This ufefiil part of Birds is made up of a various fubltance, partly Membranous and partly Glandulous; the i‘uriface of it is Membranous, compo- ‘ {ed of right, tr'aniverfe, and oblique Nervous Filaments, curioullv interWoven,and to clolely adapted to each other, that it isimpoliible to difcern the interiims oi‘the moi‘t minute nervous threads runningin variety of pofitions up and down, directly, obliquely,and croiTways,in order to frame this fine Contexture. The more inward part of the Ovary is compofed of a (oft, porous, {pongy lirbl'tauce, made up of numerous Glands, befet with the terminations of Arteries, Veins, Nerves, and numerous Perforations, through which the Seminal Liquor deltillcth into the cavity of the Ovary, giving the firl'c rudiment to the Eggs. Thisrare Compage, integrated of a Membranous and Glandulous firb- theholes of the Glands into the cavity of the Ovary ) are conilioled of a affixed to the Ovary, and afterward are parted from it, when they arrive a due magnitude. There Coats immuring the choice liquor of the rough delineated Eggs, are enameled with branches of Spermatick Arteries and Veins, firft imparted to the ovary, and from thence communicated to the common Coat of the Eggs, (as proceeding from the Coat of the Ovary) to give them heat and life. In the Ovary are lodged a great company of Eggs, adorned with an Orbicular figure and different magnitudes, the greateft are placed about the Circumference, and the fmaller about the Center, which is very confpicuous in the Ovary of an Efiridge as well as in thofe of other Birds : The firii ori- The [gas of an Ellrrrlg.
