Copy letter from Robert William Frederick Harrison to A M Blackamn, St Paul's Vicarage, Old Catton, Norwich 'I have received a letter from Miss Paterson stating that on of your slides was not replaced in the box after your lecture at the meeting of the Egypt Exploration Fund in our room on the 13th instant. I regret to find that owing to an oversight this was not discovered until yesterday, and I am now sending the slide on to you.' 22 November 1912
