I also treated sarsaparilla; but as I obtained results which 
differed greatly, I shall speak of them separately.

The powder absorbed 600 grammes of water, of which it 
permitted 233 to escape.

In this experiment, I made use of the apparatus of M. M. 
Boullay ; as the liquid ran through with great rapidity, 1 was 
obliged to employ a large quantity of it.
