They may moreover think that hem an exad deEription ol the feveral parts of his Body, raoir, if not all Vef- lels and Organs being larger confiderably in him, A z than than in ocher Creatures, a great light into the true ufes or parrs might be had. Now Sir, I muft dehre you to inform that Ho- nourable Society, for whom you dehgn thefe fol- lowingNotes, and of whom you are a Member, with the Reaions why I cannot anfwer fuch great expectations. My want of Opcick Glaffes, and of other helps for curious Obiervations were coniide- rable. Moreover the Circiim (lances of time and place were unfortunate 5 for the Booth wherein the Ele- phant was kept, took fire about Three a Clock in the morning, on Friday the 17th of June ^ upon this the City being alarm'd, multitudes were ga- tl.c.ed about the place : And when the fire was extinguiflaed every one endeavoured to procure fome part of the Elephant, few ot them having feen him living, by reaion of the great rates put upon the figfit of him. To prevemt his being taken away by the rnulticude , the M inager, Mr. IVdkins^ procured a File of Mufqueteers to guard him, till lie (lioiild build a filed where he might fe- curely disjaiut him, in order to the making of a Skeleton; This heoot hninied at Seven a Clock at Nidht, and about Eight I heard of his dengn. Be- ing delirous to inform my (elf in the EiuCture of the Elephant, ' made (earch for him, and having found rrr _ — found him I proffered my lervice to him ; of which when he accepted, I endeavoured to perliiade him to difcharse fome Butchers which he had in a rea- , dineis to order the Elephant after their way, and to leave the whole nianagemeqc of the matter to me, and to fuch as I thought fit to employ, de- figning a general dilfedtion, and that the Icons of each part lliould be taken in order by fome Paint- ers, \T ich whom upon this occauon I could prevail : But my endeavours proved fruitleis, becaule that about Ten a Clock that night, when we went to the fhed, to find what condition the Elephant was in, he emitted very noifom fleams. Thele made the Manager fear (the fhed being very near the Council-Chamber, and the Cufl:om-Houfe,j that the Ld. Lt. or Ld. Mayor would order it to be ta- ken away as a nuyfrnce, and that lo in all proba- bility it llioula be lofi, and that perhaps he him- lelf ilioiild be piinifhed for fuffering it to be there. When 1 coniidered, that in caie he did not difpofe ofh im that Night, the next Day being Saturday^ I Osould be able to accomplifii but a fimall part of whnr I defgned, and that it would be both charge- able and difficult to preierve him from the rabble till Monday^ and that then the fcink would be alto- gether intolerable, if it fiiouldencreafe in propor- tion to what it had done that day. I coniented to have the bufinefs done that night, and for expedi- tions lake, to make ufe of the Butchers as AlTillants, but fo as to be dire(5led by my felf m every thina : But their forwardnels to cut and llafli what came firO: in their way,, and their imrulinels whchal did hinder me from making feveral Remarks which otherwiie I would have made: Thus the phant was disjointed by Candledight. Some narcs were burnt, m.oft of thole that were not, w^ere more or lefs defac'd by being parboiled. This may fatisfie the R. S', how didicuit it was to give a la- tisfadlory Anatomncal Account of the Elephant , and that the following fender one is given to fliew my readinels to ferve them, and my Obedience to your ComiTiands. I fhallnot trouble you with aRcpetidon of what has been laid of the Elephant by ^Pliny^ Gefner^ Ta= rvernier^ and others, being very little, if any way, inftrublive to any defirous to underftand the Ana- tomay of that Creature, but (Iiail faithfully, and as plainly as I can, acquaint you with what occur- red remarkable to me, upon a view of the leveral parts of his Body, and iliall add only lome con- jectures of miy oivii concerning the ufes of fome parts- derived from their (IruCtore. I fliall begin wdth the Cntkula^ (of whicli I keep a piece which was railed by the Fire from a part of ( 7 ) the Cutis y on which the Elephant was found lying, and which therefore was not defac'd) when I ex- amined this, I found it covered all over with a Erange fort of Scab, in many places refembling old Warts, deeply j^gg'd, and the carnous Fibres of the Mufcles ot Beef, when much boiled, and tranlverily cut, but of a dirty tawny Colour. Thele Scabs ( if I may fo call them J both flit and cut, lookt like Oiort pieces of Whalebone. They did fo firmly flick to the Cuticula, that I could not pull them from it, nor the parts of which they confifl:- ed (though they were much divided^ from one a- nocher, without tearing it. Andytt t\\Q Cut icuU was much tougher and thicker than*any that 1 have feen. The length of thefe Scabs was in fome -f or i but in other pi ices not above T^or4-r of an Inch. The caufe oi wliich difference I take to be the Ele- phants wearing, by rubbing or lying, lome parts of them, whilfl: others were flight ly or not at all W’orn. I could find but very few Hairs without this fcab, but many within, and even with it. The Elephants inclinations to Itch, and to rub himlelf asain'l what- ever came in his way, kept thoie Hairs that were even with the outnde of the aforelaid Icab, from appearing of any conficlerable length. The hard- ( 8 ) neis of the fcab by keeping the Roots of the Hairs faft, did very much contribute to their wearing on the outfiiie, as well as to their preiervation on that within. The length of the Hairs for the mofcparc was equal to that of the Scabs. 7heHair. The Hair in the when clivelfe.