A lovely pair of finely rendered hemispheric maps that are some of the most decorative maps produced in the 19th Century. Both with well colored vignettes and borders. Both maps show a circular hemisphere completely surrounded by vignettes by Warren, featuring whales, natives, and indigenous animals, with a fancy vine-style border.

The western map extends to include New Zealand and the Solomon Islands in the Pacific, and the Cape Verde Islands in the Atlantic. Alaska is Russian America, New California occupies all the west coast, Texas appears as independent, and the coast of Antarctica is somewhat defined.

The eastern map is colored by continent and includes major cities, topography and watershed. The "Mail Route" for the British Empire is shown in blue. It extends from Britain through the Mediterranean Sea, overland to the Red Sea, across the Arabian Sea to Calcutta, through the East Indies and around Australia with stops in Perth, Adelaide, Hobart (Tasmania) and Sidney.
