Dr. Roy O. Davies, of the University of Leicester, has sent me a neat proof of Theorem 3, p. 430, of my paper “Changing the Order of Integration” [1]. Perhaps other readers would appreciate this improvement, as I do; I therefore present it below, with his agreement, together with a consequent improved proof of Theorem 2. The counter-example, which is the main part of that paper, is unaffected.
