This is true in particular of the case of twin pregnancy received from Dr. Vest. In this specimen the two chorionic vesicles, the intervillous spaces of which were devoid of blood, lay in almost the same transverse diameter of the tube and hence had distended the latter considerably. Both were implanted quite well over the entire area of contact, which included the whole perimeter of the tube. The chorionic vesicles were; flattened at the region of mutual contact, which divided the tube somewhat unequally as shown in figure 1. Although the embryo and the amnion long had disintegrated completely, and although the chorionic membrane itself is thin, covered by degenerate epithelium and also disintegrating, the epithelium of the villi not only is well preserved but is accompanied by large masses of trophoblast and considerable syncytium.

The chorionic vesicles were; flattened at the region of mutual contact, which divided the tube somewhat unequally as shown in figure 1.
