Fig. 5 from a drawing. glands and the connective tissue is visible. In the detached part of c the glands have the character of mucous glands. At this place the mucosa of the uterus is everted as a result of the incision. If we follow on further sections the position of the placenta which surrounds the embryo proper, we find that at some distance from the embryo proper it dips into the peritoneal side of the uterus at a place above the beginning of the incisions, where therefore the uterine lumen is still intact, and it even penetrates into a fissure of the musculature of the uterus. Further downwards the embryonal placenta extends to the peritoneal tissues of the upper part of the incised uterus. Fig. i of course represents only one section while the description which we just gave is based on a study of a number of serial sections. The egg embedded itself.