^ F icshji= ticula^ were DLirrerous, and many ol ue- .were confiderablv ftiffer and thirlar ■ n ne ■ ■■ H:ies Oi a Hog. They were black, ar ^ aviu aiy as were found in the Cuticula^ when \/\ * reF lorn to j («- tisj were plainly covered hi thin branes, from the extrerrhiy u> rhe Boots an the Cuticula. Thele (withfubrrfiiuou -n- batter ment) I take to be the linings to peculiar which by the heat of the Fire were fepara ted from them, as the Cuticula was fi onri the Cutis. In rhele duclus the Hairs were manifeilly planted. Now feeing that dole about the Pxots of Hairs, as well as on the Pores, near which there is no Hair, a dew may be difcerned foon after fweac is wiped away. I take it to be reafonable ro think, that there are two iorts of Pores in the skins of Animals. One lmall,deligned altogether for the (eparanon or fiich Liquors and Vapoius, as areuflially thrown oh by iofenfible Perlpiration and Sweat. The other to contain and nourifli Hairs,- for at the bottom of each of thefe duclus there appeared to the naked Eye imali (?) fmallGlandules when the5/iin was divided to the eX" tremityof the roots. Thefe I fuppoie to be the ^landuU miliares^ obferv’d by the moft accurate Ana- tom ifts, Se^mor ^ 2LY\d Dr, Steno^ in their ftni(5ture oi the Cutis. Theie probably feparate from the mais ot Blood an excrementitious matter, fit for the nourifhment of the Hairs , and what is not fpent in that, is ( 1 luppofe) caft out between the Hairs and the aforementioned thin Membranes, which, upon that account, may be properly cal- led Lymphatdudls,- and fo likewife may the Imal- ler foi t, (of which more anon) and each of them a proper Vas excretorium to a Glandula Mdiarts, The Hairs^which came out of the Skin, and which were in the Cuticula^ were from the end of the root to the Cuticula in length between ~ and f of an Inch. The outw 2 .r d fuper fide s of thetwfh, freed from Cut^, the Cuticula, was very uneven , by reaion of a vafl: number of Pyramidal papdU, about the bignels of fnall Pins heads : To fit each of thefe there were cavities in the Cuticula. Thefe paplllx were probably pores, being to the fight like thofe that a hidden Cold produces in our Skins, and which unquestionably are Inch. Now if it be granted, that in Brutes there is an infenfible Perfpiration (which all rational men B that ( 10 ) that fees them fweat will allow , forarmuch as what is by that call off, is not Co grofs a Body as Sweat,) and if their infenfible difcharge be grant- ed proportionable to that of a man ; it will follow, that the Elephant being a Creature of extraordina- ry bulk, muH: have very many pores, and very large ones too, fuch as may be difcerned by the naked Eye, when we find them to be lb even in Men, in the Palms efpecially of the Hands, and in them all other Velfels are proportionably lels than they were in the Elephant. I lay, that the pores mull: be both numerous and large, for the ule aforefaid, elpecial- ly if we may confide in SanSlorlm his Statical Objer- yations 3. nuns infenfibly perfpiringin a Winters day 50 Ounces, and upwards, which is fomwhat more than a 5 4th part of an ordinary mans weight, which 1 take to be about 1 70 /. (and upon fiach meaning himlelf, I fiippole him to have made his Experiments,) and allow the Elephant to perlpire proportionably, we will find that his daily infen- fible evacuation will amount to very near 9 5 /. if we may believe fome that has feen the Elephant put on Shipboard, and taken off,that faid he weigh- ed 2t Tuns or 5000 /. of which 93/. is about a 54th part. Though 1 am not forward to believe, what I have at feveral times been told, as to his weight, nor affured that hisTranfpiration was pro - pcrtia- prn porcionable to that of a man, becaufe of the out- tvard fcab, which might bar it j yet that he did much tranfpire / believe, from the vivacity of his fpeciesy and have together with many Arguments for per- fpiration in general, one in particular to alledge for the great necelTity of it in this Animal, and that is this, his blood and Hefli did extraordinarily a^ bound with an urinous Salt, which made the mals of humours extraordinary active, and confequently capable of making their way through the frnalleft palTages, the pungency of the Salt not a little irrita- ting the pores to an excretion. I fuppofe moreover that this Salt ought to be necelfarily and continually call off with ferofities, to prevent difeafes confe- quent Co too great a quantity of Volatile Salt in the Body.' Why the exorbitancy of this fort of Salt, as well as that of gi^xcdMarmeSaltmScorbutickPevConSy fhould not caufe many di lempers, (though few of fuch may be known to the Inhabitants of our cold Climates, jl cannot guefs; but chat he did fb abound in an Urinous Salt, did appear not only from the urinous effluVta which fo aflfedled my Noilrils that i was fcarce able to endure them ; but alfo from the finarting which his blood occafioned, (contrary to what I ever obferv'd in that of other Creatures} lighting on a cutt which I accidentally at that time receiv’d in one of my Fingers. The difference be- B z tween f tween the pungency of the Salt in this Blood, and that in ftale Urine was fuch, that the latter uliially in a little time ceafes to Simulate a tender part kept fteept in it, whereas the Former did make my Finger r all that night, and the next day whilft embrued in ! it continually fmart. But more efpecially it appear- ed from the taft of his Fiefh when drelTed on the ^1; Coals, before a fire, or fri’d, (boiling in Water took it clear away) which was, as near as I can guefs,like that oflean Beef