London, Sampson Low, Marston, Low & Searle, 1873 . Hardback first edition and first impression, believed to be a 'deluxe' edition carrying bevelled edges to the boards. Original blue cloth with gold gilt. AEG. A near fine copy with bumping to the spine tips, a neat, but lengthy gift inscription dated 1872, some bubbling to the front pastedown and the rear hinge is weakening. Printer's sticker to rear pastedown as expected. All in all a very nice copy with bright boards and gilt. Three Englishmen, Three Russians and a local bushman take to the Kalahari to measure the arc of the meridian, but things take a turn for the worse when the British and the Russians declare war.
