The Work from which the present Volume is translated consists of extracts from the Author's Journal, accompanied by his recollections and observations. The absence of chronological arrangement will be sufficiently accounted for, when it is explained that the zoological investigations for which the journey was undertaken frequently required the Author to make repeated visits to one particular place or district, or to remain for a considerable time within the narrow circuit of a few miles; and sometimes to travel rapidly over vast tracts of country. Disclaiming any intention of making one of those travelling romances, with which the tourist literature of the day is overstocked, the Author has confined himself to a plain description of facts and things as they came within the sphere of his own observation. But though Dr. Tschudi lays claim to no merit beyond the truthfulness of his narrative, yet the reader will no doubt readily concede to him the merit of extensive information, and happy descriptive talent. His pictures of Nature, especially those relating to the animal world, are frequently imbued with much of the charm of thought and style which characterizes the writings of Buffon.
