TRAVELS OF ALEXANDER VON HUMBOLDT. 

 Travels and Researches of Alexander Von Humboldt : 

 being a condensed Narrative of his Journeys in the Equi- 

 noctial Regions of America, and in Asiatic Russia ; togeth- 

 er with Analyses of his more important Investigations. By 

 W. Macgillivray, A.M. 18mo. Engravings. 45 cents. 



Humboldt is the most illustrious traveller of his day. Nothing seems 

 too vast, too varied, too wonderful, or too minute for the keen eye, pene- 

 trating intellect, and unwearied exertions of this extraordinary man. A 

 botanist, zoologist, statist, and philosopher, the genius of this great wri- 

 ter seems to have been peculiarly fitted for surveying the varieties and 

 immensity of the physical world ; and he accordingly takes the foremost 

 rank of all travellers, dead or living. — Dihden. 



This work has been justly called by a competent judge, " a work of gi- 

 ^ntic extent and richness, to which the modern literature of Europe 

 can hardly offer a parallel." — Encyclopadia Americana.
