T 



he purpose of the present Paper is 



(I.) to glance at the nature of the substance known by the 

 name of Flint, and to make some attempt to read the 

 riddle of its formation — a problem invested with unusual 

 difficulties : 



(II.) to indicate the kinds and characteristics of Flint 

 Implements, and to point out their wide distribution : 



(III.) to epitomise with clearness the Glacial Theory, in order 

 to a better understanding of the way in which the various 

 flint-workers were related to the periods of European 

 Glaciation : 



(IV.) to make a rapid survey of the races that have been 

 called Archseolithic, Palaeolithic, Mesolithic, Neolithic 

 Prehistoric and Historic : and 



(V.) to supply to the conclusions at which we shall arrive, 

 certain remarkable linguistic confirmations, many of 

 which will be now advanced for the first time.
