Apparatus : (i) anode and cathode cylinders connected at the 

 bottom by a tube of 0.5 mm. diameter bent seven times ; (ii) and 

 (iii) a similar tube bent three times (W-shaped). Capacity of 

 (i) and (ii) 25-30g, of (iii) 300g ; Pt electrodes ; no diaphragms ; 

 no middle portion. The weight of Ag given below is calculated 

 from the ampere-minutes. The solutions were analyzed only 

 for Pt and Sn. The method of calculation is incorrect (con- 

 stant volume of solution instead of constant amount of water). 

 Although the conductivity greatly increases, the migration num- 

 ber is unaffected by setting the solution of H2.PtC1^0 in sunlight 

 for 14 da3^s.
