Made by Nathaniel Hill, this globe is marked with the equator, tropic, and polar circles and the ecliptic. The globe is mounted at an angle of 23.5 degrees. The longitude is marked every 30 degrees and numbered every 15 degrees; the latitude is numbered every 10 degrees north and south. The land mases are coloured. There is no Alaska or Eastern Australia and only a small section of New Zealand is drawn. The sea route taken by Admiral George Anson (1697-1762) on his voyage round the world between 1740 and 1744 is marked in red.
