Cumer observes, that " In some countries, we find 

 numerous, and prodigiously large blocks of primitive 

 substances scattered over the surface of the secondary 

 strata, and separated by deep vallies, from the peaks 

 or ridges, whence these blocks must have been deriv- 

 ed."* 



Mr. Jameson observes that " numerous large blocks, 

 or masses of mountain rocks, are frequently met with, 

 in almost every country in Europe, and frequently 

 very far removed from their original situations. Swit- 

 zerland, and the surrounding countries, present nume- 

 rous and very interesting appearances of this kind. 



On the mountains of Jura, immediately in the line 

 of direction of the Vallais, and nearly to the height of 

 6000 feet, enormous blocks of granite are found resting 

 upon the lime stone rock of that range of mountains. 

 These blocks are of that species of granite, which 

 forms the mountains of Ornex, belonging to the group 

 of Mont Blanc ; hence, it is inferred that they must 

 have been transported by the force of water, from that 

 region to their present situation. ?? f 



Where large masses of rocks are found out of place, 

 in the neighbourhood of high mountains, as the Pyren- 

 nees ; we can easily conceive how those masses of gra- 

 nite and other rocks, are removed out of their proper 

 places, and deposited where they are, when we can ac- 

 tually see them hurried down the impetuous current, 

 seemingly, with as much facility as that of rolled peb-
