Fonds are exclusively concerned with Hebb’s work as a research psychologist and professor. Hebb's research is documented by two types of material: his correspondence, and his files on research projects. Incoming and copies of outgoing letters from ca 1934 to ca 1977 are overwhelmingly scientific in character, discussing psychological theories and their criticism, research problems, the ethics of experimentation and funding. A second section of correspondence deals with learned societies and funding organizations (1959-1977). Project files contain reports to funding bodies, and, in particular, research files and reports for Defense Research Board projects, 1950-1962 (restricted); there are also files on the administration of research grants (1964-1973), largely dealing with appointments, payroll and travel funds.

Publications - his own, and others sent to him for evaluation - are the subject of correspondence with various publishers, 1950-1977. Files of notes, correspondence, reviews, and comments concerning Hebb's own books and articles cover the years 1933 to 1971. These papers also contains original drafts for 14 monographs, articles and speeches (1941-1959), including a draft of The Organization of Behavior with Karl Lashley's comments.

Course materials, and papers by and about his students, reveal Hebb's teaching activities. Lecture notes survive for about 120 addresses to seminars, colloquia and associations (1938-1976) and there are files of lecture notes, class materials and bibliographies for McGill courses, particularly "Introduction to Psychology" (Psychology 200). About 75 slides illustrate Hebb's addresses on "Thought and Language", "Semi-autonomous processes" and other topics (ca 1962-1972). Student materials consist of files of letters of recommendation and correspondence (1947-1977) with and about students, teaching assistants, and members of Hebb's research team. As well, there are 15 original and 4 volumes of photocopied undergraduate research papers (1959-1962) and copies of 42 graduate theses supervised by Hebb (1947-1972).

Fonds concerns Pugsley’s contacts with McGill economics professors during his senior year and as a recent graduate, and his enthusiasm for McGill sports.

His correspondence comprises a letter from Prof. J.P. Day, 1934, responding to Pugsley's views on the roles of government and the banks in the extension of credit, and two letters from Stephen Leacock, one, 1934, commending a review-article by Pugsley, the second, 1935, declining an invitation to give an address. A number of clippings from the McGill Daily and city newspapers record McGill sports events, ca 1932. Two reels of film provide campus views, interior views of classrooms, and sport events at McGill.
Also includes notes and examinations for Economics classes from his student years.

The bulk of Eakins' papers concern his work as a geologist and consultant for the mining industry. His Peruvian period is covered by correspondence, reports and newsletters on the San Jose prospect for the Cerro de Pasco Corporation, 1952-1956. His work with Mineral Management Ltd. (1956-1959) is documented by correspondence on mining investments and exploration. There are also files raised by Eakins for his reports on the Axel Heiberg Island project, 1962-1969 and Eakins' participation in the first Canadian workshop on "Education in the Earth Sciences" (Sudbury 1971), and the International Geological Conference of 1972. There is also correspondence, memoranda and notes relating to the history of geology at McGill and in Québec, and some correspondence with Geology Department staff members and students.

The fonds consists of letters to Dorothy King from Cynthia Rendall Toller between approximately 1930 and approximately 1970. They detail family affairs, teaching, and rationing in England during World War II alongside various references to Canada and accounts of British National medical services between approximately 1960 and approximately 1970.

Kiang's papers cover the few years he was employed by McGill. His teaching materials include course outlines and examinations, as well as examination papers for a course in Oriental philosophy he gave at the University of Oregon Summer School in 1930. The administration of the Department of Chinese Studies is documented by requisitions and invoices for equipment and furniture, correspondence on library purchases, and letters regarding possible posts in the department, the curriculum, Kiang's salary and appointment, the Gest Chinese Library and general administrative matters. Kiang's personal files concern his work with the Hung Tao Society, his collaboration with Witter Bynmer, current events in China, and Kiang's publications and speaking engagements.

The Files papers document his activities as administrator of the Humanities Group and the English Department (ca 1946-1956, with some earlier material) and as a teacher. Administrative materials comprise about 1.5 m of information and correspondence files concerning the business of Senate, the Faculties of Arts and Science and Graduate Studies, the Humanities Group of the Arts Faculty, and the English Department. English Department material forms the largest part of the papers with files on honours and graduate students (including sessional registration forms), reading lists, examinations, awards, job applications, examination of theses, the administration of Moyse Hall, freshman orientation, and personal as well as general correspondence. There are also files pertaining to Files' work for the Montreal branch of the Humanities Association of Canada. Teaching materials consist of a large number of student essays, stories, examination papers and poems, including some by Louis Dudek and Irving Layton, ca 1937-1950. From Files' student days come lecture notes on the history of English language, 1921. There are also approximately 25 reprints of articles by Files' acquaintances and colleagues and copies of some journal and newspaper articles by and about Files.

Andreassen's papers fall into three series: personal materials, diaries, and professional files. Personal materials include family correspondence, 1929-ca 1932, and ca 30 cm of class notes and draft papers stemming from his student years, largely at Louisiana State. There are also files of private correspondence, some addressed to Mrs Andreassen, from the period 1975-1980. Andreassen's diaries cover the years 1936-1940, 1945-1952, 1962-1965, and 1968-1976. They record the working day and are interleaved with memoranda and correspondence, often of a personal nature. Professional files vary in nature with each stage of Andreassen's career, but correspondence and reports are consistent elements. To these may be added copies of surveys and inventories of the Louisiana Historical Records Survey, expense accounts and photographs arising from his work for UNRRA, records of archival deposits and drafts on an institutional history prepared as Archivist of CNR, and annual reports written as McGill Archivist.

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.
