The collection contains correspondence, curriculum vitae, a poem written by his wife, Elizabeth Turnor, a record of medical examinations for the Coroner's Court of Montreal, 1894 and lectures notes. The greater part of the notes consists of embryology notes made at the Anatomisches Institut, Munich, around 1900.

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 reflects Jones’ work as a scientist, but not her activities as a poet. Over two-thirds of the materials are student notes coupled with quizzes, laboratories and reports. These largely stem from her Cornell period, and cover graduate seminars in population genetics and biochemistry as well as her doctoral research in plant breeding and plant physiology. There are also notes for courses on statistics, genetics, agriculture and animal physiology from the University of the West Indies.

Materials related to Jones' research comprise laboratory notes and graphs, drafts of papers and correspondence with publishers, scientific supply companies, and other scientists in her field. Administrative papers related to research include applications to the National Research Council, budget statements, requisitions and invoices for equipment, records of laboratory assistants and summer students, and correspondence on travel arrangements.

Her teaching of genetics and zoology is illustrated by her class and seminar notes, laboratory outlines, reading lists, and examinations. The administrative side is represented by memoranda on course changes and course evaluations, correspondence on the rental of films and the purchase of equipment, files on freshman counseling and the supervision of graduate students and letters of recommendation for students. Supplementing this are minutes of faculty meetings and materials relating to the McGill Association of University Teachers.

Biographical material on Jones may be found in a file containing curricula vitae, obituaries, and correspondence concerning the Barbara Jones Fund.

Fonds documents Thomson's research, his consultations with government, and his involvement in learned societies and university associations. As well, a significant percentage of the material is of a nonprofessional and private nature, focussing on Thomson as a public speaker.

Papers devoted to research consist of 18 cm of background notes, summaries and extracts on nutrition, protein and carbohydrate metabolism, and vitamins. Approximately .6 m of card indexes contain summaries of Thomson's professional reading in the 1920s and 1930s. For the 1940s and 1950s, the papers deal mainly with consulting. They consist of correspondence and reports for the Defence Department (1942- 1946), the Canadian Council on Nutrition (1946-1955) and the Canadian Council on Dietary Standards (1950-1957). Nutrition and research in this field are also the subjects of correspondence with the Royal Society, the Medical Research Council, and the Canada Council during this period. Thomson's work as a university teacher is documented by lecture outlines and examination question papers. His administrative positions led to his involvement in the National Council of Canadian Universities. These correspondence files (1946-1949) deal with academic exchange, scholarships, travel funds and conferences.

Speaking engagements are recorded by correspondence (1953-1954) and in drafts for speeches delivered between 1950 and 1961. Only a few of these discuss scientific topics; most discuss the nature of education, the relation of science to society, and of science to literature. There are also book reviews and background files of quotations and humorous poetry. Correspondence files, which Thomson generated as the Chairman of the Nutrition Committee of the Montréal Council of Social Agencies, are also found here (1939-1944).

Financial affairs, personal purchases and charities, travel expenses, and publications (particularly his Life of the Cell) dominate the private papers (1925-1963). There are also correspondence files maintained by Thomson's secretary during his last illness.

This series consists of research, writing, and correspondence files relating to Casey Wood's major and minor publications and unpublished works, as well as, others assisting in Wood's publications, research, or writing about Wood. The majority of the research and writing materials for Wood's published and unpublished works were created between 1920-1940, while other materials collected during Wood's life, those associated with his memoir and obituary, date from approximately 1850-1943.
Some prominent writings by Wood include “Introduction to the Literature of Vertebrate Zoology” (1921-1956), his unpublished memoir (ca. 1850-1939), “Fundus Oculi” (1911-1934), Wood family history (1920-1940), “Birds of Fiji” (1920-1928), “Through Forest and Jungle in Kashmir and North India” (1921-1934); Persian, Arabic and Hindustani manuscripts (1927-1934); and “The Art of Falconry” (1942).
The series consists of many volumes and files containing a number of record types including manuscripts, typescripts, proofs, publications, photographs, correspondence, clippings, printed material, postcards, journals, administrative and financial records, and artwork. Some of the volumes are scrapbooks containing many of these materials mounted within, while others include similar materials bound within. These volumes do not necessarily have a clear organization but are sometimes arranged chronologically or by correspondent.

There are 2230 incoming and outgoing pieces of correspondence including letters, postcards, notes, telegrams, and cards. Subseries 1) Introduction to the Literature of Vertebrate Zoology includes 1313 pieces of correspondence, the largest number of correspondence within the collection.

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.

Documents concerning Pappius’s activities as a researcher, primarily the production and publication of experimental research.

The fonds contains materials that Dr. M. Entin collected for his biography of Dr. Archibald. Mainly include articles relate to tuberculosis, pancreatitis, wound healing, history of surgery, and scientific writing. It also includes letters from Edward Archibald to Mrs. Archibald, letters to Archibald from William Osler and Sir Henry Gray, addenda of Archibald's world journey in 1936, and articles by Archibald.

Some draft chapters of the biography of Dr. Archibald and research data for 100th Anniversary of Royal Victoria Hospital can also be found in the fonds.

Fonds documents J.B. Johnston's professional activities from 1839 to 1859. It also includes his medical thesis De delirio tremente, Edinburgh, 1833. The fonds contains a logbook with notes, summaries of readings, reports of unusual medical cases and obstetrical list, and his medical thesis.

Fonds shows Thomas Gibson's interest in history of medicine. It contains papers on John Palmer Litchfield and on the General Council of Medical Education and Registration of Upper Canada.
