The results are given in table 81. A glance at the freezing-point meas- 

 urements will show a marked increase in the molecular lowering m, with 

 increase in concentration. This would suggest at first sight that there is 

 considerable hydration in the more concentrated solutions. Such, however, 

 is not the case. When the observed molecular lowering is corrected for spe- 

 cific gravity, i. e., referred to 1,000 grams of the solvent, the observed lower- 

 ing does not differ greatly from the calculated. This is seen by comparing 

 column L' with column L, under "Hydrates," table 81. At no concentration 

 do we find as much as one molecule of water combined with one molecule of 

 the alcohol. The freezing-point data for methyl alcohol are plotted as a 

 curve (fig. 58). The abscissae represent concentrations and the ordinates 

 molecular lowering of the freezing-point.
