It is seen from the above table that the differences, although always positive, vary 
to a most marked extent in the case of the alcohols as compared with simply consti¬ 
tuted liquids.

The large value of the difference given by the comparison of normal propyl and 
allyl alcohols is a further instance of the peculiarities of the alcohols.