feafon'd with Salt of Flartshorn. It is not only probable therefore that the Ele- phant did inf^niibly perlpire much, but alfb that thofe Pyramidal Tajj'dU were the paffages through which he did traiifpire, nothing except them and the places of the Hairs appearing any way like pores. fub- When the Cutis was cut through, as far common- ly as the roots of theHairs reach'd, it was 1 ike the cal- lous or horny part of Brawn ; but the inner part was very glandulous with a little fat interfpers’d. •'ajjities Cutis before it dried was in fome places I “ Inch thick,and in other places not above an Inch^ and in others fomwhat lefs. I could fine! no cutaneous Vefiel of any remark- able bignefs, and but very few fmall ones, mnku- 1 made fearch for the Tanniculm carnofus, but f' found none. / was the more diligent in my fearch defutt. becaufe that I underftood it was iifual with the 1 ' (is) the Elephant to kill the Flies which lighted on the cracks in his Skin, and tormented him ; and this he did by bringing the (ides of the cracks dole toge- ther of a Hidden, which I thought to be performed by that cutaneous Mufcle, meaning the aforefaid Tanniculus carnofus^ but nothing like it appearing, I concluded that what I ftippofed ought to have been done by that Mufcle, was in this Animal done by putting himfelf fuddenly in a pofture to wrinkle the skin ot that (ide that was attack’d by the Flies, . and this to be done by bending his body that way, by which means what was before ftreight for him, being now too -full, the fides of the cracks were forced dole together. Sc thus the Flies were bruisM. There was no Memhrana adtpofa to be ieen about Defuir& him, neither was there inwardly or outwardly, eX' cept a little in the Terineum^ any appearance ol fat ; fa. but infteadof the two laft mentioned integuments, there was a very flrong nervous Merribrane, ob- liquely defce iding from the Spines dorfi to the Ster- Mmbra-- nunij and the linea alba. This Membrane was very cough, and very near as hard to be cut as Whale-' bone of the fame thicknefs ^ which all along the back-bone was about 7 of an Inch 5 but the nearer the end 1 tried it the thinner I found it. Tl sis Mem- brane leem’d to terminate in the Imea aiba^ as the tendons of the Mufcies of the abdomen ufually do. The Tax- "wax^ MufcuU duo Re- traBores Tenis^ (H) The nervous Fibres of which this Membrane was made, were very diftinguifliable, and might eafily be feparated for their whole length. 1 have nothing to fay as to its Origin, unlefs it proceeded from the dura Mater. This doubdefs was delign^d to ftreng- then this Creature, and perhaps that the weight of the Fifcera contain d in the Abdomen^ fhould not di- dend the ^eritoneum^ and the Mufcles adjoining, lb as to let them hang lower than was convenient. The Ligament, com monlycairdTaxwax,reach*d from the Head, to which it grew, to about the 1 3 th ! i; Membrane, which was faftened to them in no place, but at the emulgent VefTels* When this was taken off^ each of the Kidneys was found to confift of fix Lobes, The Cavity iifually found in other Kidneys, called the Tehls^ here was wanting. I found the Ureter divided into 6 parts, one for each Lobe, each of them (as near as I can guefs ) of equal Diameter with the Ureter itlelf. Thele went into their refpe6tive Lobes, about an inch before their arterial fubftance terminated. There were no CaruncuU ^apillares , neither could I find any thing that made the ma»ner of fepara- ting the Urine , more intelligible than formerly it was. The Ureter was ito wider than that of an Ox ^ it had nothing peculiarly remarkable, except its difproporti- on to moft of the other parts of the Body. The Vejica Urinaria was much of the fame fize with an Oxes Bladder, but much ftronger, having thicker Fibres. The Fend prdparantes ^^ere large. I divided that which was inferred into the emulgent, lengthwife ; and, within a little more than an inch to its infertion, I found many nbya Psdiitaria jinterior. { 30 ) _ on the Membrancwas about ^ of an Inch. The lower Jaw of thisBeafl, didrefemblc that of a Hog, the moft of any thing. His Tongue was fomewhat bigger than that of an Ox, and plac’d after the ufual manner. But this it had peculiar in it, that the paffage to the Ventricle was through it 5 for there was a hole near tiae Root of it, and exa(fll7 in the middle of that part. Which hole was die beginning of the Mfo^hagus 5 there was no communication between this and the pafCige into the Lungs, contrary to what we may obferve in Men, in all Qua- drupeds and Fowl that ever I had an opper- tunity to difTecft. For the Membrana Pituita- ria Anterior, reach’d to the very Root of tl e Tongue below the JEfo^hagus’, *Uid fo quite Rop’d the palTage of the Air into the Mouth, From whence we mar conclude, that he could not utter any voice by the mouth, and but little by the trunk or nofe. The former Memhrana Pituitaria had ma- ny paRages for tlae ufually feparated there. There was between tht: end of the Probofeis and the Larinx a MembrdnaP ituitaria fOfterior , which had ver,v many of the fame fort of duRus. The ( 31 ) The Probofcis was only a nofe prolong’d, where it was feparated from the Forehead, the fubftance of it look’d exadly like that of a Neats- tongue flit : the fleOi of it being cti- rioiifly interlarded. Where the fire had en- ter'd upon it, I could diflindrly perceive three Orders of Fibres 5 one obliquely and fpiralLy defcending 5 another fpirally but crofwife de- fcendingf the third were ftreight Fibrcf. Several of the notions of bis Frohofcls might ProhofciSTs be perform’d by the aforementioned three diflinc^t