T he receiv’d Opinion of the Tex. ture of the Animal Body, is,-That it Is a Compages of Veflels, va- riouQy difpos’d, to Form Parts of different Figures, for different Ufes. The Ancients fuppos’d. That the Heart and Brain were firft form’d, and that all the other Parts proceeded from them : They diftinguifh’d them into Spermatic and San- guineous-, and thought, bccaule the Brain was cover’d with Two Membranes, that all the other Parts muft be fo too ; and frequently ingag’d themfelves in Difputes about the Derivation of Parts ; with many other Things of the like Nature, Confe* quences of their Hypothejis. But the Mo- derns, alliffed with Glaffes, have difcover’d, That all the Parts exiff in Miniature, from, the firft Formation of the foetus, and that their increafe, is only the extenfion and thickning of their Veffels, and that no Part can owe its Exiftence to another. Thus XX Introdudtion. ’ Thus much we thought neceflary to Premife, that the Reader might have a general Idea of the Body, and that he may lee for what Reafon we take no Notice in this Treatife of the Diftinftions and Divi- fions of Parts, made by ancient Jmtomijls, and thofe who have Copy’d after ’em. The Conftituent Parts of the Animal Body, are, Nerves^ Arteries, Veins, Ljmpha- duSis, Excretorj-veJfels, Fibres, Membranes , Glands, Mujcles, Tendons, Ligaments, Bones and Cartilages ; to thefe, we may add the Hair and Nails, tho’ they have only a Vegi- tative Life. Nerves, are Cylindrical, or Prifinatic Bodies, of ftreight Fibres, which arife from the Medulla Oblongata of the Brain, and the Medulla Spinalis, and terminate in all the Senfitive Parts; They are the immediate Organs of Senfation. The Arteries, are Tubes that arlle in Two Trunks from the Two Ventricles of the Heart, and thence dividing into Branches, diftribute the Blood to every Pare of the Body. Veins, Introduction. XXI Veins, are Tuties to return the Blood from the Extremities of the Arteries to the Heart. L Y M p H ;e-d u c T s, are pellucid Tubes to carry Lymph from all Parts, efpecially the Glands to the V*J* LaStea. Excretor y-V e s s e l s ^ arc either Tubes from Glands to convey the fecreted Fluids to their refpeQive Places, or Veflels from the fmall Guts, to carry^ the Chyle to the Blood-velTels • thele laft, arc call’d Vafi, L,aHea. Fibres, as they appear to the naked Eye, are fimple Threads of the minuted: Blood- veffels or Nerves, or both, which en- ter into the Compofition of every Part. Membranes, are Compagcs’s of Fi- bres, expanded, to cover, or line any other Parr. A Gland, is compos’d of an Artery, Vein , Lymphatic ,- Excretory-duff , and Nerve. The Ufc of Glands is to fecretc Fluids XXll Iktroducton. Fluids from the Blood for divers Ufes. The Artery brings the Blood, the Vein and Lym- phatic return it, the Excretory-du£l con- veys the Matter fecrcted to the Place it is defign’d for, M u s c L E s, are diftinft portions of Fleih, which by contrafting, perform the Motions of the Body, Tendons, are the fame Fibres of which the Mufcles are compos’d, but more clofely conne£l:ed, that they may polTeis lefs fpace in a Limb, and be inferted in Ie(s room into a Bone. Ligaments, are ftrong Membranes, or Bodies of Fibres clofely united, either to bind down the Tendons, or give Origin to the Mufcles, or tye together fuch Bones as have Motion. Bones, are firm Parts to fuftain, and give fhape to the Body. Cartilages or Griftles, are hard, elaftick, fmooth and infenfible : Their Ufe is Introduction. xiii is to cover the Ends of the Bones that have Motion, to prevent their attrition, &c. What it is we call the Hair and Nails, is fufficiently known ; the former feems to be nourifh’d from the Materia Per- ffirabilis^ and the latter from the Reticulum Mucofum betwixt the Cutis and Cuticula.

