very distinct kinds, the mucous gastric glands, with a cylinder 

 epithelium and the peptic gastric glands (Magensaftdriisen) 

 with cells similar to those which exist in man. A more 

 detailed description of some forms will be found in my 

 'Mikroskop. Anatomie' (II, 2, p. 1 10); and I here subjoin figures 

 of the two forms of the glands in the dog, merely to render

 whether they all secrete gastric juice or not. A few experi- 

 ments which I instituted with regard to this point, tend to
