 from each other by minute processes resembling papilliB ; but the latter are 

 only met in the vicinity of the pylorus. 



The gastric mucous membrane is composed of an epithelial layer and a 

 corium, in which is distinguished a glandular and a muscular layer. The 

 epithelium is stratified and tesselated in the left compartment, simple and 

 cylindrical in the right sac, where it covers the little mucous processes 

 that separate the glandules, and penetrates more or less deeply into the 

 interior of these. 



In the left side there are found some glandular organs analogous to 

 those of the ossophagus, but the real glandular layer belongs only to the
