These are extensive descriptive notes of the houses and their situation and surroundings. Both are accompanied by freehand but detailed plans. They belong to the corpus of Charles Robert Cockerell's travel records as contained in the Diaries now at the Royal Institute of British Architects and the manuscript volume, an anthology of houses seen on his travels, broken up at Sotheby's in 1988 and titled Iconographia Domestica, see John Harris, Architectural History, xiv, 1971.

In 1821 Lord Lansdowne invited Cockerell to remodel and extend the Adam wing at Bowood. Some of his work survives in the present house (see D. Watkin, The Life and Work of C.R. Cockerell, London, 1974, pp.165-6).
