work this was expressed in terms of the area of new surface created, and a con- 

 nexion between this and the magnitude of the electrical charging was approximately 

 established. We have adopted the same method in the present work.

The results of observations made at different pressures of the sprayer are 

 shown by the graphs of fig. 3. The area of water-surface per c.c. of water 

 sprayed increases uniformly with the pressure up to a spraying pressure of about 

 11 cms. Hg., and the three samples of water behave in the same way. But at 

 higher pressures the rate of increase of surface with rising pressure is much 

 slower and different for the three samples. Thus we have the unexpected result
