Copy letter from William Bate Hardy, Secretary of the Royal Society; to Egerton Grey Esquire; Biochemical Laboratory, Cambridge Comments that some of the articles included in Mr. Egerton Grey's account of his apparatus, like the cork borers, files and ordinary retort stands, are not of a kind which the grant was intended to cover. Also highlights the fact that the total sum of the grant was £100, which Mr. Grey exceeds in his account. 5 August 1920
