Inverted relative to the sketchbook’s foliation, the composition continues across folio 43 recto opposite (D01204; Turner Bequest XXXVII 87). This is a memorandum, probably of the picture thought to have been in the collection of the then Prince of Wales (later George IV),1 apparently a companion to that copied by Turner on folios 38 verso–39 recto (D01195–D01196; Turner Bequest XXXVII 78–79). An alternative source might be the engraved version of this picture made by Joseph Farington and published by Boydell in 1776.
