  work of every denomination. The late Archdeacon Dealtry, for some years archdeacon of Madras, and latterly vicar of Maidstone, was his only son.



DEALTRY, WILLIAM (1775–1847), archdeacon of Surrey, born in 1775, was the younger son of an old Yorkshire family, from whom he inherited at his father's death a small landed property. He entered St. Catharine Hall, Cambridge, when quite young, and soon migrated to Trinity College. He was second wrangler and second Smith's prizeman in 1796, and a fellow of Trinity from 1798 until his marriage in 1814. He proceeded M.A. in 1799, B.D. in 1812, and D.D. in 1829, and held for some years the living of Walton, Hertfordshire. In 1802 he was moderator in the examinations of the university. On the foundation of the East India College in Hertfordshire (Haileybury) he was appointed professor of mathematics. In 1810 he published ‘The Principles of Fluxions,’ a useful manual for students, and was about the same time elected a fellow of the Royal Society. In 1813, on the death of the Rev. John Venn, Dealtry was made rector of Clapham, and as a fervent member of the evangelical party in the church distinguished himself in the controversy which arose on the formation in 1810–12 of the British and Foreign Bible Society, which he strenuously supported. On 25 Feb. 1830 he received a prebendal stall at Winchester, and was made chancellor of the diocese; in 1845 he was appointed archdeacon of Surrey. He died at Brighton on 15 Oct. 1847. Besides the work on ‘Fluxions’ he published a large number of sermons and charges, as well as pamphlets in defence of the British and Foreign Bible Society.



DEAN, RICHARD (1727?–1778), author, born at Kirkby-in-Craven, Yorkshire, about 1727, was the first curate of Royton Chapel and curate of Middleton, both near Manchester. He was also master of the Middleton grammar school. He wrote ‘An Essay on the Future Life of Brutes, introduced with Observations upon Evil, its Nature and Origin’ (Manchester, 1767, 12mo, 2 vols.), wherein he argued for the reasonableness of believing in the future existence of the lower animals. His conclusions were controverted by James Rothwell, master of the Blackrod grammar school, in ‘A Letter to the Rev. Mr. Dean of Middleton, occasioned by reading his Essay on the Future Life of Brutes’ (1769, 8vo). Dean died at Middleton on 8 Feb. 1778.



DEAN, THOMAS (18th cent.), musician, was born towards the end of the seventeenth century. He wrote music for Oldmixon's tragedy the ‘Governor of Cyprus,’ produced at the Lincoln's Inn Fields Theatre in the early part of 1703. On 30 Nov. 1709, at a benefit concert for Turner, given at Stationers' Hall, Dean was announced to perform ‘a solo of the famous Archangelo Corelli's’ on the violin. Burney remarks on this that it was the first time he had seen such a promise in the newspapers. At the same concert ‘several full pieces of musick for trumpets, hautboys, violins, &c., by Mr. Dean, Mr. Masheip, and others’ were announced.

Burney says that Dean was organist at Warwick and Coventry. On 9 July 1731 he took the degree of Mus. Doc. at Oxford, where his name was entered at University College. The date of his death and all details of his biography are unknown. His music to the ‘Governor of Cyprus’ was published, and some violin pieces by him are in the late editions of the ‘Division Violin.’ The library of Christ Church, Oxford, contains some manuscript church music by him, and in the British Museum (Add. MS. 31467) is some of his harpsichord music.



DEAN, WILLIAM (d. 1588), catholic divine, was educated in the English college at Rheims, and after ordination was sent on the mission in 1582. He was apprehended before 1585, being one of the priests who were banished at the beginning of that year. Returning to his missionary labours he fell again into the hands of his adversaries, and was tried and condemned on 22 Aug. 1588 for being made priest by Roman authority and remaining in this realm contrary to the statute of 27 Eliz. On the 28th he was drawn to Mile-end Green and there executed, together with Henry Webley, a layman, who had been convicted for aiding him.
