Referee's report by Dudley Maurice Newitt, on a paper 'Splashes from underwater explosions' by H Kolsky, J P Lewis, M T Sampson, A C Shearman and C I Snow Sectional Committee: Physics Recommended for publication in the 'Proceedings of the Royal Society of London'. The results are mainly empirical, but nothing novel has been discovered and the discussion adds little to theory. The experimental method has serious limitations. No theory has been developed to account for the phenomena observed. [Published in the 'Proceedings of the Royal Society of London'] No received date. [1948]
