The Canadian Officers’ Training Corps, McGill Contingent Fonds consists of two series: historical records and administrative records. The majority of the historical records consist of scrapbooks containing mostly news clippings and personal correspondence (1914-1962). One part, covering 1914-1917, consists of news clippings on the C.O.T.C. and the 148th Battalion.A second group of historical scrapbooks and records begins in 1914 and continues through to 1939. Besides press clipping, these scrapbooks contain photographs, orders, invitations, copies of pamphlets, and other records such as the log book of the Ski Camp, 1935-1936. These scrapbooks were the model for the 8-volume Historical Record of the C.O.T.C. during World War II. These volumes contain a running chronology, orders, press extracts and clippings, statistics, photographs and personal reminiscences. The last volume is a service record of all C.O.T.C. members. These are supplemented by two news clippings scrapbooks for the period 1939-1942. A "Book of the Six Universities Companies'' of the Princess Patricia Canadian Light Infantry was prepared for the unveiling of a memorial plaque after World War II. It contains a historical record and statistics. Other historical files include printed records of the 148th Battalion, correspondence, programmes for the 1962 celebration of C.O.T.C.'s 50th anniversary, and miscellaneous Christmas cards, invitations, programmes, recruiting and activities booklets, and standing orders. The administrative records are composed mostly of minutes, with some reports and official letters (1941-1959), as well as Commissions for Lieutenants (1915-1916), directories and roll calls (1917, and 1939-1949), handbooks (1916), and orders (1914-1929). Also found in the fonds are some scattered periodicals (1915), religious texts (1914), a souvenir book (1918), speeches (1920), photographs, and stationery.

Fonds consists of contemporary manuscript copies of various legal records and instruments relating to the Capacci family. Includes one manuscript written on parchment in pale brown ink, ruled in pale brown ink, and bound in full contemporary blind tooled calf with laid paper endpapers and remnants of ties on covers, as well as a smaller booklet, written on parchment glued into a laid paper wrapper. Documents appear to be dated between 1556 and 1583 and are written in Latin and Italian (sometimes alternating within document). The legal instruments appear chiefly related to the dowry of Orietta Capacci (the dowry is also referenced in an Italian note in a later hand (1650?) inside front cover). Some names found throughout the documents include Orietta Capacci (or Orietta de Capacci) and Annibale (or Anibal) Camillo de Capacci.

The bulk of these papers are records of research. Drafts of six articles co-authored by Winkler, a number of them on RDX, an explosive, are in some cases accompanied by graphs and correspondence. A file of notes, graphs and reports of research assistants focusses on solution polymerism. There is also a report by Winkler to the Federal Department of Agriculture on bacon (1940), and two draft articles by colleague J.A. Perce. Materials from his student years are also research oriented: his M.Sc. thesis on hydration of bio-colloids, and his Oxford Ph.D. dissertation "The kinetics of gas reactions". Teaching files contain three undergraduate research projects by Winkler's students, and lecture notes for courses in thermodynamics and chemical kinetics. Winkler's writings on non-scientific topics include addresses on the nature of education and the future of the Royal Society of Canada, his obituary of Clifford Purves for the Proceedings of the Royal Society of Canada (1966), and a diary of a visit to China (1974).

Bellair's personal papers comprise scrapbooks, 1898-1939; biographical, parliamentary and miscellaneous notes, 1879-1945; and correspondence, 1889-1951.

Literary interests are revealed by notes on Sir John Fisher, 1915, and H.G. Wells, 1932-1934. Some books from Bellairs' library, with his annotations, are included in his papers.
