Cii PROCEEDI^"GS OF THE GEOLOGICAL SOCIETY. [May 1 898, 



re-entered some of the caverns, redisturbing in part the earlier 

 contents and depositing some of the mixed drift over that 

 previously in the caverns. 



While these caverns were occupied as dens by the hyaenas, 

 northern and southern animals commingled in the valleys and on 

 the great plains reaching out from them to the area now covered 

 by the Irish Sea. 



Prom numerous examinations made of undisturbed Glacial 

 deposits in Wales, the North of England, and Scotland, it has 

 also been proved very clearly that the extinct mammalia, whose 

 remains are found in association with the implements of Palaeo- 

 lithic man in caverns, must have lived there before those deposits 

 had been laid down, as their remains alwaj'-s occur at the base or in 

 the lower parts of the Drift, and never above it. Further, there is 

 not a particle of evidence to show that these extinct mammalia 

 ever revisited those areas after the close of the Glacial period. 



Before vacating the Chair I wish to express my warmest thanks 

 to you all for the honour which you conferred upon me 2 years ago 

 when you elected me your President. I further desire to thank 

 the Council, Officers, and permanent staff for the unvarying kind- 

 ness and ready assistance which they have extended to me on all 

 occasions during my term of office. 



My friend and successor, Mr. W. Whitaker, P.E.S., from his long 

 connexion with the Society and with the Geological Survey, is so 

 well known to you all that it only remains for me now to tender to 

 him my heartiest wishes that he may find his term of office as 

 pleasant and enjoyable as that which has fallen to my lot.
