1 The Principles practically gave the death-blow to the catastrophic school of geologists. By its support of G. P. Scrope

 forces of the globe.' Prof. G. A. J. Cole. 



' It will always rank as one of the classics of geology, and must form an early part of the reading of every man who 

 would wish to make himself an accomplished geologist.' -Sir Archibald Gertie.
