He was elected a Fellow of the Royal Society in May, 1926. His candidacy citation read: "Distinguished for his investigations in physical and mineralogical chemistry, including electrical conductivity, ionisation, and electrolytic equilibria in aqueous and non-aqueous solutions. Has greatly contributed by his own work and that of his pupils to the building up of a notable school of physico-chemical research at Oxford. During the war and afterwards has done valuable work in connection with gas services. Acted as Chemical Adviser to the Third Army in France. Appointed Assistant Director of Gas Services, GHQ. Later appointed Controller of Chemical Warfare Department, with the rank of Brigadier-General". He gave the address "Man's Use of Energy" as president of the British Association for 1949–1950.