Series’s of Mufcular Fibres. As its contraction , motion up , or down, to the right, or to the left : But by what means he was able at pleafure, to Ihoot it out from, a foot upon any fuddain occafion to five foot long ^ and that with extraordinary force, I cannot clearly perceive. This fort of motion feems to require a particular Theory, being very diiFerent from the other motions in the Body of this, and of other Animals 5 for to me all Mufcular motion feems to be by a. con- traction of Fibres, even when the extention of a Part is defign’d. In which cafe the Bones of the Parts are drawn, and kept direc 5 tly one before another , by the contraeffion, of fomc of the Mufcles.. Now ( 32 ) Now we do not find any part without a Bone, ( except this ) that is Spontaneoufly protruded or prolong’d, and fo kept for fome time. Some may Imagine that the Tongue is mov’d after this manner ^ but tis certain, that the Mu fail geneoglojfus by the help of the My logic jfus draws the root of the Tongue, and confequently the Os Hyoides forward, that is, to the fore part of the Maxilla hiferior where they are inferred , and that fo it is that the Tongue is protended. The onely way that I can guefs this moti- on to be perform’d is by circularFibres5 feeing that there was no Bone towards the end of it, beyond the upper Jaw, whichmight be,^ Sta- bilimentum to Mufcles that might pull it for- wards 5 as the Geneoglojfus does the Tongue, by drawing the Bafis of it towards the middle of the Maxilla inferior. From the fwelling of thefe Circular Fibres (which I fuppofe to be in, the Trunk) we may exped: the lengthen- ing of it, for as much, as each of them (be- ing kept from ftarting outwards by the a- forefaid three orders of Fibres and the Skin) muft require much more room than they took up before the>’ were fwollen. This con- tradion of annular Fibres mud likewife make (S3) make fmalleri rafc, upon 'its fhooting out, it was obferv’d always to be.. . J^ow:'vrb€dier-^/^^*iHcreiw^je't^^^ kind nbt, icfcaiindt^ielk'^b^ijig hindered by. the manager to fcarch fof them, lead I fhould make it unfit for prefervation 5 thej^pftrils little way tliat f faw them, At the end of the Pro3()/as diete was, of the fame iubftance with it, a little thing that pointed Qiit likeapeafcV ^hy which the Ele- phant was obferwd to i:ake up very mirmte Bodies. I can fay nothing of the fttu(5fure of this part. , Doubtlefs the- Elephants care to prcferve the iProbofms was great, for when wedisjoint- ed him, we found it thruft near T wo Foot in- to a very hard ground 3 upon which account we thoughtit^ it - had been Burnt, till the Head wasldividtd from ihe; Body, and rfift we found it kept fall to the ground by the Frobofcis. ■. iLThcj Aff era AnerU was large, and deftitute of) an there being no danger of ariy thingsfailinganro the Lungs, froih Eat- ing or Drinking, feeing that there was no E com- Larinx. ( 34 ) communication between the jEfophagus and it. The Cartilagines Arit^noic/es made 2l glou tis , in length about Three Inches and a Quarter, and in breadth about One and a Half towards the middle 5 this Aperture was fomewhat Oval. To the outiidc of thefe Cartilages I found another grow, which was faftend to them, but fo, as to be capable of motion up and down, by the help of fome Mufcles Avhich were implanted in it. It was flrong on both fides of the Ajpera Arteria 5 but op- pofite to the jEfophagus^ or on the under fide, it was very limber. This wanted a- bout T wo Inches and a Half of coming round the aforefaid Cartilages^ on the upper fide, or that next to the JEfophagus. This feem’d to me to fupply in fome meafure the want of an 5 in lefiening iheGlottis to prevent the creeping in of Animals into the Therax. The M?ifcles of the larinx were very firong. I fiippofe, that from the firudture of this part, we may guefs at the rcafon, why the Elephant is afraid of a Moufe, for the Moufe having, room to creep up his Pr der th.e greatefl breaidth oT’the Teeth, ‘ vyas^ Tv VO Inches and Three Quarters 3 and the lead, about an Inch 5 the breadth of the Teeth;pf bocli Jawswasequal 3 the height? of, the Teeth above the Gums, was . about: an Inch and 1 3 thefe Eight Teeth were 'b^phres and fo he had no Incifores, Th ( 41 ) The length of tht Maxilla inferior was 21 Inches and and the brcdth, ^at is, from the outfide of one of the procejfus con fyloJes to the outfide of the other, was 16 Inches and a half, The Vertebrdc of the Collum were 7. thofe oi Vcnehra the l^orfum wcxc 20. To each of the latter there was a pah of Ribs, the Vertebra Lumbo^ rum were only 5. thofe of the Os Sacrum (which are more properly divifions than Fertebra) were fix, a good part of the Tail was burnt, and I could not therefore find oi|t the num- ber of Joy nts in it. The Procefus tranfverfales ac fpincie, cfor- pro:cjtr. fi & colli were diftin( 5 t Bones from their Ferte- yi.fS brae, and joyn d to them by futures. The Vina and Radius did crofs one ano- vim. ther fo, as that the former came from the back part of the Os humeri its proper and u- fual place, and was faften d by its other end, to the fore part of the Carpus, and the latter went contrarywife 5 this pofture of thefe Bones is unufual, and feems to add firength to that part. The Back was arch’d like that of a Hog, which Figure contributes the moft of any to the ftrength of it. Ifhall'giveyouno further trouble, onely F defire ( 42 ) _ defire you would fatisfid thei 'R.

