THE NEWTS STOMACH DURING DIGESTION 429 



cially in thc neighbourhood of thc nuclcus. The cells measure in total length 

 about 40 a. 



Over the pyloric glands the mucigen cups are very small, othenvise 

 they resemble those over the oxyntic glands, the chromatin is perhaps some- 

 what more abundant and a few red granules may be seen in the protoplasm 

 betweenthecupand the nucleus. Below the nucleus thc protoplasm oftencon- 

 tains many vacuoles of considérable size and may stain of a pinkish blue. 



44 Hoiirs a/ter food. 



At the cardiac end the surface cells présent long mucigen cups, convex 

 at both extremities, measuring 16,25 X 10,8 ,"■. They stain of a pale blue 

 colour of an unusual deep shade, but the individual granules are hardly 

 apparent except when stained with méthylène blue (patent B), when they 

 appear very small and numerous completely filling the cups. The cups 

 appear swollen and closely pressed together, their free ends projecting con- 

 siderably beyond the cément ring. 



Between the inner end of the cup and the nucleus there is little or no in- 

 terval, when présent the protoplasm exhibits a faint pink tint due possibly to 

 the présence of very minute granules which however could not be definitely 

 made out. The nuclei measure 19,0 X 6,7 \i., possess thick walls staining of 

 a deep blue colour owing to the chromatin adhering to their inner surfaces, 

 and appear slightly wrinkled. The chromatin is not abundant, but stains 

 very deep blue, the karyosomes are often elongated and disposed lengthwise. 

 The lanthanin is abundant but does not produce clouding, it stains pur- 

 plish grey. 



The nucleoli are neither large nor abundant. 



The inner end of the cell is long, of a blue colour with decided striation 

 and in some cases is much vacuolated especially near the nucleus. The cells 

 measure 43,3 '^ in length. 



Again in other places the mucigen cup may be concave below and the 

 distance between- it and the nucleus may be considérable and filled with 

 red staining granules. The chromatin though staining pale blue may be in 

 larger quantity and arranged in long dashes. Some nuclei are clouded with 

 violet or violet pink lanthanin granules and the nucleoli may be large. 



The cells vary so much in parts quite near together that it is practically 

 impossible to say what the typical condition corresponding to 44 hours after 

 food may be.
