Here is represented a portion of a ripe Graafian vesicle, which was upon the point of discharging an ovum. The follicle, after being dissected out of the ovary, has been subjected to slight lateral pressure in the compressorium, by which the follicle has been burst at the point (//) preparing for rup- ture. The ovisac has given way at the thin- nest point, and the ovum, surrounded by the tunica granulosa (g, 1.), and dragging after it portions of the retmacuia (g, 2.) is shown in the act of escaping from the follicle. Fig. 383. Ovum of the rabbit in the act of escaping from a rup- tured Graafian follicle. (.After Barry.) The ovum is surrounded by the tunica granulosa, g1, and draws after it the' portion of membrana granulosa termed the retinacula, #2 ; at h, where the rupture, has taken place, the coat's of the follicle are attenuated, and towards this spot numerous vessels converge. The form and size of the aperture by which the ovum escapes varies considerably. In the rabbit it generally appears in the form of a small round aperture in the midst of a bright red spot, which is margined by a little net- work of capillaries filled with blood (fig. 383. //). In the sow the aperture is generally oblong Fig. 384.
