A high-power view of the embryo, three sections away from the section shown in figure 23. The amnion over the dorsum of the germ disk is only partially formed. The ventral orientation of vacuoles in the latter structure and the dorsal orientation of similar structures in the endoderm are quite evident. | ||||
