Adeney and Beckek — Solution of Nitrogen and Oxygen. 403 



From the graph of -- against w, we can obtain the initial rate of solution 



into air-free water. 



In the diagram (fig. 8), the intercept OA gives the total amount of air 

 absorbed which agrees closely with that calculated from direct observations.

The intercept OB gives the initial rate of solution at the beginning of the 

 experiment. To obtain the actual rate of solution into air-free water, we 

 must continue the line AB back to meet an ordinate through C, where 00 

 is the quantity of air in solution initially. Then CD represents the initial 

 rate of solution into air-free water.
