Referee's report by Osborne Reynolds, on a paper 'The capacity for heat of water between the freezing & boiling points' by Howard Turner Barnes Sectional committee: Physics and chemistry Recommended for publication in Philosophical Transactions, in full. The title should be modified to omit 'mechanical' and throughout the paper all reference to 'mechanical' should be omitted. This research has been directed solely to the determination of the equivalent in terms of electric units and has not touched the determination of the equivalent in mechanical units. Notes the measurement of specific heats over intervals of ten degrees centigrade is terribly difficult if not impossible', to anything like a ten thousandth part, and any results must be received with caution.