What I now prelent you with is but a Mite, which in hopes of your favourable acceptance, -I freely throw into yOiir inexhaufiible Trealiiry of natural Philofophy. " Fis only Iome Imall Obfervations that I made in the drifeilion of the Eyes of Ani- mals, which I have not found (o much as glanced on ill any Anatonuical Writer. I doubt not but that your deep refeioning-may loon ^kfiprOve them, io as thereby to iolve many of the ‘ Thcenomems of G i Yifion, ( +8 ) Vifion, more clearly and agreeably to truth, than has been hitherto done. But before I acquaint you with thele Obl^rva- tions, I fLippofe that it will not be amils to let you underlland how 1 came to make them , and that was thus : About the beginning of May laft, the ingenious, and delervedly eminent Dr. Willoughby^ deilred me to diffedl an Eye for fome underftand- ing Gentlemen of his acquaintance, who were de- firous to be informed in the ftrudture of it, thatfo they might be the better able to judge of the man- ner of Vifion, and of the Solutions generally given of its feveral Timmnena, I readily complied with him, and having appointed a convenient time and place, 1 met him and his Friends, having brought iorae Eyes along with me j to work then I went, having paifed a Needle and Thread through the Optick Nerve; by this / had it held forme, whilil / was feparating the feveral Coats, giving them Cby the by) to know that the Tunica innominata was only an expanllon of the Tendons of the Mufcles of the Eye, and that the Conpinctiya and adnata were but one Coat , and that the Sclerotica and Cornea were another , and that the Choroeides and Uvea were a third' ; hereby clearing to them what had often puzled my felf heretofore in reading Anato- mies on this Subject. 1 was more curious than or- ( 49 ) dinary in obferving the feveral parts of the Eye,., and careful iikewife in making them underflcod by them, having taken upon me the part of an Jnftruder. When I had quartered the Eye (which is a way I often ufe in Anatomizing of it) at the Optick Nerve, and divided itio almoflas far as the Cornea^ I perceived many Ligaments (for I remember to have reckoned Fifty eight of them in the Eye of an Ox) of a tendinous Nature, proceeding from a part of the Sclerotica^ which was about halt way -be- tween the Nerve Optick and the TrcceJJus Ciliaris^ thence paffing to that part of the Cornea to which the faid 'Trocejfus is faftened : Here tliey were ter- minated, being in length about half an inch^ they were to be leen clear round the Eye, being for the moil part in little furrows made for them in the Sckrouca, They were of difeent llzes, fome - of them equalling in thicknels a Thread but in- differently fine, others being fmaller. They dicE not pafs through any part of the Uvea ot Chorceide^ . neither were they joined to the Ligamenta Ciliaria : ■ Some of them were divided near their Extremities^ and were inlerted info the aforelaid part obliquer ly, ( few of them Jailing perpendictdarly .on it) after they had gone fome way in a ftreight line j fo making .a Triangle with the circular Verge of ^dc\tConm. Thefe new Ligaments are coniine- rabiy more tenle and thick in a very frefli Eye than in a flale one : Since I firil obierved them I had not an opportunity to diirecl; a human Eye , and therefore cannot as yet deicribe them in it 5 but in all the Eyes of Quadrupeds that I iince o- pened, ! perceived them , though neither fo nu- merous , nor lb thick as they were in the Ox Eye, bearing apropjorcion in boLli to the Eye it felf. I found thefe new Ligaments in the Eyes of Fowl, but after a very different manner from thole of Qiiadrupeds, and not Ids remarkable j for in their Eyes they were (though not above 7 or 8 in number j very near as thick as they were in the Ox Eyes, notwichilanding the great dilproporti- on there ii in their bulk. Theie Ligaments pro- ceeded only from one part of the Sdaotlca^ con- trary to that of Qiiadrupeds, and reached to the Verge of the lingly, but more or Ids ob- liquely. The firil chat arrived here was firmly joined to the afordakl Verge for a coniiderablc way, making almoff: a Semicircle; Two more on the lame fide joined with this, and fo tlie Three became one. Three, other Ligaments on the op- polite fide did likewile : Thus I law them in the Ryes oi Geefe, Ducks, Pigeons, cjtc. ( ) Thefe ( as far as I obferved ) are altogether wanting in the Eyes of Fifli, for reaibns hereafter to be alledged. By cutting out the Tunica cornea quite, and gen- tly fep'arating the Sclerotica from the Uvea at the Troceljus ci/wrh, / have plainly feen their Termina- tions, and followed them up to their beginnings, without perforating the Choroeides. By this method of fearching for the aforefaid Ligaments, (which J take to be altogether as good, if not better, than the other) I obferved another thing, of which I fhall anon give you an account. 1 fuppofe (but with fubmiffion to your better Judgment) that the ufes of thefe new Ligaments, are to draw by their fwelling theTunica Cornea^ and with that the Chriftalline humour, nearer the Op- tick Nerve, when the Cone, made of the vifual rays in the Vitreous humour, by the Chriftalline becomes fliorter than ordinal yon the account of an extraordinary Refradtion : Thus to prevent a confus'd Reprefentacion of the Objecff , which would necelTarily happen, if the point of the ic- terledlion of the vifive rays fell fliort of the Men:- brane of Senfacion, whether the ^tma or Chorceide^ 1 Eippofe moreover that for the drawing the Chri- ftalline nearer the ‘Bajls of the Eye, it is neceffaiy the Diameter of the Sclerotica fhoiild be made greater, ( 52 ) greater, To to give way on every fide to the Vi- treous humour, in order to the approach of the Chriftalline to the Optick Nerve j and that this may very well