![was not situated within, but on the surface of the ovary. Farre and Thompson, in England, Geofiroy St. Hilaire and Pouchet,^ in France, and Willigk^ and Hecker,^ in Germany, all support Yelpeau's position. The same views are sustained by Beclard,^ Valentin,^ and quite recently by Prof. Thomas^ of ]^ew York. This opinion is based upon the belief, that the fecundation of the ovule is impossible, unless it has escaped from the bvary, and that there is no proof that the foetus or foetal membranes have ever been found in the tissue of the organ itself. The idea seems to have been that to fer- tilize an ovufle in the ovary, the spermatozoa have to perforate the external coats of the organ, an inference which is without facts to support it. It is not difficult to conceive that the Graafian follicle might rupture, and the germ not escape. This, however, opens a channel by which the spermatozoa can reach the contents of the follicle and fecundate the ovule. When we remember the processes by which the escape of the ovule from the ovarian follicle is secured, it need occasion no surprise, that it should sometimes be retained, even after rupture of the vesicle of De Graaf has occurred. The weight of authority is in favor of the possibility of ovarian pregnancy. Unless it is concluded that M. de St. Maurice, who observed the first authentic case^ in 1682, was guilty of telling an absolute falsehood, or that he was not sufficiently informed to make his statements reliable, we must admit that he is describing a case of ovarian foetation. What- ever doubts had previously existed, they were settled by Gran- ville's description^ of an example of this form of aberrant gestation. This description and the illustration of the case appear to leave nothing to be desired to establish the existence of this ' Theorie positive de I'Ovulatiou Spontanee, 8vo., Paris, 1847, p. 421. 2 Prag.
