The Deferent Veflcls are a continuation, as I conceive, of the common a Stniinal Channel, beginning about the midle of the l'arafiats, being akin to Nerves, in hardnels of their iiibftance, but not in {truaureg by reafon Nerves are Syflemes of many Filaments, clolely united to each other, by the interpofition of fine Membranes 5 but the Deferent Tubes, are round, white VellL-ls, endued with manifei't Cavitie=, to give a reception and conveyance to the Seminal Liquor, elaborated in, and tranfinitted by the common Duc'is of the Paraf‘tats, into ‘tllC deferent Cylinders; which when they wheel in Males from the bottom of the Tefticles, they are carried upward Obliquely for a little fpace, and then aiceiid iria fltaight courfe in company with the Spermatick Vellels, through the Proc‘bh of the, @ci~ilonxtrllz, into the Cavity of the loweflt Apartiment, from whence they are reflected, tending to the hinder region of the Bladder, between which and thc Inteflinum @kcéium, they are inferred into the Neck of the Bladder, and Expanded as it were into many Cells, and afterward being lcfleiied again, do with a clofe paflage, terminate into the Seminal Veficles.

If you have not Faith enough to give Credit to this Defeription , you may be pleafed to immit lbme Liquor by a Syring into the Defer-ant Vefl'els, whereupon you may plainly difcerii the Seminal Veflcles to be lodged on each {idc of the Deferent Veflels, between the Bladder and the Imeflinum Ream): , and are framed of many finall Cells, interfperfed with a Glandu- lous fiibfiance, relhinbling a.

He Seminal Veficles are very large, and of a Tranfparent nature in The Seminal Vcficles. Bates, and f0 clofely united, that they feem but one Vcficle, but upon a fltié‘t enquiry, they may be difcerned to be a pair of large Velicles, confifiing of many difliné'c Cavities; and each of them hath a peculiar In. fettion into the 'Uretbra, and each Infertion endeth into many final! Holes, through which, upon the compreflion of the Veficles,‘ a quantity of Seminal Liquor doth flow into the common Urinary paflage: And in a little Guine Bore, the Seminal Velicles are adorned With two Horns, and are Pyramidal, and have many Spires, or Wreaths, refembling Worms, extending tliemlelves as fat as the Kidneys. The Rrutturc The Feminal Velicles have a rare Strufiure, compol‘cd of great variety of of the Semi. Vellels Arteries, Veins, Nerves, and many Branches of Lymphaeduéls, ena- nal Vchclcs. lllCllllq'fl thin Membrane, enclofing divers fmall Apartiments, accompanied with inany Glands, made up alfo of diflerent Minute Tubes. As to the Figure of theft: Seminal Veficles, Ingenious De Graaf doth liken them to the Intel'rines of Birds, which have many Circumvolutions, and differ from them, in reference the Vcficles have many varices, which are dilated after a firangc manner, according to their outward Surface, and are found to be much narrowed in their inward Allodgments. The length 0! Thelbl‘xeoolitories of Seminal Liquor, commonly obtain the length of the seminal three Inches, or thereabouts, and have not the fame requality in each fide, Veficlcs. by region one execedeth the other in greatnefs, and have the breadth of a Finger, and is not azqually proportioned on both (ides, in which the thicknefs is greater and leis 2 So that one fide of theVeficles, is dif'proportionedto the other in all Dimenfions of Longitude, Latitude, and thicknei‘n And if you take a hirvey of the more inward RecefTes, they Will appear in fome parts more Dilated, and in others more Contracted. So that Nature pleafeth her felF, as. to thefc Receptacles of Semen, in great variety of difl‘erent Dimen- (ions, which is rare in other parts of the Body, where they are rendred pairS by Nature, as having great affinity in Simihtude, arid Proportion, in which for the mol'r part, they refemble each other in (equality. They are made Twins by Natures Wife Contrivance, compofed of many Cells parted from each other, by Mcnibtanous Interftices, as by fine Walls, to The many Cells in (he Seminal Vt: fitlct. make their various Partitions entire, as fevered from each other; {0 that each Cell mioht dikharge it {elf in relation to the Seminal Liquor,w1thour the entercourl‘e (if another": W hereupon they ate iinmui'ed with their proper Coats, as confining them within their peculiar Territories, and do emit Seminal Juice, by diflinét perforations into the Urinary paflage, that Generation might be the better aeeomplilhed, when one Veficle is difabled, either by Cutting for the Stone, or by Contulion, Abfcels, Ulcer, or any other Dif- cafe; the other performing its Oflice, might render the great work of Pro- a atio liiccefsful. _ P gl‘helpe Minute Cifierns of Seminal Liquor, are not furnifhed only With a large {ingle- Cavity, but with many [mall Receptacles, feared as it were in Uuunuu Clufiers, The Ufc afthc many Cells in the Seminal Vcfltlcs. |
