When at the Rio Negro, we heard much of the indefatigable labours of this naturalist.

M.Alcide d'Orbigny, during the years 1825 to 1833, traversed several large portions of South America, and has made a collection, and is now publishing the results on a scale of magnificence, which at once places himself in the list of American travellers second only to Humboldt.)