HE Ufe of the Bones, is, toChaptet give Shape and Stability to the L Body ; to be Levers for the Muf- cles to aft upon, and to defend the more noble Parts from external Injuries. They are in an Embryo Membranous, ’till by degrees they acquire the hardnefs of a Cartilage, and laft of all Bone : This change is not effefted in all parts of the fame Bone at once, but beginning from a middle part) fhoots forth to the extremities. ■ Bones that are void of Motion , when they meet, prefs into each other and form .Sutures, which foon difappear in thofe Bones that meet while they are fofc, tho in fbme they are to be feen in the greateft Age. But the Bones intended for Motion, are prevented from joyning in this manner, by the Cartilages, with which their parts that are oppos’d to each other, are fac’d. The extremities of ' every Bone that is articulated for Motion) or that is not op- B pos’d 2 Of the Bones in general. BOOK pos’d to an other, is tip’d with an Efiphyjis, I. or additional Bone (as may be feen in a Fce:us) which helps to determine its growth and figure. The Filjres of Bones are conne£led like thofe ofVegetables, by fmall Fibres running obliquely from one to another, but are not difpos’d into Lumitiie, - The texture of the Bones when firft form’d , is univerfally loofe and fpongy ; but afterward they become in many places very compaft, which refults in fome mea- fure from the prelTure of the incumbent Parts. In flat Bones, where this prelTure is lealT, the furfaces only are denfe, and the middle fpongy ; but where the prelTure is more confiderable, the whole fubftance of the Bone is one denfe Body, or Table. The Cylindrical Bones being prefs’d moft in their middle by the Bellies ol the Mulcles, are there. very denfe and ftrong, while the extremities dilate into large and fpongy Heads, which is more convenient for their Articulations , gives more room for the Origins, and infertions of Mufcles , and makes their Line of Direftion nearer to a right Angle with that of the Bone. All the Bones, except fo much of the Teeth as are out of the Sockets, are cover’d with a fine Memibrane , upon the Head call’d Pericraniumy ellewhere Periofieum ; this covers every part of each Bone , except where it is -cover’d with % Cartilage , or where Of the Articulations of the Bones. where Mufcles or Ligaments a rife or are Chapter inferred : Its Ufe is to defend the incumbent II* Mufcles from being lacerated in their A6li- ons. Every Cylindrical Bone has a large mid- dle Cavity containing an oily Marrow, and lelTer Cells towards their extremities, con- taining a bloody Marrow ; every one of thefe Cells is lin’d with a fine Membrane* The life of the Marrow is to fupplc the Fibres of the Bones that they may not grow too rigid and britle ; and the Bones themfelves have an advantage from thefe Cavities ; for it has been demonftrated, that their Strength is increas’d by this Strudure, as their Diameters. C H A P. II. Of the Articulation of the Bone s. W E fhall not enumerate all the Names for Articulations which Writers have impos’d; but only mention thofe which feem leaft unnecelTary. Bones are articulated either for gia- hifeft Motion, which is call’d Diarthrop ; oitMron,: or for obfoure, which is nam’d Synchondrop ; ssmchondr** or for no Motion, which is nam’d thropi. B 8 Dl A* 4 Q/ Sutures and Bones of the Head. BOOK Diarthrosis, is of two Sorts, viz,^ Enarthrofis and Ginglimus : The former is Enarthrofis. when the Head of one Bone is receiv’d into Ginglimus. the Cavity of another, which if the Head is round, aind the Cavity deep, is call’d Cotile. Cotile ; but if the one flat and the other eiene. fhallow, GlcM. Thc latter is, when a Bone both receives and is receiv’d, as thofe of the Spine. Synarthrosis, is of two Sorts, eomphofis. Suture, and Gomphofts : The former is when Bones