Fig. 14. A fine hydatiform villous tree in section

No. 367. X 10.

As shown in section in figure 14, some exceedingly fine hydatiform villous trees were found among the specimens in this group. Scaffoldings or frameworks, formed by the proliferating sycytium arising from the epithelium of the chorionic membrane, were also seen. Since syncytial buds were found far out on proliferations of trophoblast which capped the villi, and also in the center of trophoblastic nodules, the origin of the syncytium from the Langhans layer would seem to be exceptionally well illustrated. In some cases a detached hydatiform villus was fastened to two portions of the tube-wall. It is well to remember, however, that these attachments may have been gained, and indeed probably were gained, before the separation of the particular villus from the chorionic vesicle.
