I. INTRODUCTION 
This paper represents an attempt to throw some light on the 
fundamental processes in the cytomorphosis of mammalian gas- 
tric glands. A study of the literature convinces one that, in 
spite of numerous researches, there still persists a marked lack 
of agreement even as to the broader outlines, which becomes, 
with regard to more minute details, a chaotic mass of contra- 
diction, partially referable to the normal generic variations in 
the forms used, and partially, perhaps, to misinterpretation. 
It was decided, on the following grounds, to limit this investi- 
gation to the study of a single species, the pig:—First, theoret- 
ical considerations of a general, embryologic nature, lead one to 
infer that, aside from slight generic differences, the same essen- 
tial processes are probably concerned in the gastric adenogenesis
