cells parietal cells may sometimes be found. 
In the case of the pig and the horse, other histologists have obtained no 
colour reaction at all, but in the case of the rat a weak mucous reaction is 
the result which, with eosin, is still better. 
The cardiac glands of the stomach of hares and rabbits are distributed 
over a small area, being arranged in a row at the base and along the bounda- 
ry ridge ; they are consequently much fewer in number as compared with 
those of the rat, but they can be distinguished from the fundus glands by 
their histological structure. The cells of the cardiac glands are quite simi- 
lar to those of the cardiac glands of rats. 
As written above the number of cardiac glands is very small, sometimes, 
therefore, intermediary glands may be seen between the Oesophagus and 
fundus glands. From my own observation, I have never found more than 
four rows of cardiac glands along the connection of the Oesophagus and the 
stomach. 
Hinze distinguished the cardiac gland cells, the chief cells of the fundus 
gland and the pylorus gland cells by their histological structure and wrote, 
"The cells of the Pylorus gland are flat and have a nucleus at the base and 
show a good reaction with mucous colours (muci-carmin and toluidin-blue,) 
similar to the cells of the mucous gland. The cells of the cardiac gland have 
relatively larger and blister-like nuclei ; no reaction is obtained with mucous 
colour. 
The difference between the fundus and the cardiac glands is that parietal 
cells are found in the former ; the cardiac glands are affected by eosin, the 
chief cells of the fundus glands, however, very little or not at all." 
I shall have occasion, later on to write my own views on the histological 
difference between the cells of these three glands. 
(II) The Fundus Gland. 
The Fundus portion of the rat is next in size to the cardia sac and is 
connected with this by the cardiac glands. The tube of the fundus gland may
