The total difference between the calculation and experiment, 
upon a reduction of the freezing point from 24°! to 4 0 , is £ of 
a degree; but the intermediate points are very irregular, and 
in an oppofite fenfe, as if the ratio were decreafing. It feems 
more probable, that fome inaccuracy in the experiments, per- 
haps owing in part to the evaporation of the lpirits, fhould be
