In personal appearance, Fox was tall, spare, and erect, with a refined expression. Although he was somewhat reserved in manner, his sincerity and earnestness gave him a strong hold on those with whom he came in contact. He was a man of great benevolence, and was in the habit of placing his house at Rydal at the disposal of the Bishop of Bedford during the summer months for the use of invalided East-end clergymen and their families. Equally as a teacher and as an investigator and writer Fox ranked high. His cases were thoroughly studied, with special attention to the mental and emotional state of his patients, in whom he inspired great confidence. He was the first physician to save life in cases of rheumatic fever where the temperature was excessively high, by placing the patient in baths of iced water. His lectures were highly valued by the students, and the characteristic of his teaching was the ability with which the facts of pathology were made the basis of practical diagnosis and treatment. All his writings manifested great research and labour, and are encyclopædic on their subjects. Besides the works enumerated below, he had been for many years preparing a treatise on diseases of the lungs and an atlas of their pathological anatomy, works that were nearly complete at his death.
Later life
In April 1887, he was suddenly summoned to the deathbed of his eldest brother at Wellington. Thence he went northwards towards his home at Rydal for a rest, but was seized with pneumonia on the way and died on 3 May at Preston, Lancashire. He was buried at Taunton on 6 May 1887. A bust in the Shire Hall, Taunton, was unveiled on 25 October 1888. His first wife died in 1870; by her he left three sons and three daughters. In 1874 he married Evelyn, daughter of Sir Baldwin Wake Walker, and widow of Captain Burgoyne, who was capsized off Cape Finisterre during a gale on 7 September 1870. His second son was Henry Wilson-Fox, who became a director of many companies in Rhodesia, and a Conservative Member of Parliament.
