THE GENITAL OBGANS OF THE FEMALE. 985 On the surface of this fibrous membraue is found a complete layer of cylindrical cells, which was at one time repirded as a dependency of the peritoneal serous membrane ; but it differs widely from it in an anatomical point of view. It is named the germ-epi(helliim, in order to indicate the share it takes in the production of ova durius: the early period of their development. Proper (issue.—The propter tissue, or stroma, of the ovary is more consistent than that of the testicle ; it is hard, grates on beins: cut into, and is greyish-red in colour. It is divisible into two layers, distinguishable by their aspect and structure (Fig. 529). 1. The medullar// lat/er—that nearest the hilus—is slightly red and spongy;

16 i5 SECTION" OF THE OVARr. 1, Cortical vesicles; 2, larger vesicles; 3, vesicles surrounded by tlie granular membrane; 4, 5, 6, 7, 8, follicles in various stages of development; 9, inembrana granulosa; 10, ovum; 11, cumulus proligerus; 12, non-ruptured follicle surrounded by a capillary network; 13, follicle with its contents partly escaped ; 14, stroma of the cortical zone ; 15, vessel entering by the hilus of the ovary; 16, stroma of the hilus; 17, external membraue of a corpus lutea; 18, arteries of a corpus lutea ; 19, its central vein. it is formed by an interlacing of the connective fibres, unstriped muscular fibres, and a large number of vessels that radiate from the centre towards the peripheiy. 2. The cortical lat/er has the elements of connective tissue for its base ; it is but little vascular, and contains in its substance the Graafian vesicles or follicles (ovisacs), and is consequently often named the ovit/enous lat/er. These ovisacs are in various stages of development; the smallest are situated beneath the tunica albuginea, and gradually increase as they lie deeper. When fully developed, they are filled with a transparent, citron-coloured fluid; the ovigenous layer can then no longer contain them, and they protrude more or less from the surface of the ovaiy. A Graafian vesicle, in its perfect state, is composed of an envelope and its contents. The envelope comprises : ?k fibrous membrane (tunica fibrosa), which is coiifoundt'd with the stroma of the ovary, and in it we may recognize two layers, the internal of which is rich in vessels; an epithelium, or memhrana
