Having adopted the medical profession, he proceeded in 1808 to Edinburgh, where he attended the lectures of Robert Jameson, and thenceforth his interest in natural history and especially in geology steadily increased. He moved to London in 1809, where he studied medicine and chemistry. In 1811 he presented to the Geological Society of London a description of the geological structure of the vicinity of Dublin, with an account of some rare minerals found in Ireland.[1] He took a medical practice at Northampton in 1812, and for some years the duties of his profession engrossed his time.
