 He published in 1757 "Reflections on the Use and Abuse of Bath Waters," which involved him in a dispute with a Dr. Lucas and a Dr. Oliver, the two being the chief doctors of the city.He issued a pamphlet concerning this quarrel — "A Narrative of Facts demonstrating the existence and course of a physical confederacy, made known in the printed letters of Dr. Lucas and Dr. Oliver," 1757, but the controversy ruined Baylies's practice, whereupon he moved to London.In 1761 Baylies unsuccessfully contested the representation of Evesham in Parliament, and then petitioned against the return of one of his rivals, although he withdrew the petition before the day of hearing (15 December).