are mutually indented ; the latter, when they are receiv’d like a Nail . in Wood ; of this Sort are the Teeth in their Sockets. Chap. III. Of the Sutures and Bones of the Head. Suture. HOSE Sutures which have proper _£ Names, we will defcribe ; thofe which have not, derive their Names from the Bones they furround, and are known by them. u T u R A Coronalis^ runs a-crols the Head, and joyns, the Frontal to the Parietal Bones. Sutura Sagittalis, joyns the Parietal Bones ; it begins at the Os Occipitis, and is con- of the Sutures and Bones of the Head. 5 continued to the Os Fromis\ in Children Chapter down to the Nofe, the Os Frontis in them Un- being two Bones, and fometimes fo in adult Bodies. Sutura L^mbdoidalis^ joyns the back- part of the two Parietal Bones to the upper part of the Occipital Bone : In this Suture we frequently obferve fmall Bones, call’d OJfa RA Squamofa^ is the wraping of the upper part of the Temporal and Sphe- noidal Bones (which laft is not obferv’d by Authors) over the lower Edges of the Parie- tal Bones. Sutura Tranfverfalis^ joyns the lower Edge of the Frontal Bone to the Ojfa Nafi^ Maxilla Superior^ Vngues\ Plana^ 'Sjpbanoides and Zygoma or Mali. The Scull being thus divided into many Bones, is neither fo fubjeft to Fraftures, nor to have Fraftures fo far extended, as it wou’d have been, were it compos’d of one Bone only. The Ancients not knowing that by this Formation the Bones Offefy’d, more conve- niently imagin’d the Sutures were defign’d for Perfpiration ; and therefore prefenb’d Fontencls upon them for Difeafes of the Brain. But doubtlefs, had this been their Ufe, the Longitudinal Sims wou’d not have been plac’d under the Sagittal Suture, which they thought moft concern’d in this Ope- rationo B j Tm Triquatra. S u T u 6 Of the Sutures and Bones of the Head. Ten of the Bones of the Head compofe the Cr unium to contain the Brain. Thefe we wall firft defcribe. Ossa Bregmatis, are two large Bones almoft equilateral, which compofe the fuperior and lateral Parts of the Crmitm : On the infide they are remarkably imprinted by the Arteries of the Durn. Mater. Os Frontis, makes the fuperior and anterior part of the Cranium ; its lower part corapofcs the upper part of the Orbit of the Eye, in its infide it bears imprefs’d the ex- ternal figure of the two Hemifpheres of the Brain ; fometimes it has a fmall Spine near the Os Ethmoides, and fometimes a Sulcus ; immediately above the Os Ethmoides, in this Bone is a fmall blind Hole through which runs a Vein into the beginning of the Lon, gitudinal Sinus of the Dura Mater ; under the Eye-brows in this Bone are two large Sinujes wich lead into the Nole, and on the upper edge of each Orbit, a fmall Perforati- on, fometimes only a Notch through which run Nerves and an Artery to the Fore- head. Os Ethmoides, Is a fmall Bone about two Inches in circumference, feated in the anterior part of the bafis of the Scull, being almoft furrounded by the laft de- fcrib’d Bone ; it is full of Holes like a Sieve. In its middle arifes a large Procefs nam’d crjfti Qrijla Galli. Dr. Douglafs is of Opinion, That all Spintj Foramen. Sinus* ‘Foramen, Foramina.- of the Sutures and Bones of the Head. y all the Lmim in the Nofe, belong to this Chapter Bone. «I- - Os S?HENO!DEs, is a very irregular Bone, feated in the middle of the Bafis of the Cram- utTij bounded on its fore-part by the Frontal and Ethmoidal Bones, laterally by the Parie- tal and Temporal Bones, and backwards by the Fetrofum and Occipital Bone. In its in- fide next the Brain is a Cavity, nam’d Sella s=iii Tiirc« Turcica, which is bounded by Four Procef-'*’ fes, call’d Clinoides. On the outfide of the pro». ci:- Scull adjoyning to the Upper Jaw, are Two™***"' Procelles of this Bone on each fide, nam’d fterygoides, from which ProcelTes arifeOne Proc.

