The folds into which the membrane has been thrown continue to increase in size, from theproliferation of their cells, until theyunite and become adherent, and eventu-ally fill the follicular cavity. By thetime that another Graafian follicle ismatured and ready for rupture thediminution has advanced considerably,and the empty ovisac is reduced to avery small size. The cavity is nownearly obliterated, the yellow color ofthe convolutions is altered into a whitishtint, and on section the corpus luteumhas the appearance of a compact whitestellate cicatrix, which generally disap-pears in less than forty days from theperiod of rupture.
