At the cardiac end the mucigen cup is long and bulges externally, 

 though not to such an extent as in the previous spécimen, the inner end of 

 the cup is also convex. The mucigen granules which are hardly recognisable 

 stain of a dusky blue colour and many threads are seen running longitudi- 

 nally in the cups. The cups measure i7,44X 1 1 ,63 i'-. The distance between 

 the cup and the nucleusisoften considérable 5,7;j. to 2,2 \>. and the protoplasm 

 contains few granules, though tinted with red. The nuclei do not appear to 

 fin the cells, thcre being an appréciable interval between the nucleus and 

 the latéral wall of the cell. The nuclei are long and narrow measuring 21,71 

 X 6,1 \j. In cross section they appear very wrinkled and surrounded by a 

 dusky blue membrane. The chromatin is in very small amount and stains 

 dusky blue, or is quite obscured by the crowded deep violet blue lanthanin 

 granules. The nucleoli are as a rule not numerous and some are of considé- 

 rable size, lying just under the nuclear envelope. Below the nucleus the cells 

 stain blue grey and exhibit longitudinal striation with numbers of minute 

 vacuoles. The lymph spaces between the cells are practically obliterated 

 and the cells appear turgid. They measure 62,56 v in length. 



Near the pyloric glands the mucigen cups are large for the région and 

 some bulge outwards considerably, some are convex whilst others are con- 

 cave internally, they measure on an average 13,0 X 13,07 i-^. They contain 

 a considérable quantity of mucigen in the form of fair sized pale blue gra- 

 nules. The cups are more ovoid in form in this région than those near the 

 œsophageal opening. 



Between the cup and the nucleus the interval is small or wanting and 

 the protoplasm contains a few faintly staining granules. The nuclei are 

 slightly wrinkled and narrow; measuring 20,38 X 5,6 p-; they hâve thin 

 dusky blue walls and little chromatin in small pale dusky blue karyosomes. 

 Many nuclei are quite clouded with violet or lilac coloured lanthanin gra- 

 nules. The nucleoli though not numerous are frequently of large size and 

 brighter red than usual, some are in process of extrusion. Below the nu- 

 cleus the protoplasm stains faintly blue or grey and contains vacuoles in 

 considérable numbers. The cells measure 50 [>■ in length and are turgid, the 

 pericellular lymph spaces being practically obliterated. 



Over the pyloric glands, the mucigen cups are comparatively large and 

 projecting, they measure 11,93X7,63 \>-. They are ail convex below and 

 filled with pale blue mucigen.
