Portion of human stomach (magnified 30 diameters) cut vertically, both in a direc- 

 tion parallel to its long axis, and across it (altered from Brinton). 



The gastric glands of the human stomach (magnified), a, deep part of a pyloric 

 gastric gland (from Kolliker) ; the cylindrical epithelium is traceable to the csecal

 tion of a small portion of the mucous membrane with the glands magnified 30 diame- 

 ters ; c, deeper portion of one of the glands, magnified 65 diameters, showing a slight 

 division of the tubes, and a sacculated appearance, produced by the large glandular 

 cells within them ; d, cellular elements of the cardiac glands magnified 250 diameters.
