Referee's report by George Frederick James Temple, on a paper 'World-structure and non-Euclidean honeycombs' by Harold Scott Macdonald Coxeter and G J Whitrow Sectional committee: Mathematics Recommended for publication in Proceedings. He can appreciate the general basis of the argument but isn't convinced by the geometry. It should be reported on by another referee. The idea is interesting and ingenious but is of a mathematical rather than physical interest. [Published in Proceedings of the Royal Society A, 1950]. Date received not given. 11 December 1949
