W.H. Helfand, 'Medicine and pharmacy in British political prints: the example of Lord Sidmouth', Medical history, 1985, 29: 375-385, p. 376 ("The print is a parody on the physician Dr Sangrado in the popular French romance by Le Sage, Gil Blas. Addington is again the doctor bleeding John Bull, who sits on a commode labelled "Reservoir for the Clysterpipe family!". The print has a double purpose-to protest the level of taxes necessary to support the war with France that had temporarily been halted and to comment on the lucrative sinecure Addington had obtained for his then sixteen-year-old son, to which the words "Clysterpipe family" refer. Both of these prints relate to taxation, for the theme of John Bull being treated, and particularly bled, by physicians is one of two classic formulas for such events, the other being John Bull crushed under the burden.")
