The letters in this accrual were written between 1963 and 2003. The scope of the correspondence is national and international and includes both incoming and carbon copies of outgoing letters.

This series contains correspondence between members of the Hall family and their extended family members from approximately 1742 to 1899. Letters were written predominately from New England (especially Philadelphia and Andover), Quebec City, and Montreal. The contents of the letters chiefly concern family news (including deaths and births), with some letters related to business, political and military events, and genealogy.

The correspondence in the series is grouped into a file for each family member represented - usually the creation of the letters, though some files also contain letters they received. There is also a file of correspondence related to family legacies and genealogy, as well as a file of miscellaneous letters, created by senders who were unidentified or who only appeared once in this series. The files in this series are arranged in approximate chronological order.

This series consists of business and personal correspondence created by and received by James Morrison in his capacity as a trader and merchant. Most of the correspondence is between Morrison and his business contacts in Quebec, Ontario, the Northern United States, and England. Some letters are from family members and contain both business and personal news, including Morrison's nephew, Samuel Morrison, in Baltimore, Morrison's brother-in-law, Charles LePallieur, who worked as a fur trader in Ontario and the United States, and Morrison's son, Charles Morrison, who travelled to Jamaica in search of work. Many of the letters in this series contain interesting information about the price and availability of various goods, especially wheat, rum, sugar, and molasses.

The letters in the series are grouped by intervals of 5 or 10 years into files of roughly similar size: 1770s (Correspondence, 1771-1776), 1780s (Correspondence, 1781-1789), the first half of the 1790s (Correspondence, 1790-1795), and the second half of the 1790s (Correspondence, 1795-1800). The letters are arranged in chronological order.

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.
