The Glands of the Mefcntciy, are its very proper and fignilicant parts, as they are dtefled with Milky Velfels of feveral kinds. of which fome import the Creamy juice into, and afterwards others receive it, and carry it from the liibliaiice of the Glands, toward the beginning of the Mai/entry; fo that the Milky Velltls and the Glands, have a necellary dependance, as they are fubfervient to each other. The fubftance of thefe Glands are white, tender, and friable, and con- i lilieth of many linall Globules, as f0 many Minute Glands, which are co}vered with peculiar thin Coats, difiinguilhing them one from another, and >receptacles of Chyle ( tranfmitted into their inward Recelfes by Milky Veins) which may be eafily feen, if an lncilioii be made into the Glands, ( fome few Hours after Animals have been fed) which being fquee- fed, a thin Liquor will dillil from them; which is more white in young, and of a darker hue in elder Animals. Thcfe Glands may be Difcriminated from thofe of other parts, in relation to their peculiar firuéiure, as compofed of divers kinds of Milky Veins, and are infiituted by Nature to preferve their tender Ramitications, by a fafe conduét of them in their palfage toward the common Receptacle. Nature fporteth it felf in great variety of {hapcs end fizcs, appertaining to the Mefenterick Glands, and are much lefs in Man, then in Dogs and Cats, and many other Creatures; and are lodged between the Coats of _ _ . the life/emery, oftentimes cncompalfed with Fat, and do feldom exceed the Tlicil' fitiiaiiv - - . . , mi, Mum" bignels of a Kidney Bean; and are feared in feveral parts of the firefmtery, bliZIiielszii-l'ihe bOYh abOUE its Center, as well as Circumference, as moft convenient to enter- Mrftfl'm- tain the Milky Velfels, which pafs through all Regions (above, beloW, and middle) of the Mefcntcry; whereupon it is befct with numerous {mall Glands7 both in the middle, and about the Margins of it.
