few cases where the nuclei are clouded and violet, the granules stain mostly 

 of a purplish slate colour. Nucleoli are small and vcry scarce. The inner 

 ends of the cells hâve a grey or reddish grey colour and somc vacuoles, be- 

 tween them are narrow lymph spaces. The cells mcasure 45,5 p. in total 

 length.

In some of the surface cells at the œsophageal end the mucigen cups are 

 small and scarcely bulge at ail beyond the ring, towards the nucleus they 

 are flattened and concave. The contents of the cup stain very pale blue and 

 no granules can be seen in them even with the méthylène blue patent B. 

 They measure 9,67 X 11,24 |j, and hâve now become shorter than broad. 

 Between them and the nucleus there is hardly any protoplasm visible, that 

 présent stains pale pink but contains no granules. The nuclei are very 

 wrinkled with fairly thick envelopes, they measure 14,82 X 6,33 f^ and 

 contain only a little chromatin of a bluish or reddish blue tint. Lanthanin 

 granules are not abundant and pale slate blue in colour, there is no clouding. 

 The small nucleoli lying in considérable sized clear spaces. In some cells 

 larger nucleoli are présent in course of expulsion from the nuclei. Below 

 the nucleus the protoplasm stains of a bluish tint with a tinge of red in it 

 especially near the nucleus and vacuoles are scarce. The cells measure in 

 total length 36,33 p.. 



Near the pyloric end the mucigen cups are small and project little be- 

 yond the cément, they are flattened externally and flat or concave internally. 

 Their contents, in which no granules are visible, stain rather deeper blue 

 than previously. They measure 11,9 X 9,75 i^- Between the cup and the 

 nucleus there is a little protoplasm of a reddish tint and the présence of gra- 

 nules in it is doubtful. The nuclear envelope is not as a rule thickened and 

 the chromatin is sparce and spread out staining purplish instead of blue as 

 previously. The lanthanin granules in some cases are small and crowded, 

 especially just within the envelope, they are lilac coloured with a decided 

 red tinge. The nucleoli are mostly small and not numerous, some however 

 are being extruded. The nuclei measure 19,34 X 7,6 .j.. The inner ends of 

 the cells are lilac slate coloured and vacuoles are rare or absent altogether. 

 The cells measure 39,23 [j. in total length and hâve very narrow lymph spa- 

 ces between them, sometimes thèse are so reduced as to be practically obli- 

 terated.
