The fonds consist of diaries, photographs, scrapbooks, photographs albums and ephemera created by or about Canadian nursing sister Clare Gass (1887-1968). A diary and a photograph album chronicle Clare Gass's experiences as a nurse with the Canadian Army Medical Corps stationed in France and England during the First World War. The diary contains entries dated between 4 March 1915 to 31 December 1916 and also features an early appearance of the poem "In Flanders Field," written by John McCrae during the war upon the burial of a close friend. It is copied out in the diary entry for 30 October, nearly six weeks before its first publication in the magazine Punch on 8 December 1915. The diary originally had ephemeral material originally laid in, including newspaper clippings, manuscript notes and letters, one photograph, pencil drawings, and ten dried plant specimens. These have been removed from the diary for preservation purposes. Her photograph album from the First World War begins in April 2015 with photos of the nursing sisters assembled for inspection before deployment and the sea crossing to Europe. The photographs include depictions of soldiers and nursing sisters, oftentimes in their huts, and hospital interiors from multiple hospitals at which she worked and visited. It contains photographs from various postings in Etaples, Camiers, Cliveden (England) Boulogne, and Rhyl (Wales), as well as landscapes, historical sites, and other scenes from the surrounding areas that she toured, including a trip to Scotland. Leaves 13 and 14 of the photograph album also contain the text of “In Flanders Field.”

Loose photographs also document Gass’s wartime experiences in France, as well the hospital at St. Anne de Bellevue, Quebec, and Gass's transit duties in the Rockies in 1919. A series of photographs are from the visit of the Prince of Wales to Quebec October and November of 1919. Other loose photographs also depict wounded veterans, as well as personal photographs, including a portrait of Clare Gass at age 13.

Her childhood is also documented in the fonds by a photograph album containing photos from her years attending Edgehill School. The photos date chiefly between 1904 and 1905 and depict school exteriors, interiors, friends and classmates, as well as school activities such as Drill Class.

An additional folder contains material compiled by Gertrude Henderson, including letters to Clare Gass, some of her writings, and other ephemera, such as clippings noting Gass’s retirement, sketches, some of Gass’s poetry and stories, a memorial from King George to those who served in the war, and manuscript notes on Gass’s school and word record, including years and places that she was stationed. The folder also contains assorted later photographs of Gass.

Fonds documents the development of Dr. Boyd's career in trauma care and emergency medical services systems, beginning at the University of Maryland in Baltimore and Cook County Hospital in Chicago, where he became interested in hemorrhagic shock and other clinical investigations, through his work in establishing national emergency medical services systems and his experience with the Indian Health Service. Also includes publications and clippings honouring Boyd's contributions as the founder of emergency medical services systems. Fonds largely comprised of reprints and copies of articles for scholarly and popular publications. Also contains some manuscripts of unpublished works and one draft of published work.

The fonds is divided into series, following the provenance and arrangement of the depositor as much as possible. Among the principal series are: President's binders or files, Secretary's binders or files, CHLA/ABSC special reports, and CHLA/ABSC publications. Within the series are found sub-series, i.e. President's binder, correspondence. The organization of the binders revolves around the Board Meetings, which occur three times a year, in June, October and February. At this time, reports are presented and decisions acted upon. Addenda to the Board Minutes frequently exceed 10 items. The fiscal year is from June 1 to May 31.

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.

The fonds contains one prescription book of Dr. Robert Todd Reynolds, with some clippings of medical drawings in the back; 3 pages of the Reynolds' family genealogy record and one page of an article "The Ancestral Roof: Domestic Architecture in Upper Canada" and a photo of the house, indicating the relationship between James McGill des Rivières and the Reynolds family; 4 of R. T. Reynolds' Diplomas, one from McGill.

Fonds consists of chiefly correspondence of or about Dr. John Clarence Webster, from 1892 to 1952. It also contains his medical thesis from 1891, "Tubo-pentoneal ectopic gestation. The anatomy of the pelvis during the puerperium, and the female pelvic floor,"with accompanying 2 bound volumes of watercolour plates.

Fonds shows Dr. Allan McMillan's activities as a country doctor in the Eastern Townships of the end of the 19th century. |a The fonds consists of 6 daybooks separated into 6 vols.: v. 1: 22 Apr. 1876-18 Sept. 1885, v. 2: 22 Sept. 1885-7 March 1887, v. 3: 15 March 1894-24 Feb. 1897, v. 4: 1 Aug. 1898-30 June 1900, v. 5: 1 July 1900-8 June 1905, v. 6: 12 June 1905-14 July 1908.

Fonds contains the final manuscript of Paediatrics in Canada, a text on the 6th Field Ambulance, C.E.F. by Graham Ross and a review of three cases of hyper-vitaminosis syndrome, with four X-rays from the Department of Pathology of the Royal Victoria Hospital.

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.
