A late-18th century terrrestrial pocket globe with a celestial case

A fine pocket globe by brothers John Cary (c.1754-1835) and William (c.1760-1835), who had separate businesses as a map publisher and a scientific instrument maker respectively, but worked together to produce globes.
This globe was their first, and does indeed show the latest discoveries, for example those of Alexander Mackenzie in Canada, 1789. The routes of Cook's three voyages are also marked.
This globe was sold in different combinations: as part of an orrery and tellurian; as a pair with a celestial globe, with a map of the world in the time of Caesar as the case lining; and, as here, with the gores used for the matching celestial globe as the lining.
