The Testicles of a Woman are call’d _Ovaria_; and they differ in Situation, Figure and Substance from those of Men. They are seated within the _Abdomen_ upon the sides of the bottom of the Womb. Some Writers are of opinion, that Nature plac’d the Testicles of Women within to heat the Seed and work it up to a degree of perfection: Others tell us, that the design of this Situation was to excite Women to Generation. The use of the Testicles is to filtrate the Seed and reserve it; and to perform at once the office of a Man’s Testicles. Their Figure is broad and flat, (seldom exceeding the Substance of a small Pigeons Egg) they are tied and held fast by some part of the Flag of the Trumpet; and they are knit to the spermatick Vessels, which grow larger after the Egg has taken Root in the Womb. For their Substance, they are a collection of Vesicles, commonly took for Eggs. In the _Ovarium_ of a Woman are a Million of fine small Blood Vessels dispers’d upon the Tunicles; and small imperceivable _Glandules_, that strain out a white milky Liquor, which attains perfection in the cavity of these Vesicles, and then composes the matter of the Egg, which includes the Sperm that contains the _Fœtus_. The more volatile part of the Seed of a Man passes through the _Tubæ_ to the _Ovarium_, in order to fecundate the Eggs. The _Tubæ_ are of the form of a Trumpet, which gives them their Name: They take rise from the bottom of the Womb, and their Orifice, which is continually open, is lac’d round with small Membranes like a Fringe, and is call’d the _Devil’s-bit_, or the Flag of the Trumpet. The office of the _Tubæ_, is to facilitate the descent of the Egg into the Womb. The seminal Spirit puts the _Tubæ_ in motion, whereby the jagged part embraces the _Ovarium_, and the Egg fermented by the Spirits of the Seed, insensibly, disengages it self from the _Ovarium_, and breaking its Membrane, enters the _Tubæ_, in order to descend into the Cavity of the Womb: And in case of Twins, or where two or three Children are Born; they always spring from the like number of Eggs, disengag’d from the _Ovarium_ at the same time. The extremities of the _Tubæ_ inserted into the bottom of the Womb are call’d the _Horns_. The Womb is cover’d with the _Peritonæum_; and a peculiar Membrane which lines the whole inside; and the bottom is generally smooth and even, but the Neck is always furl’d. The Ligaments are nothing else but Productions of the _Peritonæum_, which come from the Loins, and are inserted in the bottom of the Womb to prevent its falling down upon the Neck: They likewise keep the Womb from mounting too high: When these Ligaments are unbent, they resemble Bats Wings. There are several _Lymphatick Vessels_ belonging to the Womb, which creep along its outer part, and after a reuniting into large parts, empty themselves into the Cistern of the Chyle.
