VIII. neum is not a shut sac but has two distinct perforations, the mouths of the Fallopian tubes, which indirectly place its cavity in connection with the external surface of the body. § 24. The ovary is the essential secreting organ of the female sex, corresponding to the testis of the male. There are two such bodies, one on each side, as there are two testes, but, unlike the latter, the ovaries are each a completely closed sac or follicle, and, though each has its excretory duct—the Fallopian tube—this duct has no permanent connexion with its gland (as the vas deferens has.

The ovary is of an oval shape (like the testis). It lies deeply in the dorsal and lateral part of the abdominal cavity, hidden by the intestines, and en- veloped in a fold of peritoneum which forms its outer coat. The inner end of the gland is attached to the uterus by a dense cord, already mentioned as the ligament of the o
