Mr Townsend, Electrical Properties of [Nov. 22, 



Table II. gives similar results for positively charged hydrogen. 



Table III. refers to negatively charged oxygen from a caustic 

 potash cell, the stream of gas being passed through F for 15 

 minutes in each experiment. 



The experiments were performed with widely different densities 



of electrification p, in order to find how the weight of the cloud 



varied with the electrification. The ratio of the weight of the 



W-w . 



cloud to the electrification is given in the last column for 



vp 5 



each experiment. The variations in p were obtained by varying 



the temperature of the cell from w T hich the gas was given off. 



Both in the case of a sulphuric acid electrolyte and a caustic 



potash electrolyte the charge on the gas which is evolved by a 



given current increases as the temperature of the electrolyte is 



raised.
