This shows that p = a . • Hence we have from equation (2) § 9 



(13) The velocity of the charged carrier when acted on by an 

 electric force can be found from the above numbers. The electro- 

 meter having been standardized, it was found that '0037 electro- 

 static units of quantity would give a deflection of one division on 

 the scale, so that we get 



32 x -0037 9 ,__3 



in the hydrogen experiments, and 



49 x -0037 

 ^ = 7^S-^302 = 310 



in the oxygen experiments. 



Let k h and e H denote the values of k and e for hydrogen and 

 k and e similar values for oxygen, and we get 



^^ = -0043, where o Q = 2-10" 3 , 



and 4<7rpoeo = . 002 5 5) wne re p = 3-10- 3 .

Hence - ff = 5-6, and ^ = 15 (1). 



From the equation kV = Fe, which is similar to the equations 

 (1 ) § (9), V being the velocity due to an electromotive force F, 

 Ave obtain for the motion of the charged carrier in hydrogen 



F

and for the motion of the charged carrier in oxygen

 V= .

Hence under an electromotive force of 1 volt per centimetre, 



the hydrogen carrier travels at the rate of ^r— =-7; centimetres
