nxjLLETlS OV THE NATURAL HISTORY SOCIETV. 



1st. The formation is completely de- 

 Void of stratification. 



2nd. The striated stones are very of- 

 ten elongated in shape, showing that 

 they were worn by being pushed along 

 by some solid force. 



3rd. The character of the whole of 

 the contents of the clay— both organic 

 and inorganic, point to the fact that 

 some land force must have been at 

 work, to glean such a heterogeneous 

 mass of debris together. 



4th. The manner in which th'? ac- 

 cumulation was laid down, shows a dif- 

 ference in the method employd, from 

 that used to produce the sedimentary 

 deposits. 



5th. No marine life remains are 

 found in the clay, of the age in which 

 it was formed. 



6th. Similar deposits are now actual- 

 ly in process of formation in some 

 parts of the world, being laid down 

 by Glacial Agency. 



In conclusion, it may be remarked" 

 that it is still a debatable question, as 



to whether man's existence was coeval 

 with the Glacial Period. It probably 

 depends upon what is meant by 

 coeval. 



If it means with the later ice age, 

 which occurred after the warm Inter- 

 glacial Period, then, perhaps,, the query 

 may be answered in the affirmative, 

 as considerable evidence has been col- 

 lected which tends to show that man 

 was in existence then, but no trace of 

 his remains were found in the Bedfor- 

 shire Drift, The Cave and other de- 

 posits contain evidences, such as 

 chipped flints and stones, which seem 

 to indicate that he may have retreated 

 before the advancing ice which pro- 

 duced the Upper Boulder Clay. 



If man's advent did not occur until 

 after the drift was deposited, yet the 

 men who chipned palaeolithic stones 

 or polished neolithic flints must have 

 lived at a period very remote from us, 

 if we gage the time of their existence 

 simply by the measure- of historic 

 chronology.
