Referee's report by Andrew Gray, on a paper 'The effects of changes of temperature on the modulus of torsional rigidity of metal wires' by Frank Horton

Description

Sectional Committee: Physics and Chemistry

Recommended for publication in Philosophical Transactions. As the results are presented as both tables and curves some condensation may be possible. The elementary investigation of logarithmic decrement at pages 23 and 24 might be omitted and only the results to be used stated. Describes why the figures in the columns of one of the tables might be doubtful. All the curves might be given, but those for each metal experimented on could be grouped and re-drawn on one sheet. In general the paper seems a record of careful and accurate work, by a well conceived and accurate method, and its results form a distinct addition to knowledge of the effects of changes of temperature on the elastic properties of metals. The author might perhaps less sweepingly and confidently 'condem' the previous work of others. Gray briefly discusses the reasoning behind the length of wire used in his own experiments.
