A notice is appended by M. DE HUMBOLDT at the close of the 

 second volume of " Kosmos," stating, that the first portion 

 of that volume, viz. "On the Incitements to the Study of 

 Nature," was printed in July 1846; and that the printing 

 of the second portion, viz. "The History of the Physical 

 Contemplation of the Universe," was completed in the 

 month of September 1847. 



From page 100 to the conclusion of the text, the 

 Translation, in its progress through the press, has had the 

 advantage of being compared with the original by the 

 CHEVALIER BUNSEN. 



February 21, 1848.
