He then determined to adopt the medical profession, and studied at various hospitals in London, Paris, and Dublin.
On 16 February 1843 he was incorporated at the University of Oxford from Wadham College. He graduated Bachelor of Medicine on 22 June 1843, and the degree of doctor of medicine was conferred upon him by this university on 10 June 1859.
He then began to practise in Truro, and in 1856 he was appointed physician to the Royal Cornwall Infirmary, and he was also connected professionally with the Truro dispensary.
