The mucigen cups at the cardiac end contain numbers of large blue 

 granules, but there is no crowding of them. The outer ends of the cups pro- 

 ject considerably whilst the inner ends are convex. Between the cups and 

 the nuclei there is a fair amount of bluish protoplasm without granules. The 

 nuclear envelopes are dark blue with some chromatin adhering to their inner 

 surfaces; within this the chromatin is fairlyabundant, the karyosomes large, 

 angular and tending to become united together. Lanthanin granules are 

 large, abundant, but not crowded, they stain dark blue grey. The nucleoli 

 are small and the inner ends of the cells pale blue with few vacuoles. 



Near the pyloric end the cells are similar to thèse at 15 hours but the 

 protoplasm is grey with apinkish tinge instead of red. The lanthanin granules 

 cloud mostof the nuclei and stain of a lilac colour; the nucleoli may be 

 very large and in process of extrusion. 



17 Hours af ter food. 



The mucigen cups appear large and somewhat swollen and contain blue 

 granules that are numerous though not crowded. The cups are rather flat 

 externally, though they project to some extent at the cardiac end of the 

 stomach ; internally they are flattened or convex and measure 16.6 X 15. Qi^. 

 Between the cups and the nuclei the protoplasm is évident enough and of a 

 decidedl}' red tint, with a few red staining granules in it. The nuclei are 

 large with smoth walls and appear slightly swollen; they measure 20.43 x 

 10.15 [j-. Their envelopes are blue with some adhèrent chromatin, within the 

 envelope the karyosomes are fairly numerous, small or large as the case may 

 be, united by bands or even forming streaks. The lanthanin granules are 

 large, numerous, even crowded in some cases and blue in colour, they pro- 

 duce no clouding however. The nucleoli are of some size. At their inner end 

 the cells are blue or blue grey, fibrillated but not vacuolated and between 

 them the lymph spaces are of moderate size. Total length of cells 53.3 1^. 



At the pyloric end the mucigen cups are also large and contain large 

 blue granules without crowding, they project a little externally and are con- 

 vex at both extremities. Between them and the nuclei the protoplasm is wide 

 and grey without red granules. The nuclei are large with blue envelopes. 

 The chromatin within the nuclei is as a rule in large compound blue karyo- 

 somes. The lanthanin granules are large, purplish in colour but rather spar- 

 sely arranged. The small nucleoli are conspicuous and numerous. Between
