Recorded by Jackson (Dictionary), who mentions that Dulfield, a painter on glass, is stated in a paragraph in the London Chronicle (21 April 1759) to have ’lately died' at Brentford. This reference was taken from MSS by F. and G. B. Buckley, now housed in the library of the Victoria and Albert Museum, London. Presumably Jackson supposed that Dulfield painted silhouettes on glass because he was esteemed, she tells us, as the greatest artist then painting on glass in Europe. My own comment is that an artist who died in 1759 would have lived during a period when few silhouettes were painted on glass. Possibly the date '1759' was miscopied from '1789'.
