The spermaticartery is originally a branch of one of those which go to the Wolffian body, and. 908 UEINAEY AND GENEEATIVE ORGANS. ascend from the surface of the Wolffian body to the upper part of the testis,along the ligaments connecting them ; but, as the testis descends, the artery liesentii-ely above it, the secreting substance of the Wolffian body remaining ad-herent to it; and hence it is that the organ of Giraldes, which consists of per-sistent Wolffian tubules, is found in a position superior to the epididymis. (Banks,No. 290). The Descent of the Testicles. —The testicles, which are originally situated inthe abdominal cavity, pass down into the scrotum before bii-th. The testicleenters the internal inguinal ring in the seventh month of foetal life : by the endof the eighth month it has usually descended into the scrotum, and, a short timebefore birth, the narrow neck of the peritoneal pouch, by which it previouslycommunicated with the general peritoneal cavity, generally becomes closed, andthe process of peritoneum, now entirely shut off f
