The inner coat becomes folded, and forms convolutions, which increase and become deeper in proportion as the retractility of the external tunic increases. These convolutions in the inner and now yellow coat of the follicle are so distinct and striking (Jig, 385.) as to have suggested those comparisons with the cerebral convolutions which so many authors have employed in describing this change ; for the colour, as well as the nature and arrangement of the foldings, constituting ridges and sulci, produce an exact miniature resemblance to the surface of the brain. If the blood-clot, which is generally found contained within the ruptured ovisac, be of considerable size, its surface will frequently exhibit little furrows, more or less deep, cor- Fig. 385. Section of the ovary of a woman who was poisoned by opium. A large Graafian follicle, which had re- cently burst and discharged its contents, is laid open. The part of the ovary surrounding the aperture was loaded with vessels full of blood. The convolutions of the collapsing follicle are very distinct. The follicle is empty. (Ad Nat.) responding with the convolutions of the ovisac, by contact with which they have been im- pressed. This clot becomes adherent to the walls of-the ovisac; assumes by degrees a pale rose hue ; and gradually diminishing by absorption and contraction, it constitutes a centre, towards which the rays of the convolu- tions from all sides are directed. But if there be no considerable clot in the centre of the follicle, then its closure proceeds more rapidly. The angles of the convolutions approach each other more nearly, but there still remains a space in the centre which may be empty, or contains only the debris of old coagula. Lastly, if the cavity is empty, the retracti- lity of its outer coat soon effects its closure. The an
