The author deduced the following migration values from 

 measurements of the limiting current density at which normal 

 products appear at the electrodes and above which secondary 

 reactions occur. The third column below gives the velocities 

 in mm. per second.

The author determined the movement of one component of 

 mixtures of salts in aqueous solution. Misled by assuming 

 that the decomposition products at the electrodes indicated the 

 salt that had carried the current, he had to explain the observed 

 movement of the other salts present by the assumption of the 

 movement of non-dissociated molecules. In the following list 

 the first salt was in each case the only one measured. Many 

 cases are omitted in which only one component of the mixture 

 was indicated. For summary see Ponsot — Comptes rendus, 

 138, 192.