At the in- fide of the Bafis of the T wo anterior Clinoid ProcelTes are Two round Holes, which are the Firft Foramina of the Scull ; almoft under ^ , thefe laterally are Two irregular Slits, nam’d Foramina lacera, or the Second Foramina of the Scull; and under thele are Two round Holes, which are the Third Foramina ; about half an Inch nearer the Occiput, are Two " more of an oval figure, which are the Fourth Foramina ; and a Straw’s breadth farther Two, call’d the Fifth Foramina.

Of the Muscles in general. H E Mufcles are fo many mov- Chapter I ing Powers, or Cords, applyM to I. i perform the Motions of the feve- ral Parts : Which they do by con- trafting their Length ; and thereby bring the Parts to which they are fix’d nearer to- gether. The immovable', or leaft mov’d Point any Mufcle is fix’d to, is call’d its Ori- gin, and the other its Infertion. The Power or Force of any Mufcle, is to be computed by its number of Fibres, and the manner of its Infertion. For the Strength of each Mufcle is as the number of its Fi- bres ; and the Power with which it afis up- on the mov’d Limb, is as the diftance of its Infertion from the Center of Motion, and the nearnefs of its Direftion to a Right An- gle with that of the Bone mov’d. The quick- refs or quantity of Motion in a Limb, will be as the length of the Fibres of the mov- ing Mufcle, and the nearnefs of Infertion to the Center of Motion. In thefe Cafes, D 4 whatever Of the Mufcies in general. BOOK whatever is gain’d in velocity, is loft in ft. ftrength ; and fo the contrary. From this it appears, That a Mufcle of any Figure may be made fit either for ftrength or quicknefs of Motion by its In- fertion : For a Mufcle of long Fibres may caufe a flow and ftrong Motion by an Infer- tion diftant from the Center of Motion ; and a periiform Mufcle, or any other of ftiort Fibres, may caufe a quick Motion from a near Infertion. Thefe Things being Confider’d , it will not be difficult to account for the great diffe^ rence we obferve in the Aftivity or Strength of Men or Brutes, or for one Man’s being ftronger or nimbler than another of greater Bulk. It muft alfo be confider’d in Calculating the ftrength of any Mufcle, thar its force as it contraQs in its length, decreafes in the fame, pr near the fame, proportion. The Flexors have neverthelefs the fame, or near the fame, power in all Pofitipns, ’till they bring the Limb mov’d to Right Angles with their own Direftions ; for the advantage of their Di- r eel ion increafes; in the fame, or near the fame , proportion that their power de- creafes. In the Extenfors of the large Joynts, as the Thigh and Arm, there are feveral Muft cle^ imploy’d, which are lb contriv’d, that as the firll Movers decreafe in power by ap- proaching to the fame Direflion with the ■ ' • ' ' of the Membranes of the Mujcles, 4 ^ Eone mov’d, fome other Mufcle begins toChupter aft, which increafes its power in the fame II- degree, by the advantage of a more convc- nient Direftion, and greater bulk. Hence refults that great Regularity that there is in the Motions of the feveral Parts. We may alfo obferve, That the Mufcles >vhich are in continual Motion, as thofe of the Thoraxy and thofe which fuftain great Weights, are inferted at Right Angles, while other Mufcles of lefs-confequence have left advantageous Infertions. Chap. II. Of the Membranes of Muscles. M EMBRANjE Musculorum. All the External Mufcles are either cover!d with a ftrong tendinous expanfion, or with a thin lax Membrane : Tlie former is either the flat Tendon of fome other Muf- cle or Mufcles, as may be obferv’d upon the Abdomen and Loyns, or a Fafcia detach’d from the Tendons of other Mufcles, as may be feen in the Limbs : Or not deriv’d from any, as we may obferve upon the InfrA- ff inati of the ScapuU.

It may be obfcrv’d, tho’ fo much of this Mufcle as is inferted'flefhy, runs obliquely upwards, yet the middle and lower part is direfted tranfverfe and downwards, and be- fide the Tendon which it unites with the Obliqi4ii6 defcendtnsj it detaches another to be inferred with the Tranfverfdis under the Pyramidalis, arifes from the Os Pu^ his^ and is inferred into xhQ Linen albmhout three or four Inches bel6w the Navel : This with its fellow are often w^anting. - Rectus, arifes fomewhat tendinous from the Os Pubis ; but flefliy when the Py- rnmiddes are wanting, and is inferred into the lower part of the Sternum near the CnrtL Ugo Enfiformis. This Mufcle is divided into four or five portions by tranfverfe tendinous Interfeftions, that it might not prefs the contain’d Parts only in one Place ; but thefe Interfeftions are chiefly above the Navel, a larger Belly being convenient below to fup^ port the Vtfeera.

