90 Prof. Adeney and Mr. Becker on the Rate of Solution 



When the amount of air dissolved is plotted against the 

 time, the points lie as shown in figs. 1 and 2, and it will be 

 seen that they are in fair agreement with a logarithmic 

 curve. Hence the results of these experiments can be dealt 

 with in a similar way to that used in previous papers.
