Born 7 September 1877, third son of the Rev W Morgan Jones, Rector of Marks Tey, Essex, and Emma Gray, his wife. He was educated at St Paul's School, as a capitation scholar 1889-90 and a foundationer 1890-95, and at St George's Hospital, where he won an entrance scholarship in 1895 and was subsequently house surgeon, house physician and obstetric assistant. He was also clinical assistant at St Peter's Hospital for Stone. While serving as surgical registrar at St George's in 1904 he took the London MS. He was appointed assistant surgeon and lecturer in operative surgery at St George's in 1905, and was assistant surgeon at the Seamen's Hospital, Greenwich. He was also joint teacher of operative surgery at the London School of Clinical Medicine. Jones seemed, like his contemporary T C English, who died a few weeks after him, marked for success. But a serious illness and operation in 1910 forced him to give up the strenuous life of a London consultant, and left him unfit for war service. In 1919 he took the appointment of chief examining surgeon to the Great Central Railway, where he did much useful work. During the second world war he served in the Observer Corps. He contributed papers to the Royal Medico-chirurgical Society and to the Medical Society of London. Jones was a man of modesty and charm. He never married. He lived at Little Seeleys, Beaconsfield, where he enjoyed his taste for natural history, fishing, and gardening. He died there on 11 July 1949, aged 71. His younger brother George Arthur Jones, LSA 1902, practised as an anaesthetist. Publications: Appendicitis at St Georgs's Hospital, statistical tables 1900-1902. *Med-chir Trans* 1905, 88, 535.
