As can also be seen, the effect increases somewhat more 
slowly with an increase in concentration than does the con- 
centration itself. In Table VIII the concentration is over 
three times as great as that in Table V; the effect of the 
alkali, however, only three times as great. 
We must now try to answer the question which is of
