422 LILY HUIE. 
Effect of Stimulation for Twenty to Thirty Hours 
on the Cells of the Third Glandular Layer. Fig. 33. 
The Cell Wall.—The external wall is pale blue; the internal 
wall is deep blue. 
The Cytoplasm is very scanty. It stains a very pale blue, 
thus differing in a very marked manner from that of the other 
gland-cells. Sometimes there is a trace of red, or an appear- 
ance of a few red granules here and there. 
The Nucleus is irregular in shape, and stains pale pinkish 
purple, and apparently quite homogeneous. 
The Nuclear Chromosomes consist of a number of dark blue 
granules of varying size which are peripherally placed. 
The Nuclear Plasm is altogether absent, at least no granu- 
lation can be made out, only a diffuse stain. 
The Nucleolus is pale red and transparent-looking. It 
possesses one or more endonucleoli. 
Cells of the Third Glandular Layer Two to Three 
Days after Feeding. Fig. 34. 
The Cell Wall.—The external wall is pale blue, the internal 
wall deep blue. 
The Cytoplasm stains pale blue. 
The Nucleus is irregular in shape, slightly oval, and stains 
blue. 
The Nuclear Chromosomes occur as a number of scattered 
granules, each apparently double. 
The Nuclear Plasm consists of blue granules, arranged in 
rows. It is rather scanty, and stains much less deeply than 
the nuclear chromosomes. 
The Nucleolus is large, stains purplish red, and contains one 
or more endonucleoli.
