularly fitted and composed the Lungs for these Purposes for they are light spongy and flexible and full of hollow Places to hold the Air and convey it through hidden Passages to all the Body And they are wide and capacious that the Air may play in them and have its full Scope in the Cavity of the Thorax And moreover that they may be firm and steady and so perform their Operations with the greater Certainty and Accuracy they are on the Back of them fastened to the Spina and thereby become fixed This may convince us that they are the Work of a supreme and primary Cause who is Owner of infinite Understanding and doth all things with Skill and Counsel Wherefore that is an excellent Spark of Devotion in the Talmud At every Breath that a Man breatheth he ought to praise God his Creator The other rich Treasure in this Chest is the Heart the Fountain of natural Heat which it disperses over all the Body by vertue of its peculiar Office which is to make Blood and to distribute it by the Arteries into the Parts Whether the so deservedly admired Motion of the Blood be from an infinite Faculty as Galen thought or from Rarefaction which expands the Heart as Cartes determines or from the Air taken into the Lungs as Mr. Hobbes suggests or from the Quantity or Copiousness of the Blood falling into the Heart which labors to expel it thence by a Constriction of its Fibres whereby the Cone of it is brought nearer to the Basis as Dr. Charlton thinks I will not here dispute but this we are certain of that an intellectual Spirit was the first Cause and Efficient of it And any considerate Man that takes notice of the wonderful Make and Figure of the Heart and of all the Vessels subservient to it cannot but acknowledg as much Therefore a celebrated Anatomist of our own resolves the Motion of them and of the Blood into a divine and supernatural Principle not to be conceived and explained by us We know that when the Blood flows into the right Ventricle of the Heart this is dilated and when it is thrust out thence this is contracted but the true natural Spring of this double Motion is hid from us Whether the Motion of the Heart depend upon the Blood or the Motion of this depend on the Heart because if it be a great Muscle as not only Hippocrates and Galen but some modern Philosophers and Physitians have averred it seems of it self to be made for Motion being actuated by Spirits and drawn by Fibres it is not my Business here to enquire but this is the thing which ought to employ our Thoughts and excite our Devotion that whatever second and natural Causes may be assigned of this Phaenomenon the supreme Author and Contriver of it is some intelligent Substance and it is impossible it should be otherwise For the whole stupendous Contexture of the Heart and its double Ventricle with the four Vessels in them viz. two Veins in the right and two Arteries in the left Side the former to convey the Blood to the Heart the latter to carry it off together with the various Nerves Fibres c. is a Work of Understanding Prudence and Judgment for all these Parts have Relation to one another and are mutually helpful in their Operations and they all apparently conspire for the Good and Welfare of the Body Who can sufficiently admire the Circular Conveyance of that noble Liquor through the greatest Vein of the whole Body into which all the other Veins empty and disembogue their Blood into the right Ventricle of the Heart out of this into the Lungs through a capacious Artery falsly called a Vein which hath its Original from the Heart and is divided into many Branch●s which are dispersed through the Lungs out of this Parenchyma of the Lungs into the left Ventricle of the Heart through a remarkable Vein corruptly call'd an Artery which hath its Rise from the Lungs and is mixed with the Branches of the Aspera Arteria and the Arterious Vein And so when the Blood is digested and perfected in both those Ventricles of the Heart and Lungs it is carried out of the left Ventricle into the bigger Sort of Arteries through the great Artery which proceeding out of the Heart disperses its Branches through the whole Body and out of the lesser Arteries not by Anastomoses or Inosculations as some have thought but through the Substance of the Flesh into the lesser and then the greater Veins and thence thro' the Vena Cava into the right Ventricle of the Heart again and so the Circulation is made Or the short is that the Heart hath on one side of it the Vena Cava and on the other the Arteria magna both which great Trunks have Branches dispersed through all the Body even the extremest Parts and are continued to one another by capillary or small Vessels and so there is no Interruption of the circular Course of the Blood but it returns to the Place from whence it first set out These are the Journeys of the Blood these are its several Stages these are the distinct Chanels and Vessels it moves through Thus by the Heart and other Passages as 't were in a Water-engine it is carried in a constant Course round Which is a sufficient Evidence that these Machines were at first made and then set into Motion by an omnipotent and wise Being And the Speediness of this Motion is as remarkable as the Circulation it self For from the Pulses which are the sensible moving and beating of the Arteries and are made as often as the Blood rusheth out of the Heart into these Vessels we may gather the swift Career of this liquid Substance Primrose is singular in