be done by the aforefaid Ligaments, they being fo commodioufiy placed round the Eye for that purpofe, and the Sockets of the Eyes be- ing large enough ftill to comprehend them, and give them Liberty to roul : And further, that from this new acquired Figure of the Sclerotica proceeds the dilatation of the ^Pufdla. The Choroelde ( of which the Irisls a prolongation, that makes the'P/^^ p//L greater or fmaller, as it is more or lefs retra(5i;- ed) being forced to recede with the former, be- comes wider in the middle , and confequently fliorter. But I do not think that the Ligament a Ciliaria ( if any fuch things there be) do any way contribute to this action, forafimuch as they are not conveni- ently placed for this purpofe, they being lo many Qsadii from the circular Uvea to the Center , the Chrifialline, which adling by their intumcLence, muft rather prolong the Tube of the Eye, and lo Icffenthe Tupilla^ than any way fliortcn it, bccaufe that by their fwelling they draw the Circumfe- rence nearer the Center, and that fo the humours being ftraitened for room , mull be forced for- ward and backward j by which means the Eye inufi: ( 53 ) muH: gain in length what it loft in its Diameter. I will anon fubjoin my realon for queftioning the exiftence of the Ligament cl Ciliaria, and endeavour to explain the cauie of Anatomifts Errours con- cerning them,. I do furthermore fuppole, that the Tunica Cornea is made more convex by having its Circumference equally drawn back by the fwelling of the aforefaid new Ligaments; for the Aqueous humour is by that means forc’d forward , and with it the Cor^ nea^ whence a greater than ordinary Refraction is made here. That dcfaclo the becomes more convex in Fowl, by the means of the aforementi- oned Ligaments, appears from their peculiar fci~ tuation before defcribed. My reafon for the want of theft new Liga- ments in Fifli is this : Their Chriftalline Humour is very near, if not altogether. Globular ; upon which account the RefraSion made by it mi:ft be fo great that the rays muft unite very foon ^ and hence it is that their Eyes are ft> depreffed at the back parts) and therefore, for a diftinCt perception of the ObjeCl, it muft neceffarily be fo fixed, that the vertical point of the Cone, made of the rays, fhall always touch the Membrane of Vifion ; which it could not do if the Chriftalline Humour were moved forward and backward , as it is in H Land" ( 54 ) Land-Animals j for ib the rays would make either T\Vo Cones, or a fe6lion of one, and confequent- ly reprelent the Objed: confufedly. The Chriftalline Humour of Fowl is more con- vex than that of Men, or Quadrupeds, and there- fore ought not to change its place io much ; up- on which account I think it is that they have not a proportionable number of the new Ligaments. From what I oblerved of thele Ligaments, an account may be given of the draining of the Eyes : For when we look at minute Objed:s with a fmall light , our Tiipillas may be oblerved to grow wider, (a manifefl: lign of the contra(!Fion of the afore! aid Ligaments) for the reception of a great many rays, todiftinguifli the Objebf.s to be paint- ed on the inner Coats of our Eyes. By the conti- nuance of this podiireof our Eyes for lome time, the; aforefaid Ligaments become weary, and fo dellitute of Spirits to keep them fwoln , that they grow flaccid: and lb from the ftrainins of thele Ligaments We are faid to drain our Eyes. Now-, Sir, I flialldehre to be relolved by you, wliether or no the feveral morions of the Humors, together with the divers Figures acquired by means oif the occadonaliy fwoln Ligamenta nova m the Eye, are fufficicnt to reprelent Objects to us at all di- ilahces, at which they are ufualiy 'perceived by us , with- ( 55 ) without a neceffity in our Theory of Vifion, of ilip- poling an occafional change of the convexity of the Chriilalline Humour, which in fome Animals is lo compa6l, that it cannot be eahly thought fub- je6t to fuch alterations by any aiTignable caufe of them: The only canle that I can imagine of tbele changes in the figure of the Chriftalline, arothe Llgamenta Gliaria^ whofe exigence I above quefUr oned. Now, Sir, fftippofing the being, of thele Ligaments) it is plain from their manner of .act- ing, that they can never contribute any thing to the production of a greater than ordinary refracti- on of the Rays in the Chriftalline, forafmuch as by their contraction, by which they aCt, t\\Q Sclerotica and the Chriftalline being drawn nearer to one another, the Convexity of the latter, by its being drawn out on all ftdes would be chan .Jed, for a mucn plainer /uperpcieSj if its lolidity would give way to it : And thus pronably the rays would re- quire a greater diftance for their incerieCtion than that' between the Chriftalline and - the Qptick Nerve, whence avOLild be a^confus’d Viftpn. In my fearch for thele Ligaments I oblerved that the ’Tunica Choroeides was faftened in many places to the Sclerotifia by thin blackifti '’Make?, of which this lunic ieemod' to conf A. When L conlidered that there were no Veftels in that Coat that con- H 1 tain'd ( 5 ^ ) tain’d florid blood, like thofe in the %etma 5 and that there were always Blood -veflels in the out- flde of the Sclerotica to be Teen, anfwering thole flakes in the inflde of it, I began to think that the Choroeide was an expanflon of fanguilerous Veflels thatreachM as far as the extremity of the Iris^ and Tent branches by the way to the Chriflalline Hu- mour , which made the Trocejjlis Cillaris ; and that the black pigment of that Coat was only blood fo altered in the Figure of its particles