Plate 9

Fig. 25. Photomicrograph ( x 2-5) of a section through the uterus and in situ placenta of a 29 mm. embryo (CX. 105). The foetal-maternal junction is now very distinct and the decidua basalis is thin. The implantation in this specimen was low on the posterior uterine wall and the cervix can be seen to the left of the illustration. On the right there has been some separation of the chorionic villi from the decidua.

Fig. 26. Photomicrograph ( x 3:5) of a section through rather less than half of the in situ placenta of a 42 mm. foetus (CX. 110) and the related uterine wall.

Fig. 27. Photomicrograph ( x 4) of a section through rather less than half of the in situ placenta of a 50 mm. foetus (CX. 111) and the related uterine wall.
