I have deduced the following migration values from the ex- 

 perimental data afforded by the work of the author ; the calcu- 

 lation is based (incorrectly) upon the change in constant volume 

 of solution, not upon a constant weight of solvent.

In this extended investigation carried out from another stand- 

 point, in no case are sufficient data afforded to permit of the 

 deduction of migration values, unless possibly in the case of 

 succinic acid (n .6 — or .3 — ?).

The author rejects Hittorf's explanation of the changes of 

 concentration during electrolysis in favor of "^that of d'Almeida ; 

 and classifies the acids according as the acidity at the anode 

 increases or decreases by electrolj'sis. 



The details of two experiments with oxalic acid are given. 

 In the first, the loss of acid at the cathode was one third of that 

 corresponding to the hydrogen collected from that electrode. 

 In the second, the loss of acid was three times as great at the 

 cathode as at the anode.
