of ]M;iL;cn schlcinulnicscn, and wrote : "The cells of the stomach surface and 
the epithel cells of the <^land tube aiul the chief cells of the pylorus glands 
are of different structure and the latter are enclosed with chief cells of the 
rennet gland." 
Similar to this result, in 1876, Bentkowsky wrote that the chief cells of 
the fundus and pj'lorus glands are a morphological homology. 
On the other hand, Langley and Sewell (1879) stated that in the dog and 
the rat the pylorus gland cells are, in a fresh condition, very clear and have 
fine granulated contents with a generally distinct Lumen. Therefore, in a 
fresh condition, they may generali)' be distinguished from the Fundus gland 
cells. 
In 1880, Heidenhein stated that, in a fresh condition, the chief cells of 
the fundus glands contain deep dark nucleuslike contents, but the cells of the 
Pylorus gland have much finer granulated contents. 
Ellenberger, in 1884, wrote that the cells of the pylorus gland are similar 
to the chief cells of the fundus gland, but are not the same. He also dis- 
tinguished the cells of the fundus gland from the superficial epithel cells by 
the fact that the former are totally coloured with carmin but that only the 
nucleus of the latter is affected. He also distinguished the chief cells of the 
fundus gland from those of the pylorus gland in that the pylorus gland cells 
are closely and finely granulated packed, compactly and that they contain some 
mucin and are easily affected by acetic acid. 
According to my own histological observations, the form antl the con- 
tents of the cells at the end part of the pylorus gland and the chief cells of the 
Fundus gland are similar, but a still more detailed comparison shows that the 
cells of the formerare of more columnar shape and are more uniformly arrang- 
ed than the chief cells of the fundus gland. 
The pylorus glands of rabbits occupy one-fifth of the gastric pouch. In 
regard to the areal proportion of their distribution this class of glands is there- 
fore not markedly different from that in the rat.
