Fig. 52 Human Embryos

The body of Hochstetter's embryo P. 1 (Fig. 52) (No. 10 of Hochstetter's series, Fig. XIX of the Normentafel of Keibel and Elze) is already rather elongated.

The elbows have moved out from the body and the forearm makes an acute angle with the dorsal line. The fingers are beginning to become distinct on the hand plates, and tlje foot plates have become circular. Close to this embryo come those shown in Figs. 14, 15, 16, and 17 of His's Normentafel (Fig. 34, o, p, q, and r) ; in Figs. 15, 16, and 17 the thumbs are distinctly recognizable.
