124 Prof. A. J. Brown and Mr. F. Tinker. Absorption of 



absorption gradually approaches that of water as the dilution is increased. 

 When the concentration has been reduced to thirty-secondth normal, the 

 velocity of absorption of the solution is practically equal to the rate at 

 which pure water is taken up.

The Accelerating Effect of the Phenols on the Rate of Absorption is not due to 

 Disruption of the Membrane. 



It might be argued that the remarkably high velocity of absorption of the 

 phenolic solutions by the barley seeds, as compared with water, is due to the
