Three years later he left Dublin in consequence of disagreements with other fellows of the college as to the propriety of his prescribing the powder called after Robert James, M.D., a remedy of which the composition was kept secret by the proprietor.
[1] He settled as a physician at Brighthelmstone (later called Brighton) in 1759, and in 1761 published A Short History of Brighthelmstone,[2] then a town of about two thousand inhabitants, of which the main purposes were to give an account of the climate and other advantages of the place as a residence for invalids,[1] and to promote the drinking of mineral waters and seabathing.
[1] Relhan used to reside and practise at Brighton during the bathing season,[1] and from 1758 to 1767, he had an office on Southampton Street in London.
[1][5] His son, Richard Relhan was a fellow of King's College, and published a renowned account of the plants growing near Cambridge.
^ Relhan's predecessor, the eminent physician Dr. Richard Russell (1687–1759), a resident of Lewes and Brighton (which are close to the chalybeate spring of Hove), had advocated drinking seawater.
