Fonds consists of printed materials, architectural drawings, and photographs that are overwhelmingly concerned with Hibbert’s research activities and related areas of patents and consulting. His general correspondence files (1910-1945) are almost entirely devoted to research communications and the business of the Pulp and Paper Research Institute. There are a few files of correspondence with individuals on special topics, e.g. with Benno Borzykowski on the establishment of chemical industries in Peru (1940-1943), with the Nobel Institute on Hibbert's nomination of Colin Fink for the chemistry prize (1934-1935), as well as letters concerning German refugee scientists (1933). Hibbert's research subject files (1915-1943) contain notes, drafts of articles, printed materials and some correspondence on a large range of organic chemistry topics: wood cellulose, lignin, synthetic fibers, analysis and catalysis, and explosives. Closely related to these are papers on the administration and equipment of the Pulp and Paper Research Institute (1927-1942) and other bodies.

Hibbert's files on patents (1914-1941) contain some documentation on his own patents, but largely concern patents of interest to him in the area of solvents, synthetic fibers and vanilla, pharmaceuticals, and alcohol. His work as a consultant is illustrated by files of notes, reports and correspondence on Komppa's synthetic camphor (1919), the establishment of chemical companies producing synthetic fibers, pulp and paper products, machinery, etc.

Hibbert's teaching activities are documented by two files of lecture notes (1945) and two of correspondence with the Chemistry Department (1934-1943) and the Graduate Faculty (1934-1945) on student-related topics, theses and honorary degrees.

His involvement with the American Chemical Society is revealed by general correspondence, largely concerning meetings and papers, correspondence with the Division of Cellulose Chemistry on research problems, division reports, publications, and relations with industry, and finally by communications with the Society's Journal regarding the refereeing of papers (1920-1944). Personal and biographical materials comprise a scattering of papers about his marriage (1917), academic appointments (1922-1924), library (1926-1941), retirement (1943), hobbies, clubs and interests. There is also a small body of correspondence with his friends, wife and family (1928-1945), as well as communications with his broker about stock investments (continued by Mrs. Hibbert until 1961). Bibliographies and photographs are also included. Obituary material is supplemented by letters of condolence to Mrs. Hibbert, and by a file documenting a dispute concerning Hibbert's biography in the National Cyclopedia of American Biography.

Records of his teaching career at McGill include notes for lectures, a register of student marks (Restricted), formal examination papers, course outlines and copies of class notes from 1925 to 1954. Adair's family life is documented by a collection of photographs and glass negatives, largely of Adair himself as a child and young man, with family and school friends.

There are three letters from Lord Selkirk, one from Lord Dalhousie, and eight from Lady Selkirk. The early letters concern the Red River Settlement and the North West Company. The letter from Lord Dalhousie, 1824, concerns legal matters, and the two late letters, 1828 and 1833, from Lady Selkirk are personal in nature.

Abbott's papers reflect her family background, education and private life, as well as her research and publications on medical history. There are no materials relating to her work as a pathologist. Abbott's family background is documented by a printed history (1931) of St. Matthew's, Grenville, of which Joseph Abbott was the first rector, and glass negative views of the family home in St. Andrew's. Records of her education comprise notebooks (1886-1890) for courses at McGill in classics, philosophy, English literature, and science, her graduation photograph, and a photocopy of her address as Donalda Valedictorian in 1890. Private records include diaries (1930-1940), a commonplace-book (1929-1938), and a bundle of notes, clippings, poems, letters and invitations. Three versions of her autobiography survive: the finished "Autobiographical sketch" of 1928 (photocopy), part of an undated autobiography, and a brief autobiographical note. Records of Abbott's historical research and publications include extensive notes on the history of medicine in Québec as well as papers relating to the publication of her History. Other files contain notes on the admission of women to McGill and other universities, the establishment of the Medical Museum, the amalgamation of the medical faculties of Bishop's and McGill with some administrative records of the medical faculty. Dr. Abbott's professional correspondence is represented only by a file on the Federation of Canadian Medical Women, 1938.

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).

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,

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.
