The Aileen Ross fonds consists mainly of correspondence (1935-1990), research files, a brief autobiography (1940-1980), biographical material (1920-1990), and specific talks (1942-1973). Included are personal diaries (1918-1962), appointment books (1946-1992), and Matthew Ibbotson's correspondence to Ross (1921-1927). Books, original and printed articles, newspaper clippings, and reviews of books and articles are also part of the collection. Non textual records consist of several photographs.

The fonds contains chiefly the writings of Jeremy Walker on a variety of issues in moral philosophy and related literary topics. These writings, including anthologies, drafts of books and lecture notes, demonstrate the range of his eclectic interests from his formal studies of Kierkegaard and moral philosophy to his more personal intellectual pursuits concerning the literature of Kipling, Jane Austen, and Dostoyevsky, as well as the poetry of Woodsworth and reflections on Englishness. There are also examples of his published and unpublished poetry.

His more personal writings are in diaries that cover more than 20 years of his adult life and in contrast to his erudite writings on grand philosophical topics reflect his feelings and at times his dreams, on the state of his health, relationships with women, and recount the day-to-day events of urban travel and socializing.

His personal and family relationships are reflected by correspondence with family, friends and students, photo albums of travels to England and Greece, travel diaries document his summer activities from 1947 -1950, including lists of books read, drawings and photographs. As well, in a file titled Personalia (3) Apologiai Walker provides some personal chronologies, and reflects upon his writings and his life.

The fonds consists mainly of documents relating to Gales' private life, including correspondence with family and friends during the war years (1931-1946) and correspondence documenting his social networking amongst graduates (1978-1985).

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)
