On the rupture of the follicle Fig. 13.—Section through the Corpus Luteum of a Rabbit, Seventy Hours post coitum. The cavity of the follicle is almost completely filled with lutein cells among which is a certain amount of connective tissue, g, Blood-vessels; ke, ovarial epithelium.— (Sobotta.) a considerable portion of the stratum granulosum remains in place, and usually there is an effusion of a greater or less amount of blood from the vessels of the theca interna into the follicular cavity. The split in the wall of the follicle through which the ovum escaped soon closes over and the cavity becomes filled with cells separated into groups by trabecular of connective tissue containing blood-vessels (Fig. 13). These cells contain a considerable amount of a peculiar
