Copy letter from Robert William Frederick Harrison, to Dr Richard Tetley Glazebrook, Fellow of the Royal Society Harrison writes to explain a discrepancy which has occurred due to the Bank of England giving instructions for the purchase of stock for the National Physical Laboratory Pension Fund Account based on the sum given in the accompanying letter, £440 and 13 shillings, rather than the cheque itself which was for £440, 13 shillings and nine pence. This leaves a balance of nine pence which is being held in the credit of the Pension Fund Account, to be added to the sum next invested. 24 May 1907
