two. The paleolithic series would appear to be a higher development 
of the type from the raised beach. JI am aware, however, that rude- 
ness is not always a test of age; and that many things of a rude type 
are produced when an art is declining; but if this is sometimes the 
case, we must not allow ourselves to lose sight of the fact, that im an 
early stage human implements would be of a very rude kind; and 
taking into account all the evidence I have given in this Paper, 1 am 
inclined to the belief that, in the present case, rudeness does indicate 
age. I consider we have evidence, not of a decline of the art of 
making flint implements, but evidence of the art being in a compara- 
tively early stage.
