RESULTS OBTAINED. 



The results that were obtained are plotted in curves, figs. 3 to 13. The 

 freezing-point lowering.^ are plotted in figs. 3 to 6. The ordinates are 

 molecular lowerings of the freezing-point, and the abscissre are concentra- 

 tions expressed in terms of gram-molecular normal.
