Political, business, and personal correspondence. The letters are mostly addressed to Henry S. Chapman (nine letters), with others addressed to Thomas Falconer (five letters), Samuel Revans (four letters), Chapman and Falconer (one letter) and D. Daly, possibly Sir Dominick Daly (one letter). The creators of the letters include Edmund Bailey O'Callaghan (seven letters), François Antoine LaRocque (5 letters), Louis-Hippolyte La Fontaine (four letters), Jacob DeWitt (one letter), and Claude Perrault (one letter). The earlier letters chiefly concern business interests, including the establishment of a Canadian Company house in London, as well as the partnership between LaRoque and Revans. The letters from 1837 and 1838 have a much more informal tone, and focus on political reform and the events during and following the Upper and Lower Canada Rebellions of 1837-1838.
