Referee's report by Charles Vernon Boys, on a paper 'The elasmometer, a new interferential form of elasticity apparatus' by Alfred Edward Howard Tutton Sectional Committee: Physics and Chemistry Recommended for publication in Philosophical Transactions'. The descriptive part of the paper should be cut down by about a half to avoid tediousness. All the illustrations should be reproduced. Tutton does not seem aware of Henry Reginald Arnulph Mallock's paper in the 'Proceedings [of the Royal Society]', volume XLIX, page 380, where an apparatus with the same object is sufficiently described in about a tenth of the space. Mallock has given evidence of the excellence of his instrument by numerous results, Tutton up to the present has none. A set of observations on some standard material would have added to the value of the paper. Discusses the formula on page 35 said to be taken from Warburg.
