Plate 8

Fig. 23. Photomicrograph ( x 6) of a section through the uterus and in situ placenta of a 10 mm. embryo (CX. 100). The villi are more or less equivalently developed round the whole of the chorionic sac. The decidua capsularis is still relatively thick. The distortion and dilatation of the glands in the decidua basalis, which has been irregularly penetrated by the trophoblast, are clearly shown. The thick decidua vera is well shown on the right of the illustration.

Fig. 24. Photomicrograph (x 6) of a section through the uterus and in situ placenta of a 15 mm. embryo (CX. 102). The chorionic villi are now distinctly better developed in relation to the decidua basalis and the decidua capsularis is much attenuated. The uterine glands are less apparent than in the specimen illustrated in fig. 28. The very irregular decidua basalis and the decidua vera are both much thinned.
