These numbers show, at a glance, that the electromotive 

 force between the two zinc electrodes, exactly in accordance 

 with the demands of the theory, sank to smaller and smaller 

 values as the time increased, according to the law 



2 x n 2 



^ = A 1 e~H kt -B 1 e~~^ kt . 



The smallness of the coefficient B x in proportion to A 2 , and the 

 shortness of the distance L between the electrodes, had for 

 their effect that already from the fourth day the second term 

 in the preceding expression furnished to the value of E only 

 a vanishinglv small amount, and the electromotive force from
