THERE are moreover other small _Vessels_, springing one from another, which tend to this _Orifice_, and serve in _Plethorick Women_ with _CHILD_, to carry off the Superfluity of the _Humours_. And, in short, prudent _Nature_, seems to have so ordered _These_ to prevent _ABORTION_, which might easily happen, if the _pregnant_ WOMB was too much expos’d, or was to open itself for this Purpose. THE _Seminal_ or _Spermatick Vessels_ are _Four_, like as they are computed to be also in MEN, and differ only in being _shorter_. The _Blood Vessels_ are very winding; and the _Spermatick Arteries_ arising with a narrow Origin from the _Aorta_, form various _Plexus’s_, and _Inosculations_, as _These_ do: And the _Spermatick Veins_ (tho’ without _Valves_) have the like _Inosculations_ with the _Arteries_, which however in _These_ are more conspicuous. THE _OVARIA_, or _TESTICLES_, are _Two Bodies_, on each Side _One_, annexed to the Bottom of the WOMB, at about Two Fingers Distance, near the _broad Ligaments_: _They_ are fixed to the PERITONÆUM at the ILIA, nigh the _Spermatick Vessels_: Their _Figure_ is almost _Oval_, a little depressed on the _Upper Part_, where the SPERMATICKS enter. THEIR _SIZE_ is generally about half as _Big_ as _MEN_’s are; but _this_ differs according to the _Age_ and _Constitution_ of Persons: Their _Surface_ is smooth, and even in _Virgins_; but wrinkled, uneven, and dry in _old Women_: They are encompass’d with a proper strong _Membrane_, deriving its _Original_ from the _PERITONÆUM_; which also covers all the _Spermatick Vessels_. THEIR _Substance_ is Membranous and Fibrous, interwoven with a vast Number of _Vessels_; among which are some round _Vesicles_, containing a viscous HUMOUR, when boil’d, of the _Colour_, _Consistence_, and _Taste_ of the boil’d _White of an Egg_: From whence they are call’d EGGS, because of this _Analogy_. _These_ also differ in _Size_ and _Number_, according to _Age_ and _Constitution_, although (ordinarily) the _Biggest_ of them scarcely equals a PEA; and there are in _some_ Persons 10 or 12 of them, in _others_ (perhaps) but _One_ or _Two_ discernible. THE TUBÆ FALLOPIANÆ, are _Two winding Canals_, resembling _Two Trumpets_, situated on the _Right_ and _Left_ Side of the WOMB, annexed close to its _Bottom_, by their double _Membrane_; which is only a Continuation of the _exterior_ and _interior Membranes_ of the WOMB: They in _SIZE_ equal a little _Finger_ about the Middle; tho’ the _Cavity_ opening into the WOMB, will scarce admit a _Hog’s Bristle_; but the _other Extremity_, floating loose in the ABDOMEN, will admit the Point or Tip of a little _Finger_: They are of a Membranous and Cavernous _Substance_, about 5 or 6 Inches long, and have the same _Veins_, _Arteries_, and _Nerves_, as the _OVARIA_.
