Copy letter from Robert William Frederick Harrison to Philip Norman, 45 Evelyn Gardens, SW 'Dear Sir, I am greatly obliged by your two letters of June 14 and 18 and for the information you give in them. I can only regret that we have not the opportunity of referring to the correspondence which took place, because we should be very glad to know the arguments which were relied upon behalf of your Society and which induced the Treasury to refund the cost of your new boiler.' 23 June 1909
