The bulk of Girdwood's papers concern his work in forensic medicine. Other materials cover his research in photography, and his general medical and scientific interests. Girdwood's career as medical-legal consultant is documented by 24 cm of his notes and reports, together with some correspondence, on four poisoning trials: People vs Emma Davis (Malone, N.Y., 1881), Queen vs Provencher and Boisclair (Sorel, 1867), Queen vs Joseph Ruel (St. Hyacinthe, 1868), and Queen vs David Prevost and Damase Brunet (L'Orignal, 1881). There are also coroner's autopsy reports and notes for four cases; Girdwood's memoires of ten cases on which he served as consultant; Rogers and Girdwood's submission to the Home Office, London, on the strychnine test, together with letters to Lancet and the Times on the same subject; and notes on the counterfeiting of stamps (1893). His interest in medical photography is reflected in lists of X-rays taken by him (1898-1899) and reprints of three articles. His general scientific and medical activities are represented by a scrapbook of newsclippings on cholera (1854), a lecture on gold presented to the Natural History Society of Montréal (n.d.), essays on strychnine (1864) and water filtration (1869), a review of a textbook in physiology (1864) and some reprints, including convocation addresses to the Medical Faculty. Finally, there is a manuscript copy of an address to the graduating class of Applied Science in 1881 and a small scrapbook of printed articles by Girdwood's father, G.F. Girdwood, M.D.

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.

This collection consists of materials dated from approximately 1850-1981, but predominantly from 1913-1940, relating to Dr. Casey Albert Wood’s research, writing, correspondence, and personal interest concerning ornithology, vertebrate zoology, memoir and family history, Emma Shearer Wood and Blacker Library collection development, ophthalmology, politics, and current events.
