THE NEWTS STOMACH DURING DIGESTION 419 



The nucleoli are not numerous, are usually of small size and sur- 

 rounded by a clear space free from lanthanin granules. No cells exhibit mi- 

 totic figures. 



Near the pyloric end, the cells are still small and the lumen wide, they 

 are not crowded with zymogen granules but many of those présent are large 

 J ,9 |i in diâmeter. The nuclei are angular and contain few lanthanin granules 

 of a fairly deep blue colour, Plate III, fig. 11. 



The chromatin which is not abundant still exhibits a reddish tinge and 

 the nucleoli vary considerably in size, many are being extruded. The cells 

 are not dividing.

Not examined owing to disease.

Near the pyloric end the lumen is small and the cells larger but not 

 crowded with zymogen granules. Thèse are of large size averaging 1,3 ix in 

 diâmeter, some small ones are also présent. The protoplasm stains pale blue 

 and the cell outlines are difficult to trace, but where visible the cell walls 

 stain as usual pale blue. 



The nuclei are somewhat plump measuringsome 11,21 i^ x 13, 97 i* and 

 hâve dark blue walls, to which however very little chromatin is adhèrent. 

 The chromatin, which is fairly abundant, has still a very slight red tinge 

 and appears somewhat spread out, in shape the karyosomes are elongated 

 and intercommunicate by fine threads, some however remain discrète. The 

 lanthanin granules are fairly numerous, but still not enough so to produce 

 indue clouding of the nucleus. They hâve a decided lilactint temperedwith 

 grey, Plate III, fig. 12. 



The nucleoli are mostly small but a few large ones are still seen in 

 process of extrusion and mitosis has again made its appearance. 



9 Hours af ter food. — Plate II, fig. 19. 



The lumen is now very small owing to the cells almost occluding it, 

 they are crowded with médium sized zymogen granules, a few being larger; 

 the protoplasm stains pale blue and appears only as a fine network between 

 the granules with which the cells are literally packed. The cell envelopes 

 are pale blue as before, though very thin and difficult to see.
