The fonds consists of Dr. Bensley's research notes and correspondence, particularly in relation to his publication McGill Medical Luminaries.

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.

Series D contains correspondence concerning topics of Dr. Elliott’s professional interest.
This series is divided into two (2) sub-series:
D/1) Correspondence, 1944-1986
D/2) General correspondence, 1936-1985

The fonds contains chiefly of family correspondence between members of the Penfield and Chester families, as well as clippings and correspondence regarding Wilder Penfield's autobiography "No Man Alone" and correspondence regarding posthumous honours for Wilder Penfield. Family correspondence includes a 1917 letter from Helen Kermott (later Helen Kermott Penfield) accepting Wilder Penfield's marriage proposal. Much of the family correspondence is between Wilder and Helen Penfield and their daughter Priscilla and her husband William M. (Bill) Chester Jr., as well as Bill Chester's parents William (Sr.) and Alice Chester. There are incoming letters and many carbon copies of outgoing letters. A series of 1949 letters congratulates the young couple (Bill Chester and Priscilla Penfield) on their engagement. One letter is also between Wilder Penfield and George Chester. A few materials are related to posthumous honours for Wilder Penfield, such as the naming of a building after him at John Abbott College (letter to Wilder Penfield Jr.) and a 1982 speech given by Priscilla at the Penfield Children's Center (typescript copy). There is also correspondence between Bill Chester and William Feindel. One 1976 carbon copy of a letter (1976) details the period following the death of Priscilla's father, Wilder Penfield, while the couple was in Japan. Materials related to "No Man Alone" include clippings from journals and newspapers of reviews and book announcements, as well as two copies of the book jacket and some related correspondence.

The fonds documents mainly Babkin's professional interests in physiology, especially glandular secretions and the nervous system. The fonds contains correspondence; lecture notes; citations; research notes and papers, including manuscripts sent to him by his colleagues; reprints of scientific articles mainly in Russian; and material used in the preparation of the biography of Ivan Pavlov. The latter contains correspondence with Ivan Petrovich Pavlov and members of his family, 1923-1948; photographs and portraits; and an unabridged typescript copy of Parts 1-3 of Pavlov: a Biography, with manuscript corrections, 1943-1946.
