Part I I 1. 0f t/ae Spleen. 4.1 5 Oval Glands of the Spleen, do cover the excellent Mylteries of Nature, as with a dark Veil : Whereupon divers Difputes have been broached about the Subf'tance of the Spleen, which as yet have not been Determined, Mar- jimmy; my I earned Anatomifis have thought it to be near akin to that of the Li- ff," ver, and be different only in its more lbftand loofe Compage , and it hath EX» been generally approved heretofore, by many great Profeflors of our Facul- 3‘ 9: ty, that the fubltance of .the Spleen, is a Body of Concreted Blood ( as a Foundation to fupport a multitude of tender Vell'els) which according to them, hath much afiinity with the other szczm, the Heart, Liver, and Kidneys. Excellent Malpz‘g/Jim, (to whom the Learned Commonwealth is much in- MIME" h it‘ove debted, for many great difcoveries of Natures fecrets) having made a great Eciini'dml. fearch into the inward Receflbs of the Spleen, hath found the Body of it, billighSplgc‘cst. to be a Syl'teme of many Membranes formed into divers Cells, as f0 many ay be farther inquired into the nature of thefe Fibres, (by reafon Minute Apartiments: And although the Diffeéted Spleen feemeth to be ‘_ they have been taken for Blood Velfels) whether they are endued with any framed of Concreted Blood, and may be in fome part brought into a Fluor ,r And it "‘2 manifell Cavities? To which the Reply may be made in the Negative, As i I they havemany thin Filaments, f0 cloliely adapted to each other by fine hiembranes, that no evident hollownefs may be difcerned, and in this capacity, they have a likenels with Nerves, which are compages made of many fine Threads, deltitutc of all vilible Cavity: And great fearch hath been "made, \Vhether thefe Fibres fprouting out of the inward Coat of the Spleen, do end into fome determinate part, in the manner of other Excretory Vef- his 3 but upon a diligent inlpeé'tion into the progrefs of 'the Fibres, (which fecm to be the propagation of Nerves, as having the fame frame) they may be traced from the upper to the lower inward Tunicle, invelting the OHS Spleen, and fome of them into the Can], and others only into the Camila, by Attrition 5 yet in truth, it is a fine aggregate Body, of Membranes, ch. fels, and Glands, which are very much obfcured with the covering of acre~ ted Particles of Blood, adhering to many fine parts, conltituting the fub, fiance of the Spleen; which may be made more evident by the injection of TEES: Air ( the Artery being tied) into the Splenick Branch, whereupon the b0. 33‘,,‘:;;";, dy of the Spleen groweth very much Turnel'ied, and fomewhat Diaphanous, 58m" f0 that the Sinus, and finall Membranous enclofures maybe in lbme fort dill cerned ; as Learned Malpigbim hath affirmed it. And farther, This Learned Author faith, That if the blown up Spleen be ""53""; or dried, and an Incifion be made into it, you may difcover its fubftance for the taillight: mof‘t part to be integrated of Membranous Sinus, and Cells, refembling the $323,211,," or the common Integument of the Vellels, and into the fubltancc of the Glands, relating to the Spleen; whereupon it may be thought reafonable, Holes of Honey Combs in Figure; which are very hard to be difcovered, becaufe while the outlide of the Tumetied Spleen is dried, the more inward that form choice Liquor, impregnated with Animal L'pitits, and propagated from the Nt-rves, may be tranfmitted between the Filaments of thel‘e Fibres, ftcps of the Membranous Cavities remain : And the Air being forcibly in- {into the l'arenchyina of the Glands, where (as I molt humbly conceive) ieéted by a Blow-pipe firll: into the Splenick Branch, and afterward into the it may confederate with the Blood, and cnoble it with its Volatil, Saline Parricles. The Spleen is not only furnilhed with great variety of Arteries, Veins, and Nerves, but Lymphaeduéts too; which Allertion is backed with the Au- more inward Recefles of the Spleen, whereupon the thin Tunicles, as fo many tender "falls of the Cells are broken, and the Spaces become more enlarged : So that the firué'rure of a dried Spleen is fomewhat obfcure, and thority of many [earned Authors, Malpi‘gbim, Dicmcrbroerk, Fran.

This Splenick Sinus, is attended with fruitful Branches of Veflels, divers of them determining into the Membranes, immuring the ambient parts of the Spleen.
