John Abernethy. Coloured etching by Cruikshank, 1828.

A hand-coloured etching—line bitten in acid, then tinted by workshop colorists—shows a dinner-table confrontation between an overdressed, overfed family and a lecturing physician. The caption identifies the scene as A Practical Lecture on the Digestive Organs by the Eccentric Doctor A-B-E-Kn-e of Thigh, targeting the real surgeon John Abernethy, famous for haranguing wealthy patients about their gluttony. A red-faced man slumps at table, a beribboned woman swoons, a small child peeks from behind furniture. The class ridicule cuts both ways: Abernethy's rudeness and the gentry's excess are equally mocked. This vein of crowded, speech-ballooned, sequentially readable satire—directly inheriting Hogarth's narrative tableaux and Gillray's grotesque physiognomy—fed directly into the newspaper comic strip and the modern comic book panel.
