 siderable period included most of the principal 

 geologists of Europe; as Freisleben, Mohs, Esmark, 

 d'Andrada, Raumer, Engelhart, Charpentier, Broc- 

 chi. Alexander von Hnmboldt and Leopold von 

 Buch went forth from his school to observe America 

 and Siberia, the isles of the Atlantic, and the coast

 burgh a Wernerian Society; and his lecture-room 

 became a second center of Wernerian doctrines, 

 whence proceeded many zealous geological ob- 

 servers; among these we may mention as one of

 were looked upon with great respect till the study 

 of organic fossils threw them into the shade. 



Smith, on the other hand, long pursued his 

 own thoughts without aid and without sympathy. 

 About 1799, he became acquainted with a few 

 gentlemen (Dr. Anderson, Mr. Richardson, Mr.

 discoveries; but the want of literary leisure and
