Phenolic Solutions by Seeds of Hordeum vulgare.

But, in spite of this general increase in the velocity of absorption, the 

 relative rates at which the solutions are taken up remains the same at 

 B2-2° C. as at the lower temperature. All the phenolic solutions, with the 

 exception of pyrogallol, are absorbed at a greater rate than pure water.

(c) Seeds in Solutions of Ordinary Phenol of Various Concentrations at 

 26 - 6° C. — As might be expected, the accelerating effect of phenol on the rate 

 of absorption is diminished when the amount dissolved is diminished. This 

 is shown in Table III and the corresponding diagram. The accelerating 

 effect is most marked in the case of seminormal phenol, and the rate of
