Referee's report by Harold Jeffreys, on a paper 'Probability and chance in the theory of statistics' by Maurice Stevenson Bartlett Sectional Committee: Mathematics Recommended for publication in the 'Proceedings of the Royal Society of London'. Disagrees with much of the paper but is uncertain what to recommend. Discusses the methods. 'I know the author, who is an intelligent person, but my impression is that he is not clear in his own mind about what he really believes, and would be benefited by having a bit longer to think things over'.
