Highly detailed large folio world atlas, published by W & A.K. Johnston, one of the leading map publishers in the United Kingdom in the second half of the 19th Century.
The atlas was first published in 1861. The present edition is updated with additions and consists of 53 double page maps, provides a fine overview of the world, with special emphasis on the United Kingdom and British Colonies around the world, as well as a fine large map of the Western United States.
Some of the notable changes in this edition include separate maps for: Canada West ("rapidly increasing importance as a new field for emigrations") and Mexico (previously on the general map of North America). The United States takes up two double-sheets (split at the Mississippi River).
