Letter from D Noel Paton to William B Hardy Cannot make the next meeting -- suggests that the next meeting of the Sub-Committee on Experimental Investigations be postponed -- approves of the memo but feels it is 'casting pearls before swine' with the Food Controller's lack of interest -- notes that 'Waller has one of his picturesque documents' and hopes that the Committee will not be 'beguiled' by it. 14 March 1917
