Booklet, 50pp., published in Yokohama in 1880, with annotations in ink throughout. A sheet of paper is tipped into the front cover, handwritten with the following title 'Addresses registered with Reuters Telegram Co. Limited.', with an accompanying sheet of paper giving instructions for using the telegraph code. A separate sheet of paper dated 9 June 1880 gives the 'Kerosine Code' for Messrs John Gillingham &amp Co. of Kobe. It is presumed that the booklet and papers were used together.
