1898 - 99 .] Prof. Carlier on Changes in Newt's Stomach. 675 
The cells in three regions of the stomach were examined, 
namely : — 
1. The glands of the oesophageal end. 
2. The glands of the pyloric end. 
3. The glands of the narrow zone between 1 and 2. 
The shape and arrangement of the cells in these different glands 
have been sufficiently described by Langley and others, and 
require no repetition here. 
In the present communication I shall confine my remarks chiefly 
to the cells of the oxyntic glands, and when colour is mentioned, 
it refers to specimens stained with methyl-blue eosine.

The oxyntic cells are large, but do not occlude the lumen ; they 
contain numerous zymogen granules, that stain of a vivid red 
colour, and vary in size from 2 '8 g to 1 g in diameter, the majority 
measuring from 1'5 g to 2 g. Their great affinity for eosine 
points to their albuminous nature. The granules are not crowded 
together, there being plenty of room for more. Each granule is 
lodged in a tiny compartment in the pale blue protoplasm ap- 
parently containing fluid, as maintained for those of the lachrymal 
and other glands by A. Nicolas (20). It is quite impossible to 
distinguish any arrangement of these cells into zones as is the case 
with many gland cells. The nuclei are large, 10*6 g x 1 2 *8 /z, 
rather poor in chromatin and angular in outline, as described by 
Langley (13). The nuclear juice is coagulated by the action of 
the corrosive sublimate, and precipitated in the form of small 
granules of equal size, named oedematine by F. Reinke (22) or 
lanthunin by M. Heidenhain (7). These granules are not crowded 
together, and stain of a pale sky-blue colour, i.e. they are cyano- 
phile (Krasser, 11). 
The nucleoli are multiple, are not surrounded by a ring of chro- 
matin, and vary in size from minute dots not larger than lanthanin 
granules to bodies measuring 2*7 x l - 8 g. In shape some are 
rounded, others irregularly oval; they acquire a venous red tint
