Letter from Walter M. Gilbert, Assistant Secretary, Carnegie Institution of Washington, Washington D.C., to the Royal Society, Burlington House, London, W., England The Carnegie Institution of Washington has sent a box of books containing publications from the past two years to the Royal Society via Judson Freight Forwarding Company. Despite instructions to prepay shipping charges, the box was sent with collection charges. Requests that the Royal Society send a statement of the amount paid to release the box, so the Carnegie Institution can reimburse them. 5 May 1919
