   [1913 Webster]

         It is a dispute among the critics, whether burlesque
         poetry runs best in heroic verse, like that of the
         Dispensary, or in doggerel, like that of Hudibras.

            Burlesque is therefore of two kinds; the first
            represents mean persons in the accouterments of
            heroes, the other describes great persons acting and
            speaking like the basest among the people.

      laughter, or to ridicule anything.
      [1913 Webster]

            The dull burlesque appeared with impudence,
            And pleased by novelty in spite of sense. --Dryden.
      [1913 Webster]

   3. A ludicrous imitation; a caricature; a travesty; a gross
      perversion.
      [1913 Webster]

            Who is it that admires, and from the heart is
            attached to, national representative assemblies, but
            must turn with horror and disgust from such a
            profane burlesque and abominable perversion of that
            sacred institute?                     --Burke.
      [1913 Webster]
