Paper, 'Reply to a note by Professor J E [James Emerson] Reynolds on the atomic weight of glucinum or beryllium' by T S Humpidge Humpidge writes: 'In the above-mentioned note of Professor Reynolds [see PP/3/23] the author criticises the results detailed in a paper which I recently had the honour to contribute to the Society, and draws an inference from the specific heats of different specimens of the metal which I cannot admit to be founded on facts. Professor Reynolds remarks that all the results obtained by Nilson and myself tend in one direction, viz., to a considerable, though irregular, rise in the specific heat as the impurities diminish.'
