Born in Aberdeen on March 8th, 1809; he studied at Aberdeen, also in London at the School in Great Windmill Street, and at Joshua Brookes's in Blenheim Street. He became one of the foremost London practitioners, practising first in Greek Street, Soho, then at 3 Bedford Square, London, WC. In conjunction with Dr John Snow he began the administration of anaesthetics, and at Charing Cross Hospital tried bichloride of methylene and published *Experiences with Bichloride of Methylene* in 1868. He was for long Treasurer of the Medical Society and in 1869 its President. He constantly took part in debates, and his quiet courtesy and earnestness were a set-off to a certain nervous anxiety to express himself fairly. He acted as Referee and Inspector to the British Home for Incurables, also as Surgeon to the Recruiting Staff, East India Company's Depot, Soho. In 1870, owing to failing health, he moved to East Cowes Park, Isle of Wight. A long-standing affection of the heart and aorta, complicated towards the last by inflammation of the lungs, caused his death on March 12th, 1877, and he was buried in Whippingham Churchyard.