viz. the Stomach And though all is done here in a natural way yet it was caused at first by a supernatural Efficient the supreme divine Author of all things who framed this Vessel after this particular manner and most wisely designed and contrived the Operation and Office of it in order to the nourishing and sustaining of the whole Body Which will appear if we consider what becomes of the Chyle that milky Juice into which the Food is here dissolved It is sent through the lower Orifice or Mouth of the Stomach into the Guts which are fitted and prepared on purpose to receive it and to give it a farther and higher Digestion Properly there is but one Intestine which hath divers Names according to its divers Parts or Offices That which immediately adheres to the Bottom of the Stomach hath its Name from its being thought to be in its full Dimensions twelve Fingers in Length though the expertest Anatomists find it not half so long This hath no Windings but descends streight from the Pylorus that the Chyle may pass thence the better And it hath a narrow Cavity that it may pass by degrees and not all together The next for I will mention them all because they have some particular Service though not very distinctly known to us is the hungry one so call'd because it is often empty by reason of the abundance of lacteal Veins that are there which suck up the Chyle The third is much larger than these two before mentioned and is therefore capable of receiving more of the Faeces and of retaining them a longer time Here is the Iliack Passion Note that these three first Intestines are generally known by the Name of the small Guts The fourth is an obscure or blind Appendix whence perhaps it hath its Name of the Intestine last mentioned and of that which I shall name next for it rises out of the End of the one and the Entrance of the other It hath its peculiar Use in the Reception of the Excrements in preparing them for Ejection in correcting the Flatus that proceeds from them and in serving also as a Ligament to fasten and uphold the Peritonaeum The fifth is the largest and thickest of all and the chief Receptacle for the Faeces Here is the Scene of the Cholick Pains bred of Winds and Vapours which arise in this lower Region of the little World Lastly there is the streight one so nominated because it directly tends to the Anus And here for there are Wonders in every Part of the Body between the Podex and the Vesica is that so useful and excellently contrived Muscle whereby untimely Excretion is prevented and hindred the Benefit of which cannot sufficiently be expressed I may justly call it the Key of the Postern-Gate of the Body with which it is opened and shut as often as there is occasion which is a thing not only of singular Use and Convenience but of absolute Necessity And as for the more general Use of the Intestines it is very observable and worthy of their Author For first they were designed to retain the Nourishment a considerable time in order to its better Fermentation and Concoction To which purpose they are made of a round long and concave Figure that they may be more capacious and hold the Chyle the longer time and that they may be the fitter for Motion Secondly the Intention of them was to separate what is brought into them the useful Parts from those that are of no Use. Thirdly to convey and distribute the wholesome Portion of the Chyle into its proper Receptacle for the Nourishment of the Body Fourthly to expel the useless Parts and Sediment downwards And though the other Employments be more honourable yet this is as necessary and admirable as they To these Ends their peristaltick Motion was given them which is singular and peculiar and ordained for this very purpose and no other By this Motion which is compared usually to that of Earth-Worms which move the Parts of their Bodies successively and gradually the pure profitable and defecate Parts of the Chyle are separated from the Excrementitious and the Faeces are by degrees depressed and carried off That there should be this peculiar Contrivance of these Parts and that they should have spiral Fibres peculiarly fitted for the Employment they are designed to whilst other Parts have Fibres of a quite different Nature shews whose Workmanship it is And the many Turnings Foldings and crooked Windings of these Vessels were designedly framed by God for the promoting of these Ends. Hereby the Chyle hath time to digest sufficiently and to send laudable Nourishment to the Body Otherwise it would too soon be ejected and precipitated If the Intestines had not these Windings we should be always hungry because the Meat would slip out of the Stomach too soon Therefore when there hath been the contrary Make of the Guts a perpetual Appetite and Voracity have been observed of which see Instances in Riolan Anthrop l. 2. and Cabrol Observat. 