Fig. 4.

The wall of the tube is quite thin, as figure 4 shows, but the implantation is fairly well preserved around the whole perimeter of the specimen.

The mucosa is destroyed throughout the greater extent of the section and the trophoblast is abundant, except in one rather degenerate and hemorrhagic area. The chorionic membrane is thin but contains some vessels distended with blood. The stroma of many of the villi also contains vessels filled with blood, but the vessels in many others are very evidently in degeneration.

The syncytium is scanty and many of the villi are very plainly hydatiform, as seen in figures 5 and 6.
