CHANGES IN CELL-ORGANS OF DROSERA ROTUNDIFOLIA. 421 
The Cytoplasm stains very pale bluish purple. 
The Nucleus is almost spherical, and stains very pale blue- 
purple. 
The Nuclear Chromosomes are conspicuous deep blue 
granules of various sizes, and considerably larger than in the 
control. 
The Nuclear Plasm stains reddish purple, and is gathered 
together in the centre of the nucleus, instead of being distri- 
buted in chains. It is still apparently granular. 
The Nucleolus is pale red, and much smaller than in the 
control (fig. 25). 
Effect on the Cells of the Third Glandular Layer 
of Stimulation for One to Four Hours. Fig. 31. 
The Cell Wall and Cytoplasm are as in the last type. 
The Nucleus is oval, spherical, or irregular in shape. It 
stains a more or less intense blue, sometimes very deeply. 
The Nuclear Chromosomes are conspicuous dark blue 
granules. 
The Nuclear Plasm is scanty and granular, staining reddish 
purple. It is collected to form a little cloud round the nu- 
cleolus. 
The Nucleolus stains purplish red. It has a transparent 
appearance, and contains one or more endonucleoli.

Cells of the Third Glandular Layer. Fig. 82. 
The Cell Wall, Cytoplasm, Nucleus, Nuclear Chromosomes, 
aud Nuclear Plasm as in the last description. 
The Nucleolus is purple-red, and is indistinct because it 
agrees in colour with the granules which closely surround it. 
One or more endonucleoli are present. In the figured speci- 
men the endonucleolus is large.
