Copy letter from [William Bate Hardy, Secretary of the Royal Society], to Dr [Charles James] Martin, Lister Institute of Preventative Medicine, Chelsea Gardens, Chelsea Bridge Road, S.W.1. 'I enclose a copy of a letter [CD/19/68] received from Sir Hugh Anderson, the Master of Gonville and Caius College, Cambridge. I have marked the copy confidential and am sending it to Sir John Rose Bradford, Sir [William] Leishman and Dr [Henry Hallett] Dale, as well as to yourself. The suggestion made in Sir Hugh's letter seems to be a practical and good one.' 2 April 1925
