IV. Experiments to determine the Effect of Tempera- 

 ture on the Rate of Solution of Atmospheric Air. 



A series of seven duplicate experiments was made within 

 a temperature range of 3°'6 to 38 0, 4 C. with atmospheric air 

 in a 15 c.c. bubble. These experiments were carried out by 

 the method described in the first part of this communication, 

 with slight modifications, and the results are given in 

 Table VI. and fig. 3.

Values of b for air plotted against temperature. 

 Formula :— 6= -0075 (T-240'l). 



Examination of these results showed that, when the 

 temperature of the water-jacket was widely different from 

 that of the room, this method did not give sufficiently 

 accurate values for the saturation-point. 



In fig. 3, the mean values of b are plotted against