by a peculiar Texture of the Sclerotica^ and coiiformation of the Blood- Veflels 5 and that it was contained in thofe Veflels, till they were lacerated by us in difle£Hng the Eye. After a more ferious conflderation, and flridl examination of this Coat I became very well fatis- fied in all thole particulars ,* for by turning the in- fide of the Sclerotica out, and feparati-ng the Choro= tide from it, till I met the aforefaid black flakes, and gently wiping away the pigment with a lim^ ber Cloath, to prevent the tearing of them, I found that thele flakes were Veflels containing an inky Blood, and that they were continued to the Blood- Veffels found without the Sclerotica ; and moreover I did clearly find their numerous Ramifications to have made np the outfide at leafl: of this Coat, meaning the Choroeide^ I faw theegrefs of thele Veflels, from' the Sclerotica netiv the Cornea in many places^, ( 57 ) places, but mod ol all near the Optick^Nerve ; for here both the Coats were intimately joined by innumerable Velfels, whole Branchings in theC/;o= roeide were very confpicuoiis , and lay lo dole to one another, that no vacant Interdice could be perceived between them ; they grew fnaller and fmaller till rhey came near the TvGcejfus CHiaris : But then I obferved that 3 or 4 , and lomtimes more of them, did join in one, which went to the Chridalline, and helped to make the TyeccfjHs Cillaris^ which of fuch Veffels was made clear round. Thele Veflels ^Yere larger than any that I obierved, eidier in the Chorceide or Ihea. Theie Vedels making up the ^ race ffus afoielaid, began to be much fubdivided when they arrived at the Ju^ mca araim^ (which, by the by, I have ve;y often feen before k was expoled to the hir one Minute, notwithdanding what the ingenious Dr. lays to the contrary) and to fend Branches not only in- to the Tunica aranea^ to which they are firmly join- ed, but alfo into the vitreous Humour, which gradually becoming diaphanous, dilappeared, and occafioned (if I midake not) the different Opini- ons of Anatomids concerning the Tunica I-dyalociTs^ I am apt to think that the tenacity of the vitreous Humour is due in a great meafure to thefe Veffels, numeroufly branched through it, for ufes hereaf- ( 58 ) ter to be affigned, and that from hence it is that the inner as well as outward part of it is tough, and that the nearer theChryftallineyoii would lacerate it, the more difficulty you will find in doing fo , becaufe that the Veffels are fhrongeflin that place. To thefe the' flicking of this Humour to the Chri- ftalline is iindoubted’y due , as that of the Chri- flalline to the Uvea or Choroeides, In wiping away the pigment from the Trocejfus cularis^ I perceived round, whitifh Bodies, which at firfl I cook to be the Llgnmenta dliaria, but upon a narrower exami- nation of them 1 found that they were hollow, ha- ving upon pricking, difcharged the lame blackifii Liquor with the refl of the VefTels, before they had it all forced out : But after all this Liquor was thrufl out, they looked fo like Ligaments that I flioLild have erred (as wtell as mod other Anato- ni ids have) in my opinion of them, had Lno.t be- fore thought the proccjjus aliarts to bea continiration of the Blood'- VelTels, which I round made up trie Choroeidcs and Uvea ; and for that F^ealoiiinforiTied my fed in the truth of it, as well as 1 could, _ by frequent dilTedlions of the Eyes of the lame, and ofdiffierenc Animals. By this / did very well .la- tisfiemy Iclf, that what Anacomids took to be gamenta cillaria^ was really Blood -Veflels; out of which all their Blood waa forced. This /found pretty •pretty well made out by the following Metfiod, I leparated the Sclerotica altogether from the Choroeide^ and with it the Cornea^ and then /threw it into a Baibn of Water, where / moved it to and fro, thereby to wafli the black Liquor out of as many Veilels as were torn in the leparation of the Two Coats. This loon difcovered to me the DL viiions, and Subdivifions of the aforefaid VeBels, and their Coalitions to make the ^rocejfm cilkris ^ and their further diviilons into the vitreous Humor and Chriftalline. In the Eyes of Fowl I obierved the Twnca Cho= roeides more plainly to con(i(l of the above menti- oned Vefiels, than that of Quadrupeds , before 1 waOied it in Water : But in the Eyes of FilE it was mod: plain of all, for in the Eye of a Whiting the back part of the Choroeides was nothing but Yef- fels bird with florid blood , after a fofcEibflance of divers colours, which defended it from Water, that I generally obierved to lodge between that and the Scleyotica^ both in this and in other Fiili, was ta- ken away. This Coat was not lin d on the infide with any thing that 1 could obierve in thele Ani- mals, but in QLiadrupeds I always found a fub- ftance intheinlide of the Qhoroetde^ which was ten- der enough to proceed from the 'P/u Mater ^ and which according to lome is the Organ of ienfation. The {6o) Tfie tendemefs of it 1 found when I turned the in- fide of both the Choroeide and Sclerotica out, by gen- tly fcraping of it away ; for thus without any dif- ficulty I have taken away that lining, /have not at prefent opportunity enough fully to fatisfie my feir, whether there is any fuch lining in the Eyes of FiOi or not,- but fiiall, /hope, e're it be long, be able to give you an account of it. Jdo the more infill: on this now, becaule that if there be no fuch thing, / fhall ealily prove that the Choroeide is not the organ of lenlation, but the ^tina^ not- withfianding the Experiment with the three Pa- pers. / do not doubt but there is a circulation of the