10. Nature doth not perform its Work too fast but leisurely and sedately by Help of these Meanders and anfractuous Passages of the Entrails I have only this to observe further that all the Intestines are joyned together by the Mesentery that they may not be loose and they are also fastned to the Vertebrae of the Back But because both the Stomach and Intestines were primarily intended for conveying and dispersing the useful and nutritive Part of the Food into the several Parts of the Body I will proceed to shew you the manner of this particular Conveyance and Distribution one of the greatest Arguments of the divine Contrivance of Man's Body that we can desire The Food i. e. the major Part of it being converted into Chyle in the Stomach and afterwards by the Contraction of its Fibres detruded down into the Guts the more tenuious Parts of it are directly conveyed to the lacteal Veins which are dispersed through the small Guts and the Mesentery Here is the first Preparation of the chylous Matter after its Descent out of the Stomach Then from these milky Veins 't is carried to the common Receptacle which is of a membranous Substance and is placed at the Root of the Mesentery and above the Vertebrae of the Loins to which it is fastned though some have lately exploded this common Receptacle of Pecquet From thence it ascends to the Ductu● Thoracicus and thence into the subclavian Veins call'd so from the Claviculae or Chanel Bones by which they pass and thence it flows into the upper Trunck of the Vena Cava where 't is mixed with the Blood and thence it runs directly into the right Ventricle of the Heart in its Diastole where 't is turn'd into Blood And thence into the Lungs by the Heart's Systole Thence into the left Ventricle of the Heart whence passing through the Aorta or great Artery it is poured into the Arteries of

his Opinion and reckons but seven Hundred Pulses in an Hour Other Physitians rise much higher but with great Inequality they being more used to feel than tell the Pulses Harvey reckons two Thousand Regius three Thousand Bartholine about four Thousand for according to the different Temper and Habit of the Body the Agitation of the Blood varies and consequently the Circulation of it is finished sooner in some than in others If we speak of what is commonly experienced in most Persons that are healthful and well disposed in Body and are of a just Stature it is generally agreed that the Heart usually gives in the Space of an Hour about three thousand Strokes The whole Mass of Blood which in a Man's Body who is adult seldom exceeds Twenty four Pounds Weight or is less than fifteen passes through the Heart and whole Body six or seven times in an Hour in some oftner in others Yea a late learned and applauded Physitian tells us that in some Persons all the Blood passes through the Body thirteen times in one Hour And he endeavours to shew exactly that the Situation and Structure of the Heart are fitted for this swift Motion that the Vessels are wonderfully made to distribute the Blood through the Body in so short a time and to perform their whole Circle and Periodical Revolution This more particularly may be observed that this noble Mover is placed exactly in the Middle of the Breast and in a manner of the whole Body that the Influence of it may equally reach all Parts Though indeed the Pulse is more sensible on the left Side which is by reason of the left Ventricle wherein the vital Spirits are elaborated and where is situated the great Artery that conveys them forth thence both which are on the left And besides the Cone or Point of the Heart deflects rather to the left Side to give way perhaps to the Ascention of the Midriff That this choice Vessel of the Heart may be defended and preserved it is encompassed with the Lungs which hang on both sides of it and are call'd by some Anatomists the Hearts Pillow And add to this that this precious Treasure is enclosed in a Membranous Covering which is stiled the Pericardium As the Heart is fastned to a Part of the Spina to keep it steady so this Capsula is fastned to the Midriff to keep it in its right Situation and also to defend it from Injuries And it is not to be omitted that within this Membrane there is a serum or thin Liquor which is placed here on purpose to keep the Heart moist and consequently to promote its Motion Whereas if the outward Superficies of the Heart were depriv'd of this serous Matter it would it is probable through continual Agitation and Heat grow dry and wrinkle and be made unfit for Motion This Lympha therefore is of great Use and as all the other things before mentioned convinces us that the Fabrick of the Heart was from an understanding Mind and could not be from any other And after all this may be observed which is very strange and wonderful that the Heart is insensible as Dr. Harvey proves from one who had a Fracture in his