Fig. 380. a. Ovary from a woman aged 22, h-Jw died on the tenth daij after the commencement of her last menstrual period. (Ad Nat.) A follicle is preparing for spontaneous rupture at a, where, a considerable prominence occurs, and where the peritoneal and albugineous coats are almost entirely absorbed. In general, only one follicle will be found preparing for rupture ; but sometimes two, or possibly three, may be observed in the same condition in one ovary. The growth has now been so considerable, that instead of measuring only li.'"_2£'", or even 3'", it has now a di- ameter of 5i—1'", the breadth being usually somewhat less than the length, for it rarely happens that the follicle is perfectly spherical. In consequence of this increased growth the follicle projects from the surface, and causes the swelling just described, whilst the accu- mulation of fluid within it produces a softness and sense of fluctuation in this part of the ovary, which is very obvious to the touch. Over the centre of this projection the pe- ritoneum is exceedingly thin, and in some places is wanting, partly from absorption, and partly from laceration, the result
