"‘each wild boar having his leg elevated in the air at a painful angle to show his perfect freedom and gaiety’"

An almost exact quote from 'The Pawnbroker's Shop', one of 56 pieces by Charles Dickens known collectively as Sketches of Boz (although Gibbons's quote refers to a boar rather than a boor).

The sketches, which were illustrated by George Cruikshank, were first published in book form in 1836.
