This is one of a group of watercolour studies of Thames scenery that occupy some of the later folios of the sketchbook; see chiefly 38 verso (D05833) and Introduction to the book for comment. Edward Croft-Murray, in a pencil annotation to a copy of Finberg in the Tate Library, identified the subject as ‘Thames near Kew’ while Hill, acknowleding the difficulty of precisely locating the site, suggests Richmond/Isleworth/Kew. He compares the scenery to a watercolour also of an unidentified stretch of the Thames dating from about 1806 (British Museum, London)1 but there seems no particular connection.
