among the epithelum of the Fundus gland I have never seen any. 
In the delicate structure of the Parietal cells I have seen no network as 
other histologists affirm, and the contents of the cells are always homologous. 
Parietal cells with more than one nucleus, which Trinkler found in 1884, 
and in particular the intermediary cells between the chief cells and the Parietal 
cells, which Edinger found in human beings in 1S79, ^ have not been able to 
find. 
I have seen some Parietal cells which were slightly changed by the loss 
of some of their contents and therefore resemble the chief cells of the Fundus, 
but, by staining, these can be distinguished from the chief cells. In the neck 
of the Fundus I have not been able to find chief cells, being enclosed with 
intermediary cells as related above. 
By histological observation I have distinguished the different points of 
the chief cells of the Fundus gland and the cells of the Epithelium as follows : 
The cells of the Epithelium are of high cylindrical form and firmly joined 
together. The nucleus always lies at the base and the cell membrane is very 
distinct. With luematoxin and eosin the cells of the Epithelium are more af- 
fected than the chief cells of the F undus. The form and colour reaction of the 
cells of the PZpithelium are similar to the cells of the Cardia gland. On the 
other hand, the chief cells of the Fundus gland have a more or less spherical 
form, with clear granulated cell contents. There is little or no reaction with 
eosin and hoimatoxin. They enclose the end part of the P'undus gland and 
contain many Parietal cells among them. 
The Parietal cells with two nuclei,- which, in 1895, Böhm and Davidofif 
found in this animal, I have never been able to find. I have seen, however, 
cases which, when stained with a strong congo-red, have a comparatively 
thin membrane ; the contents give a good reaction so that the wall between 
the two cells is sometimes invisible and the two appear as one cell containing 
two nuclei. When a weak staining is used with such cells, the membrane 
between the two can be distinctly seen. 
The results of the above histological abservations may be summarised as
