CHANGES IN CELL-ORGANS OF DROSERA ROTUNDIFOLIA. 425 
Fries. 1—12 show the cytological changes in the apical gland-cells, pro- 
duced by feeding with egg-albumen : 
Fig. 1, The resting condition. 
Fig. 2. One minute after feeding. 
Fig. 3. One minute after feeding. Slightly more advanced. 
Fig. 3a. Appearance of semi-boiled white of egg, fixed in picro-corrosive 
and stained exactly like the sections. No blue colour visible. Granu- 
lation much finer than in the cells. 
Fig. 9B. Nucleus from cell, fed for thirty hours on yolk of egg. 
Fics. 13—24 show the cytological changes in the lateral superficial gland- 
cells. 
Fig. 13. The resting condition. 
Fig. 14, One minute after feeding. 
Fig. 15. One minute after feeding. Somewhat more advanced. 
Fics. 25—35 show the changes in the nucleus of the cells of the third 
glandular layer. 
Fig. 25a. Nucleus cut longitudinally. 
Fig. 258. Nucleus cut transversely. 
Fig. 26a. Nucleus cut longitudinally. 
Fig. 268. Nucleus cut transversely.
