| Citation | Fellow and Tutor of Jesus College, Oxford. Distinguished for his researches on the reactions of gases under the influence of light, and on the theory of the propagation of the explosion-wave in gases. In his memoir, 'On the Rate of Explosion o f Gases' (Phil Mag,, 1899), he developed a mathematical theory of the explosion-wave which is practically identical with that published in 1906 by Prof Jouguet in the Journal de Mathematiques, and anticipated the method proposed by MM Jouguet and Crussard for calculating the specific heats of gases at high temperatures from the velocity of the explosion-wave. His work on the union of hydrogen and chlorine under the influence of light has shown, among many interesting conclusions, that the 'Period of Chemical Induction' is due to the presence of traces of impurity in the vessel.
