Between them an injection demonstrates a dense network of 

 capillary vessels which surrounds the tube and closely invests the

 glands and the basis of attachment of the glandular cells. 



In the cardiac end of the stomach two distinct kinds of cells 

 are found in the deeper part of the gland tubes. One kind, which 

 is much the more numerous, consists of small pale spheroidal

 "chief cells" (Hauptzellen), or "central spheroidal cells." 



The cells of the other form are comparatively few, being alto- 

 gether wanting in some of the glands. They are larger and 

 more striking than the central cells, between which and the base-
