The minutes series comprises eight bound volumes, two publications and one envelope of loose duplicate minutes. The minutes document proceedings from the annual, general, monthly, special, ordinary and extraordinary meetings held by the Society. It consists of the minutes from the Natural History Society (1827-1923), the Natural History Society Council (1827-1922), and the Natural History Society Committees (1906-1908).

The handwritten and typed minutes document the Society’s activities, including lists of members, newspaper articles, donations to the Society, elections, advertisements for sponsored lectures, and reports from committees. Handwritten copies of letters from Dr. Meade, Mr. C.U. Shepard, Major Delafield (File 5.2) and Robert Burn (File 9.1) to the Society as well as letters sent on behalf of the Society (Smithsonian Institute, File 5.1) are included with the minutes.

This series consists of falconry equipment, falconry exhibit labels and cards, a taxidermy young peregrine falcon, and two large burlap envelopes collected by Casey A. Wood from 1920-1937. Also included in this series are two Wolf Envelope Co. (Ohio) allsteel transfer cases manufactured by General Fireproofing Co., Ohio for book binding, found within Wood’s materials (191-?).
The leather falconry equipment and those worn by the young peregrine falcon were made by Otto Kals in Dusseldor-Benrath, Germany approximately in 1930-1937 and the falcon bells were made by Captain Russell Luff Meredith in the United States in 1920. The taxidermy young peregrine falcon in training is mounted on a weathering block and wears a United States Bureau of Biological Survey identification band, indicating that it was acquired legally. The falcon is also wearing a hood, a leash, a swivel, and a jess. A falcon bell is also held with the falcon as well as another leather jess, which is damaged.
Many of the artefacts in this series were purchased by Casey A. Wood due to his interest in falconry during his research with Marjorie Fyfe for the publication “The Art of Falconry,” a translation of Frederick II of Hosenstaufen's “de Arte Vendandi cum Avibus.” The falconry items were gifted to the Redpath Library at McGill University in autumn 1938 by Dr. Casey A. Wood.
The two large burlap envelopes previously held the contents of flat box MSG 1203-2-25, which contains photostats produced by the British Museum of Emperor Frederick II's manuscript “de Arte Venandi cum Avibus,” books I-II. It is evident on one envelope that labels were removed, while the other includes two original labels indicating Persian miniatures and drawings from the "fourteenth to nineteenth century, collected in North India, Bombay, Cairo, and London by Casey A. Wood," were previously contained. These two labels were scratched out and the note "Fred. II" was added.

The series consists of research files on the etymology of Hebrew and Semitic languages.

The communications series chiefly reflects the public role of Somerville as an ethicist and researcher through a mixture of personal/professional correspondence, often with colleagues, invitations to events and greeting cards.

George Mercer Dawson's papers comprise professional, scientific and family correspondence, some scientific manuscripts, drawings and photographs of Western exploration, juvenalia, student materials, and poetry. His scientific correspondence (boxes 54-55) commences in 1872, but drops off sharply after the early 1880s. The letters, and his occasional draft replies, document the political and administrative fortunes of the Geological Survey, the North American Boundary Commission, and various learned societies. As well, they report on field research, particularly on mineral deposits, arrangements for equipment and assistants for expeditions, and the exchange of specimens. The correspondents include other members of the Survey, government officials, and business concerns, especially railways and mines. Dawson's scientific manuscripts fall into two groups: notes and reports on Western exploration, geology, mining, and Indigenous communities, 1870-1875, and 5 cm of general lectures on physical geography delivered to the Montreal Ladies' Educational Association, 1880. Closely allied to his scientific and exploratory work are an album of photographs taken in western Canada in 1894-95 (box 70), and about 10 cm of pencil sketches, sepias and watercolors of landscapes, many produced during exploratory trips in 1873-1874, and 1881 (box 59). Materials of a more personal nature include juvenalia (short essays, drawings, and two diaries from 1861 and 1865) and 16 lecture and laboratory notebooks from his student years at the Royal School of Mines, 1869-1872, together with pocket diaries, memorandum books, and notes of geological field trips during the same period (boxes 57-59). Dawson also wrote poetry, of which 10 cm of manuscript is extant (box 56), mostly reflections on states of mind, the Canadian landscape and seasons, and the vanity of human society, endeavour and love. There is also a small notebook of poems and reflections during an European trip in 1882 (box 58). Family correspondence includes 22 letters from his grandfather James Dawson, 1856-1857; 5 cm of letters from J.W. Dawson, 1856-1899; 15 cm from Margaret Mercer Dawson, 1865-1901; 3 cm from Anna Dawson Harrington, 1869-1901; 3 cm from William Bell Dawson, 1865-1899; 2 cm from Rankine Dawson, 1870-1900; and a handful of items from other members of the family.

Other papers primarily concern Dawson's geological interests, and consist of a diaries and general notebooks, 1873-1899; miscellaneous articles on geological subjects, 1887-1894; papers connected with explorations in the Yukon and with the Boundary Question between Alaska and British Territory and with sealing regulations in the Bering Sea, 1887-1897; correspondence, 1883-1898; and poems.
