A Case of this Nature is cited by _Diemerbroeck_, which happen’d in the Time of _Ferdinand_ I, King of _Naples_; it was of two Children, who were call’d _Carola_ and _Francisca_, and were reported to have changed their Sexes upon the Appearance of Beards growing on them, which their Mother gave out was miraculously done, upon which she changed their Habits for those of Men. The Story reached _Fulgosus_’s Ears, and he wrote it confidently and securely, and yet our Author _Diemerbroeck_ discredits it very much, since the Rumour proceeded from the Mother and no other Witness, with whom the rational Part of the World must concur. _Johan. Bauhin._ furnishes _Skenckius_[37] with a History of a young Man, who was thought to be a Girl, by all his Acquaintance; because he sat in the Manner of Women to make Water, which was occasion’d by the Glans Penis’s being imperforated, and having a Passage for Urine under the Penis; he lay with Women and was dress’d and employ’d as one all his Life; and dying of a Pestilential Disease, was, by order of a Magistrate, open’d, and found to be a perfect Man in all respects, without any Part proper to the other Sex in the least. In all probability, if he had been detected, when alive, he would have pretended a miraculous Change of Sex as did the Mother of the above _Carola_ and _Francisca_. There[38] was an Opinion amongst the _Greek_ and _Arabian_ Physicians, concerning a great Analogy between the Male and Female Genitals as to their Structure, who strenuously assert, that these differ in nothing but their Situation, that is, they compare the Cervix and Vagina Uteri to the Penis, and the Fundus to the Scrotum, only they are inverted or rather not protruded, and that which hinders their Protrusion in Women, according to these Authors, is the want of Heat and sufficient force of Nature. It would be a Digression from our present Purpose, if we should enter upon a comparative View of the Parts of Generation of both Sexes, and endeavour to confute those Chimeras, and therefore the Use that is at present necessary to be made of this Opinion, is only to shew that this was another Origin from whence these Reports of such Metamorphoses have sprung and been encouraged, as well as any of those others already taken notice of. For admitting that Hypothesis, _viz._ that every Woman is a Man, if she had but heat of Temperament and Strength sufficient to drive the inside of the Uterus, _&c._ outward, and that that Inversion should form a Penis and Scrotum, which was the general Notion amongst some of the Learned a long time after _Galen_; I say, admitting this was now the reigning Notion, we should upon the least Appearance of any thing strange in the Parts of Generation, be as ready still to acquiesce to any Rumour of the Change of Sex, _&c._ as ever, having so easy a Manner of accounting for it, as the _Calor eximius & Naturæ Vis_, which was the fashionable Cause to which Changes of this Nature were always ascribed,
