Glacial Deposits in Europe and America. In the April- 

 May issue of the Journal of Geerfogy,Yo\. Ill, No. 3. pp. 241-269, James 

 Geikie contributes a valuable paper entitled : "The Classification of 

 European glacial deposits." 



It is a clear and conscise resume of the evidence gathered by one 

 whose intimate acquaintance with the facts of the case enable him to 

 present the various stages which characterized glacial times in Europe- 

 From the earliest glacial deposits of northern Europe the Scanian to 

 the latest, the Upper Turbarian or sixth glacial period, Dr. Geikie notes 

 five interglacial periods and six glacial periods, which he designates 

 as follows : 



European Glacial and Interglacial Stages. 



XI. Upper Turbarian Sixth Glacial Period. 



X. Upper Forestian Fifth Interglacial period. 



IX. Lower Turbarian Fifth Glacial Epoch 



VIII. Lower Forestian Fourth Interglacial Epoch. 



VII. Mecklenburgian Fourth Glacial Epoch. 



VI. Neudeckian Third Inter Glacial Epoch. 



V. Polandian Third Glacial Epo< h. 



IV. Helvetian Second Interglacial Epoch. 



III. Saxonian Second Glacial Epoch. 



II. Norfolkian First Interglacial Epoch. 



I. Scanian First Glacial Epoch. 



This admirable paper by Dr Geikie is followed by another on 



"The classification of America's glacial deposits" 270 277, {loc-cit.) 



by Prof. T. C, Chamberlin in which the latter points out the relations 



which exist between the stages mentioned by Dr. Geikie in his paper on 



European glacial deposits and the stages in America. Prof. Chamberlin 



remarks: "Our knowledue of the formations that were deposited 



during the advancing stages of the glacial period in America is 



extremely imperfect." This strikes the key-note to a series of careful 



investigations which ought to be made in the lowest glacial deposits o f 



North America and specially in British North America such as wilj 



enable the correlations of the different stage in Europe and America to 



be more accuratelyestablished. Prof.Chamberlin attempts to correlate the 



Kansan formation with the Saxonian of Europe owing to their striking
