(1.) The first is the entrance portion ; sometimes deep, sometimes 

 shallow, in one instance wide, another very narrow. This is the 

 " stomach cell " of English writers, the " Magengriibchen " of the Germans. 

 This depression is lined with the ordinary slender columnar epithelium 

 of the surface of the stomach. The nucleus lies far down in the cells, 

 and is of elongated oval figure (fig. 461, a). 



(2.) The second is the undermost portion of the stomach cell, or, if we 

 prefer a term made use of by fiollett, the " inner intermediate portion 

 of the peptic gland." Here (b) the cells, without departing from their

epithelial character, are broader, lower, and more granular. The nucleus, 

 a round structure, takes up about half the height of the cell. The lumen 

 of this part is usually strikingly narrowed. 



(3.) The third part now is the "outer intermediate portion" of 

 Rolktt (c). It consists of a continuous layer of peptic cells. Exter- 

 nally these are in contact with the membrana propria, and internally 

 they bound the axial canal. We have not been able to find any
