About the author

Born in Yorkshire in 1775, he studied at St Catharine Hall and then Trinity College, Cambridge, where he was named second wrangler and second Smith's prizeman in 1796. He later became a fellow of Trinity, taught mathematics at the East India College at Haileybury, and published The Principles of Fluxions in 1810.

His life then moved more fully into the Church of England. In 1813 he became rector of Clapham after John Venn's death, placing him close to the evangelical circle associated with Clapham and with debates around the British and Foreign Bible Society, which he strongly supported. He was elected a Fellow of the Royal Society, later received a prebendal stall at Winchester Cathedral and became chancellor of the diocese in 1830.

In 1845 he was appointed Archdeacon of Surrey. Alongside his church offices, he published sermons, charges, and religious pamphlets. He died at Brighton on October 15, 1847.
