Chapman's relationships with a number of important figures in Montreal's political and business history, between roughly 1833 and 1853, the period following Chapman's return to London.

The contract contains the terms under which Shaw and Fraser hired Wylee and his ship and crew for a commercial journey from Quebec City to the Bay of Chaleure in Gaspey (now Gaspé), and from there to Kingston, Jamaica. In exchange for carrying and unloading Shaw and Fraser's cargo, Wylee received 800 pounds and a portion of the profits from the sale of the goods.

The collection contains 164 botanical and zoological paintings created chiefly by Elizabeth Gwillim as well as possibly by her sister Mary Symonds while living in Chennai, India (then Madras). The collection includes 121 watercolours of birds with inscriptions, 31 watercolours of fish, and twelve of flowers, drawn from life rather than specimens. The paintings reflect the sisters' time in Madras during which, as artists and letter writers, they created a substantial visual record of the landscape and inhabitants of Madras and environs. The paintings also reflect Gwillim's scientific pursuits, including her study of botany.
