Part IV. 0f the Seminal Weft/er, 21L Cluflers, running in divers annders, to give a {top to the over~hal7ty Ex- cretion of Semen 5 lo that finall Cavities atmulating the Cells of Poniegm. mte Seeds in Figure, are f0 many Repofitories of choice Liquor, wherein Nature hath wifely conflituted f0 many referVes of it, to {Peak her felf a good Honfc-VVife, in the provident conduct of her Stock, by not turning Bankrupt, by the profufe expenfc of fo excellent :1 Liquor in one aft of Coirion. Great Galen, I earned Doctor Highmorc, and many other Anatomilis, do dedicate thefe rare chieles, the feleét Cifterns of refined Liquor, to thc meaner office of rendting the Urinary paflage hnooth and flippery, by its kind of Gelly hued with Alli-colour; and 1 Probe being immitted into an. open Velicle, it was carried obliquely toward the "ref/1m, and did termi~ natc into a Hole, common to the Deferent Velfel, and Seminal Veficle. The other part of the Velicles, was accommodated with a Glandulou: Texture, which hadgreater Dimenfions, and were thicker and broader when they were in conjunction with the urethra; in the place where the Deferent Vell‘els do terminate, the Glandulous fubltance is much more nar- row and contraéted. This Glandulous Compage appertaining to the Velicles, did much refem- hle that of the Tellicles in likcnefs, only it was not altogether of fo bright Unétuous nature, to fecure it againfl: the acrimony of Urine, as impraegna. red with Lixivial, Saline Particles. But I conceive it more probable, with the pardon of thofe Renowned Authors, to aflign the lining of the lint/2m to forne vifcid lVlatter, which defendeth the Stomach, Inteftiiies, Bladder, a line, but inclining fomewhat to Alli-colour. as well as Urethra, againl‘t the troublefome attempts of {harp Corroding Tubes, will eaiily pafs into the common Dué‘t, which doth not immediate- N arr. I‘nd to that intent, the furface of thefe greater and lefs Recepta- cle;, are anointed with clammy Matter, ariling out of the Recrementsof the Blood, perpetually defiilling out of the Extreamities of the Capillary Arteries, by reafon tliefe Seminal Veficles are the allodgments of excellent Liq which hath no conftant efilux into the Urinary paffage, performed ly dilcharge it fclf into the urethra, by reafon it was covered with a thin . the aft of Coition, or when Nature is overcharged with too great a liilncfs of the Semen in Nocturnal Pollutions, or in more extraordinary cafes of Cotiorrhma's. The great Current of Anatomifts, aflign the ufc of the Seminal Vclicles, to be only the Repofitories of Seminal Liquor, till the act of Coition; and to that end, molt are of an Opinion, that the Deferent Veifels, do tranfmit t‘ e Semen, receiving its firft rudiment in the Teflicles, and afterward is l‘:‘Ol'C' matured in the Paraftats, into the Seminal Veficles, therein to be referred in order to a farther ufe. And in truth, it may be eafily granted, that thefe Veflels are the Repo‘lEOI'lCS of Semen : But a (Liel'tion may arife, Whether they receive it from the Defer-em Veffels ? With which, as Doctor Wharton will have it,rhey hold no entercourfe by any common Duc‘t: And farther-more it is his Sentiment, thata Semen is Elaborated in thefe Veficles, dil'tinét from that of the Tefticles and l'ai'al'tats 5 by reafon thefe Vcficles being furniflied uith a Glandulous fubfianee, do produce a peculiar Spermaticlt Matter. Elfe if their This Glandulous fubftance, hath its infide befet with many Minute Ca.- vities, which all concenter in one common Duct, before they arrive the Urinary pallage; and a Brifle being immitted into any of thefe Glandulous Membrane, pinked with Minute Holes, through which the Semen doth guih in the act of Coition. And it feemeth very probable, that the Geni- tal Liquor,'concoé‘ted in the body of the Glands, i3 tranfmitted through many Minute Vcfl‘cls into the Cells, as fo many Receptacles of Elaborated Semen, (of another nature from that of the Tel'ticles and Paraflats) which is of a more White, and greater Confidence, but this of the Velicles is more thin, and endued with an Alli-coloured hue. learned Dc Grmf, doth oppofe this Opinion to his utmol'i, Libr. ole Virrori'm Orgnmr (fpealiing of the Seminal Veficles) Ear mm Semim' recipicmlo fcjgoncmm/o {ltfftlldms oflc, quad a weriratc aliezmm extflimamm, prime quad i/a (fifl'flflfd' fmt, m [amen per ‘I/{Ifd deferemia aflncm‘, (7 Mom in uretbmm fltuments in the generaliori of Seed. Ex that: PrIICt air We probabi/c non eflE Naturzzm tam Pam/o apparam tantd.' 792' againlt Doflor Wharton: Opinion, by Famous fie Graaf, who affirms, That and to take the freedom to make this Reply, to the Reafons alledged the Seminal Veficles are fo ordered by Nature, that the Semen flowing through the Dcfcrent Veli'els, finding the paffage [hut up by a Caruncle, ought to return into their Cavity, and be Conferved there, till a fit time nature, are defigned to form: more noble Office, to the produélion of form: and place of Excretion. Seminal Liquor. Which fcemeth to favour the Opinion of Learned Dofim‘ Wharton, becaufe a Semen may be feen in thefe Veiicles of a different nature, from that of the Tefticles and l'araftats; as it appeareth more plainly in the Seminal chicles of greater Animals. " Of this, an Inl'tance may be given of an Horfe, the flruélurc of whofc Velicles, is integrated of two parts a the one Membranous, the other Glan- the Semen pailing into the Deferent Veffels, is not tranfmitted into the Sc. minal Vefrcles, but lodged in the But-end of the Deferent Veffels near the "ref/1m, into which a Perforation being made, the Semen is impelled in time of Coition. ' And this Ingenious Authors fecond Argument, is 'this, That the Seminal Vt'ficles have but a thin Membranous fubf'tance, endued with no Glands, dUlOllsa and the Veiicles being Diffeé'ced, were of far greater Diinenfions, greater proportion of Seminal Liquor, which in a Horfe doth refembllc 3,1 having no vilible Ducts, or any other Inl‘truments, fitted for the generation of Semen. V'Vhence he inferreth upon the former Difcourfe, that Nature doth not attempt the production of f0 great a Matter, with fo fmall an Apparatm, 'lm. as then thofe of a Humane Body, and if filled, Would entertain a very mUCl‘ De Graaf dcnicth the Scbcminil chi- ties to be in- G CIICrlei(}71Ul}I I-Imliri, "if! diromm tam V[Ifculorum Semindriorum, Epididymidum, (1mm drfl'reulimn longiflimoo 'DItflm fruflra creator Ml}, qui uti flperim diximm mil/um nliiim from rcflliriimt, 11mm fcmiflir Generatzonem.
