For apparatus see Gordon, 1897 ; capacity 250 c.c. The Hg 

 cathode was surrounded by a concentrated solution of ZnClj ; 

 for the electrolyses of sodium, hydrogen, and barium chlorides 

 the anode was of Cd, for those with magnesium and cupric sul- 

 phates Cu was used. No diaphragms. The changes in the 

 middle portions are listed in the fourth column below; ig Ag 

 in voltameter ; method of calculation correct. 



The paper also contains determinations of the transference 

 in solutions of NaCl and HCl, BaCl^ and HCl, MgSO, and 

 CuSO^, in widely different proportions, the concentrations vary- 

 ing from o.i-i.om per liter. The results are in accordance 

 with those calculated from the conductivities of the salts taken 

 separately, using Rudolphi's dilution formula.

(i) The cathode vessel is attached to the top of the anode 

 vessel by means of a side tube packed with cotton wool ; capacity 

 175 c.c; no change could be detected in the middle portion;
