Campbell's papers contain some students materials, a small amount of correspondence, and commemorative materials associated with his retirement in 1950 and his 75th birthday in 1961. Student materials consist of mimeographed lecture notes for a course by Dr. J.C. Meakins, with Campbell's handwritten notes. The subjects covered are heart and lung diseases and the nervous system. Correspondence consists of a letter from Lady Drummond offering the services of the Canadian Red Cross Society to Campbell, 1917. A volume of photographs and biographies of doctors and nurses connected with the Department of Obstetrics and Gynaecology at the Montreal General Hospital, 1883-1950. was assembled by Campbell himself. Also included is 4 cm of correspondence and questionnaires, largely from former interns and residents who had served under Campbell's regime. An album of letters from former colleagues and friends commemorates Campbell's 75th birthday, 1961.

Fonds consists of originals, carbon and photocopies stemming from both the wartime and post-war phases of Currie's career. His wartime career is recorded in a copy of his battlefield diary for 2 June 1916- 8 February 1917 and commemorated in an album of signatures of the officers he commanded. Postwar materials comprise correspondence and speeches. The correspondence concerns various causes which Currie patronized and books for which he wrote introductions. His speeches (in 7 volumes, with some loose) are devoted to the war and its aftermath, politics, education, eulogies, speeches of welcome, Christmas and New Year's messages, dedications of war memorials and the like. Some are noted as having been written by Wilfred Bovey.

Fonds reflects Jones’ work as a scientist, but not her activities as a poet. Over two-thirds of the materials are student notes coupled with quizzes, laboratories and reports. These largely stem from her Cornell period, and cover graduate seminars in population genetics and biochemistry as well as her doctoral research in plant breeding and plant physiology. There are also notes for courses on statistics, genetics, agriculture and animal physiology from the University of the West Indies.

Materials related to Jones' research comprise laboratory notes and graphs, drafts of papers and correspondence with publishers, scientific supply companies, and other scientists in her field. Administrative papers related to research include applications to the National Research Council, budget statements, requisitions and invoices for equipment, records of laboratory assistants and summer students, and correspondence on travel arrangements.

Her teaching of genetics and zoology is illustrated by her class and seminar notes, laboratory outlines, reading lists, and examinations. The administrative side is represented by memoranda on course changes and course evaluations, correspondence on the rental of films and the purchase of equipment, files on freshman counseling and the supervision of graduate students and letters of recommendation for students. Supplementing this are minutes of faculty meetings and materials relating to the McGill Association of University Teachers.

Biographical material on Jones may be found in a file containing curricula vitae, obituaries, and correspondence concerning the Barbara Jones Fund.

These papers almost exclusively consist of records of his research and publications. His publications files contain drafts of various scientific papers, largely on secretions, correspondence regarding the reception of Die Aussere Sekretion der Verdauungsdrusen (1928) and negotiations surronding the publication of the Pavlov biography, and a biographical file containing a curriculum vitae, bibliography, and correspondence concerning appointments, honorary degrees, (1923-1948). Research materials comprise six volumes of reports on laboratory experiments and a file of daily laboratory reports (1923-1943). Babkin's professional correspondence with scholars and scientific associations covers the years 1928 to 1943. Most of the letters, incoming and drafts of outoing, concern research problems, consultation on draft articles by colleagues, and Babkin's own publications. There are also negotiations for speaking engagements, and a scattering of items on Babkin's social involvements, e.g. relief for Russian refugees, and letters from students.

The collection documents the life of Katsuji Nakashima since his arrival in Canada in 1909. The material consists of a personal handwritten journal written on rice paper in ancient Japanese; a Dominion of Canada certificate of Naturalization issued in 1919; a passport issued by the Imperial Japanese Government (1921); invitations, bills and other ephemeral items (ca. 1910-1945); military photographs; an Internment Camp Ration Book; and other personal documents reflecting the civilian and military activities of Katsuji Nakashima. The collection also contains personal belongings such as Buddhist prayer items.

Fonds consists of papers pertaining to Gillett’s publications (with the exception of We Walked Very Warily), her addresses, the editing of the McGill Journal of Education and the functions of the Faculty of Education. Materials related to her publications include notes, drafts, galley and page proofs for A History of Education, Foundation Studies in Education, Educational Technology, The Laurel and the Poppy, and A Fair Shake: Autobiographical Essays by McGill Women (edited by Dr. Gillett and Kay Sibbold). There are also some photocopies, correspondence, and copies of photographs collected for We Walked Very Warily. Her editorship of the McGill Journal of Education is documented by copies of minutes of the Editorial Board (1966-1976), correspondence on funding (1970- 1971) and with contributors (1967-1971), and files of correspondence, manuscripts and proofs for issues from 1971, 1973 and 1974. A file of addresses together with some reviews, largely on the women's movement (1975-1976), her convocation address in 1971, and her Report on Women in the Montréal Area delivered at the National Conference on Women in the University, 1973 are also included. Finally, papers relating to her work at the Faculty of Education include correspondence, public relations and summer school materials (1963-1967), agendas, submissions and reports to the Senate of the faculty's Planning Commission (1972-1973) and files of the McGill Committee for Teaching and Research on Women, 1976.

