of solution per unit area,/ = the coefficient of escape of the gas from the liquid 

 per unit area and volume, A = area of surface, and p = pressure of the gas. 



The values of b for different temperatures and different gases have been 

 found for various temperatures using a volume of water of 101-8 c.cs. and 

 an exposed area of 71 - 3 sq. cms. ; hence since 



we can calculate the values of/. The values are given in the second column 

 of Table X, and when they are plotted against temperature in each case, 

 three straight lines lying very close together are obtained, as shown in fig. 8.

Values of/ plotted against temperature. 

 Formulae :— /= -0096 (T - 236-5) for Oxygen. 

 /= -0103 [T- 240-0) for Nitrogen. 

 /= -0099 (T- 239-3) for Air.

When the values of / for any gas are multiplied by the corresponding 

 solubilities, the product gives the initial rate of solution in each case, since 

 S = fs. It will be seen by reference to Table X that the value of S is 

 practically a constant over the range of temperature given.
