248 THEORY OF THE EARTH. 



as the formations of our neighbourhood are in its 

 hollows, form a great part of Germany and Eng- 

 land ; and the efforts which the naturalists of these 

 two countries have recently made according with 

 ours, and proceeding upon the same principles, com- 

 bined with those which had been previously tried 

 by the school of Werner, will soon leave nothing 

 to be desired with respect to our knowledge of 

 them. Messrs de Humboldt and de Bonnard in 

 France and Germany, and Messrs Buckland and 

 Conybeare in England, have furnished the most 

 complete and most instructive accounts of them. 



The subjoined table, in which not only the se- 

 condary formations have been arranged, but the 

 whole series of strata, from the oldest known to 

 the most modern and most superficial, has been 

 politely furnished me by M. de Humboldt, to 

 adorn my work. It may be considered as an epi- 

 tome of the labours of geologists up to the present 

 period *.
