A pen and ink drawing for The Reward of Cruelty, the fourth scene in Hogarth's Four Stages of Cruelty. The body of the criminal Tom Nero is shown being dissected for an anatomy lesson. Loosely incised with the stylus and stained red, especially where the stylus cuts through to the verso, showing that the sheet has been reddened for transfer.

This drawing is probably preparatory for the woodcut by John Bell which was published on 1 January 1751, just ahead of Hogarth's engravings of the full series, which were published on 21 February 1751. Hogarth changed the composition significantly before either the woodcut or the engraving was made, adding a seated chief surgeon in the centre background and changing the clothes and poses of some of the figures surrounding the dissection. The hatched brushwork may have been intended as a guide for the wood cutter, but in some places is replaced with wash.