This Gland has its Saliva promoted by the Motions of the Lower Jaw. If the Duft of this Gland be divided by an external Wound, the Saliva will flow cut on the Cheek, unlefs a convenient Perforati- on be made into the Mouth, and then the external Wound may be heal’d. Mv.Fer^e^ while I was his Apprentice, had Two Patients with this Gland Ulcerated , from which there was a conftant effufion of Saliva^ ’till he confum’d the greateft part of the Gland with Red Mercury Rrectuhate^ and then it heal’d with little trouble.

It was a true Schirous, and weigh’d Twenty ; fix Ounces. In a Man which we Differed, we found a quantity of Pus near this Gland, and a Bun- dle of Matter not unlike Hair, as large as an Hen’s Egg. A Woman which was my Mafter’s Pati- - ent in the Hofpital, had a great number of Chalk Stones in this Gland. The like Con- ' cretions we have met with in other Places in Bodies which we have Differed. Sublingualis, is a fmall Gland fituated under the Tongue between the Jaw and the Cerataglofus j^^ufcle ; it fends its Duel into that of the Maxillaris inferior.

They are comprefs’d by the Tongue, and the Aliment, when the former raifes the latter over its Root , and thereby opportunely emit their Saliva to lubri- cate the Food for its eafierdefcent thro’ the Pharynx. A Schirous Tumor of either of thele Glands, is a common Difeafe, and ia admits of no Remedy but Extirpation : Yet it mull: not be perform’d upon the whole Gland, but fo much of it as is become fupernaturally eminent ; becaufe that wou’d render it un- fit for the afore- mention’d Ufes.

' In Dropfies of the Abdomen^ and in Per- fons who from any other Caufe, have dy’d Tabid, we have found it rotten and decay’d, and not feldom, the Guts adhering to one ' another : But whether thefe Adhefions pro- ceed from the OmentunPs ceafing to perforin its Office, or from the Periftaltick Motion of the Guts being long difeontinu’d thro’ Ab- ftinence, or both, we think not neceiTary to Difpute. Ductus Alimentalis, is the OEfophxgm^ Stomach, and Guts, viz. Duode- num^ Jejunum^ Ilium^ Colon^ Cdictim or Apen- dicuLi Vermiformis^ and Return. OEs o p H A G u s or Gullet,, is the Begin- ning of the Alimentary Duft ; its upper part is wide and open, fpread behind the Tongue to receive the mafiicated Aliment ; it begins from the Bafis of the Scull, near the Procejfus Pterygoides of the Sphenoidal-bone, and is ^ call’d by fome Anatomifts Mufculus Pterygo- pharyngeus ; this defeending becomes round, and is call’d Vaginalis GuU ; it runs from the Tongue clofe to the Spine, into and thro’ the Thorax on the left fide under the great Artery, then piercing the Diaphragm, im- mcdiatelv enters the Stomach. It is com- H j pos’d I01 Of the Omentum^ DuHus BOOK pos’d of a thin outer Coat, which is no more ill. than a proper Membrane to the middle or Mufcular Coat. The middle Coat, is com- pos’d of a Spiral Order of Mufcular Fibres," abundantly thicker than the fame Coat in | the Inteftines ; both becaufe this has no fo- j reign power to alTift it, as the Guts have, and j becaufe it is neceflary the Food ihou’d make I a fhorter flay here than there. The inner Coat, is a pretty fmooth Membrane, befet with many Glands, which fecrerc a Mu- cilaginous Matter, both to defend the Membrane, and render the defcent of the Aliment left difficult. Ventriculus, the Stomach, is fitua- ted under the left fide of the Diaphragm, its left fide touching the Splene, and its right cover’d by the thin Edge of the Liver ; its ^ figure exactly refembles the pouch of a Bag- pipe, its left End being moft capacious, the upper Side concave, and the lower convex ; it has two Orifices, both on its upper part ; the left (thro’ which the Aliment palfes into Kardia. the Stomach) is nam’d Kjrdia ; and the right (tiiro’ which it is convey’d out of the Sto- pyiorus m^ich into the Duodenum') is nam’d Pylorus, where there is a circular Valve to hinder the return of Aliment out of the Gut. Iffie Coats of the Stomach, are but Three; the external Membranous, the mid- dle Mufcular, whofe Fibres are chiefly Lon- gitudinal and Circular, the inner Membra- nous, and befet with Glands, which lepa- ratc Alimentali^s and Mefentery. 105 irate that Macas, which is falfely call’d Mem- Chapter ^l?rAP7a Quart A or Villofa.

