The cells subsequently formthe e})ithelium of the Graatian follicle. They may be seen arrang-ing themselves around tlie primitive ova just formed. At thehilura of the ovary the tubules (c, c, Fig. 33) have by this timealmost disappeared. As the ovaiy grows, the outermost layer of the ei)ithelialelements becomes more and more separated by the fusiform-cellstroma, and the nests of the middle layer become smaller, andfinally the arrangement and formation of the Graafian folliclesbecome completed, and in the typical epit
