Mr Townsend, Electrical Properties of [Nov. 22, 



Thus, in an experiment similar to that explained in section 15, 

 the hydrogen, instead of being bubbled through sulphuric acid 

 before entering G, was bubbled through water, and it was found 

 that when C acquired a charge of 14 per minute the inductor 

 acquired 75 per minute, whereas if a similarly charged dry gas 

 were used, G would have acquired a charge at the rate of 28 per 

 minute, and the inductor at the rate of 62. 



The same property holds in the case of charged oxygen. 

 Thus when the gas carries a cloud only 4 divisions per minute 

 were acquired by G, whereas a similarly charged dry gas would have 

 given 7 divisions per minute. The loss of charge of the clouded 

 gas in passing through a vertical tube is due to the unevenness 

 in the motion and the accidental contact of the cloud with the 

 sides. 



Diffusion. 



(22) Experiments were performed on the diffusion of charged 

 gases in order to find out whether any of the charge can pass

 these experiments is shown in figure 5. It consists of two
