Copy letter from William Bate Hardy, Secretary of the Royal Society; to Sir Frederick [William] Andrewes, Chairman of the Physiology Committee and FRS Informs Sir Frederick [William] Andrewes that the paper by Leonard Hill, 'The formulae for the kata-thermometer', was turned down by the Physics Committee for publication in 'Proceedings A'. Notes, however, that the referee suggested it may be of more interest to biologists, and suggests sending it a biological referee. 3 November 1921
