Copy letter from Robert William Frederick Harrison to Dr D [Dunkinfield] H [Henry] Scott, Foreign Secretary of the Royal Society 'In reply to your letter of January 28th, the separate papers from Phil[osophical] Trans[actions] were not issued as early as 1871. It is open to you to purchase the part in which Professor Williamson's paper appeared, viz, Trans Part II, at one third of the published price - £2.5.0, so that the net cost would be fifteen shillings. Perhaps you will send word whether you wish to adopt this course.' 29 January 1913
