FARADAY, Michael (1791-1867). Autograph letter signed 'M Faraday' to J. Martin Jones, Royal Institution, 30 December 1835, 4 pages, folio, (slight wear along one fold); and Thomas TELFORD (1757-1834), autograph letter signed to Messrs J.&R. Prossers, Architects, 28 November 1829, 24 Abingdon Street, Westminster, 1 page, 4to with integral address leaf with seal (minor tear at fold, some browning), concerning the Clifton Bridge.
Faraday gives his detailed opinion on 'the principle that the same bulk of a gas is abstracted by water whatever be its previous density from extraneous pressure', offering his theories by using ammonia rather than water; written in a period when he was engrossed in his research into electricity, to such an extent that it precipitated his illness the following year.