Jejunum, is fo call’d from its being found for the moft part empty ; it’s fituated in the Regio Umbilicalis, and makes fome- what more than a third part of the fmall Guts. It may be known from the follow- ing Gut, by obferving its Coats, which are a fmall Matter thinner, and left pale.

This Gut has fch dom any thing in it. The Beginning of the Colon^ is vulgarly call’d .the blind Gut, it feeming to have but one entrance when the Valves are fliut againfi: th^ limn. And we are apt to think, Modern Anatomifis have made a Miftake in palling the Jpendicula Venniformis^ Cacum ; feeing they reckon it among the great Guts. In Dogs, Cats, and Squirrils it is very large : i\nd feme Fifin have ’em in great number; we have counted in a Mackarell, above 150. R £ c T u M, is the Continuation of the Co- lon riiro’ the Pekju to the Anus. Th.e Guts have the fame Coats with the Stomachi ; the Fibres of their middle or Mufi cuiar Coat, are either Circular, Spiral, or Longitudinai ; of the latter, but very few. The great Guts, have at equal diflances a fircight Membrane on their cutfide running their whole 'length, call’d Ligaments; thefe Idgaments draw the Guts into fmall Sacculi. The leffer Guts, have at very fmall diftances Semilunar Valves plac’d oppofite to the In- terdices of each other ; thefe prevent the Aiinient from palling too fpeedily. But Brutes have Alimentalm and Mefentery. 105 have ’em not : becaufe they are not necef- Chapter fary to an Horizontal Pofture. At the En- V. trance of the Ilium into the Colon^ are Two very large Valves, which effeftually hinder the regrefs of the Faces into the Colon ; the other Valves in the Colon^ are plac’d oppo- fite (but not in the fame Plane) to each o- ther, and make with their anterior Edges an Equilateral Triangle ; but as the Gut ap- proaches the AnuSy they become lefs re- markable, and fewer in number. All the Guts have in their inner Mem- viands, brane an almoft infinite number of invifible Glands, which feparate the Mucus that de- fends the Guts. Thefe Glands will, fomc of ’em efpecially in the large Guts, appear to the naked Eye when they are difeas’d, and are then call’d GUnduU Pjeriana, The length of the Guts to that of the Body, is as Five to One, in a middle-fiz’d Man ; in taller Men, the proportion is lefs, - and in fmall Men greater. Mesentery, is a Membrane begin- ning loofely upon the Loyns, and is thence producM to all the Guts ; It preferves the Jejunum and Ilium from twilling in their Pe- rifialtick or Vermiciilar Motion, and con- fines the reft to their Places ; it fuftains all the Velfels going to and from the Guts, z>iz.

The Gall-bladder, is a receptacle of Bile, feated in the hollow-fide of the Li- ver ; it is compos’d of one denfe Coat not Mufcular, and cover’d with another, which is common to it and the Liver. The Excretory Dufts of the Liver leading to the Gall-Bladder, are, the CyJHhepatict^ which pafs in great number into it, and fo fmall as not to be feen by the naked Eye : From the Gall-Bladder towards the Diwde- ntim^ runs a Duft call’d Cyjlicus; and from the Liver to thisDuQ:, one call’d Hepaticus^ DuausHe. which carries off the Gall this way, when the Gall-Bladder is full ; then the Ductus Cyfticus and Hepaticus being united, com- mence Duclus communis Choledochus^ which enters the Duodenum obliquely about Four inches below its Beginning.

