Referee's report by [Paul Adrien Maurice] Dirac, on a paper 'The geometrical representation of Milne's kinematical relativity' by [William Hunter] McCrea Paper reference code: A.416 Sectional committee: Mathematics Does not recommend the paper for publication. The model used is not Milne's but [Edmund Taylor] Whittaker's de-sitter model, as published in Proc Roy Soc [Proceedings of the Royal Society] A 133, p 96. States that the discussion of Milne's model is 'inadequate'. Refers to [H P] Robertson, article in Reviews of Modern Physics 5, p 62 (1933). [Not published in Royal Society journals but published in the Proceedings of the Edinburgh Mathematical Society, volume 5, issue 4, 1938, pp. 211-220]. Received 1 October 1937 [Stamp on reverse dated 3 November 1937, likely denoting date of review by Sectional committee] [September - October 1937]
