The author measured the E.M.F. between two electrodes 

 placed in a solution of zinc sulphate just after a momentary 

 current had been passed through ; the migration value calculated 

 from the concentration changes thus indicated agreed with that 

 obtained by the usual analytical method.

Apparatus like Jahn's ; capacity of anode compartment 187 

 c.c. ; Cd anode ; middle portion unchanged. The barium was 

 determined as BaSO^. The results are calculated incorrectly 

 (based on constant weight of solution instead of constant amount 

 of water).

Pt electrodes ; no middle portion ; capacity of cathode com- 

 partment 100 c.c. ; method of calculation incorrect (based on 

 constant volume of solution instead of on constant amount of 

 solvent). Further I think the number given below as the migra- 

 tion of the C^O/' ion is really that of the cation K". In the case 

 of lithium sulphate Aletter's calculation contains, in addition to 

 the two systematic errors I have already mentioned, the further 

 assumption that SO/' is monovalent. In the last column I have 

 eliminated all but the first error.
