Stansfield's student notebooks comprise three volumes of the geology lectures of Dr. Marr (1904). Research notes include laboratory records and a draft article on dolomite, and scattered notes on palaeontology and stratigraphy. His work as a teacher is documented by lecture notes on economic geography for a course given to McGill commerce students (1911).

The collection consists of informational files on Juda Hirsch Quastel, collected by T. L. Sourkes and F. C. MacIntosh for a biography of J. H. Quastel for "Memoirs of the Royal Society of London", vol. 36, 1990. The files include material from the Royal Society itself, letters from many people about Quastel, laudatory articles about him along with obituaries about his death, some notes by Hank in his handwriting, and other items.

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.

King's private papers comprise a diary for 1902, reading notes and reviews of Maria Chapdelaine (1919-1921), his pension papers, and an inventory of periodicals in his library. There are also two formal photographs and a number of snapshots of school groups, Cambridge scenes, and laboratory equipment.

Fonds documents Denstedt's research work and professional activities; a much smaller percentage is devoted to his teaching work and personal interests.

The research materials comprise notebooks, reports, and general files. Approximately 40 notebooks record experiments, mostly on blood preservation, but also on basal metabolism, lipids, proteins, serum, and urine and fecal analysis (ca 1936-1947). An additional 40 general notebooks cover not only the aforementioned topics, but also more general questions such as organic chemistry, amino acids, steroids, carcinogens, and nutrition. There is also a binder of historical background material on blood preservation. The results of this research are distilled in approximately 90 progress, interim, and final reports (1943-1963) on blood preservation, anemia, haemmorhage, agglutination, vascular fragility, and hemophilia, as well as the effects of silica, insecticides and cortisone on tissues. These are supplemented by copies of other researchers' reports on these topics (1952-1956), and by 26 reports of various committees and sub-committees of the United States National Research Council on blood and related problems, and on shock (1949-1963). A group of 50 research files contains typescripts, reports and reprints on subjects of research interest to Denstedt, particularly blood (1940-1965) and the financial side of the operations of his laboratory are illustrated by two cashbooks (1963-1966). The wider context of Denstedt's professional life is revealed by general files, approximately 300 in number, containing correspondence with colleagues, scientific and medical associations, learned journals, and granting agencies, work reports from assistants and students, and reports and clippings on subjects of special research interest, as well as on wider social and scientific issues, e.g. pollution, chemical warfare, public health and food supply. A special series of files documents Denstedt's activities for the International Society of Endocrinology (1965-1971), particularly during their third international conference (1968). There are a large number of reprints, printed reports and laboratory equipment manuals.

Denstedt's role as a university teacher is reflected in a few files of correspondence from the general series noted above with university and faculty officers, and with the McGill Association of University Teachers (1955-1971), and by some reports of Senate Committees. There is also a file of Denstedt's letters of recommendation for appointments or changes of status (1960-1965). Instructional materials include basic notes (ca 1950) for Denstedt's course in endocrinology, and approximately 2,000 slides. A few papers and theses by students are also included in this series.

Personal papers comprise lecture notes for courses on physical and biological chemistry dating from Denstedt's years as a graduate student at McGill, and a large collection of printed materials on the history of McGill, and McGill scientists, probably assembled in connection with his book, A History of Biochemistry at McGill.

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.

The bulk of the Hunt papers consists of scientific correspondence, with a fairly large component of notes on scientific subjects. Most of the material dates from after Hunt's departure for the United States. With the exception of a letter of appointment to the Geological Survey of Vermont in 1845, all Hunt's correspondence (incoming, with copies of some outgoing) dates from the period 1863-1891, with the majority of items from the 1880s. There are a few letters of a social or personal nature, but most concern scientific matters: geological and chemical research problems, exchange of specimens, Hunt's theories and the controversies they stirred, his publications, negotiations for patents on some of his discoveries, the business of various scientific societies, and in particular the organization of the Geological Congress. Amongst his correspondents were James D. Dana (with whom he engaged in a heated quarrel over scientific theory), James Hall, Persifor Frazer, J.W. Dawson, and various members of the Geological Survey of Canada, such as G.M. Dawson, Robert Bell, Henry Y. Hind, and George Iles. Hunt's scientific notes mostly deal with special topics in chemistry, geology, mineralogy, railways, coal products and the controversy with Dana. There are also reading notes for geological texts, lecture notes for courses in geology, 1876, and chemistry, and indexes, apparently for Hunt's books. A manuscript on "Benjamin Franklin's Autobiography: an episode in its history", notes for a lecture on "People I have met", and sketches of family history represent Hunt's wider interests. There are also clippings of reviews of books and lectures by Hunt, biographical notices, reports on scientific themes and institutions, and news of the Geological Survey.

The William Feindel fonds documents the research, writing, teaching, and various professional activities of William Feindel. Materials related to Feindel’s research make up the bulk of the fonds and cover his many research interests in the field of neurology as well as his interest in the history of medicine and the legacies of Wilder Penfield, William Osler, and 17th-century physician and neuroanatomist Thomas Willis. An entire series is dedicated to records related to Feindel’s role as the curator for the Wilder Penfield archives. The William Feindel fonds also documents his work for the Montreal Neurological Institute, his role as Acadia University’s Chancellor, and several professional appointments. A series of notebooks consists of Feindel’s notes on various research topics but also contains notes regarding personal matters. Along with the notebooks, a series that documents Feindel’s personal life includes materials related to his family, his years as a student, and a variety of souvenirs and books that he kept as part of his personal library.

Lochhead's papers comprise 20 pages of notes on the relationship of ferns and bryophytes, and a volume of notes of Sir William Dawson's lectures in ordinary and honours geology courses.
