The syncytium is excessive. The mesoderm of chorion andinclosed vesicle is very fibrous. There are blood islands and. Fig. 58b.

Within the stem there is a sharply defined cavity linedwith epithelium and an hour-glass-like space filled with blood. Onone side the stem is covered with epithelium. Fig. 58c.—The cavity of the stem, shown in Fig. 58b, enlarged 50 times. a cavity lined with epithelium in the stem of the vesicle. Themain portion of the vesicle is composed of two layers, butnear the stem there are three layers present. The mesodermof the villi is hyaline and cedematous, and between them thereis a stringy mass of mucus or fibrin rich in leucocytes. i66 MALL. [Vol. XIX. No. 60. Embryo, C. R., 8 mm.
