In the meantime, several new vesicles make their appearance in the upper tubular compartment of the germ-cell, which eventually become cylindrical, and arrange themselves, end to end, in its interior. The four cells of the embryo now divide by hori- zontal septa, which are succeeded by others parallel to its surface, and meeting their pre- decessors at angles of 45°. The globular body which is thus formed, consists of six-
