further as to be put in rows continuous not only with the fundus glands but 
also with the pylorus glands. In reality, as stated in the foregoing pages 
and as seen in the diagramatic view given in (PI. X. Fig. 2), the cardiac glands 
are confined to a narrow belt running along the boundary ridge marking off 
the Ventriculum from the cardiac portion. Edelmann believes, in the second 
place, that the cardiac glands, the fundus glands as well as the Pyloric, are, 
as regards their distribution, different according to the species of the rats 
worked with by him, i. e. Mus documanus and Mus rattus. This is in reality 
not the case ; my present work has been carried on chiefly with M. documanus, 
and to control the facts obtained, I made use of M. rattus but was the unable 
to detect so remarkable a difference according to the species as Edelmann 
says, though repeated careful observations were made. In the third place 
and lastly, there is a wide gap between the results obtained by myself and 
those by Edelmann, concerning the transition of the pyloric portion to the 
Duodenal portion. Edelmann gives no accurate account of the structure of 
the Pyloro-duodenal passage. As given in the foregoing pages, the Duode- 
num of M. documanus shows a striking difference in the pylorus on ac- 
count of enormous aggregation of the Duodenal glands at the commence- 
ment of the intestine, while in M. rattus the pylorus gradually passes over 
into the Duodenum without any sudden change in structure. 
In 1890, Sclavunos writing on the plaster epithel of the cardiac portion of 
the mouse's stomach said that the cells lying deepest are more or less round 
and become flatter and flatter towards the top ; the nuclei show from two to 
six grains. 
It was in 1891 that a joint work by Klein and Verson appeared. The 
authors believe that the Oesophagus leads directly into the cardiac portion ; 
they considere the latter portion as a part of the former. Otherwise the 
work adds no facts to the results arri\'ed at by previous authors. 
The stomach glands of rabbits have already been studied by many his- 
tologists. In this place, I will note the chief observations only. 
In 1807, Home was the first to study the stomach of Lepus timidus and
