WORK OF C. M. STINE. 



The values are plotted as curves in figs. 20 and 21. A diminution in the amount 

 of water present as solvent causes a diminution in the value of M. This effect appears 

 to be greater with increasing concentration. It is probable that in the most dilute 

 solutions the difference in the hydrating power of the ions and molecules affects the 

 curve, changing its direction.