' The Situation of the Gall-Bladder is very remarkable ; for it being feated againft the Duodenum^ it will have its Fluid prefs’d out by the Aliment paffing thro’ that Gut, and confequently, not only at a right Time, but alfo in due Proportion ; becaufe the greater the quantity of Aliment is, the greater will be the Compreffion ; and fo the contrary. Pancrea s, the S^vect-Brede^ is a large Gland of the Salivary-kind, lying a-crofs the upper and back-part of the Ahdomer^^ along- fide the Duodenum^ it is what the Antients call’d a Conglomerate Gland, appearing fo (without DilTettion) to the naked Eye ; it lias a fhort Excretory Duft, not more than half fo large as a Crow-quill, (tho’ it is com- monly painted as large as the Ducius com- munis Choledochus') which enters the Duode- num very near the Bile DuT, and not fel- dom, together with it. The Juice of this Gland, together with the Bile, ferves to attenuate the fluid Par- ticles of the digefted Aliment, and render it fit for the Lafteals. The Splene, is feated in the left Hj- pochondrium , immediately under the Dia- phragm, and above the Kidney , between the Stomach and the Ribs ; it is fupported by the fub-contain’d Parts, and often fix’d to its Place by a fmall adhefion to the Fento- neum * Pancr Cits and splene. « 10 «^ mum\ it is alfo corinefted to the Omentum^ as Chapter has been obferv’d. The Figure of it is a fort VI. of deprefs’d Oval, near twice as long as broad, and almoft twice as broad as thick : Sometimes it is divided into Lobules, but for the moft part, has only one or two fmall FilTures on its Edge, and fometimes none ; in its Colour, it refembles Caft-Iron. The co«s. inner Texture is Veficular, like the Pm'i; thefe Cells have in ’em fmall Glands and grumous Blood. This Bowel has no Excre- tory DuQ:, that we can difcovcr, and all the Ufe that we can affian to it, is to retard the Blood in. its courfe to the Liver, that it may there arrive vifcid and languid enough for the Secretion of fo thick a Fluid as is the Bile. The Liver, ordinarily weighs, in a O^ierra- middle-fizM Man, about Three • Pounds, Twelve Ounces, the Three Ounces, and the Splene Fourteen Ounces. The Splene, we have taken out of a Dog, without any remarkable inconveni- ence to him. We have found Three Splenes in a Wo- man that was executed. We have feen a difeas’d Liver in a Man, that weigh’d Fourteen Pounds, Four Ounces. In a Boy but Nine Years old, that dy’d Hydropick, we found the Liver full of Hy- dmdsy and with Cyfts of Hydatids adhering to iio Of the Liver ^ Gall-Bladder^ Sec. ’I BOOK to it, M^hich together weigh’d Seven Pounds, III- One Ounce and a Half, tho’ feveral Pints of $ Water had been let out of it before. The' r j Splene, in the fame Boy, together with Hy~ jil datids contain’d in its Membrane, weigh’d Three Pounds. In a Man, we have found a difeas’d Splene weighing Five Pounds, Two Ounces. In an old Man Six Foot high, we have found a found Liver, weighing no more than Twenty-eight Ounces, and the Splene Ten Ounces. In a Man that had been affliiled with a Dropfy, and cur’d,. we have found a Poly- pus almofl: filling the large Branches of the Porta in the Liver, and a Stone between the Liver and Gall-Bladder, larger than a Nut- meg. In a Man that dy’d of a Jaundice, wc found the Ductus communis Choledochus, con- ftricted by a Schirous Pancreas. The Gall- Bladder was extended to the fize of a Goofe- Egg, and all the Dufts to twice their na- tural bignefs. This Cafe afforded a beauti- ful fight of the Cyjlihepatick Du£bs to the naked Eye. We have met with' an Obftru£l;ion in the Ductus Syflicus, without any remarkable in- convenience ; the Bile being in that Cafe,' carry’d'off thro’ the Ductus Hepaticus with- out entering the Gall-Bladder.

The Rca- fon why Nature has macle ufe of a Vein inftead of an Artery in this place is, becaufe the Blood in the Arteries fo near the Heart, is too rapid to have fo vifcid a Fluid feparated from it as the Bile.

