Since the publication, in 1866, of tbe First Part of this Monograph, much light 

 has been thrown upon the stratigraphical relations of the Crag deposits of this 

 country and abroad, so that many modifications of the views then held have 

 become necessary. 



The whole of the Pliocene beds of the British Isles have been exhaustively- 

 dealt with by Mr. Clement Reid in his " Pliocene Deposits of Britain,"^ to which 

 is appended a full Bibliography of works relating to Pliocene strata, both English; 

 and foreign.^ 



The latest views on the subject are embodied in the following classification,. 



1 ' Memoirs Greological Survey,' 1890.

 strata generally, consult Gr. F. Harris's " Approximate Correlation of the Tertiary Beds of Europe,"
