coiicentration aucl the nature of the solution have a great influence on 

 the electromotive force. In Table VI. are the results for different solu- 

 tions of barium chloride. The figures under the heading " Calc." are 

 obtained from the formula 



allowance being made for the dissociation. The value for the ^^^ 

 normal solution is taken as the basis of the calculation ; Ii—2 and

T= 290. In Table VII. I give the figures for solutions of KCl, KBr, 

 and KI. The change of the electromotive force with the concentration 

 follows the formula
