The lituation of the Orifice of the Value and Vagina in other Animals, is different from thofe of Birds, in the firfl they are lodged between the Vejinz and Intcfliimm realm", and in the other, there being no Vefim, they are feared next to the Rump and Spine between it and the Izzleflinum Regain. Having difcourfed the outward Orifice and confines of the "term, I will now apply my felf to its more inward Recefles, to the Repolitory in which the Egg is brought to perfection, as encircled with its white and (hell; the paifagc to the "term is called the Vagina in other Animals, in which the Pe< mix is immitted in the time of Coition. In Birds this entry toward the Cavity of the Matrix is very loofe and full of folds, which are rendred more fmooth and plain, when it is difiended upon the exclufion of an Egg; but on the other fide the rPenis or Seminal Liquor cannot pafs into the body of the "term, as it is difficult to immit 3. Probe into it. And Fabritim‘ is of an opinion, That Aer cannot be injeéied into it; whereupon it is not eafie to conceive that the Cock can throw in the gtoflhr but only the fpirituons particles of Genital Matter into the Cavity of the Matrix, by rcafon there cannot be difcovered any manifeft difference between an impregnatedé ‘ an The "term is compofed of many Coats, the firft is Membranous, as The third and inward Coat is narrow, as integrated of a company of The third Nervous Fibrils, (making their progrefs up and down in feveral politions ) Coir. which being conjoyned, do confiitute this fine texture cndued with acute fenfation‘, whereupon the Egg after it hath acquired a due maturity, groweth ttoublefome to this tender Coat, and thereby draweth the neighbouring Helby Fibres into confent, and fo difchargeth the importunare gueft. Between the middle and inward Coat are lodged a company of fin-all Glands, which are f0 many Colatories of the Blood, and, prepare a Mar/era [Mb/irate for the produétion of the white and {hell of the Egg. Th Clinlztf the 'Unrrra. The "term of Birds is furnilhed with numerous divaricatious of VeiiEls, The \‘tITels of (it; "Ulrnu‘. Arteries, Veins, and Nerves. The Arteries are derived from the defcendent Trunks of the Aorta, and have more numerous Ramulets than thofe of the Veins, and grow much greater in impregnated Birds, and the Arteries do exceed the Veins in number, by Th: Arttrics Cxxt‘d [er _ Vtinsiii numa bet. reafon, as] humbly conceive, they import a Seminal and nouriihingr Liquor, which is ablilmcd, in the formation and nutrition of the white, yolk, and [hellof the Egg. The Veins of the "term" are fewer in number than the Arteries, and do take their rife from the Trunk of the Vena Cave, and reconvey the Blood from the 'Uterur toward the Heart. The Miami alfo is accommodated with Nerves derived from the Spine, which do aifociate the Arteries, and contribute a choice Liquor, which may claim a {hare both in the Generation and nourifhment of fome parts. The life of the Glands is very great, becaufe as the Colatories of the The of: chine Glandsbc to [he Blood, they are fine minute aggregated Bodies containing variot‘rs kinds of longhig ‘Utsriu. Veffels; The Arteries import Blood mixed with Chyme into the body of the Glands, where the foft albuminous and ferous parts are fevered from the Purple Juice, and confederated with a Liquor deflilling out of the Nerves, and carried by fecret paliages into the cavity of the llterm, where it makes an accretion to the yolk of the Egg, and formeth the white and fire", and alfo, asI apprehend, this fine liquor of the Blood and Nerves, Cccccccc cloth. |
