§ 58. If, in a solution containing I/I6 grm.-mol. KCl in 1000 grams of water at 

 19*5' C, we imagine the chlorine to be replaced by bromine, the process is accompanied 

 by an increase of 0'469 G-,, in the displacement of the original solution. If the operation 

 be performed upon an equivalent solution of RbCl, the increase in the displacement is 

 0*436 Gt; if the salt in solution be I/I6 grm.-moL CsCl, the increase is 0"398Gt- 

 Therefore, it appears that, when we replace CI by Br in I/I6 grm.-mol. solutions of the
