Marlborough's letter from Blenheim [Woodstock, Oxfordshire], 9 November 1796. [von Brühl's notes from Harefield, circa 1796?]
A Fellow of the Royal Society, Marlborough's main scientific interest was astronomy, a subject on which he corresponded with von Brühl. The four items in good condition, with light signs of age and wear. They are accompanied by a typewritten (1960s?) report (3pp., folio), whose purpose is to disprove any connection between them and 'the name of Henry Cavendish and his work on the barometer'.
