Apparatus similar to Gay-Lussac's burette, with side tube at 

 top for cathode ; anode at bottom ; capacity 60 c.c. ; Ag elec- 

 trodes. In preliminary experiments with silver nitrate the loss 

 in the whole apparatus was 0.06 percent, the loss in the middle 

 portions was 0.5-0.7 percent; no diaphragms ; method of cal- 

 culation correct. 



The paper further contains a number of conductivity meas- 

 urements in confirmation of Kohlrausch's law.
