This collection contains a deed of assignment prepared for the firm Patterson and Co., created on 17 April 1811, with several renewals and additions, the last of which was on 22 June 1814. The deed of assignment includes many merchants and firms as attorneys or signatories, many of whom were involved in the fur trade and the North West Company.

This collection consists of letters to Sir James Craig and others on the subject of Lower Canada, 1810-1815.

These are letters from Selkirk to Miles MacDonnell, 1811-1813 and instructions concerning wages and contracts. Thirteen documents concern Lord Selkirk's conflict with the North West Company at the Red River Colony and Fort William.There is also a letter to Colonel Benjamin Walker, 1816.

Consists of letter from Lord Selkirk to Captain Benjamin Walker dated 14 June 1816 concerning the sale of Selkirk’s land at Salmon River, New York, and his impending departure for the Red River.

These papers comprise a fair copy, for the press, of "Gale on Redeemable Annuities", 1816, as well as copies of letters to his son concerning the supplement to his "Treatise on the Nature and Principles of Redeemable Annuities", 1817. Apparently neither treatise was published.

Fonds consists of a journal kept by Lord William Pitt Amherst's coachman, James Dennison, while traveling to China on a diplomatic mission to the Qing court in China in 1816. Included is an account of the loss of the ship H.M.S. Alceste in the Straits of Gaspar.

This manuscript recounts the captivity of John Knubley, Master of the Mountezumar and Alexander Scott among the Moroccans after a ship wreck in 1810.

Collection consists of 57 illustrations of birds, eggs, snakes, and plants by James Forbes chiefly to illustrate his work "Oriental Memoirs," published in four volumes between 1813 and 1815. The majority of the illustrations are either engraved or hand-drawn and then coloured, and have been cut out and mounted on paper. In many cases, a background has been drawn in and coloured or partially coloured. Approximately thirty of the images depict tropical birds, many from the Indian subcontinent, as well as some from Brazil and Australia. A number of these drawings also feature insects, particularly butterflies, and trees and flowers. Fifteen drawings depict bird eggs, including many of forest birds. The images generally contain captions by Forbes or a contemporary, identifying the subject of the drawing. Some birds are unidentified. Numerous drawings also contain species identifications or annotations in pencil by Henry Mousely, librarian of the Blacker Wood Library at McGill University during the 1920s and 1930s. These drawings are tentatively dated to approximately 1811. A note on one drawing indicates that it was originally based on drawings created during Forbes's voyages during the 1780s, then recopied in 1811. Items 44 through 57 depict snakes and reptiles and are tentatively dated to between approximately 1811 and 1818, based on a small number of drawings which are signed and dated. Many of these drawings of snakes and reptiles feature as plates in Patrick Russell's "A Continuation of an Account of Indian Serpents: Containing Descriptions and Figures, from Specimens and Drawings" (1801).

The thirteen documents are depositions taken by Lord Selkirk concerning the conflict with the North West Company at the Red River Settlement in Manitoba and at Fort William. On 11 June 1815, representatives of the North West Company attacked and fired upon the colonists, and demanded the surrender of Governor MacDonell, who, to avoid the loss of blood, gave himself up voluntarily. He was taken to Montreal as a prisoner, and charges were laid against him by his enemies, but his case was not tried. These depositions concern this case.
