Plate 4

1. Dorsal and slightly lateral view of model. X 100. Reduced. On the left the body-stalk is cut across.

2. Left lateral view of model. X 100. Reduced. On the right the body-stalk, cut in the plane of the sections, shows a large vessel; running downward and forward, also in the plane of the sections, a small portion of the amnion has been left. In the embryonic disc are seen the irregular ectodermic folds, its anterior extremity is undermined. The irregularity in the anterior part of the yolk-sac is due to a tear. The upper part of the model has been separated from the lower by sawing through it parallel with the blastoderm; it is this upper piece which is represented in Fig. 1.
