A few years later a more important application of the magnetoelectric machine was demonstrated— one that had many implications for the future. Frederick H. Holmes showed, in 1853, that a magneto might be used to run an arc light, much to the sur- prise of the well known authority on electricity, E. Becquerel.^^ The latter subsequently declared that ^''Mechanics Magazine, 1849, vol. 51, pp. 271-272; Illustrated London News, October 2, 1852, vol. 21, p. 295. 3" Samuel Timmins, Birmingham and the Midland Hardware District, London, 1866, pp. 488-494. 31 British patent 13536 (February 28, 1851). 32 D.
