Bevieius — Quaternary Be'posits of the British Isles. 423 



information concerning William Smith's geological labours may be 

 expected of him, for he states that " I have examined the collection 

 of maps in the London Geological Society's library, which I am 

 cataloguing at the Society's request ". Perusal of the present work 

 will make all its readers anxious for the appearance of another.

The Correlation of the Quaternary Deposits of the British 



Isles with those of the Continent of Europe. By 



Charles E. P. Brooks, M.Sc, F.G.S. Smithsonian Keport 



for 1917. pp. 277-375. 



A PAPER of considerable importance to students of Pleistocene 



-'-^ geology. It contains a summary of the chief writings upon the 



Pleistocene beds of various European countries, and an account 



of the British deposits. This summary will be found to be very 



useful to workers amons these little-understood accumulations, 



and will save much reading of literature of various foreign countries. 



The author naturally attempts correlation of the British deposits 



with those of other countries. " In general the relations of the stages 



appear to be as follows : — 



Cold j)eriod . . Pre-Chellean. 



"W • J (Chellean. 



^ * ■ 1 Chelleo-Acheulian. 



Cold j)eriod . . Acheulian-Mousterian. 



Warm period . . Mousterian. 



/ Aurignacian. 

 Cold period , . j Solutrean. 



(Magdalenian." 

 It will be seen that this classification differs in many respects 

 from those of other writers. One feels that the time has not yet 

 arrived for correlations over wide areas. Mu^ch more evidence must 

 yet be obtained, but the author's paper will afford help to those 

 occupied in obtaining that evidence.