The bulk of the Hunt papers consists of scientific correspondence, with a fairly large component of notes on scientific subjects. Most of the material dates from after Hunt's departure for the United States. With the exception of a letter of appointment to the Geological Survey of Vermont in 1845, all Hunt's correspondence (incoming, with copies of some outgoing) dates from the period 1863-1891, with the majority of items from the 1880s. There are a few letters of a social or personal nature, but most concern scientific matters: geological and chemical research problems, exchange of specimens, Hunt's theories and the controversies they stirred, his publications, negotiations for patents on some of his discoveries, the business of various scientific societies, and in particular the organization of the Geological Congress. Amongst his correspondents were James D. Dana (with whom he engaged in a heated quarrel over scientific theory), James Hall, Persifor Frazer, J.W. Dawson, and various members of the Geological Survey of Canada, such as G.M. Dawson, Robert Bell, Henry Y. Hind, and George Iles. Hunt's scientific notes mostly deal with special topics in chemistry, geology, mineralogy, railways, coal products and the controversy with Dana. There are also reading notes for geological texts, lecture notes for courses in geology, 1876, and chemistry, and indexes, apparently for Hunt's books. A manuscript on "Benjamin Franklin's Autobiography: an episode in its history", notes for a lecture on "People I have met", and sketches of family history represent Hunt's wider interests. There are also clippings of reviews of books and lectures by Hunt, biographical notices, reports on scientific themes and institutions, and news of the Geological Survey.

The fonds consists primarily of Logan's scientific work. A small percentage relates to the affairs of his family and to memorials to Logan after his death. The great majority of the papers consists of scientific correspondence from about 1820 to 1874, but mostly for the years following his appointment to the Survey in 1842. The letters deal with the collection, exchange and description of geological specimens, expeditions under the aegis of the survey, problems of research and scientific interpretation, scientific meetings, and visits by scientists. The number of correspondents, both individuals and learned societies, is very large, but the most substantial bodies of letters are from J.W. Dawson, geologist and Principal of McGill University, James Hall, paleontologist of the New York Geological Survey, Alexander Murray, Logan's chief assistant, and James Lowe of Grenville, Québec, who supplied Logan with specimens and appears to have been casually employed by him on surveying jobs and field trips. Other correspondents include Sanford Fleming, E.D. Ashe of the Québec Observatory, Thomas Sterry Hunt, and R.I. Murchison of the Geographical Society of Great Britain. Some letters pertain to political or social affairs, but usually in close connection with the scientific work of Logan or the Survey. These files contain copies of some of Logan's outgoing letters, as well as some letters addressed to other individuals, generally his assistants. Other scientific papers consist of field trip records (a journal kept during an expedition in 1845, a weather table kept on Lake Superior in the winter of 1846-1847, work records and astronomical readings for surveying projects, notes on mineral deposits, and lists of specimens), manuscripts of three scientific papers, as well as "Observations on the proposed Geological Survey", and manuscript and printed maps and geological schemata, including some by Logan of the Bay of Fundy, Labrador, and Hamilton, Ontario regions. Manuscript catalogues of specimens were prepared by Logan for the Paris Exhibitions of 1855 and 1867. Official reports include Logan's annual reports for 1842-1844, an overview of the work of the Geological Survey, 1866, two reports by Logan on prospects for mining on the north shore of Lake Superior, 1846, 1847, and one on mineral deposits around Rivière-du-Loup, 1853, as well as Logan's copy of his proposed Geological Survey Bill, 1844, and some copies of reports on mining and cartography prepared by others. Logan's financial records include expense accounts for Geological Survey expeditions, as well as other professional expenditures, such as books. His private and family life is reflected by a very brief diary of an Atlantic crossing in 1856, letters to and from his brothers James and Henry, his father, his uncle Hart Logan, and Hart Logan's partner John Fleming, covering the years 1772-1856. There are also baptismal and burial certificates, and legal documents, particularly bills of sale pertaining to James Logan's farm. Memorials to Logan after his death include J.W. Dawson's correspondence concerning the Logan Memorial Fund and Collection, 1881, and a manuscript biography by Alexander Murray. There is a chronological and author/recipient index to these papers.

Additional materials received from McGill Library's Rare Books and Special Collections consist of correspondence, 1837-1871; notices of admission to scientific and historical societies, 1842-1867; a history of the geological survey 1850; a report on mining locations addressed to B. Papineau, 1847; and correspondence with Robert Bell, 1861-1874.