Humours in the Chorotide as well as in all the other parts of the Body ; for the Veins on the outfide of the Sclerotica contain a fubfiance very like that pig- ment, if not the lame, which queftionlels is lent thither in order to its mixture with the mals of Blood. / do not lee any reafon why the Repara- tion of the Humours of the Eyes is not as requifite, as that of the other parts of the Body, which we find continually done by the circulation of the Blood, forafixiuch as in a litteral fenfe we die day- iy. Doubtlels it is from Natures care in repairing them as they are wafted, that the aqueousHumourin Fowl BBBSa {6l) Fowl is (b luddenly reproduced after it has been ipik ; ^Tis probable for the lame Reafon-, tiiat it would be fb in ocher Animals too ^ for it is eafie to conceive how a femn will gleet out at thefc Capillary Vefleis. when they are not (o fhut up by any Cutkula or Membrane j but that there is fbme palTages left neceffarily open for the iiipply of what is wafted of the watry Humour, to pre- vent the Cormds growing flaccid , as we find it does in a little time after the Animal is dead ; which I fuppole is occafioned by the ftagnation of the Blood, becaule that it is not recruited as it is Ipent , as it was wont to be by the circulation of the humours in the living Eye. We may from this notion give a probable account of Cataratfts, which ! take to be this : The Vefleis in the Iris may at fome times be more open than is requifice, for the ferum of the Blood to get in to the aqueous humour, to repair - what is fpent in perfpiration, and fo may give way toavilcid matter, diluted by the ferum, to the fame humour, where it muft lie ftagnant, for- afrnuch as it cannot pals through the Pores of the Cornea along with the ferum, becaule of the fmall- neft and incongruity of the Pores to the vifeid Particles • and fo in time it acquires a conllftency, like that in old diPrilled Waters, which is called I the (^ 2 ) t Ae Mother : And thus lofing its tranfparency by degrees, it gradually intercepts the vifiveRiayes before their arrival at the Chriftalline,- whence firff an obfcure, and at length no Vifion at all. This flimy matter, called the Cataract, in a long time becomes ripe ; that is, arrives at fo great a degree of vifcidity , that, without breaking, it will endure winding about a Needle, in order to its being couched, or laid behind the Iru^ between that and the Chriftalline Humour. The contrivance of the Choroeide is very admira- ble, not only for repairing what is continually wafted i n the Three Humours , but alio for fix- ing the Chriftalline Humour in the moft conve- nient place for refracting the Rayes, and fo as to be capable of being moved backward or forward upon occafion *. And moreover for altering the Texture of the Blood, fo as to darken it felf for the moft commodious Picturing of the Objects by the Chriftalline, in order to fenfation. This I iup- pofe it does by carrying back in its Veffelsall the feculencies which may get into the Humours, and might make them unfit for refracting or tranfmit- ting the Rays , and by fending a Blood, either precipitated, or fo changed by a peculiar Confor- mation of irsVefsels, toprelerve, with a tranR parent fuccuSj the humours in their due proportion, making the Capillary Subdivifions no way adapt- ed to the black and grofser Particles. I have Icen in the Eyes of Fowl what the curi- ous Monfmir Terault firft oblerved in them, name- ly the little black bag, reaching from the Chriflal- iine Humour, to which it is faftened through the vitreous to the Nerve Optick, into which it is re- ceived (if my memory does not fail me,) and is withoutfide continued to the Blood-Vefsels, which he fuppofes to be a Cloaca^ defigned to defecate the Humours w^hich in thefe Animals ought to be extraordinary clear, for the diftindt perception of Objed:s at a great diftance. I have feen the like (if I forget not) in the Eyes of Fifli. I take this to defecate the Humours after the fame manner that the Velsels of the Choroeide do, and like them to bring nourifhment too , being rather a Fafciculus of Velsels, than properly a common fhore. I forgot to let you know another Method that I ufed to find the Ramifications of the Velsels, which I defcribed in the ChoroeideSj Kyea^ Frocejfus cilice rlsj and vitreous Humour, which was nothing in- feriour to the others above mentioned ; I lliall therefore acquaint you with it now, being as fol- lows. I kept the Eyes of an Ox for Two or Three days, in hopes that the black Liquor contained in I 1 the (H) the Vefsels, might ferment to that degree, that it would be able to burft the tender Velsels ; an4 that lb they would be cleared of a great part of it, by which means their Divihons and Coalitif ons mjaht be the better difcovered. This luc- ceeded according to my Expectation j for having taken off the Sclerotica and Cornea^ and thrown the Eye into Water, and there ffirred it for fome time, 1 faw all that I above defcribed very plainly., Since I firft made the aforegoing Obfervations in the difseCtion of the Eye, my occafions were fiich,, that I could not fpare time to make a comparative- Anatomy of the Eyes of mofl Animals to be had in our Countries, which I take to be the beffc way of informing our felves in their ftruCture, and in find- ing out the iifes of their feveral parts : But e*re long ! hope! fhall have leifure to purfue that defign, & be able to give you a further account of this mat- ter, which I fhall not negleCt to do, being refolved' to omi- no opportunity of manifefting my fenfe of your Obligations, and to fatisfie you that I am,.
