Copy letter from James Hopwood Jeans, Secretary of the Royal Society; to Sir Richard [Tetley] Glazebrook, Chairman of the Physics Committee and FRS Informs Sir Richard [Tetley] Glazebrook that they have received a paper from [Charles Vernon] Boys by Professor [Alexander Eugen] Conrady, 'A study of the balance'. Notes that Boys has clearly read the paper with care and believes the author has found methods of reducing the errors of the ordinary balance. Suggests getting the opinion of someone at the National Physical Laboratory on it. Also informs Sir Glazebrook of a paper by Professor [John Oliver] Arnold, 'On the correlation of the chemical constitutions of "true steels" to their micrographic structures', and suggests [Walter] Rosenhain as a referee. 15 December 1921
