blue, the karyosomes are fairly numerous and arranged in dashes of some 

 size. The lanthanin granules of a deep amethyst blue are not crowded. The 

 nucleoli are small and few in number and none appear to be leaving the 

 nuclei. The nuclei measure 14,44 X ^^,25 :->•. 



The inner ends of the cells are blue grey and vacuolated. 



The cells measure 36,0 |j- in average length and hâve well marked 

 lymph spaces between them, and migrating leucocytes are fairly frequently 

 to be met with. 



One hoiir a/ter food. 



The surface cells of the cardiac end vary much in size and appearance 

 in thèse spécimens. On the whole the mucigen cups are small, especially 

 so below the level of the cément net; the inner ends are flat or concave, 

 the outer bulging less than in the previous spécimen and presenting some- 

 what i^attened tops. 



The individual granules of mucigen are not évident though the cup as 

 a whole stains pale blue. 



The cups on an average measure 10,15 X ^»32 i^.- The protoplasm be- 

 neath the cups which is fairly thick contains some very minute dust-like 

 pink staining particles. 



The nuclei are especially remarkable on account of thegreat amount of 

 wrinkling presented by their envelopes, which stain deep blue. The chro- 

 matin is almost absent except just under the nuclear wall against which it 

 forms a somewhat thick layer. The lanthanin granules are small, nume- 

 rous, and of a pinkish lilac colour. The nucleoli are also small and incon- 

 spicuous. 



The nuclei measure 11,85 X 5)48 ij., that is of very small size. The 

 protoplasm of the attached extremity of the cell is slate grey coloured and 

 vacuolated and the lymph spaces between the cells are reduced in size. 



The cells measure in total length 31,83 |j,. 



Near the pyloric end the mucigen cups are of fair size, but do not pro- 

 ject outwards to any great extent, they are convex but flattened externally, 

 straight or concave internally with mucigen of a blue colour that is some- 

 what darker towards the tip without visible granulation. 



Thèse cups measure 12,98 x 11,0 i^-- 



Between the cup and the nucleus the protoplasm which is narrow 

 contains a few red staining granules. The nucleus is of fair size with a 

 somewhat wrinkled blue stained envelope, within which a fair amount of
