The fonds contains Roderick Stewart's research work and writing for his biography of Dr. Norman Bethune published as Bethune (1973) and The Mind of Norman Bethune (1977).

Approximately half this material consists of letters, covering the years 1823-1837, from Andrew William Cochran, 1792-1849, civil secretary to the governors of Lower Canada from 1812 onwards, and a member of the Executive Council from 1827 to 1841. The remainder comprises a number of accounts of travels and exploration by North West Company employees, probably collected by McKenzie for his history. Included are Charles McKenzie's expeditions amongst the Otoe Missouria Tribe.; Edward Umfreville's journal of a canoe trip from Lake Superior to Portage de l'Isle 1784; accounts of the Alaskan Athabaskans, 1795 and 1805, George Keith's memoirs of the McKenzie River Department, 1807-1817; and George Henry Monk's of the Department of Fond du Lac or Mississippi, 1807; John McDonnell's account of the Red River, ca 1787; and John Johnston's of Lake Superior and a letter on the Indigenous communities of the northwest from Eneas McDonnell. Also included are letters written to McKenzie from Forks on the Mackenzie River by William Ferdinand Wentzel, 1807-1824.

The fonds consists of documents relating to Macdonald’s publications and professional activities outside the classroom both prior to and during his tenure at McGill and for various professional associations. The scope covers the period of 1976 to 2012 and includes: articles, essays, and speeches (both draft, final and off-print) and their assorted documentation (travel itinerary, correspondence, conference notes, and research).

The fonds is divided into four series which were imposed by the archivist. The first is Publications which relates to any of Macdonald’s published material. The second is Professional Activities which is composed mainly of speeches and conference notes and materials. The third is Publications and Professional Activities which encompasses any professional activity which was subsequently published or vice versa. The last is Course Materials.

His papers comprise correspondence concerning the McGill Medical Faculty from Lord Strathcona, the Victorian Order of Nurses, the Red Cross, and a Boer War Relief Fund.

The collection contains an account written by a Major Gilbert of the 1757 Rochefort expedition during the Seven Years' War. During this conflict, known as the Raid of Rochefort, British amphibious troops attempted unsuccessfully to capture the French port of Rochefort on the Atlantic coast.

This fonds contains records created by Robertson Masson & Co. as part of their work as merchants between 1835 and 1844. Robertson Masson & Co. were based in Montreal and served clients in Ontario, Quebec, and in the northeastern United States.

Records in this fonds are arranged chronologically, and are divided into files based on the year of their creation. The fonds consists primarily of business correspondence that includes information about accounts and orders, as well as financial records such as bills, receipts, and statements of account.

The greater part of the Tweed papers is course materials, composed of lecture notes in psychology, sociology, anthropology, political science, geography, history, French and English, as well as term papers and assignments (with their research notes) and examinations. There is also correspondence with McGill offices on student matters.

Professor Robert Vogel's fonds presents a mixture of his administrative, teaching and research activities from 1952 to 1994. Beside his professorial as well as administrative papers, he collected many supporting documents which helped him carry out different tasks. The series are arranged according to his position as a professor and his different administrative positions at McGill.

The series consist of:

Professor's Papers
Secretary of the Faculty of Arts and Science Papers
Chairman of the History Department Papers
Vice-Dean's Papers
Dean's Papers

Fonds consists of papers (originals and printed materials) that are largely the products of Nicholls research work; there are also some materials from his student years, and some files related to his teaching and administrative activities.

Student materials consist of notes for undergraduate and graduate courses (1931-1936) and of lectures attended during post-doctoral study at Brooklyn and Cambridge. Teaching files contain examinations and quizzes for courses taught by Nicholls (1936-1973), lecture notes for his course in organic chemistry (1952-1955), laboratory manuals, and correspondence with the Québec Ministry of Education regarding marking of High School Leaving Examinations in chemistry (1940-1949). Administrative responsibilities are documented by files of memoranda and minutes, on the business of Graduate Faculty (1960-1971), the Scholarships Committee (1967-1969), the Museums Committee (1965) and Civil Defence (1951).

Approximately half the records concern research, largely in two fields: war research, and the history of science. War research is covered by correspondence (1939-1951) with Otto Maass and other officers of the National Research Council, the Defence Department, private industry, and fellow chemists, such as Russell Smart, largely on RDX and chemical warfare. Chemical warfare is also the subject of some reading and lecture notes (1942). Drafts and published reports of Nicholls' research on RDX are supplemented by copies of other NRC and Defence Department reports on explosives research, mustard gas, and the work of the NRC Polymer Subcommittee (1942-1944). Nicholls' involvement with the Canadian Society for the History and Philosophy of Science is reflected in files of minutes, reports and correspondence (1974-1977). There are also completed questionnaires and correspondence concerning the survey of historical scientific instruments conducted by the Association on behalf of the Union internationale d'histoire et de philosophie des sciences. Files of correspondence with the Humanities Research Council largely deal with assessing grant applications for history of science projects. Other research materials include notes for a bibliography on plastics, soaps and synthetics, and a file of reading notes and correspondence with antiquarian booksellers regarding the history of espionage (ca 1930-1955). Nicholls' interest in the history of science at McGill is reflected in 1.8 m of notes and photocopies of material on individuals, faculties, and science buildings.

Fonds contains the admission cards of R.T.E. Macdonald for his complete studies in Medicine at McGill, 1878-1881. The fonds includes admission cards, a receipt, certificates and some notes from W.W. Francis.
