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.

Fonds reflects L.-G. Papineau's daily work as an engineer between the years 1901 and 1905. Each volume is a daily diary, covering a year. Daily entries describe the activities of the people in his office. Most entries are technical: daily follow-ups on public works projects, including in the Montreal and Sorel harbours, Hochelaga, and on the Saint-Pierre River, meetings, finished tasks, and the absence of workers. Some are family related or comments on the news (for example, Queen Victoria's funeral on February 4th. 1901). Weather conditions and water levels are reported regularly, as it influences the pace of work on the construction sites.

Madame Desrivière's diaries describe social, family and economic life in Montréal and Stansbridge, Québec. The first (1843-1846) and last (1853-1854) volumes are in French, the others in English.

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 two diaries for 1917 and 1918, and one address book of Dr. Robert Arthur Bowie during World War I. It includes 29 diaries written by his wife Pearl Blanche Bowie and by his daughter Margaret E. Bowie, from 1916 to 1951. In addition, there are a large number of photographs and negatives.

The D'Aigle papers fall into three series: diaries, correspondence and a scrapbook of photographs and memorabilia. The diaries (1912-1914, 1927, 1935-1952) are largely devoted to a day-by-day account of prospecting journeys.
