This pair of globes are a later issue of Dudley's 1808 globe, with the date removed in the plate.

Biography
Dudley Adams (1762-1830) was the son of George Adams (c1704-1773). Dudley Adams's brother, George Adams, (1750-1795) took over the family business after the death of their father, and Dudley Adams worked independently at 53 Charing Cross, where he published new editions of his father's 305 and 460mm (12 and 18 inch) globes. In 1796, Dudley returned to Fleet Street and continued to operate there before becoming bankrupt in 1817.

The Adams firm does not appear to have ever designed a pocket globe of its own, but rather acquire the copper plates of John Senex, and thereafter produced versions of his pocket globe to be used in their tellurium. Dudley also acquired the copper plates for a pocket globe of James Ferguson, dating to 1756, which he updated and replaced Ferguson's name with his own.

Geography
The cartography is based on Ferguson's 1756 globe. There have also been several additions, including the tracks of "Cook's going out 1776" with the "Endeavour" and "C.n King's return 1780", and improvements to the coastlines of Australia and New Zealand according to Cook's discoveries. "New South Wales", "Botany Bay" and "Hawaii" are now labelled. The west coast of America has been filled in above California to include "Alaska" and "Behring"and "English Colonies" are identified.

All of the above additions appear in an Adams globe dated 1795. The present globe also includes the identification of "English colonies" in North America, suggesting it is a suggesting it is a later version, although it is undated.

Astronomy
The celestial gores are the same as Adams's 1808 globe, which in turn followed the cartography of Ferguson's 1756 globe.
