MacIntosh's involvement with the Medical Research Council of Canada is documented by correspondence, agendas and minutes (1960-1962) concerning grant applications and administrative affairs, particularly the Advisory Committee on Policy.

Fonds contains G.E. Tremble's notes on the anatomy of the ear from lectures by Professor Ruttin at the University of Edinburgh in 1924, a letter from Dr. Wilder Penfield and a photograph of a case of 1935. The fonds includes a notebook, a letter and a photograph.

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.

A telegram to George Glassco reports that Gordon Bond Glassco has been wounded in action.

Challies' papers are related to his teaching career at McGill. They consist of two binders of lecture notes and one of case materials for his course in Civil Procedure (1946-1966), and a file of correspondence, course materials and examinations for his course in Engineering Law (1969-1971).

The bulk of Girdwood's papers concern his work in forensic medicine. Other materials cover his research in photography, and his general medical and scientific interests. Girdwood's career as medical-legal consultant is documented by 24 cm of his notes and reports, together with some correspondence, on four poisoning trials: People vs Emma Davis (Malone, N.Y., 1881), Queen vs Provencher and Boisclair (Sorel, 1867), Queen vs Joseph Ruel (St. Hyacinthe, 1868), and Queen vs David Prevost and Damase Brunet (L'Orignal, 1881). There are also coroner's autopsy reports and notes for four cases; Girdwood's memoires of ten cases on which he served as consultant; Rogers and Girdwood's submission to the Home Office, London, on the strychnine test, together with letters to Lancet and the Times on the same subject; and notes on the counterfeiting of stamps (1893). His interest in medical photography is reflected in lists of X-rays taken by him (1898-1899) and reprints of three articles. His general scientific and medical activities are represented by a scrapbook of newsclippings on cholera (1854), a lecture on gold presented to the Natural History Society of Montréal (n.d.), essays on strychnine (1864) and water filtration (1869), a review of a textbook in physiology (1864) and some reprints, including convocation addresses to the Medical Faculty. Finally, there is a manuscript copy of an address to the graduating class of Applied Science in 1881 and a small scrapbook of printed articles by Girdwood's father, G.F. Girdwood, M.D.

The fonds primarily reflects Pappius’s activities as a researcher at the Montreal Neurological Institute-Hospital (MNI/H): both her experimental research as such and various support activities, including academic publication, coordination of research projects with colleagues, and acquiring funding. It also contains much information about her leadership of the Clinical Neurochemistry Laboratory. The fonds contains smaller amounts of documentation regarding her activities as a professor at McGill University, her administrative roles at the MNI/H, and her participation in professional organizations, which reflects the smaller place that those roles occupied in her professional life.

The period of time best documented in the fonds spans the early 1980s to Pappius’s retirement in 1995. Correspondence with colleagues, mostly though not exclusively work-related, contains relatively more material from Pappius’s early career; although, here too, most of the material dates from the 1980s and after.

The main document types in the fonds related to Pappius’s research activities are experiment worksheets and printed tabular research data. Many of the research-related files contain negatives of autoradiographies, with a smaller number of photographic prints. Correspondence can be found in many series besides series F (Correspondence), as much of Pappius’s work was collaborative in nature.

The fonds is divided into eight series: (A) Research, (B) Academic events, (C) Teaching, (D) Administrative activities, (E) Professional organizations, (F) Correspondence, (G) Personal collections, and (H) Visual documents.

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.
