In these experiments, the concentrations are somewhat divergent, 
but they are close enough to suggest that the heats of solution of 
methyl alcohol in the three solvents, benzene, toluene and xylene are 
almost identical, but very different from the value obtained for the 
same substance in ethyl acetate. Also the heat of solution of ethyl 
alcohol is seen to be very different from that of methyl alcohol in 
the same solvents. To test these points further it is, however, neces- 
sary to examine solutions of varying degrees of concentration, and 
this work has been commenced. Ethyl alcohol has been examined 
in solutions in benzene, toluene and nitrobenzene, as well as to a 
less extent in phenetol. The results are expressed in the same terms 
as the foregoing.
