Fonds consists of correspondence and literary manuscripts, documenting all aspects of MacMillan’s career. Biographical background is provided by his own notes on his life and family history. From his student years come certificates and testimonials in support of his application for a Rhodes Scholarship (1904-1909). His war experience is recorded in letters from the front preserved by his family, and by a personal diary for 1917. There are also approximately twenty photographs of Macmillan and his family taken between about 1905 and 1940.

Macmillan's correspondence includes files of letters to his wife (1917-1936) on his war service and political affairs; personal and social letters (1923-1929); political correspondence, including several letters from McKenzie King (1926-1946); letters concerning McGill, including a number from Sir Arthur Currie and from Stephen Leacock (1920-1947); post-retirement correspondence on McGill and public affairs; and correspondence concerning his publications (1920-1960). There are also files of invitations to events at McGill and elsewhere.

The manuscripts fall into two categories: political speeches and literary manuscripts. Besides notes and texts for his own speeches, there are also texts of, and newspaper clippings about speeches written by Macmillan for Sir Arthur Currie and others (1920-1950). Drafts and typescripts of his literary works are supplemented by notes, clippings and correspondence.

Most of this material concerns the last illness and death of Robert Harvey Warden, and comprises letters of sympathy to himself and his wife, and following his death, condolences to his wife and children. The letters are from personal friends as well as from Presbyterian bodies. Printed obituaries are also included. Letters of condolence to Mrs Warden on the death of her daughter Lila Dunton are likewise accompanied by newspaper obituaries, 1908.

A small number of letters between Graham and E.B. Tiffany, an offical of Henry Birks and Co., discuss the occurrance of diamonds in Canada (1949). A record of Graham's work as a teacher in his field is a set of notes on the use of the petrographic microscope.

The fonds contains materials that Dr. M. Entin collected for his biography of Dr. Archibald. Mainly include articles relate to tuberculosis, pancreatitis, wound healing, history of surgery, and scientific writing. It also includes letters from Edward Archibald to Mrs. Archibald, letters to Archibald from William Osler and Sir Henry Gray, addenda of Archibald's world journey in 1936, and articles by Archibald.

Some draft chapters of the biography of Dr. Archibald and research data for 100th Anniversary of Royal Victoria Hospital can also be found in the fonds.

Fonds consists of records (originals, printed materials, photographs and motion pictures) that are almost entirely of a professional and research nature, covering Barnes’ general scientific and university work during World War I, a number of special research problems, and his involvement in scientific and social organizations.

His general scientific and university files (1914-1915) contain correspondence, including copies of some of Barnes' outgoing letters on departmental adminstration, Barnes' lectures, publications, scientific apparatus, research problems and the exchange of information. Correspondents include colleagues in other institutions (including Ernest Rutherford), learned societies, and private industry. This series also contains a file on purchases for the University Library, and inventories of Barnes' library.

Far more extensive are the materials on special research problems. These comprise notes, essays and correspondence on the detection of submarines (1915-1917) and on the development of anti-freezing devices for fire extinguisher and sprinkler systems (1917). A report by Barnes on the effect of ice conditions on St. Lawrence navigaton is supplemented by printed background materials and copies, or extracts from other reports. Barnes' work on icebergs is documented by five binders of clippings, photographs, maps and diary notes on research expeditions to Newfoundland (1924-1929). Practical experiments in ice clearance are illustrated by bound notebooks of clippings and photographs, as well as a number of loose photographs showing ice and flooding damage, use of thermite and calcium chloride, apparatus and ice-crushers (ca 1921- 1929). Finally, two reels of 35 mm motion picture film (ca 1930) show Barnes experimenting with a new mercury microthermometer.

Barnes' work as Hon. Secretary of the Canadian Committee of the British Science Guild is documented by correspondence from 1907 to 1919, largely concerning the recruitment of members and officers, but also touching on a survey of science teaching in schools and the Panama-Pacific Exposition of 1917. Less extensive files cover Barnes' involvement in the International Council for the Exploration of the Sea (1912-1914), the Rotary Club (1917) and the McGill Graduates' Society (1919)

The fonds documents Dorothy Duncan’s personal and professional activities as an American-born Canadian writer and painter, primarily between 1930 and her death in 1957. Duncan’s career as a writer is represented by scrapbooks, clippings, and photographs related to her published works, two unpublished manuscripts, and contracts and correspondence with publishers and her literary agent in New York. Her activities as a painter are documented in clippings, lists of paintings, and contracts with art galleries. The fonds also contains personal correspondence, including letters from friends, family, fans, and a significant number of letters from her husband, Hugh MacLennan. Duncan’s notebooks and diaries also attest to her personal and professional activities. They document her early adulthood in Illinois and her later life in Montreal, and include notes, agendas, and a ledger. The fonds also contains two albums of personal photographs.

Wallis' papers are grouped into three series: general scrapbooks, military scrapbooks, and military diaries. General scrapbooks, covering the years 1908-1977, contain letters, photographs, and printed materials relative to Wallis' career. Some volumes include his diary for the period, and all are heavily annotated. They cover all aspects of his career from high school to post-retirement, with special emphasis on his military career and social life. Military scrapbooks contain the same variety of materials for the period 1911-1969, but are devoted exclusively to Wallis' activities during the two World Wars, and his roles in the Black Watch and as an Honorary A.D.C. Military journals give brief reports of his daily activities form 1941 to 1945.

Fonds consists of general professional correspondence, 1913-1961, including Maass’ outgoing letters for 1946-1954. Topics covered include defence research, the Pulp and Paper Institute, N.R.C. appointments, visits of scientists, and political questions (e.g. letters to and from Lester Pearson on NATO and the nuclear deterrant). There are also letters of recommendation by Maass, and personal communications from colleagues. A special binder of congratulatory letters marks his election to the Royal Society (1940), and there are similar files on his retirement (1955), and of condolences to his widow at his death (1961). Maass also assembled photostat copies of letters by eminent 19th century British scientists addressed to his great uncle, Prof. Plucker of Bonn.

Studies and research are documented by a physics laboratory notebook (1908-1909), and a "summary of data on hydrogen peroxide" collected in collaboration with W. Hatcher (1918-1919). A few addresses on the Canadian Institute of Chemistry (1939), the Pulp and Paper Research Institute (1945), and the relation between the Defence Research Board and the universities are included.

Fonds consists mainly of Perrin's typescript lectures (1922-approximately 1929). Some of the lectures are in series, and were probably used in teaching university courses. Some consist of introductory or graduation addresses to music students. Predominant topics include music education, music in Canada, national musical styles, formal and genre developments, aesthetics, and the work of individual composers. Perrin's correspondence comprises a general file (1912-1949) concerning faculty matters, concerts, publications, and personal affairs, a file regarding concert and speaking engagements (1911-1929), and a few letters about the publication of Perrin's Canadian Song Book (1918). Some essays and answers to examination questions stem from Perrin's student years.
