Michael Faraday (1791-1867) was one of the most important men of science in nineteenth century Britain. His discoveries of electro-magnetic rotations (1821) and electro-magnetic induction (1831) laid the foundations of the modern electrical industry. His discovery of the magneto-optical effect and diamagnetism (1845) led him to formulate the field theory of electro-magnetism@ which forms one of the chemistry@ together with his lecturing at the Royal Institution@ his work for the state (including Trinity House)@ his religious beliefs and his lack of mathematical ability@ make Faraday one of the most fascinating scientific figures ever. All these aspects of his life and work and others@ such as his illnesses@ are reflected in his correspondence. This volume@ in which just over 70% of the 841 letters are previously unpublished@ covers the latter half of the 1850s and most of 1860. Topics include: Faraday's work on regelation@ the transmission of light through gold and his attempts to bring gravity into his general scheme of forces; the offer by Queen Victoria@ and his acceptance@ of a Grace and Favour House at Hampton Court; his advice to Trinity House@ the Board of Trade and the Royal Commission on Lighthouses; his investigation of the deterioration of the stonework of the relatively new Houses of Parliament; the conservation issues surrounding the National Gallery's pictures; and his appointment by Emperor Napoleon III to be a Commander of the Legion of Honour. Major correspondents included the Astronomer Royal G.B. Airy@ the new Secretary of Trinity House P.H. Berthon@ the Birmingham glassmaker J.T. Chance@ the French chemist and politician J.B.A. Dumas@ the Assistant Secretary of the Board of Trade T.H. Farrer@ the German mathematician Julius Plucker@ the Cambridge trained mathematical natural philosophers James Clerk Maxwell@ George Gabriel Stokes and William Thomson@ Faraday's colleague at the Royal Institution John Tyndall and the Swiss chemist Christian Schoenbein whose daughter died while in London.
