|8 October 1900
|In reply to Sampson's application for a second copy of each of numbers 405 and 430 of the 'Proceedings of the Royal Society', the Society has never made it a practice to send second copies on account of the first having been lost through no fault of theirs. Offers to supply the numbers at marked price less trade discount.
