Referee's report by Horace Lamb, on a paper 'Fog signals. Areas of silence and greatest range of sound' by Henry Reginald Arnulph Mallock Sectional Committee: Physics and Chemistry Not recommended for publication in the 'Proceedings of the Royal Society of London'. The paper is very short. Refers to John William Strutt, 3rd Baron Rayleigh and his 'The Theory of Sound', one which the introduction of the current paper is largely based. Suggests the paper would be suitable as a short letter to Nature or the Philosophical Magazine.
