The Montreal Mendelssohn Choir Collection comprises several volumes of sheet music from the Choir’s library. The choral folios were compiled and bound into eight volumes at the time of their donation to McGill University in 1895. The estate of D. Torrance Fraser, a former Choir member, donated another four volumes of choral music in 1926 and 1927. Three volumes contain second copies of the pieces from the Choir’s library donated thirty years prior; the fourth volume donated in 1927 contains a number of pieces performed by the Choir but not found in the seven extant volumes from the Choir’s library.

Fonds contains diplomas, certificates from medical associations, and photographs relating to Robert Palmer Howard and Alan Campbell Palmer Howard.

This collection reflects Henry S. 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. A significant amount of the material in this collection is related to the 1837-1838 Upper and Lower Canada Rebellions (especially in Montreal), as well as events occurring immediately after the uprisings.

Consists of copies of original material, chiefly correspondence, arranged roughly by date. The contents of letters (1835-1853) include business partnerships, political reform, and personal news. Significant correspondents include Louis-Joseph Papineau, Louis-Hippolyte La Fontaine, Jacob Dewitt, François-Antoine Larocque (of Laroque and Bernard), Joseph Perreault, and Edmund Bailey O’Callaghan. There is also a partial manuscript on Canadian history and pages from a scrapbook, both dating from the 1830s.

Collection consists of six account books dating from the 1830s to the 1860s, including ledgers and daybooks, used and kept primarily by Enoch Curtis for his leather tanning business. There are also some loose accounts and notes on small sheets of paper. The ledgers use a single-entry bookkeeping method in £sd. They are organized by individual merchant account, with records of debits (purchases or expenditures made) and credits (payments or goods received). Parallel underlining and Xs indicate when an account has balanced. The collection also includes some records related to Stella Curtis from the 1890s, including one letter and two sheets of math problems marked Clarenceville Model School.
