For apparatus see Wiedemann, 1856; capacity no c.c. ; no 

 diaphragms. The siphon became considerably heated. No 

 middle portion ; anode Cu, and cathode Pt. 



The calculation is incorrect (based on constant volume of so- 

 lution, not constant amount of water).

Die Bestimmung der Ueberf uhrungszahlen der lonen f iir Lithium- und Kohlen- 

 saureverbindungen. Wied. Ann., /j, 289; Dissert. Breslau. 



Apparatus : (i) superposed glasses ; diaphragms of gold- 

 beaters' skin. The Pt cathode was surrounded by free acid, 

 the anode was of Cd ; the middle portion was tested for free 

 acid and for Cd. (ii) a U-shaped cathode tube with three 

 superposed glasses ; capacity 25-60 c.c. ; Pt electrodes. In the 

 experiments with the carbonates the middle portion was tested 

 for neutrality by litmus after precipitation by barium chloride. 

 For the experiments with the caustic alkalis, porous earthen- 

 ware was substituted for the diaphragms of gold-beaters' skin. 



The method of calculation is correct.
