These two curves are largely alike, due to their being those 

 of closely allied salts of the same acid ; but somewhat different 

 in consequence of difference of their metallic bases. They ar© 

 both considerably different from those of the chlorides, bro- 

 mides, and iodides of the same metals. 



12. Curves o/KCl + KI, and KCl + NaCl. 

 The measurements of electromotive force of these were 

 made to ascertain the influence of more complex compounds 

 upon the amount of that force. The salts were mixed in the 

 proportions of their molecular weights, and the proportions of 

 mixtures taken were the same as those of the same salts 

 separately in previous experiments, viz. from *1 to 1*0 grain 

 in 155 grains of water.
