Fonds contains two diaries for 1917 and 1918, and one address book of Dr. Robert Arthur Bowie during World War I. It includes 29 diaries written by his wife Pearl Blanche Bowie and by his daughter Margaret E. Bowie, from 1916 to 1951. In addition, there are a large number of photographs and negatives.

The fonds documents A.D. Blackader's personal and professional life. The fonds contains correspondence, diaries, autobiographical notes, papers and lectures, certificates, diplomas, testimonials, article reprints, photographs, and some memorabilia.

The fonds contains chiefly the writings of Jeremy Walker on a variety of issues in moral philosophy and related literary topics. These writings, including anthologies, drafts of books and lecture notes, demonstrate the range of his eclectic interests from his formal studies of Kierkegaard and moral philosophy to his more personal intellectual pursuits concerning the literature of Kipling, Jane Austen, and Dostoyevsky, as well as the poetry of Woodsworth and reflections on Englishness. There are also examples of his published and unpublished poetry.

His more personal writings are in diaries that cover more than 20 years of his adult life and in contrast to his erudite writings on grand philosophical topics reflect his feelings and at times his dreams, on the state of his health, relationships with women, and recount the day-to-day events of urban travel and socializing.

His personal and family relationships are reflected by correspondence with family, friends and students, photo albums of travels to England and Greece, travel diaries document his summer activities from 1947 -1950, including lists of books read, drawings and photographs. As well, in a file titled Personalia (3) Apologiai Walker provides some personal chronologies, and reflects upon his writings and his life.

Fonds consists of originals, carbon and photocopies stemming from both the wartime and post-war phases of Currie's career. His wartime career is recorded in a copy of his battlefield diary for 2 June 1916- 8 February 1917 and commemorated in an album of signatures of the officers he commanded. Postwar materials comprise correspondence and speeches. The correspondence concerns various causes which Currie patronized and books for which he wrote introductions. His speeches (in 7 volumes, with some loose) are devoted to the war and its aftermath, politics, education, eulogies, speeches of welcome, Christmas and New Year's messages, dedications of war memorials and the like. Some are noted as having been written by Wilfred Bovey.

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 Ross family fonds consists primarily of records related to the student achievements of the Ross children and includes student notebooks, news clippings, convocation programmes, certificates, and memorabilia of the Red and White Revue such as songs, photographs and original songs. Edward Russell Paterson’s student notebooks in geology, petrography and English literature are included.

In addition, there are two diaries of William Stieven Paterson’s from his travels through Civil War battlefields in the southern USA and a trip to Cuba; 8 photograph albums depicting the Paterson side of the family; 3 scrapbooks of magazine stories for children, poems and household hints; and correspondence between Dorothy Jean Ross and the McGill University Archives.

From February 21, 1946, entries describe daily life in Montreal and at McGill, with detailed impressions of friends and acquaintances, often with full names and addresses. The final full daily entry is dated February 28, 1946. Following that, entries record major events, such as moving to Quebec in summer of 1949 or convocation, with acquaintances made and Tetley's descriptions and impressions of them, often with names and contact information. Other events noted include Provincial Congress at Quebec, September 1950; "Soirée à la Marine," February 10, 1950; summer in the navy in England, 1951; Boy Scout Campaign, February 1952. Final entries are undated, but the journal appears to end in 1952. The fonds also includes some items previously laid in to the diary, including one black and white photograph of a coastline (laid in before entry dated Sept. 18, 1945), 2 loose leaves with lists of names and some addresses and a postcard, and 2 doctor's notes certifying Tetley's vaccination laid in between pages 92 and 93.

Very few of the McLeod papers actually concern the Observatory. However, his work for the railways and in Newfoundland is documented, as are his views on the education and employment of engineers. The basic record for the early part of his career is a diary kept from 1870 to 1875, regarding student days and early work on the Observatory. An essay, "Winter under canvas" (1868) describes an early surveying job, and a letter from his father (1872) inquires about his academic progress. His work for the railways is documented by three letters of recommendation, and two letters (one from Stanford Fleming) on the work of his colleagues in the West. The Newfoundland survey (1875) is described in McLeod's diary, a manuscript essay "Across Newfoundland" (1876), his printed reports and three letters. His work at McGill is represented by six letters (largely official acknowledgements of appointments), and McLeod's manuscript notes on McGill history. McLeod's concern with the engineering profession is reflected in two addresses on education and professional development, and copies of about a dozen letters to Sir Wilfrid Laurier (1906-1908), C.A. McGrath and E.F. Wurtele (1912), largely on the employment of engineers in the civil service.
