 to enter into a description somewhat detailed, of appearances at- 

 tended with considerable interest, and involving some difficulties. 

 We are yet, it is to be feared, in want of a theory capable of sol- 

 ving all the cases which the increased activity of geological research 

 is daily bringing to light. It is among difficult and unexplained 

 phenomena that we are to seek for the stimulus which will lead us 

 to pursue those researches on the multiplication of which alone we 

 can hope to found a true system ; and it is to a salutary distrust 

 of the all-sufficiency of any hypothesis, that we must look for pro-

 rock contains than for the purpose of examining those remarkable 

 geological phenomena which it exhibits. Except the account of it 

 in the travels of Faujas de St. Fond, I know not that any description 

 of this hill has been laid before the public. The peculiar opinions
