associated with Llephas antiquus, EL. primigenius, and ELquus fossilis, 
etc. Their age is probably post-Glacial. 
A second record by Mr. Clement Reid is of especial interest to us. 
He found Paleolithic gravels with polished pebbles at Savernake 
Forest, and his comments on the climate of those times are pertinent. 
He argues that it must have been milder than on the Continent, where 
steppe conditions were prevailing, and yet that ‘‘ we have indications 
of drought in some of the mollusca and small mammals—perhaps also 
in the extreme poverty of the flora’’.t Yet the paleontological 
evidence in favour of steppe conditions is still meagre. Lagomys 
pusillus and Spermophilus are known from the Ightham Fissures, 
while the Saiga antelope is recorded from the Thames Valley. These, 
in that they are quite typical steppe animals, should form good 
evidence of the prevalent climate. 
I think, therefore, that we are justified in putting this occurrence 
of wind-worn pebbles on record, as another possible link in the chain 
of evidence in favour of dry conditions verging on those of the present- 
day steppes having occurred locally in Great Britain in post-Glacial 
times. ‘The abundance of fluviatile deposits belonging to this period 
precludes the possibility of true steppes having existed over wide areas 
in our country. But at the same time, though the melting and 
retreating ice-sheet provided great quantities of water, yet the climate 
may have been fairly dry, especially if, as Mr. Harmer has suggested, 
the prevalent winds blew at that time from the east. It must, 
however, be confessed that the general prevalence of steppe conditions 
in this country is still very far from proven.

HE Keuper rocks of East Nottinghamshire occupy almost the 
whole of that part of the county, striking slightly E. of N. and 
W. of S., and dipping at a very low angle in an easterly direction. 
They have been described by many competent local observers such 
as the Rev. A. Irving, Messrs. J. Shipman, E. Wilson, J. F. Blake, 
W. J. Harrison, and A. T. Metcalfe; and also by W. H. Dalton and 
W. T. Aveline in several publications of the Geological Survey 
between 1879 and 1888. During the recent survey the succession
