Fonds primarily documents Armstrong’s social life. They consist overwhelmingly of correspondence for the period 1909-1933. Letters from his professional colleagues, such as Sir William Osler, F.J. Shepard, Edward Archibald, William J. Mayo and others in the Mayo Clinic, are concerned largely with personal greetings, association memberships, or Medical Faculty business, particularly honorary degrees. Armstrong's non-medical correspondents include Lord Beaverbrook, Lord Atholstan, Sir Hugh Allan, Arthur Meighen, George Foster and Herbert Symonds. Topics include politics, Armstrong's war work and honours, some medicals matters, and personal news. Appended to this main series are obituaries and letters of sympathy to Armstrong's widow (1933), six photographs, including one of Armstrong in an operating room, and admission cards and diplomas from Armstrong's student years.

Fonds consists of private correspondence related to Clarke’s professional work, a few musical manuscripts and texts of addresses, and a large body of personal financial accounts. His correspondence falls into two series. The general correspondence discusses arrangements for concerts in England and Canada, compositions (his own and others), the problems of musical life in Montréal, and private matters such as travel arrangements and club memberships. Much of the correspondence concerns the social aspects of music and of Clarke's position: patronage of musical events, organization of celebrations for the Jubilee of 1935 and the Coronation in 1937, and complementary tickets to concerts. Amongst his correspondents are a number of musicians and composers, including Sir Ernest MacMillan and Healey Willan. A very small percentage of this material concerns university business. A second series consists of invitations to address or attend meetings, with related correspondence. Both series cover the years 1929-1952.

Over half of the papers consist of personal financial accounts (1929-1953) for Clarke's insurance, taxes, apartment rental, various domestic expenses (e.g. groceries), telegrams, travel, and transportation.

There are two undated addresses: one on Christmas and the second on musical education. There are also two music sketchbooks from around 1920. Pictorial material comprises two photographs (approximately 1923, 1954) and a pencil sketch (1933).

Fonds consists of a scrapbook largely devoted to McGill affairs. It contains correspondence addressed both to Fleet and to other members of the McGill community such as B.J. Harrington, C.H. McLeod and A.F. Gault, largely on administrative and ceremonial business of the university. There are a few communications from J.W. Dawson, including Dawson's draft for the Peter Redpath memorial tablet. Also included are newsclippings on McGill events including numerous invitations, announcements,
addresses, programs and memorabilia from convocations, university dinners, athletic meets and musical performances.

Fonds consists of a scrapbook primarily devoted to Chipman’s diplomas and certificates, photographs and obituaries, collected between 1894 and 1947.

Fonds consists of original documents and printed materials concerning King’s research, but there is also some general correspondence, student materials, and personal papers.

Research materials comprise manuscripts, addresses, and research notes. The manuscripts and addresses (1901-1933) contain essays on fog-signals and the transmission of sound, radiation, the physics of viscous fluids, the hot-wire anemometer, astronomy, and theoretical problems. The research notes (1904-1935) comprise approximately 50 files. Eight of these concern fog-signal research (1915 1926) and include some correspondence. Other topics include radiation, physics of gases and liquids, acoustics, astronomy, electromagnetism and mathematical problems.

General correspondence covering the years 1908-1936 contains letters from his fellow physicists, including Rutherford, A.N. Shaw, E.S. Bieler and H.T. Barnes, on research and personal matters. There are also letters of introduction (1905), correspondence regarding his appointment at McGill, letters to the editor of Nature (1926), the National Research Council (1933-1934), and the Central Computing Bureau (1918). As well, files concerning ice research (1920), tests at Prescott, including his diary of the expedition (1920), and the St. Lawrence waterway (1931-1932) can be found here.

King's private papers comprise a diary for 1902, reading notes and reviews of Maria Chapdelaine (1919-1921), his pension papers, and an inventory of periodicals in his library. There are also two formal photographs and a number of snapshots of school groups, Cambridge scenes, and laboratory equipment.

Fonds consists primarily of Meek’s manuscripts of his keyboard and church music compositions, from approximately 1930-1975. Also included are programmes for his organ recitals, 1928, 1933, 1953-1957, 1960-1968, a scrapbook of clippings concerning his performance of the complete organ works of J.S. Bach, 1949-1950, and lecture notes and examinations for his McGill course in analysis, 1969-1973.

Most of the Livinson papers consist of lecture notes taken between 1905 and 1914 for undergraduate courses in philosophy, literature and history, and for courses in the Law Faculty. Two scrapbooks of clippings and photographs reflect Livinson's interest in Wilfred Laurier, approximately 1916-1949, and Abraham Lincoln, 1923-1937; there are also two 'notebooks' of clippings on books on the art of writing, memorable quotations, and speeches, 1936. Livinson's journals, sometimes kept under his own name and sometimes under the pseudonyms 'André Penuel' or 'André Charles' consist primarily of philosophical reflections and aphorisms, 1936-1942, 1947-1948, 1952. A short essay on Barbados, 1936, is accompanied by photographs, and there are also a number of photographs of Montréal scenes. Livinson's autograph collection consists of letters from prominent men, largely Montrealers, in business and government.

Photocopies of typed transrcripts of O'Brian's letters to his family during his years at McGill describe student life and amusements, as well as the perennial theme of lack of funds.

These papers contain biographical materials, such as Stansfield's curriculum vitae and testimonials in application for a professorship at the Royal School of Mines (1908), press releases on his retirement, printed biographical sketches and lists of publications. Diplomas and patents for iron ore reduction document his scientific career. His own writings comprise a dinner speech to the McGill Mining and Metallurgy Society (1936), an essay entitled "A Quaker looks at war" (1941) and a biographical sketch of William Roberts-Austen. A covering letter from John Tait encloses the latter's essay on gardening (1935).

Millen's papers fall into three series: records from his legal career, records from his business career, and files concerning McGill. Documenting his career as a lawyer are 8 cm of correspondence regarding lawsuits and court cases, interspersed with some personal matters, e.g. the affairs of the Graduates' Society (1930-1934). Appointment diaries cover the years 1931-1933. The bulk of this archive is a group of business files (1949-1970), containing accounting reports and financial statements for John Millen and Co., some miscellaneous correspondence, and clippings concerning business and politics. Millen's work for the Graduates' Society and as a McGill governor is the subject of files of correspondence, memoranda, minutes and printed material, largely on fund raising and athletics (1930-1972).
