A letter from Hogarth to 'T.H.', an unidentified member of a literary society in Norwich. It includes caricatures of James Quin (1693-1766) and David Garrick (1717-79). These two leading actors of successive generations played together only during the 1746-7 season, at the Covent Garden Theatre in London. Hogarth knew and had painted both men. Garrick was tall and thin while Quin was famously short and fat. In the letter, Hogarth proposes an experiment to study the perception of proportion: 'Let the figures be doubled down so as to be seen but one at once, then let it be ask'd which representes the Tallest man'. The letter may be Hogarth's response to criticism levelled at the print after his painting of Garrick in the role of Richard III which had been published on 20 June 1746.
