The results obtained show that the magnitude of the osmose varies 
with the magnitude of the potential. The magnitude of osmose will not 
vary directly with the magnitude of potential inasmuch as the electromotive 
force values must overcome the tendency toward positive osmose, and, also, 
the value of the double electric layer of the capillary wall system is differ- 
ent in every solution used.
