Leonard Jenyns (1800-1893)
Annotated books: The Jenyns library includes a number of volumes annotated by himself, by his great uncle Leonard Chappelow, or by other earlier owners. Of local significance is his own interleaved copy of Charles Cardale Babington's Flora Bathoniensis (1834) and its Supplement (1839), annotated with Jenyns' own botanical observations.
Meteorological Observations, from his Cambridge days to his organising and monitoring of the Institution's own weather station (set up in 1865).
Correspondence of 'men of science' with Jenyns, bound in four volumes by him - transcripts of these and other letters have been made - correspondents include Charles Darwin, William Jackson Hooker and Joseph Dalton Hooker, John Stephens Henslow and many other influential men of the 19th century - the Jenyns Correspondence is registered with the National Register of Archives.
Research notes and drawings, by Jenyns, Henslow and others, mostly on zoological subjects.
Scrap Books of meteorology and natural history, including one kept of reports of Bath Natural History and Antiquarian Field Club's activities as reported in the local newspapers. Jenyns was founder and long time President of the Field Club.
Bath Field Club (1855-1911)
Founded by Leonard Jenyns (founder members including Christopher Broome, Charles Moore and Harry Mingden Scarth), the Bath Natural History and Antiquarian Field Club, met regularly at the Institution. Its library and archives were acquired on the club's dissolution. They include catalogues of its library (1901,1935), minute book, a scrap book with notices and reports of meetings (1893-1910), correspondence and notices to members.
Christopher Edmund Broome (1812-1886)
Broome's botanical library and related archive items were given to the Instutution by his family after his death. Archives include his library catalogue. Annotated volumes include: Sowerby's British Fungi, many plates of which are annotated and with drawings of spores and other features not illustrated or mentioned in the text; books used to note species present in his herbarium and collection of fungi. Other items include lecture aids: botanical drawings on large sheets supplied with loops; ms. originals for papers addressed to the Bath Field Club, Bath Microscopical Society, Somersetshire Archaeological and Natural History Society, and others probably prepared for publication.
Charles Moore (1815-1881)
Catalogue of his geological collection (purchased by subscription after his death). Original ms. notes for papers, and watercolour strips depicting the order of strata at some of his collecting sites, these possibly used as lecture aids. Photographs of geological exposures visited by Moore, mostly taken by Henry Hoyte Winwood (1830-1920), his friend, biographer, and curator of his collection after his death.
Harry Mingden Scarth (d. 1890)
Scarth's own interleaved copies of his paper On the Roman antiquities discovered in Bath (1853), and book Aquae Solis (1864), heavily annotated and with a large amount of loose material which he filed in these volumes at the appropriate point. These include detailed plans and drawings of excavations, sketches of finds, and correspondence with other antiquarians regarding Roman remains in the Bath area, also original ms. notes and news cuttings of papers read to various societies. These have all been transcribed for ease of access.
Francis Lockey (1796-1869)
Meteorological Journals (1834-1869) with phenological and other natural history observations in the early years, and notes on photographic subjects, materials and processes, from ca. 1849 onwards.
