These little maps are derived from Gibson's maps of the same titles that appeared in the Gentleman's Magazine in December 1758. The cartography remains the same, but Bell's maps lack the decorative title cartouche. The maps depict an unusual projection of the two hemispheres, and also show the major cities, rivers, and mountains. A. Map of the New Continent Exhibiting its Greatest Diametral Length from the River Plata to the Lake Assiniboils. The western part of North America is not depicted. A system of rivers and lakes stretch from Lake Superior towards the Pacific.

B. Map of the Old Continent Exhibiting its Greatest Diametral Length from the Point of East Tartary to the Cape of Good Hope.
