A manual of practical obstetrics . ourse, diagrammatic. fimbria, and to the uterus by the fibro-muscular ligament ofthe ovary, already described. Its anterior margin is attachedto the posterior surface of the anterior fold of the broad liga-ment, while the remainder of the surface, except at the hilumwhere the bloodvessels enter, is covered by the posterior layerof the same ligament. It is one inch and a half in length, 62 INTERNAL ORGANS OF GENERATION three-quarters of an inch wide, and one-third of an inch , from one to two drachms. It is an elongated, oval-shaped body, flattened from above downward, and hence saidto be almond-shaped. Its function is ovulation—that is tosay, the production, development, maturation, and dischargeof ovules. Hence the ovaries are said to be the essentialorgans of generation in the female, as the testicles are in themale. (Fig. 13, page 61, shows relations of ovary with uterusand Fallopian tube.

Structure of the Ovary.—Anatomists generally describeit as being covered on the outside by a layer of peritoneum,but microscopists have lately informed us that this externalcovering is not true peritoneum, but a layer of columnar STRUCTURE OF THE OVARY. 63 epithelium probably continuous with that lining the Fal-lopian tubes, and therefore more nearly resembling a mucousthan a serous tissue. Immediately underneath this layer is athick coat of white fibrous tissue, the tunica albuqinea. Insidethis last we find the solid substance of the ovar