Befides thefe Ufes, we may rcafonably conjefturc, That fome of the Humour con- tain’d in the Amnion^ is made ufe of for the Nourifh- i ijo Of the Fcetm in the Womb.

The Placenta, or Womb-Liver, is a Mafs of Blood-VelTcls feated on the outfidc of the Chorion, being compos’d of the ex- treme Branches of the Umbilical-Vein and Arteries,which arc for the compofitiorwof this Part divided into exceeding fmall Branches, that the feparation of ’em from theMenftrual VclTels of the Womb at the Birth, may not be attended with a flux of Blood, fatal to the Mother.

Near the entrance of this Veflcl into the Porta, there goes out rua.Tcno- the Ductuf Venohes to the great Trunk of the Cava, and carries about a third part of the Blood which is brought by the Umbilical- Vein that way, into the Cava, while the reft circulates with the Blood of the Porta.

The over- plus of Blood brouglit from the Mother to the Fcetfu by the Umbilical- Vein, is return’d to the Mother by Two Veffels '*"’'**’ arifing from the Internal Iliac Arteries, call’d Umbilical Arteries. Thefe Veffels pafs by the outfides of the Bladder direftly to the Na- vel and PUcentA and together with thefe, there runs a fmall Du£l, call’d VrAchus^ from viachu». the Top of the Bladder thro’ the Navel into a Membranous Bag, feated oppcfite to the PlAcerjtA between the MemhrAnA Chorion and Amnion^ nam’d Allantois^ or rather Membrana allantois, IjrinariA, Thefe Umbilical Veffels from the Navel to the Placenta^ are about Two Foot long, which was neceffary, that the Fc^tu^ might have room to move without tearing them or the Placenta from the Vterus.

BOOK thro’ the right Ventricle, as after the Birth» while the Blood from the Defcending Cava, paffes thro’ the right Auricle and Ventricle into the Pulmonary Artery, and thence in- to the Aorta thro’ a Du£t betwixt that and Ar- the Pulmonary Artery, call’d Ductus Arterio- teriofus. while a fmall portion of the Blood thrown into the Pulmonary Artery, palfes thro’ the Lungs to keep open the Pulmonary Velfels. Thus both Ventricles are employ’d in driv- ing the Blood thro’ the Aorta to all Parts of the Feetus and to the Mother : But after the Birth, the Blood being only drove from the Aorta thro’ the Fwtus, one Ventricle becomes fufficient ; while the other is imploy’d in driving the Blood thro’ the Lungs, the Duc- tus Arteriofus being obftrufted from the al- teration of its Poiition, which happens to it from the raifing of the Aorta by the Lungs, when they become inflated. The Blood being thus drove into the Lungs, in its re- turn it fliuts the Valve of the Foramen Ovale again the Foramen, to whofe fides it foon ad- heres, .and flops up this Paffage. The Ductus Arteriofus or Duttus Arteriofus in Ligamentum verfus, is fddom to be obferv’d in adult Bo- dies, but the figure of the Foramen Ovale is never obliterated.- Among the Obfervations which I made, when I firfl apply’d myfdf to the Diflefiion of Human Bodies, there are frequent Ac- counts of the Foramen Ovale open in Adults; but I find fince that I miflook the Oflum Ve- I narum Of the Foetm in the Womb. 1 7 :j narum Coronariarumy for this Foramen.

But the reafon why Am- phibious Animals can live longer without breathing, than other Animals that have Lungs, is the largenefs of their Veins, which receive the greateft part of the Blood when they do not breath , and prevent the Lungs being overcharg’d ; for all thefe Animals can refrain longeft from breathing, when their Blood is leaft expanded with Heat, or their Veins moft dilated. All the Parts of a Foetus are Ibfter than in Adults ; -the Head and the Cavity of the Jb. domen are remarkably large, and all the Parts contain’d in both, are proportionably bigger than afterwards, efpecially the GlanduU Re- nales. ■ The Organs of Hearing and Sight, are wonderfully perfeft ; and the Gland Thy- mus at the time of the Birth, is at the big- eft ftatc, and all the Glands, particullarly thofe which accompany the Lymphatics , bear a much greater proportion to the otlier Parrs, tlian they do in Bodies full-grown.
