An irregular cavity is thus at first left in the interior ofthe ovisac,, after the discharge of the ovum; but this gradually diminishes,partly in consequence of the increased growth of the yellow substance, andpartly owing to the general contraction of the ovisac, until it is at last nearlyobliterated or reduced to a sort of stellate cicatrix (e—h). An effusion ofblood usually takes place into this cavity, in the Human female, at the timeof the rupture of the ovisac; but the coagulum which is left takes no sharein the formation of the yellow body. It generally loses its colouring matter, 3 L.

The latter part of the history of the Corpus Luteum is greatly in-fluenced by the impregnation or non-impregnation of the Ovum whose impregnationFig. 316.
