A collection of documents from the life of Simon McTavish including a letter to his creditors and a series of legal opinions on the estate of Simon and William McGillivray. Documents' informational value is largely financial in nature.

There is business correspondence, 1792-1800, with letters from among others Alexander Mackenzie, Joseph Frobisher, Alexander Henry, Simon Fraser and Roderick Mackenzie. There are also minutes and resolutions of the Executors of McTavish in a bound volume; and a contemporary copy of the minutes of the executors of his will, 1805.

The fonds consists of seven articles on the topic of Education in Quebec by Sinclair Laird, published in The School from October 1925 to May 1926 (March 1926 was skipped). The articles are titled, in order, Historical, Administration, School Funds, The Training of Teachers, Rural Schools, The Jewish Problem, Compulsory School Attendance.

The collection consists of a selection of records reflecting Sir Arthur Currie's tenure as Principal of McGill University from 1920 to 1933. His administration was marked by the establishment of the Faculty of Music, the School for Graduate Nurses, and the Faculty of Graduate Studies and Research. Constructed during this period were Moyse Hall, the Roddick Gates, a Biology Building (now the F. Cyril James Administration Building), and additions to Royal Victoria College and Redpath Library. Currie died in office on 30 November 1933. His records form a part of the McGill University's executive and administrative records, RG2: Office of the Principal and Vice-Chancellor. The Principal is the academic head and chief administrative officer of the University. Under the original Charter of 1821, the Principal constituted with the Board of Governors and the Fellows (now the Senate) a body politic and corporate. Later amendments to the Charter and changes in the University statutes have not significantly altered the position of Principal. Ex officio, by virtue of his office, the Principal is also Vice-Chancellor of the University, a member of the Board of Governors and Chairman of the Senate. Frequently, it has been the Principal's vision and personality which have determined the course of McGill's development; therefore, the records not only document the administrative activities of the office, but also often reflect the character of the whole institution. Currie's records fall more or less into the three general series: external correspondence, internal administration and academic matters.

Hardinge's papers are divided into two series: manuscripts and correspondence. The manuscripts comprise about 550 documents, reports, memoranda, etc. relating to Hardinge's work as a career soldier and administrator. The Indian phase of his career is the least well covered. Many of these documents were written by others, such as the Duke of Wellington or Lord John Russell, though they contain Hardinge's marginal notes. Papers on the British Army cover such topics as religious services for soldiers, 1823-1844; the organization and reform of military supply departments, 1822-1830; an inquiry into British military education, 1822-1829; and the organization of the Medical Department, 1812-1828. Material on the Home Army covers the period 1814-1850 while material on Ireland, 1816-1843, concern not only the militia, but also more wide ranging economic, social and political issues, such as the commutation of tithes. Papers on British North America, 1815-1844, concentrate on defence of the St. Lawrence Valley and the Maritimes, with special emphasis on canals (Rideau, Lachine, Welland). The strength, distribution, health problems and pay of troops in India, 1846-1847; the fortification of Aden, 1825-1847; and military matters pertaining to the West Indies, Bermuda, Australasia, South Africa, Mauritius, China, the Iberian peninsula and the Crimea are also discussed. It should be noted that the Australian papers also contain a considerable body of civilian population statistics. Hardinge's files also contain materials on military finance, particularly army estimates, 1826-1844; half-pay and pensions, 1812-1832; pay and allowances, 1827-1841; and the finances of the War Office, 1803-1847. Finally, a section of miscellaneous papers includes addresses by Hardinge, memorials of civil and military officers, cases of military discipline, proposals for new weaponry, and some documents on the reorganization of the government in 1827. The only items of personal interest concern the duel between Wellington and Lord Winchelsea, in which Hardinge was Wellington's second. The Hardinge correspondence is of much the same character as the manuscripts. It comprises over 2,000 letters, the largest blocks falling in the periods 1828-1831, 1842-1844, and 1852. There is a particularly substantial body of letters from Wellington and Lord Londonderry. Supplementing these papers is a microfilm of Hardinge materials in Cambridge University Library. These place more stress on the Indian period, with a large number of letters from Sir Robert Peel.

Fonds consists of a notebook kept by Seymour when he served as mate on the H.M.S. Imperieuse during service on a China station. The notes give details about crew, sales, accommodations and watches, 1861-1862.
