Itsdevelopment varies considerably in different sections of the samespecimen. Sixth Week. The villi are now much more numerous and more still appear relatively thick. The branchings are found over agreater extent of the villi than at an earlier period. The most no-ticeable feature about the epithelium, both of chorionic membraneand of villi, is the very small amount of the deep layer {Zdlschicht \as compared with that of the superficial plasmodium. In manyvilli no deep cells can be found at all in parts, even though the coreof mesoblast may be present. Here and there in the plasmodiallayer of the chorionic membrane small vacuoles can be seen. Insome parts, also, it shows a slight tendency to split, while, in.
