of other portions of the Appalachian series, as described by Prof. 

 H. D. Rogers and Mr. Hall, bear so striking a resemblance to 

 those more recent effects, which have given rise of late to such 

 deeply interesting speculations, that it would seem unphilosoph- 

 ical to refer the two to diffei^ent mechanical causes. He there-
