Copy letter from an unknown correspondent, to Messrs C Pearson & Company, 90 Sidney Street, Stepney, E 'On April 21 I wrote to you to come & see some paper. You came the next day, & fetched it away in your van next week. We have never yet had the money for this load of papers. I have written once before, & must now insist that you will be good enough to send me postal order immediately'. 10 July 1891
