440 E. WACE CÂRLIER 



chromatin adhères. Within the membrane the chromatin is fairly abundant, 

 dark blue tinted with red and arranged in irregular karyosomes occasionally 

 united to form long streaks. The lanthanin granules are of a fine lilac colour 

 and tend to cause clouding whilst the average sized nucleoli are being ex- 

 pelled in many cases. The nuclei measure 19.58 X 8.0 |j.. The inner ends 

 of the cells are blue grey with fine vacuolation and the lymph spaces wide. 

 In total length the cells measure 33-33 to 44.0 1^. 



Over the pyloric glands the surface cells exhibit long mucigen cups 

 which contain pale blue granules of moderate size. They do not project much 

 outwards, being flattened externally. Internally they are slightly concave 

 or straight. They measure 16.5 X 13.1 i-". 



The protoplasm between the cup and the nucleus is of considérable 

 extent, it is stained pale blue. Laterally the nuclei fill the cells, they hâve 

 deep blue walls to which very little chromatin adhères, within the envelope 

 the karyosomes are large, appear swollen and are of a violet reddish colour. 

 The lanthanin granules are of médium size and lilac tinted, numerous but 

 not clouding. The médium sized nucleoli are being extruded. The nuclei 

 measure 22,6 X 10,2 i'-. One measured in profile gave 20.3 X 5.1 (j.. The 

 inner ends of the cells are blue in colour and hardly vacuolated and the 

 lymph spaces are of médium width. Total length of cells 51 l-"-. 



9 Hoiirs after food. 



At the upper extremity of the stomach the mucigen cups are large, 

 do not project much as they are flattened externally; internally they are 

 slightly concave. Within the cups there are many pale blue mucigen gra- 

 nules of médium size amongst which a pale pinkishtin ge is discernible in 

 the lower part of the cups and also in the protoplasm between the cups and 

 the nuclei. The cups measure 19.63 X 9.43 1-^. 



The nuclei corne close up to the under surface of the cups ; laterally 

 they fill the cells and are a little uneven with thin blue envelopes to which 

 a little chromatin adhères. The karyosomes are of médium size and blue 

 without any red tint. The lanthanin granules are deep pale blue coloured 

 and numerous but do not cloud the nuclei. 



The nucleoli are small and the nuclei measure 19,6 X 7, 01 \>-. The 

 inner ends of the cells stain pale blue, are finely vacuolated and the lymph 

 spaces between them fairly wide. Cells measure 11,66 \>- in total length.
