The fifth Sort are call'd perfect Hermaphrodites, because they are incapable of using either of the Sexes; but some Persons fancy there are a sort of Hermaphrodites which can make use of both Sexes, and Engender both ways, though this is easily confuted, when we consider that one of the privy Parts of an Hermaphrodite is generally useless, as being contrary to the Laws of Nature, and what confusion would it be, to find in one and the same Person a Man's and Woman's Testicles, a Womb and a _Penis_? A Woman's Genital Parts and a Man's are too different to admit of such an Union, and to change the Use upon any occasion. Agreeable to the list mention'd Opinion, some Naturalists will have it, that an Hermaphrodite, which is very vigorous as to both Sexes, may Engender within himself, without the Company of another Person, having Matter to form a Child, a Place to conceive it, and proper Liquid for Nourishment: In the same manner as _Jack Hares_ engender once in their Lives, and that _Stags_ do the same, which is maintain'd by the learned _Langius_: But these Generations are both impossible and ridiculous, the Naturalists must certainly be deceiv'd, in taking some Parts of the Female for the Testicles of the Male; and what probability is there that the Seed should come out of one Part and into the other, without losing its Spirits, and altering considerably in changing of Place? And if such a Thing were possible, the Temperament that engenders Masculine Seed might as well engender Feminine, and produce the Terms at the same Time or something else in proportion to it. Women having Beards, and being a large Masculine Size, have been sometimes, by the Ignorant, accounted Men, tho' they were true Women; and it cannot be said, that one Sex is chang'd into another, for we never heard of Men that became Women, and that their, privy Parts were abolish'd; or turn'd within, in order to form the Genital Parts of a Woman. The Hermaphrodites of _Licetus_, which conceiv'd and brought forth Children, were real Women taken for Men, by reason of the length and bigness of their _Clitoris_: And the Fisherman's Wife, mention'd by _Antonius de Palma_, was only a Male, call'd the third sort of Hermaphrodites undiscover'd, which was afterwards manifested in the coming out of the Parts of a Man, when she had been fourteen Years married. The Case was the same with _Emilia_, marry'd to _Antonius Sperta_, mention'd by _Potanus_ who was accounted a Woman twelve Years, but was afterwards reputed a Man, and married again to a Woman.
