Copy letter from Robert William Frederick Harrison to Mr F E Parsons, Crown Place, Kentish Town, NW 'Dear Sir, On December 19th last I wrote asking you to kindly return the bill relating to an account for £1. 7. 6 which we paid by cheque on October 15th. If the original bill has been lost I shall be glad of a copy of it. Failing that, the matter must be reported to Sir David Bruce, the Director of the Sleeping Sickness Commission.' 19 January 1909
