Lumen again smaller, the cells having become of fairly large size and 

 full of small zymogen granules that do not appear to stain very deeply. The 

 cell protoplasm is pale blue in colour and fairly abundant. 



The nuclei are still wrinkled, though larger than in the previous case, 

 measuring on an average 11,10 X 13,46 a. The chromatin is fairly abun- 

 dant and no longer appears spread out or water logged, the karyosomes are 

 small and stain deep blue, some still remain adhèrent to the inner surface 

 of the nuclear membrane. The lanthanin granules are abundant, deep blue 

 grey in colour, and tend to produce clouding of the nuclei. 



The nucleoli on the whole are rather small and as usual multiple, a fair 

 number of large ones are présent also and are nearing or passing through 

 the nuclear envelope into the protoplasm where they may be still recognised 

 for a short time by their more venons tint, and larger size than the zymogen 

 granules. 



There appears to be no mitosis présent as 3'et in the glands. 



Near the pyloric end as usual the process of repair is less advanced ; 

 only some of the nuclei appear clouded, but many nucleoli are in process 

 of extrusion.

The lumen is now small and the cells are fiUed with zymogen granules, 

 those near the free extremities of the cells being somewhat smaller than the 

 others. The cell outlines and the protoplasm are difficult to see owing to 

 the number of granules in the cells. 



The nuclei are larger and deeply stained measuring 11,82 X i4,î"'S |j. 

 and contain many kaiyosomes of a deep blue colour which may be small 

 but are frequently of considérable size. The nuclear envelope appears thin 

 very little chromatin being now adhèrent to it. The lanthanin granules are 

 very crowded and stain deep blue with a decided lilac tinge, they produce 

 clouding of the nuclei, Plate III, fig. 15. 



The nucleoli are often large and are surrounded by narrow zones free 

 from lanthanin, some are being expelled. Mitosis has again begun to make 

 its appearance in the oxyntic cells. 



Near the pyloric end the cells are somewhat less advanced, fewer nuclei 

 exhibiting a cloudy appearance and no mitosis présent. Many nucleoli are 

 in process of extrusion.
