The accounting series consists of three account books detailing different financial dealings and assets of the Natural History Society of Montreal. The accounting details are varied, one being the treasurer’s ledger of income and expenses kept by Treasurers James Ferrier Jr. and E. E. Shelton (file 13.7); another showing closing account balances for 1905, 1914, 1915, and 1916 and sales clippings for properties: 52 University Street Property, 152 & 154 Drummond Street Property, and the 365 Mountain Street Property Diagram of the property of the Natural History Society (file 15.1); lastly an address book shows an alphabetical list of assets and their value, as well as a note in the front tracking “Field Day” surpluses and deficits from 1882-1890 (file 16.3).

This series contains documents related to Noel Noel-Buxton's personal life and financial transactions, created between roughly 1869 and 1948. Includes material related to Buxton's early education, dental health, and the Noel-Buxton Foundation. Also includes photographs and a drawn portrait of Buxton.

The arrangement of the series reflects the structure of the fonds when it was described by McGill archivists. This may reflect the original order or may be an arrangement that was introduced by Professor H. N. Fieldhouse, who acquired the fonds for McGill and spent many years conducting research in it. 

Series contains lithographic menu templates.

The series consists primarily of incoming correspondence to various administrative units of the Natural History Society. This includes letters to the Recording Secretary, the Corresponding Secretary, the Chairman, the Librarian (dealing largely with book binding costs), the Chairman, the Editor of the Canadian Record of Science (primarily acknowledging receipt of the journal), and the Museum Curator. While most of the series consists of loose documents, it also contains two “Letter Books,” which have indexes of whom letters were sent by or to. These letters are highly administrative in nature, dealing with the daily operations of the Society and not the personal correspondence of its members.

The letters have substantial gaps between 1872-1878, 1881-1884, and in 1895. Many of the loose letters were donated to the Blacker-Wood Collection bundled together and they have been preserved together. However, many of the other loose letters were sorted by year by the archivist or librarian who originally processed them.

Many notes, drafts, and miscellany relate to Edith Wharton and Percy Lubbock.

This series contains subject files related to Noel Noel-Buxton's political activities and interests, dating from between roughly 1880 and 1950. The records chiefly concern British politics, and the UK's involvement in world politics, including the First and Second World Wars, Anglo-German relations, the Balkans, Indigenous sovereignty and the treatment of Indigenous populations, the governance of colonies, slavery, refugees, and famine and poverty in Europe after the Second World War. Also includes several files related to Buxton's religious and political beliefs and Paycockes House, a historic 15th century home in Essex that Buxton purchased and restored.

The arrangement of the series reflects the structure of the fonds when it was described by McGill archivists. This may reflect the original order or may be an arrangement that was introduced by Professor H. N. Fieldhouse, who acquired the fonds for McGill and spent many years conducting research in it. Files contain a variety of document types, including reports, notes, correspondence, publications, newspaper clippings, and volumes of parliamentary debates.

The series consists of administrative documents such as notes and proposals on membership, correspondence, invoices, programs of the Society (1896-1897), pages from the Microscopical Journal (1890), newspaper clippings on varying topics and a notebook of the Field Day Committee (1887).