left Side so that this Part was exposed to view and was handled but not perceived So much for the Heart which is the lower Heaven as 't were in this little World the Head being the upper one where the divine Soul hath its Throne Having viewed the middle Cavity or Partition of humane Bodies and having found it to be a Structure worthy of its Creator I should now with religious Admiration pass to the lowest Region of the Body which answers to the Earth in the sublunary World But because this is separated from the foregoing Region by a certain cross Bound called the Diaphragm or Midriff we ought therefore to take notice of that first This Muscular Partition lies over-thwart the lower Part of the Breast and is sometimes known by the Name of Praecordia because the Heart touches it with its Cone Through this fleshy Skin the Gullet descends And to this Part likewise the Pericardium the Liver Spleen Stomach are all fastened whence there is a Communication between them and it The Use of this Partition is to divide the vital Parts from the natural ones i. e. the Heart and Lungs from the Stomach and other lower Bowels as it was fit there should be a Distance between these Parts of so great Difference in their Nature and Use therefore this Wall was made between them Again it is useful to help the Exoneration of the Intestines for by pressing these the Faeces are more easily evacuated But its chiefest Use is for Respiration for by contracting it self it extends the Breast and by that Extension is Inspiration wrought So by extending it self it contracts the Breast and by that means Expiration is performed Thus it is next to the Lungs which it immediately touches as well as the Heart the principal Instrument of free breathing And besides these Uses already mentioned it is concluded by the most judicious Searchers into the Secrets of Nature that this Part of the Body is useful for Laughter that innocent and healthful Diversion of Man's Life if it be used lawfully and moderately For this peculiar Posture of the Countenance with that sonorous but inarticulate Voice which attends it is to be ascribed in great part of the shaking of the Muscles of the Diaphragm caused by an Agitation of the Spirits dilating the Heart and consequently this Part and the Breast which being moved affect the Muscles of the Face and cause this pleasant Figure of it Hence one of our learnedest Masters in Physicks gives an Account of this particular Motion of the Countenance from the peculiar Frame of the Midriff and the Heart of Man which is different from that of all other Animals This is the Reason why Laughter is proper to Man only And the same inquisitive Person takes notice that the intercostal Nerve is of a particular and unparallell'd Composure in Man whence there is a wonderful Consent between the Praecordia and the Parts of the Mouth and Face insomuch that assoon as Grief invades the Breast the Face corresponds and is troubled Hence Men of all Creatures only weep as well as Laugh This we may entertain as a Truth whatever Virgil or Pliny suggest to the contrary who tell us of weeping Horses But every Moisture or Distillation from the Eyes which is seen even in some Brutes sometimes is not to be call'd Tears Homer who tells us of weeping Horses mentions speaking Brutes of the same Species he that gave them Tears could give them humane Speech And the same Poet talks of immortal Horses that feed on Ambrosia instead of Oats or any such ordinary Provender There is no Creature properly speaking weeps but Man for this comes from that inward Sense and Perception which are not in irrational Animals

the whole Body and thence returns again by the Veins For the lesser Veins bring it to the Vena Cava and from thence as was said before into the right Ventricle of the Heart Or briefer thus the prepared Chyle which is the nutritive Part of the Food is carried to the Heart by the Veins sent about by Arteries and goes back again by Veins This is the Passage of it this is its constant Circuit However though we may be mistaken in some of the chyliferous Passages yet as to the main the Progress is rightly stated and we cannot but acknowledge as the learnedest Enquirers have done that the Motion of this liquid Matter from one Place to another is surprizing and amazing The various Stages of it its sudden mounting and climbing up even from the Intestines to the Thorax its making way through so many different Chanels is all of it divine and heavenly Mechanism None can see and observe these things but they must be confirmed in the Belief of a God And now I should say something particularly of the Liver and Spleen though I had occasion to mention them before and observed they were a Guard to the Stomach and on that account were of use The former of these was said by the Ancients to be the Blood-making Vessel but now 't is otherwise agreed by the learned viz. that the Blood is made in the Heart Wherefore they assign that Part other Offices which yet are of no mean Advantage to the Body Dr. Glisson is of opinion that the Liver is of the