5. It is suggested that, with addition of water, more free ions 
may occur to conduct the current; that the protoplasts of the 
primordial meristem are in a state of gel. 
6. It is further suggested that the difference in true acidity, 
H-ion concentration of various protoplasts, may account for 
occasional different behavior of adjacent cells. 
7. The theory of electrophoresis probably accounts for the 
migration phenomena, assuming that the constituent colloidal 
particles of protoplasm bear an electric charge. 
8. Assuming an electric charge carried by such particles, it 
would follow that the particles of the cytoplasm of the cells of the | 
roots of the Canada Field Pea bear a negative charge, and that the 
chromatin particles, in some cases only, may bear a positive charge. 
The writer takes pleasure in extending thanks to Dr. W. G. 
MARQUETTE and Professor R. A. HARPER for kindly suggestions and 
criticism freely given throughout the progress of the work. The 
work was done in the laboratories of the Department of —
