Copy letter from Robert William Frederick Harrison to E B Brown, 21 Porchester Terrace, Bayswater W 'Dear Sir, With further reference to your letter of the 7th instant, I fear our records furnish no additional information to that which you already have concerning Ramsden. Our records are confined to the bare fact of his election as a Fellow and the description of such of his discoveries as were communicated to the [Royal] Society. I have not been able to find you particulars of his domestic life.' 10 March 1908
