Apparatus : (iv) see Hittorf, 1856. In these experiments 

 a Zn anode was used and the cathode was surrounded by a 

 solution of potassium chloride ; (v) four superposed glasses of 

 which the uppermost contained the anode and the lowest the 

 cathode. The cathode was bent into the form of a U-tube to 

 permit the escape of hydrogen. Earthenware and bladder 

 diaphragms. 



In the second column are given the number of grams of 

 water in which one gram of salt was dissolved.

In addition experiments are detailed showing that in solutions 

 containing potassium iodide and potassium chloride both I and 

 CI are transported by the current.

Apparatus : (ii) See Hittorf, 1856. (iv) See Hittorf, 1856, 

 for the experiments with potassium cyanide the membranes 

 were replaced by porous earthenware ; in the experiments with 

 the alkaloid hydrochlorides the cathode was surrounded by hy- 

 drochloric acid, (v) See Hittorf, 1858. (vi) Five superposed 

 glasses with membranes. Anode of Cd in the lowest vessel, Pt 

 cathode in the uppermost. The anode was surrounded with a 

 protecting solution : potassium acetate in the experiments with 

 potassium oxalate, potassium chloride in those with potassium 

 chromate, sodium chloride in those with sodium mono- and di- 

 sodium phosphates, sodium nitrate in those with sodium phos- 

 phate and pyrophosphate and also with iodic acid ; (vii) an 

 anode vessel closed at the bottom with membranes was fitted to 

 the top of the cathode U-tube ; Pt electrodes. In the experi-
