I. The Monohydric Alcohols. 
The effect of methyl alcohol on exosmosis of electrolytes was 
examined in a large number of concentrations varying from m to 10 m.

be observed that throughout, with increasing concentration, there is an 
increased rate of exosmosis. From the lowest concentrations up to mole- 
cular concentration the permeability is increased very little with increasing 
concentration ; nevertheless, in these lower concentrations increase in
