    Subsequent Changes in the Wolffian Bodies.—The remaining tubules of -which the posterior portion of the Wolffian body is composed, almost entirely atrophy; a few, however, remain, to the number of from nine to fifteen, and form the parovarium or organ of Rosenmuller. The Wolffian duct becomes closed and remains as a cord (Gartner's duct) running between the layers of the broad ligament, and it has been traced through the uterine and vaginal walls ; under certain conditions, however, portions of it may remain patent, dilate, and form cysts. If one of the tubes of the parovarium is affected we get a parovarian cyst; if that portion which lies between the parovarium and the uterus is dilated we have a broad ligament cyst; cervical and vaginal cysts are pro- bably derived in a similar manner (Fig. 24). Subsequent Changes in the Miillerian Ducts.—The portion formed by the union of tbeir lower ends develops into the uterus ; Figures 25, 26, 27, 28 are illustrative of the various stages in the development of the female genitalia (Schrceder). ALL, The allantois ; M, Midler's duct ; E, Rectum ; A, Depression of future anus; CL, Cloaca ; C, Clitoris ; B, Bladder ; XI, Ure- thra ; V, Vagina ; SU, S, Sinus urogenitalis. the upper or distal end of each remains patent, still communicat- ing with the peritoneal cavity; the edges of the tube become divided into fimbria?, the end assuming a trumpet shape ; this is the Fallopian tube (see 77. Fig. 24). One of the fimbriae often has a hydatid developed at its distal extremity (h'). The site of the passage of the united Miillerian ducts into the urogenital sinus becomes the vagina. It is found that from the third to the fourth month of foetal life there is no distinction into vagina and uterus, but that this occurs from the fifth to the sixth month. There is a slight descent of the ovaries, corresponding to that of the testis in the male, the round ligament being the analogue of the gubernaculum testis. This will account for the occasional passage of the ovaries through the external abdominal ring, and even into the external labium. External changes, resulting in the formation of the pudendum, Fig. 25. Fig. 26.
