Copy letter from an unknown correspondent, to Messrs Harrison & Sons, 45 St Martins Lane '[J T] Cunningham & [Charles Alexander] MacMunn (B.89) - I find that 1025 plates were ordered, & I suppose were all delivered to you. Of these it appears from your memo [memorandum] that 90 have been stitched in. You should therefore have in hand 935 and overs. Please send these back to E Wilson, Post Office Terrace, Cambridge, who will re-tint them & return them to you'. 13 February 1894
