When an electrolyte is decomposed by the passage of a 

 current, then according to Faraday's well-known laws of 

 electrolysis the amount of salt decomposed is proportional 

 (1) to the amount of electricity carried, and (2) to the che- 

 mical equivalent of the salt. Thus we see that the above 

 results, which show (1) that the maximum amount of elec- 

 tricity transported by a salt-vapour is proportional to the 

 amount of salt passing between the electrodes, and (2) that 

 the saturation current with a definite amount of any salt 

 passing between the electrodes is inversely as the chemical 

 equivalent of the salt, amount to a proof that Faraday's laws 

 of electrolysis apply also to the saturation current carried by 

 a salt-vapour. 



To show that the analogy between salt-vapours and electro- 

 lytes is complete, it remains to show that the factor of propor- 

 tionality in the second law is the same for both. To decide
