Colonel Sir Henry James was appointed head of the British Topographical and Statistical Depot of the War Office in 1857. His work primarily consisted of military mapping in conjunction with the Ordinance Survey of the United Kingdom. As part of this work, James and his assistant, J. O'Farrell, developed the unique geometrical projection seen here. His intention, as outline in his most important work, the 1868 Atlas Portfolio, was "to map the world" based upon his sheetline and the Greenwich Meridian. Unfortunately, his grand project was never taken up by his successors and never reached completion.
