The former are documented by an account book, 1845-1848; ledgers, 1870-1889; and diaries, 1884, 1936; the latter by lists of stock holders, 1954-1960; and records of transfers of Morgan's common stock, 1954-1961. Also included are files of invoices, receipts and cheques, 1846-1852. Publicity materials largely centre around anniversaries.

The papers of "Jackrabbit" Johannsen reflect his personal, professional and recreational activities, mainly between 1934 and 1985. The largest part of the papers consists of correspondence with friends and organizations, particularly relating to skiing and outdoor life. Family relations are also covered. A series of brief journals provides a record of some of his daily activities, from 1948 to 1984. The remainder of the fonds include publications about Johannsen, photographs, maps and personal documents such as passports.

Fonds consists of manuscripts and typescripts of articles and lectures on literary topics. A few items reflect Walter’s interest in drama and his private life.

The literary addresses and articles fall into three subject-areas: German, French, and Indian. A series of lectures to the Montréal Goethe Society (1932, 1933, 1935, 1936) discusses Goethe's biography, his attitudes to music, and his dramatic works. Goethe is also the subject of a McGill lecture (1906) and an article for the University of Toronto Quarterly. In other lecture series, Walter treated Ibsen and the 20th century German novel (1936); as well, shorter studies of Adolf Schafheitlin, Superman in German literature, German bibliography, and an address to Shaar Hashamayim regarding the political conditions in Germany in 1933 can be found here. Addresses delivered to the McGill Cercle Français and to the University of Toronto discuss French phonetics, neologisms, symbolist literature, German universities, and Paul Lemaître. Walter's interest in Oriental civilization is reflected in a series of four lectures on Indian philosophy, religion and literature (1949) and an address on Yogis. His work as a book reviewer and drama critic is revealed by a file of clippings and typescripts.

Walter's 1936 production at McGill of von Kotzebue's “Die deutschen Kleinstadten” is documented by his annotated copy of the script and a scene design. This and other dramatic productions are the subject of photographs and newsclippings in a biographical scrapbook. The scrapbook also contains testimonials to Walter and clippings of articles by and about his literary activities, and about a case of alleged attempted poisoning at which he was the plaintiff.

Wallis' papers are grouped into three series: general scrapbooks, military scrapbooks, and military diaries. General scrapbooks, covering the years 1908-1977, contain letters, photographs, and printed materials relative to Wallis' career. Some volumes include his diary for the period, and all are heavily annotated. They cover all aspects of his career from high school to post-retirement, with special emphasis on his military career and social life. Military scrapbooks contain the same variety of materials for the period 1911-1969, but are devoted exclusively to Wallis' activities during the two World Wars, and his roles in the Black Watch and as an Honorary A.D.C. Military journals give brief reports of his daily activities form 1941 to 1945.

The project files which occupy most of the archives of J.T. Donald and Co. fall into two series: ordinary business and special assignments. Both series contain the firms report's, and correspondence. Special assignments were largely connected with wartime armaments production. A few files concern work for the Imperial Munitions Board in World War I, but most consist of reports for the Chemical and Explosives Branch of the Department of Munitions and Supply, 1939-1948. Ordinary projects involve consultation for food, pulp and paper, petroleum, and chemical manufacturies, as well as for some government departments, 1888-1940. Outgoing correspondence from 1881 to 1909 is contained in letterbooks. A file of legal documents, 1924-1946, refer to claims against the company, agreements, and partnerships. Also included are an undated notebook on chemical analysis, and scrapbooks and files of newsclippings of professional interest (e.g. reports of explosions caused by oil and gas) covering the period 1916-1958. There are also reports on mining and energy sources prepared by Donald alone and also in partnership with J.H. Ross for various private and government bodies.

Fonds consists primarily of Meek’s manuscripts of his keyboard and church music compositions, from approximately 1930-1975. Also included are programmes for his organ recitals, 1928, 1933, 1953-1957, 1960-1968, a scrapbook of clippings concerning his performance of the complete organ works of J.S. Bach, 1949-1950, and lecture notes and examinations for his McGill course in analysis, 1969-1973.

The Lyman-Scrimger Family Fonds consists of the papers of the Lyman, Scrimger and Johnston Families. Reverend John Scrimger's daughter married Walter Ernest Lyman and their daughter, Elizabeth, in turn married Wyatt Galt Johnston. Elizabeth's sister is Mary Minta Turnor.

The Lyman-Scrimger papers largely consist of approximately 42 cm of photographs. Two albums contain family portraits, while two others assembled by Albert Clarence Lyman (B.A., 1878) and Walter E. Lyman (B.A., 1881) also include pictures of McGill classmates. The large collection of unbound photographs contain a number of views of Western Canada taken ca. 1900, Montreal scenes, and travel snapshots taken in Europe (ca. 1905-1910). Two scrapbooks compiled by the Reverend John Scrimger contain newsclippings, poems, cards, letters, photographs, and memorabilia of a family or sentimental nature. The reminder of the papers consists of newsclippings, programmes and so forth related to members of the family as well as a few scattered items of correspondence, probably collected by Mrs. Walter Lyman.

The Johnston Family papers comprise Wyatt Galt Johnston’s laundry lists and grocery accounts, ca. 1899; a letter to Elizabeth Johnston from her mother in Lennoxville, 1906; H. Wyatt Johnston’s school reports, 1907-1911; and letters of sympathy and memorial cards sent to H. Wyatt Johnston on the death of his mother Elizabeth Johnston, 1943 and his aunt Mary Tunor, 1945.

Most of this archive documents the High School for Girls. The administrative records comprise prospecti for both High Schools, registers of attendance, 1875-1896, examinations, 1855-1858, 1884-1888, fees, 1863-1869, and corporal punishment, 1892-1896, 1949-1960, and memoranda from the Rector applying to either the boys' division or to both High Schools, 1897-1904. There are also working notes for teachers, 1902-1903, 1921-1931, and scrapbooks of programmes, clippings and notes concerning activities in both schools, covering the years 1913 to 1960. Examination papers, 1872-1882, a guest book, 1919-1943, an annotated address book of High School for Girls staff prepared by Principal L.M. Hendrie, 1911-1945, and photographic portraits of the Principals of the High School for Girls round out this series. Student activities are reflected not only in the official scrapbooks, but also in minute books, photograph albums and scrapbooks of the High School for Girls' Athletic Association, 1912-1913, Literary and Debating Society, 1906-1908, and English Club, 1935-1940. There are a large number of photographs of girls' sports teams, 1915-1941, as well as a scrapbook of clippings on the activity of High School for Girls Alumnae, 1953-1956.

The D'Aigle papers fall into three series: diaries, correspondence and a scrapbook of photographs and memorabilia. The diaries (1912-1914, 1927, 1935-1952) are largely devoted to a day-by-day account of prospecting journeys. Correspondence with members of his family, partners, prospective financial backers and government mining bureaus covers the years 1900-1959. The scrapbook contains personal mementos, newsclippings about D'Aigle, photographs of his journeys, lists of supplies for prospecting trips, and maps, some drawn by D'Aigle himself.
