      And though the annals of the period do not show us that there was less ale drawn, or less canary called for; men got dry with the heat of polemical discussion, and drunk with a text, not the fag end of a ballad, in their mouths; and people made a sort of morality of straight hair, long faces, and sad-coloured garments.
