body of a young woman, I had from a neighbouring church-yard, and acquired knowledge enough of anatomy.
N. B. If all the pieces written upon some one part of the body, are not to be had single, the reader inclined to the delightful study of physic, will find them in the Bibliotheca Anatomica, 2 vols. folio.
Here before I proceed, I will mention a very curious case, which occurred in my dissecting the body I have spoken of. It was as remarkable an example of a preternatural structure as ever appeared.* In cutting her up, there was found two vaginas, and a right and left uterus. Each uterus had its corresponding vagina, and the uteri and the vaginae lay parallel to each other; there was only one ovarium; but two perfect hymens. The labia stretched so as to take in the anus, terminating beyond it; and as they were in large ridges, and well armed, the whole had a formidable appearance.

Most certainly there might be one conception upon the back of another at different times; therefore, I should not chuse to marry a woman with two vaginas, if it was possible to know it before wedlock.
But to proceed, — The next things I read, were the Institutes of
