This pocket globe has a cartouche in the North Pacific that reads “A New / GLOBE of the / Earth / by James Ferguson.” A broken line shows the route taken by George Anson during his 1740-1744 global circumnavigation. The Antipodes to London is shown, as are the Chinese Wall and monsoons in the Indian Sea. California appears as a peninsula. The globe is provided with a case made of dogfish skin, with an inverted celestial globe on the inside.
James Ferguson was an astronomical and philosophical lecturer and instrument maker who hailed from Scotland and settled in London. He introduced this globe in around 1756, and transferred his globe business to Benjamin Martin the following year.
