Figure 23

The epithelium of the villi often was found single-layered without any syncytium whatever, or with at most a few syncytial buds. Nevertheless, both the syncytium and trophoblast very often show evidences of a marked activity which is not confined to implanted vilh or to the epithelium of the villi as a whole, but which may extend to that of the chorionic membrane as well. Surprisingly long, complex syncytial buds, whorls and festoons, as shown in figures 22, 23, and 24, and as said to have been observed by Frankel, often are present, especially on the villi, although in a few instances fine buds and frameworks of syncytium also were seen arising from the epithelium of the chorionic membrane. This feature (shown in figure 23) has, I believe, not been specially emphasized heretofore, though observed by Clivio (1908).
