To facilitate a comparison of the different types of curve and 
as a convenient summary of the main results, Figs. 7 and 8 have 
been drawn. The curves are smoothed out approximately from the 
curves obtained in different experiments, but are not intended to be 
quantitatively exact or accurately comparable. 
The powerful effect of the anaesthetic and lipoid solvent, 
chloroform, has already been referred to, and the marked increase 
of permeability caused by it affords a sufficient explanation of the 
rapid escape of water (accompanying the exosmosis of sap solutes) 
in an M/10 solution. The interpretation of the curves for the still 
more dilute solutions must remain for the present uncertain.
