The bulk of Gill's papers concern his consulting work for the mining industry and for government. Only two small files relate to his teaching career. Gill's work as mining consultant is documented by 124 maps, 48 designed by Gill himself, showing structural geology of various regions in eastern Canada, and mineral deposits of gold, iron, zinc and molybdenite, not only in Canada, but also in the Malartic gold fields in Peru (1929-1968). The papers also contain his report on iron ore in Labrador (1929) and two reports by W.F. James and J.E. Gill to the Newfoundland government, assessing prospects for gold in the Rainbow and Kayak Concessions, Labrador (1933), areas prospected by R.B. D'Aigle, see his papers, Section IX: Professions And Trades. IX). Three field notebooks record summer research expeditions (1935, 1947-1948). Three reports by Peter Eakins, a former student of Gill, describe the Malartic mine (1951, 1955-1956); there is also a report by Eakins on the Wasa Lake Goldfield (1950), and one by J.B. Gilliatt on the Wabana Iron Mines (1949). Gill also raised a file of correspondence and reports on Newfoundland mineral resources (ca 1955-1969). Finally, there are two boxes of petrographic slides, one with laboratory reports, a box of mineral samples collected for the Québec Ministry of Mines, and 4 photographs of mining concerns with which Gill was involved. His teaching activities are reflected by a file of plans, reports and memoranda on the organization of the Geology Department Map Library (1959-1969) and an outline with some draft chapters of a student's thesis (1969).

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 documents Thomson's research, his consultations with government, and his involvement in learned societies and university associations. As well, a significant percentage of the material is of a nonprofessional and private nature, focussing on Thomson as a public speaker.

Papers devoted to research consist of 18 cm of background notes, summaries and extracts on nutrition, protein and carbohydrate metabolism, and vitamins. Approximately .6 m of card indexes contain summaries of Thomson's professional reading in the 1920s and 1930s. For the 1940s and 1950s, the papers deal mainly with consulting. They consist of correspondence and reports for the Defence Department (1942- 1946), the Canadian Council on Nutrition (1946-1955) and the Canadian Council on Dietary Standards (1950-1957). Nutrition and research in this field are also the subjects of correspondence with the Royal Society, the Medical Research Council, and the Canada Council during this period. Thomson's work as a university teacher is documented by lecture outlines and examination question papers. His administrative positions led to his involvement in the National Council of Canadian Universities. These correspondence files (1946-1949) deal with academic exchange, scholarships, travel funds and conferences.

Speaking engagements are recorded by correspondence (1953-1954) and in drafts for speeches delivered between 1950 and 1961. Only a few of these discuss scientific topics; most discuss the nature of education, the relation of science to society, and of science to literature. There are also book reviews and background files of quotations and humorous poetry. Correspondence files, which Thomson generated as the Chairman of the Nutrition Committee of the Montréal Council of Social Agencies, are also found here (1939-1944).

Financial affairs, personal purchases and charities, travel expenses, and publications (particularly his Life of the Cell) dominate the private papers (1925-1963). There are also correspondence files maintained by Thomson's secretary during his last illness.

This file contains a letter from Arthur Currie presenting gift of "McGill and its Story 1821-1921" by Dr. Cyrus Macmillan to the President of the Federal Paper Company.

This subseries consists of 11 volumes, correspondence files, and a box of notecards dated from 1921-1956 relating to Wood's publication “An Introduction to the Literature of Vertebrate Zoology” published in 1931 and collection development within the Emma Shearer Wood and Blacker Libraries at McGill University. The volumes and files contain correspondence, handwritten and typed annotated manuscripts, proof sheets, the publication, notecards listing recipients of the publication, prints, printed ephemera, clippings, financial and administrative records, book reviews, and McGill Library catalogue listings related to the works within “An Introduction to the Literature of Vertebrate Zoology.” Additional professional projects are also represented in the subseries including “Coloured Plates of the Birds of Ceylon,” the Passing of John III, and Wood’s translation of Benevenutus Grassus’ de Oculis.

There are also a number of photostats of publications or manuscripts copied approximately in 1937 related to Emperor Frederick II’s “de Arte Venandi cum Avibus.” These photostats were used for reference during these research trips for Casey A. Wood and F. Marjorie Fyfe’s published translation “The Art of Falconry.”

Scott's papers comprise notes, photographs, reprints and some correspondence on Biblical archeology, particularly weights, seals and coins (ca 1920-1966).

Fonds consists of pamphlet entitled, “What to Eat to be Healthy” (Toronto: Canadian Medical Association and Canadian Life Insurance Officers Association, 1937), authored by Tisdall. Fonds also includes: typed letter signed from J. P. Crozer Griffith to Tisdall, Feb. 10, 1923, concerning a case on which Tisdall had consulted Griffith; autographed letter signed from Mrs. J. B. Gregory and Eliza J. Gregory, Aug. 2, 1920, agreeing to lease rental property to Tisdall; and autographed receipt signed from Mrs. J. B. Gregory acknowledging receipt of Tisdall’s rental payments.

Fonds contains correspondence and manuscripts. The correspondence is largely devoted to the Tait family’s property in Nova Scotia and other domestic matters, but there are also files regarding Tait’s work at McGill (1928-1942) and at the Nova Scotia Summer School in Education (1927-1941). The fonds also contains a few letters to and from Vincent Massey (1926-1940). Approximately a third of Tait’s papers are drafts of publications on practical psychology, behaviour and behaviourism, educational psychology, psychopathology and social applications of psychology. (ca 1920-1930).
