I don't quite recollect how many tumblers of whiskey toddy each man drank after supper; but this I know, that about one o'clock in the morning, the baillie's grown-up son became insensible while attempting the first verse of 'Willie brewed a peck o' maut'; and he having been, for half an hour before, the only other man visible above the mahogany, it occurred to my uncle that it was almost time to think about going.
