Fonds contains William Wood Squire's manuscript of his thesis "Pathology and Treatment of some forms of Partial Paralysis" which won a prize as best thesis in medicine at McGill in 1864. The fonds includes a bound notebook and one loose illustration.

Fonds documents a portion of the literary activities of Sir Andrew Macphail with the typescript of In Flanders Fields and Other Poems by Lieut.-Col. John McCrae M.D. with the Essay in Character by Sir Andrew Macphail, originally published in 1919. The typescript is accompanied by a signed letter from Macphail. The fonds also contains a letter from John McCrae while on active duty in France to Carleton Noyes, Cambridge, MA, with an envelope postmarked 31 May 1916. Enclosed with the letter is an autographed signed copy of McCrae's poem, In Flanders Fields.

Fonds contains a manuscript, entitled "Remarks on the Osteology of Alexander Monro by himself", written by Dr. John George Bethune who transcribed an old damaged manuscript found in a trunk in the garret of the steam factory of Bethune's father in August 1848. The damaged manuscript was, according to Bethune, from one of three famous physicians, three successive generations of an Edinburgh family, who all bore the name Alexander Monro.

Fonds contains the manuscript of Dr. William Rees on the treatment of malaria, a lecture given before the Natural History Society of Montreal in the 1860s

Fonds shows Herbert Frederick Moseley's relations with his editor for his book "Shoulder Lesions". It contains an original manuscript with the publisher's annotations for the 1945 edition and another complete copy.

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 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.

Gould's papers fall into two series. Family correspondence covers the years 1856 to 1860, when Joseph and his brother Charles were travelling in Europe, and consists of letters home from both young men, and their parents' replies. Manuscript music comprises two volumes of church anthems, with some organ music; some are original compositions by Gould and Samuel Warren. Related to this is Gould's brief manuscript account of the origin of the Mendelssohn Choir. Some family photographs are also included.

The fonds consists primarily of Logan's scientific work. A small percentage relates to the affairs of his family and to memorials to Logan after his death. The great majority of the papers consists of scientific correspondence from about 1820 to 1874, but mostly for the years following his appointment to the Survey in 1842. The letters deal with the collection, exchange and description of geological specimens, expeditions under the aegis of the survey, problems of research and scientific interpretation, scientific meetings, and visits by scientists. The number of correspondents, both individuals and learned societies, is very large, but the most substantial bodies of letters are from J.W. Dawson, geologist and Principal of McGill University, James Hall, paleontologist of the New York Geological Survey, Alexander Murray, Logan's chief assistant, and James Lowe of Grenville, Québec, who supplied Logan with specimens and appears to have been casually employed by him on surveying jobs and field trips. Other correspondents include Sanford Fleming, E.D. Ashe of the Québec Observatory, Thomas Sterry Hunt, and R.I. Murchison of the Geographical Society of Great Britain. Some letters pertain to political or social affairs, but usually in close connection with the scientific work of Logan or the Survey. These files contain copies of some of Logan's outgoing letters, as well as some letters addressed to other individuals, generally his assistants. Other scientific papers consist of field trip records (a journal kept during an expedition in 1845, a weather table kept on Lake Superior in the winter of 1846-1847, work records and astronomical readings for surveying projects, notes on mineral deposits, and lists of specimens), manuscripts of three scientific papers, as well as "Observations on the proposed Geological Survey", and manuscript and printed maps and geological schemata, including some by Logan of the Bay of Fundy, Labrador, and Hamilton, Ontario regions. Manuscript catalogues of specimens were prepared by Logan for the Paris Exhibitions of 1855 and 1867. Official reports include Logan's annual reports for 1842-1844, an overview of the work of the Geological Survey, 1866, two reports by Logan on prospects for mining on the north shore of Lake Superior, 1846, 1847, and one on mineral deposits around Rivière-du-Loup, 1853, as well as Logan's copy of his proposed Geological Survey Bill, 1844, and some copies of reports on mining and cartography prepared by others. Logan's financial records include expense accounts for Geological Survey expeditions, as well as other professional expenditures, such as books. His private and family life is reflected by a very brief diary of an Atlantic crossing in 1856, letters to and from his brothers James and Henry, his father, his uncle Hart Logan, and Hart Logan's partner John Fleming, covering the years 1772-1856. There are also baptismal and burial certificates, and legal documents, particularly bills of sale pertaining to James Logan's farm. Memorials to Logan after his death include J.W. Dawson's correspondence concerning the Logan Memorial Fund and Collection, 1881, and a manuscript biography by Alexander Murray. There is a chronological and author/recipient index to these papers.

Additional materials received from McGill Library's Rare Books and Special Collections consist of correspondence, 1837-1871; notices of admission to scientific and historical societies, 1842-1867; a history of the geological survey 1850; a report on mining locations addressed to B. Papineau, 1847; and correspondence with Robert Bell, 1861-1874.

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.
