Curve II, fig. 10, representing the value of M in the mixture of lithium bromide and 

 sodium bromide, crosses curve I, the value of M for lithium bromide in single solu- 

 tion. The same phenomenon presents itself in the case of sodium bromide at a some- 

 what greater concentration. In an earlier part of this investigation it was suggested 

 that the hydrating power of the ions alone, and of these ions when combined to form 

 molecules, would probably be different. If, now, the hydrating power of the lithium 

 bromide and the sodium bromide molecules is greater than that of the respective ions, 

 we might expect that the effect of the smaller amount of water present as solvent in 

 the mixture would be overcome by the greater hydrating power of the undissociated 

 molecules. Evidently, for this increased hydrating power of the molecules over the
