Letter from the Manager of the British Vacuum Cleaner Company, 25 Victoria Street, to the Secretary of the Royal Society, Burlington House, Piccadilly Dear Sir, We are in receipt of your letter of the 7th instant [NLB/29/405] and beg to inform you that two estimates were rendered you, and the cleaning was carried out on both of them. One for £14.10.0 less 4/- has been duly settled by you, but the one dated 18th July for £1.15.0. is still owing. When our Mr Booth called upon you, he must have overlooked the fact that a separate estimate had been given for cleaning the drawing room, dining room and study. We re-enclose statement herewith. Yours truly, For the British Vacuum Cleaner Co., Ltd., [Charles ?], Managing Director' [enclosure not present]. 14 October 1904
