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.

The fonds illustrates Dr. Cone's work as a neurosurgeon and consists of correspondence, letters, articles, newspaper clippings, obituaries, photographs, slides, research material and notes, course material, annual reports, manuscripts, typescripts, annotations, published and unpublished manuscripts written by Dr. Cone, printed copies of articles, and patient files.

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.

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.

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.

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. Dr. Gibson's notes on the translation of Theodore Turquet de Mayerne of the Opera Medica of Joseph Brown, ed. 1700. Correspondence.

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.

Fonds consists of a manuscript translation by Dr. Gruner of volume II of the Canon of Medicine of Avicenna dated 1957 and vocabulary indexes of Arabic names of Materia Medica, Latin-English names, Latin-Arabic equivalents, native names and others. These vocabularies were done in 1929-1930. It also contains three volumes of Dr. Gruner's research on cancer. This work was done through the Archibald Cancer Research Fund, from 1932 to 1946. In volume III, a printed address "A Vagabond Cruise Round Cancer" (1950) is inserted in the cover.

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.

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.
