They are attached to the pos-terior layer of the broad ligament by the hilum. The ovary isa gland secreting eggs. It has, therefore, a gland-structure,stroma, parenchyma, and gland-spaces. There are, however,certain distinctive peculiarities about this gland. Its peritonealcovering exhibits a modified form of cells,—the germinal epi- THE FEMALE SEXUAL ORGANS.
