perfectly well, and he wrote about it, very wittily, in 'A PostScript Which
Should Have Been a Preface', the last chapter of his novel Waverley
written in 1814: 'most novel readers, as my own conscience reminds me,
are apt to be guilty of the sin of omission respecting the same matter of

understandably enough, to read only poetry and not a prose introduction.
