Immediately above the Reins on each side, is a flat and soft Glandule, of the thickness of a Nut; they are nam'd _Renal Glandules_, or _Capsulæ Atribiliariæ_, because they contain a blackish Liquor, which (as they say) serves as it were Leaven for the Blood, to set it a fermenting. _What is the Bladder?_ It is the Bason or Reserver of Urines, of a Membranous Substance as the Stomach, being plac'd in the middle of the Hypogastrick Region; so that it is guarded by the _Os Sacrum_ behind, and by the _Os Pubis_ before: Two Parts are to be distinguish'd therein, _viz_. its Bottom and Top; by its Membranous Bottom it is join'd to the Navel, and suspended by the means of the _Urachus_, and the two Umbilical Arteries which degenerate into Ligaments in adult Persons: As by its fleshy Neck, longer and crooked in Men, and shorter and streight in Women it cleaves to the _Intestinum Rectum_ in the former, and to the Neck of the Womb in the latter. Lastly, its Office is to receive the Urines to keep them, and to discharge them from time to time. _What are the Genitals in Men?_ They are the Spermatick Vessels, the Testicles, and the _Penis_. The Spermatick Vessels are a Vein and an Artery on each side; the former proceeding from the _Aorta_, or thick Artery of the Heart; and the other from the Branches of the _Vena Cava_ of the Liver. These Arteries and Veins are terminated in the Body of the {75} Testicles, which are two in Number, enclos'd within the _Scrotum_. The Office of the Testicles is to filtrate the Seed, which is brought thither from all the parts of the Body, thro' the Spermatick Vessels, called _Præparantia_, and afterwards to cause it to pass thro' others nam'd _Deferentia_, to the _Vesiculæ Seminales_, from whence it is forc'd into the _Ureter_, thro' two small and very short Canals. The _Penis_ or Yard is a Nervous and Membranous Part, well furnish'd with Veins and Arteries, containing in the middle the Canal of the _Ureter_: Its Extremity, which consists of a very delicate and spongy sort of Flesh, is call'd _Balanus_, or _Glans_, and the Nut, the Skin that covers it being nam'd the _Præputium_, or the Fore-Skin. Thus by the means of this swell'd Part, and stiff thro' the affluence of the Spirits, the Male injects his Seed into the _Matrix_ of the Female, to propagate his Kind. _What are the Parts appropriated to Generation in Women?_ They are the Spermatick Vessels, the Ovaries or Testicles, and the _Matrix_. The Spermatick Vessels are a Vein and an Artery on each side, as in Men: The Ovaries or Testicles, situated on the side of the bottom of the _Matrix_, are almost of the same bigness with those of Men, but of a round and flat Figure. The _Vesiculæ_, or little Bladders which they contain, are usually term'd _Ova_ or Eggs by Modern Anatomists; and the Vessels that pass from these Testicles or Ovaries to the _Cornua_ of the _Uterus_, are call'd _Deferentia_ or _Ejaculatoria_. {76}
