same specific conductivity, weighted with urea. During the 

 passage of the current the red layer moves toward the anode 

 with a velocity within a few percent of that calculated from the 

 conductivity of potassium permanganate.

 Berliner Inaug. Dissert. 



Apparatus: an c/3-tube ; capacity 150 c.c ; no diaphragms. 



The paper is mainly devoted to the determination of the 

 transport in aqueous solutions containing a pair of electrolytes, 

 viz. : KCl and KI ; HjSO^ andCuSO^. In addition the follow- 

 in(j results of measurements with acetic acid between Ag elec- 

 trodes are given without experimental details. "The rate of 

 transport of acetic acid seems to become constant only at dilu- 

 tions where the error of analysis is nearly as great as the quantity 

 measured."
