The double sex of single Hares, or that every Hare is both male and female, beside the vulgar opinion, was the affirmative of _Archelaus_, of _Plutarch_, _Philostratus_, and many more. Of the same belief have been the Jewish _Rabbins_; The same is likewise confirmed from the Hebrew word; [SN: Arnabeth.] which, as though there were no single males of that kind, hath only obtained a name of the feminine gender. As also from the symbolical foundation of its prohibition in the law, [SN: _Levit._ 11.] and what vices therein are figured; that is, not only pusillanimity and timidity from its temper, feneration or usury from its fœcundity and superfetation; but from this mixture of sexes, unnatural venery and degenerous effemination. Nor are there hardly any who either treat of mutation or mixtion of sexes, who have not left some mention of this point; some speaking positively, others dubiously, and most resigning it unto the enquiry of the Reader. Now hereof to speak distinctly, they must be male and female by mutation and succession of sexes; or else by composition, mixture or union thereof. [Sidenote: _Transmutation of Sexes_, viz. _of Women into Men, granted_.] As for the mutation of sexes, or transition into one another, we cannot deny it in Hares, it being observable in Man. For hereof beside _Empedocles_ or _Tiresias_, there are not a few examples: and though very few, or rather none which have emasculated or turned women, yet very many who from an esteem or reality of being Women have infallibly proved Men. Some at the first point of their menstruous eruptions, some in the day of their marriage, others many years after: which occasioned disputes at Law, and contestations concerning a restore of the dowry. And that not only mankind, but many other Animals may suffer this transexion, we will not deny, or hold it at all impossible: although I confess by reason of the postick and backward position of the feminine parts in quadrupedes, they can hardly admit the substitution of a protrusion, effectual unto masculine generation; except it be in Retromingents, and such as couple backward.
