EXPLANATION OF COLOURED PLATE. 
The figures are semi-diagrammatic, and represented as stained with 
methyl-blue eosine. 
I. Oxyntic cell of newt in a resting condition. 
II. Similar cell after secreting for twenty hours. Taken from a winter 
newt. 
III. Similar cell forty-four hours after the commencement of secretion ; the 
nucleus is filled with deeply stained lanthanin granules. 
IV. Similar cell sixty-eight hours after the commencement of secretion. 
The lanthanin granules exhibit an intermediate coloration, and the nucleolus 
is very large. 
V. Oxyntic cell of summer newt half an hour after commencement of 
secretion. 
VI. Similar cell one and a half hours after commencement of secretion. 
The chromatin stains of a pale colour, and the nucleoli are increasing in size. 
VII. Similar cell three hours after commencement of secretion. The 
chromatin now stains red, and cell is practically exhausted. 
VIII. Similar cell five hours after commencement of secretion. The 
nucleus is full of deeply staining lanthanin granules, and the cytoplasm stains 
of a reddish tint. 
IX. Similar cell six hours after commencement of secretion, showing an 
extruded nucleolus lying in the protoplasm. 
X. Similar cell eight hours alter commencement of secretion. Increase in 
quantity of chromatin, lilac coloured lanthanin, and large nucleolus. 
XI. Similar cell nine hours after commencement of secretion. The cell has 
almost returned to the resting condition. 
EXPLANATION OF PHOTOGRAPHS. 
These photo-micrographs were all taken with a magnification of 600 linear. 
1. Oxyntic gland from near oesophagus in which the zymogen granules are 
of large size. 
2. Oxyntic gland twenty-four hours after food. 
3. T. S. oxyntic gland forty-four hours after food. 
4. T. S. oxyntic gland sixty-eight hours after food. 
5. T. S. oxyntic gland 114 hours after food, showing early stages of mitosis 
in the cells. 
6. Oxyntic gland three hours after food, from near the pyloric end. 
7. T. S. oxyntic gland fifteen hours after food, showing extrusion of 
nucleoli. 
8. An oxyntic cell in process of mitosis.
