Copy letter from Robert William Frederick Harrison, to J Lawrence-Hamilton, 30 Sussex Place, Brighton The Royal Society cannot assist him very much in his enquiry on the literature of pearls. There is no mention of the subject in any volumes of 'Proceedings [of the Royal Society]' from issue 54. Dr Harley does not appear to have published anything later than the paper Lawrence-Hamilton quotes in 'Proceedings [of the Royal Society]'. Acknowledges the copy of Part I of his monograph on the subject. 5 March 1902
