164 GEOLOGY OF THE SECOND DISTRICT. 



In conclusion, I would remark, that in drawing up my account of these rocks, I have felt 

 that much less interest will ever be attached to them, in consequence of their entire destitution 

 of fossils. They are to be considered, however, as furnishing us with a knowledge of that 

 state which immediately preceded the existence of organic beings ; they furnish one link in 

 the liistory of the earth, which is necessary for us to possess before we can by any means 

 consider our knowledge as being at all complete, or as full as is necessary if we would reason 

 correctly.
