Manuscript titled 'Localities for New or Rare Mosses in Scotland'.
The names Alexander McKinlay, James Stirton and John Shaw are mentioned as collectors in the manuscript, alongside three dates, 1861, 1864 and 1868. Although not definite, the handwriting in the documents compares very favourably to that of James Hardy (1815-1898), Secretary of the Berwickshire Naturalists Club and compiling a work on Mosses of Berwickshire at the end of the 1860s.

2 volumes of unpublished manuscript produced by Janet Rae in the early 1980s. George MacDougall may have typed the manuscripts. The idea was to produce something similar to a book already published, but it was considered too expensive and that there was not enough demand to publish this one. The manuscript does include illustrations, including at least one original pen and ink sketch by Alan McGillveray, and constitutes a description of Edinburgh's changing landscapes in c.1983.
The accession also includes 2x 2020 calendars marking the Society's 150th anniversary in 2019.
