Adams' papers are largely concerned with his experiments on the mechanical deformation of rocks. Glass lantern slides, both for lectures and private record, are also included, as well as some materials on his interest in religion and in the history of geology. His scientific research is documented by working papers and experimental materials on rock deformation, 1896-1912. These consist of ten notebooks and one scrapbook recording his experiments, as well as notes, photographs, and carbons of typescript chapters on background literature, equipment used, and specific minerals. There are also graphs recording results, and over 1,000 photographs, glass negatives, and petrographic microscope slides. Adams' index-card bibliography lists articles and reports on Canadian geology and mining (ca 1900-1920). Adams' collection of glass slides and negatives were used for teaching geology and as a private record of his travels and family life. These slides number approximately 1,000, and show mines (particularly in Canada) volcanoes and glaciers, a large collection of views of Mexico, the Laurentians, China, the Rockies, England and Palestine, as well as family and vacation scenes. Also included are two essays, and an outline for a third on the Christian life (1937), short reflexions on his activities from 1937 to 1942, a photocopy of his will (1943), clippings of articles where he is mentioned (1919-1942), and notices of his history of Christ Church Cathedral (1941). Adams' interest in the history of geology is reflected in a manuscript biography of A.R.C. Selwyn, for the centenary of the Geological Society of Edinburgh, and a handful of letters and notes on the early use of the word "geology" (1932). His post-retirement travels resulted in a manuscript essay on mining in Malaya.

"Architectural Drawings, 1920-30, 4 drawings." The archive contains student drawings by Chambers, primarily of Italian architecture, as well as a design for a small museum submitted by Chambers in 1925 for the Tite Prize of the Royal Institute of British Architects.
"Photographs, n.d., ca. 70 photographs." Sculptures created by Chambers while he was was student at the Royal Academy and his submission for the The Prize are recorded on photographs.
"Personal Papers, n.d., 45 cm." Papers from Chambers' student years include notebooks on various subjects including German grammar, lectures on architectural aesthetics and a typescript of a murder mystery set in an artists' colony. The information about the photographs and the papers was taken from the McGill Universtity Archives guide, Vol. 2, page 15. The accession does not mention these items, nor does the file in the small collections drawer.

"Dessins architecturaux, 1920-1930, 4 dessins." Le fonds contient des dessins d'étudiant réalisés par Chambers, surtout d'architecture italienne, de même que le plan d'un petit musée proposé par Chambers en 1925 pour le Prix Tite du Royal Institute of British Architects.
"Photographies, s.d., environ 70 photos." Les photos rendent compte de sculptures réalisées par Chambers à l'époque où il était étudiant à la Royal Academy et du projet qu'il a soumis au Prix Tite.
"Documents personnels, s. d., 45 cm." Au nombre des documents qui datent des années d'études de Chambers, signalons des cahiers de notes sur divers sujets dont la grammaire allemande, des cours sur l'esthétique architecturale et le tapuscrit d'un roman policier dont l'action se situe dans une colonie artistique.

Subfonds includes designs for domestic architecture in Montreal (133 architectural drawings, 1907-1910), including alterations to existing structures, comprise the bulk of Hyde's architectural projects documented in the archive. Also included is a proposal for the Mission Church in Montreal, an addition to the Presbyterian church in Valleyfield, PQ and a design for an apartment building in Montreal. The subfonds also contains photographs of the finished exteriors of two designs for domestic architecture (1909).

L'essentiel des projets architecturaux de Hyde représentés dans le sous-fonds se rapporte à de l'architecture domestique à Montréal et notamment à des modifications apportées à des structures existantes (1907-1910, 133 dessins). Il y a également une proposition pour la Mission Church de Montréal, une annexe à l'église presbytérienne de Valleyfield (Québec) et le plan d'un immeuble à appartements de Montréal. Le sous-fonds contient 2 photos de la finition extérieure de deux projets d'architecture domestique (1909).

This series consists of glass plate negatives and other photographic materials with their original boxes relating to the Feather Book, ornithology, falconry, McGill University Library, and Casey Wood. The majority of the glass plates were produced in Berlin, Germany by Agra, while a few were produced in London, England and Toronto, Canada; which is indicated on the boxes the plates were contained in. On many of these boxes, McGill University librarian Dr. G. R. Lomer’s name appears, indicating these plates and photographic materials were used for library-related activities. Most of the plates, photographs, and photographic negatives (1927, 1930, 1956) show pages from the Feather Book by Dionisio Minaggio. Other glass plate negatives and photographic material depict artwork or images relating to ornithology and falconry, a portrait of Casey Wood (1927), Gronvold’s painting of Wood’s parrot John III (1930?), an ornithological archeological exhibit in the Redpath Library (1924), and library stacks in the Redpath Library (1924).

Collection consists of three albums containing photographs taken at Grenfell Mission and one framed photograph. Albums feature many photographs of St. Anthony and the region, its inhabitants, the medical staff at the Grenfell Mission, and activities such as dogsledding.

The fonds primarily reflects Pappius’s activities as a researcher at the Montreal Neurological Institute-Hospital (MNI/H): both her experimental research as such and various support activities, including academic publication, coordination of research projects with colleagues, and acquiring funding. It also contains much information about her leadership of the Clinical Neurochemistry Laboratory. The fonds contains smaller amounts of documentation regarding her activities as a professor at McGill University, her administrative roles at the MNI/H, and her participation in professional organizations, which reflects the smaller place that those roles occupied in her professional life.

The period of time best documented in the fonds spans the early 1980s to Pappius’s retirement in 1995. Correspondence with colleagues, mostly though not exclusively work-related, contains relatively more material from Pappius’s early career; although, here too, most of the material dates from the 1980s and after.

The main document types in the fonds related to Pappius’s research activities are experiment worksheets and printed tabular research data. Many of the research-related files contain negatives of autoradiographies, with a smaller number of photographic prints. Correspondence can be found in many series besides series F (Correspondence), as much of Pappius’s work was collaborative in nature.

The fonds is divided into eight series: (A) Research, (B) Academic events, (C) Teaching, (D) Administrative activities, (E) Professional organizations, (F) Correspondence, (G) Personal collections, and (H) Visual documents.
