    The presence of the corpus luteum in the ovary has been con- sidered an evidence of conception; recent researches have shewn that the virgin ovary may also present a corpus luteum, but it Fig. 5* cannot exhibit the magnified characters of the gravid Graafian follicle. When the pregnant ovary is divided, the space which the follicle occupies, its enlarged cavity surrounded by a magni- fied corpus- luteum—all prove impregnation. These characters have been observed by Dr. Montgomery three months after con- ception. He has described the progressive shrinking of the sac at the sixth week after impregnation—at two days after delivery —and even in the twelfth week, when a distinct stellate cicatrix remains, very different from that in the virgin ovary. Conception may occur while the ovum is in the ovary, or in its transit through the Fallopian tube, or when it is in the uterus. Whenever it happens, increased vascular activity with corre- sponding change of structure takes place, both in the ovary and in the uterus. Those which take place in the ovary have been described; we have now to consider the changes which occur in the uterus. * Fig. 5. Corpora lutea at different periods, a. Two days after delivery. d.
