Finely engraved image of the comparative heights of the principal mountains (and volcanos) of the world, showing Dhaulagiri as the highest in the world and Chimborazo as the highest in the western hemisphere. The heights of the Himalayas, unconfirmed but presumed to be the world's tallest, are attributed to the 12th volume of The Asiatic Society's Asiatick Researches, first published in Calcutta in 1816.
The names and heights of the various mountains are given in the margins, with nearly 100 mountains listed. Chemist and physicist Joseph Louis Gay-Lussac's 1804 hot air balloon ascent to an elevation of 22,900 feet is also noted.
John Thomson (1777-ca. 1840) was a commercial map publisher active in Edinburgh. He specialized in guide books and atlases and is primarily known for his Atlas of Scotland (1832) and the New General Atlas, first published in 1817 and reissued for the next quarter century. The New General Atlas was a commercial success—it was also published in Dublin and London—and it compiled existing geographic knowledge in compelling ways for a wide audience.
His Atlas of Scotland introduced new geographic information and was the first large-scale atlas of Scotland to be organized by county. It provided the most-accurate view of Scotland available before the Clearances. Work on the atlas began in 1820 and led to Thomson’s bankruptcy in 1830 due to the high costs of gathering the latest surveys and reviewing the required materials. Despite the publication of the atlas, Thomson declared bankruptcy again in 1835.
