Since the publication, iu 1866, of the 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," 1 to which 

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

 and foreign. 2 



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



1 'Memoirs Geological Survey,' 1890. 



2 For the foreign equivalents to English Pliocene strata, and correlation of foreign Tertiary 

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