With the sketchbook turned horizontally, Turner filled the upper half of this page with studies of Coutances in Normandy, including its crumbling medieval aqueduct. Inverted in relation to the sketches above, the bottom of the page features the island-settlement of Mont Saint-Michel. Multiple pages in this volume feature sketches of these locations, a list of which is included in the sketchbook introduction. These were subsequently used as the basis for colour studies as Turner worked towards an engraved series of Channel Coast views: see Tate D25342 (Turner Bequest CCLXIII 220), D25379 (Turner Bequest CCLXIII 256).1
