MR. J. N. LANGLEY ON THE HISTOLOGY AND 
PLATE 78. 
Fig. 1. X 640. Oxyntic gland, middle region of stomach. Frog (September, 1879) 
fed with sponge forty-six hours, then with worm ; killed in three hours. There 
is a small inner non-granular zone ; the cells are much diminished in size (note 
the amount of magnification), the granules are small and comparatively few. 
The sub-cubical and cylindrical cells also show marked secretory signs. 
In the actual specimens the non-granular inner zone is more distinct than in the above 
figures, since in the figures (owing to the method used to reproduce the drawings) the inner 
zone appears very finely granular instead of homogeneous ; further, in the actual specimens the 
granules disappear more from the sides of the cells than is here represented.

Gastric Glands of Triton tceniatus (Figs. 2 to 7 inclusive). 
Fig. 2. X 420. Anterior oxyntic gland. Resting state. Granules conspicuous, 
extend throughout the cells; here and there nuclei show through them. 
Nuclei and cell-substance very slightly stained. Mucous cells in necks of 
the gland tube are shown; they are less obvious than this in the freshly 
mounted specimen. Newt (February, 1879), several days’ hunger. 
Fig. 3. X 420. Posterior oxyntic gland. Resting state. The granules are smaller 
than those in the anterior glands. (Newt, September, 1879.) The granules, 
which largely hide the nuclei in the actual specimen, are not drawn here. 
Fig. 4. X 420. Posterior oxyntic gland. Four hours after feeding with worm. 
(Newt, September, 1879.) The granules are fewer, smaller, and vary more 
in size; there is a small, ill-defined outer clear zone; the nuclei and cell- 
substance stain darker. The cells are smaller. 
Fig. 5. X 440. Oxyntic gland, latter part anterior region, six hours after feeding 
Newt (July, 1879), which had long fasted. The cells have become much 
smaller, and lost all their granules ; the cell-substance stains deeply. In the 
most anterior glands in this specimen a few granules were left. 
Fig. 6. X 325. Anterior oxyntic gland. Newt (July, 1879) fed with sponge ; in 
eighteen hours sponge vomited ; killed six hours later. The zones are sharply 
marked the one from the other. (2nd type, see p. 689.) The cells are nearly 
of normal size, the granules somewhat smaller than in the normal hungry 
animal. In the actual specimen they vary more in size than is here figured. 
Fig. 7. X 280. Posterior oxyntic gland. Newt (December, 1879) fed with sponge 
forty-eight hours. The granules are small, and although they are absent 
from the outer region of the cells, yet do not form a distinct non-granular 
zone. (1st type, see p. 689.) This is an early stage of recovery. Deeply 
stained fat-globules are seen in groups in the outer portions of the cells 
(see p. 655).