Nature of a Streiner i. e. the Blood and other Humours are defecated as they pass through it And moreover he thinks that it promotes the Fermentation of the Blood running through it But those who are perswaded that no Chyle or Blood is carried to the Liver because Anatomists do not find any Passage from the lacteal Veins thither assert that the chief Employment of this Part is to separate and prepare Choler for the use of other Parts of the Body and that the grosser Part of it is derived by the Gall-Bladder and Bilary Passage which are in the hollow Part of this Viscus into the Intestines to promote and facilitate the Evacuation of the Excrements out of those Parts which are thereby rendred fluid and so fitter for Motion But the better and milder Part of this Juice is sent into the Blood continually and is very serviceable to augment its Fermentation I will not interpose here to examine or judge which of these Opinions is most probable but any Man of rational Thoughts will determine that a Part of the Body which is of that Bigness and Consistency that the Liver is of was not placed there without good reason and for some considerable End Then as to the Spleen it was thought by the Ancients that its Employment was to separate the melancholick Part of the Chyle and to contain it in its particular Cavity as the Gall-Bladder is the Receptacle of the yellow Choler and after Concoction of it to transmit some of it to the Entrails some to the Veins and some to the Stomach Others lately assign other Offices of the Spleen but cannot well agree what they are Dr. Glisson will have it to be useful for the preparing of his succus nutritius Others think it is serviceable for the gathering and dreining of a certain acid excrementitious Juice But the most probable Function of it is to help and further the Ferment of the Blood and to advance its due Concoction in the Body It is certainly a necessary Vessel in humane Bodies and cannot be taken out of them without real Damage to them though some other Animals may make a shift to live without it after 't is cut out Or that a Man may live without it perhaps may not wholly be denied but yet 't is useful to the Health of the Body for a thing may be useful though not absolutely necessary Hear therefore what a Person of Understanding and Judgment in these things hath said The great Architect saith he never made any thing in our Bodies to no purpose What Man therefore in his right Senses can believe that so eminent and large a Bowel as the Spleen is should be given in vain to Men and Beasts without any Necessity or Use in order to Life And so I doubt not but the Pancreas or Sweet-bread which is a glandulous Substance seated under the back Part of the Stomach at the Bottom of it and so is as it were its Cushion to lean upon is of considerable Use in the Body It is said by some to send a Juice to the Stomach in order to the Concoction By others it is thought to afford a Liquor to the Guts for fermenting the Chyle there It is concluded by others to be a Dreyner viz. of some useless excrementitious Humour that passes that way Thus Physicians and Anatomists disagree about it some asserting one thing some another And here let me say this with relation not only to this Part but to those immediately before spoken of that though we have not a particular or full Knowledge of the Use of them yet we ought not to conclude thence that they are useless But rather as one of the Ancients said of Heraclitus's Writings that what he understood of them was good and he thence gathered that what he understood not was so too the like we may in a resembling manner say of the Parts of the Body we have a full Proof concerning most of them that they are very useful and there is reason to infer thence that the rest are of the like Nature though we cannot give a particular and distinct Account of them And now I will shut up all that I have to say concerning this last and lowest Region of the Body when I have observed to you that this being the only Partition that is not guarded with Bones for the Ribbs came no farther before than the Diaphragm there is other Provision made for it for it is in a special manner fenced and secured though not with Bones yet with several other Coverings As first there is that Skin which is called the Rim of the Belly This covers all the Entrails and not only defends them but keeps them warm and likewise keeps them together and thereby prevents a Rupture There is another Skin or Membrane which wraps up the Intestines and that is the Cawl or Kell This is under the Rim and is not so large as that but it is useful for the foresaid purposes and also to keep the Bowels glib by its Fatness and Moisture not to speak here of its Serviceableness to Concoction which might have been mentioned before for when this Part is corrupted and defective Digestion fails of which see an Example in the Philosophical Transactions Aug. 20. 1684. Furthermore there is the Mesentery in the middle of the Entrails which is another Tye and Security to these Parts for it laps them close
