Copy letter from Robert William Frederick Harrison, to Mrs Maria Gordon, 421 Union Street, Aberdeen In reply to Gordon's letter of the 12th, Harrison shall be able to use Gordon's headlines as a basis of the subject-index. There is nothing to prevent Gordon publishing a short account of the paper provided the account does not go beyond the abstract of the paper which had already appeared in the 'Proceedings of the Royal Society'. On a rough estimate Harrison calculates the cost price of he paper when published to be about 12 shillings a copy. 15 October 1896
