The gland reaches almost to the free surface of the stomach. Obj. T's, Oc. 2. The general course of development of the earlier stages of the gastric glands of the pig takes place in exactly the same manner as in the simpler forms already described. As early as in an embryo pig of 2 cm. total length, round, granular cells appear, differing from the remainder of the epithelial cells by their struc- tural appearance and also by their characteristic staining reaction when stained with hematoxylin and eosin. The cells lining the stomach are so closely packed together that they appear to be.
