been a very efficient conductor, and to have never used a bâton, but to have conducted with his naked hand. His last appearance in public took place on 10 July 1871, when he played one of the two pianofortes at the first performance of Brahms's ‘Requiem’ in England. Potter died on 26 Sept. 1871, and was buried on the seventy-ninth anniversary of his birthday. A portrait of him by Bendixen and Seguin was published in 1838.
Though his published works extend to Opus 29, they are rarely heard nowadays. They include nine symphonies, four overtures, three pianoforte concertos, chamber music including a sestet, Op. 11, three trios, Op. 12, and some string quartets; pianoforte studies in all the keys written for the Royal Academy of Music; an Italian cantata founded upon Byron's ‘Corsair;’ and additional accompaniments to Handel's ‘Acis and Galatea,’ a stage version of which was produced at the Queen's Theatre in 1831 under George Macfarren [q. v.] He was sometimes taunted with being a ‘servile imitator of Beethoven and others, and that he sacrificed too much for originality’—a feature which it is not easy to recognise in his works (Georgian Era, iv. 533). As a teacher and as principal of the Royal Academy, he exercised considerable influence among contemporary English musicians. He edited Mozart's pianoforte works, and, among literary papers, was author of ‘Recollections of Beethoven’ (Musical World, 29 April 1836) and ‘Hints on Orchestration’ (ib. 1836–7).

POTTER, RICHARD (1799–1886), scientific writer, was son of Richard Potter, a native of Westmoreland, who became a corn merchant and afterwards a brewer at Manchester. Born in that town on 2 Jan. 1799, he was educated at the Manchester grammar school, which he entered in 1811 and left in 1815. On leaving school he went into a Manchester warehouse, and was for some years engaged in mercantile life, but without success. His leisure time was devoted to scientific pursuits, more especially the study of optics and chemistry. In one or both of these subjects he had Dr. John Dalton [q. v.] as his tutor. In 1830 he wrote an article on metallic mirrors in Brewster's ‘Scientific Journal,’ and at the first meeting of the British Association in 1831 he read three papers. The next year he read two papers, and in 1833 three others. The attention given to these contributions induced the author to prepare himself for admission to one of the universities. He accordingly early in 1834 commenced to study classics under a private tutor, with the view of entering Queens' College, Cambridge. He obtained a scholarship at that college, and graduated B.A. in 1838, being sixth wrangler. In January 1839 he was elected a foundation fellow of his college, succeeding to the medical scholarship, then vacant, as he intended to study medicine. He proceeded M.A. in 1841, being then a licentiate of the Royal College of Physicians. He never practised medicine, but devoted himself to the teaching of the physical sciences. He was professor of natural philosophy and astronomy in University College, London, from October 1841 to April 1843. In the latter year he went to the university of King's College, Toronto, Canada, but in August 1844 returned to London, where he resumed his professorship at University College. This appointment he retained until July 1865. The remainder of his life he spent at Cambridge, where he died on 6 June 1886, aged 87. He married, on 11 April 1843, at St. Pancras Church, London, Mary Ann, daughter of Major Pilkington, of Urney, King's County, Ireland. She died, without children, on 16 April 1871.
He published the following works, in addition to fifty-nine or more contributions to journals and transactions of scientific societies:
- ‘Elementary Treatise on Mechanics,’ 1846.
- ‘Elementary Treatise on Geometrical Optics,’ 2 parts, 1847–51.
- ‘Physical Optics: Nature and Properties of Light,’ 2 parts, 1856–9.
- ‘Treatise on Hydrostatics and Hydrodynamics,’ 2 parts, 1859–87.

POTTER, ROBERT (1721–1804), poet and politician, born in 1721, was educated at the free school of Scarning, Norfolk. He matriculated from Emmanuel College, Cambridge, Bishop Hurd being slightly his senior in standing, and graduated B.A. in 1741, but did not proceed to the degree of M.A. until 1788, when he received substantial preferment. For some years he was curate of Reymerston in Norfolk; he was probably the Robert Potter who held from 1754 to 1758 the rectory of Crostwick in that county; and on
