REV. RB. A. BULLEN, B.A., ON EOLITHIC IMPLEMENTS. 215 
of that cold condition gradually ushered in at the earlier 
time. Tor the same reason there is no marked and definite 
line separating the fauna of the Pliocene from that of the 
Pleistocene, for we find remains of the animals of the warmer 
period closely associated with those of the colder in the same 
deposits, and under conditions which show clearly that they 
lived in those areas at the same time.* 
I cannot do better than conclude this paper with the word 
of Professor Grenville A. J. Colet:— 
“Surely the existence in the Pliocene period of a man-like 
animal capable of making implements is to many of us one 
of the highest probabilities. The close of the Pliocene period 
has nothing mystic or magical about it, nor is it likely that 
man sprang fully armed from glacial furrows. Let us ask 
ourselves candidly on which side of the question does 
probability he.” 
In conclusion 1 have to thank Professor Rupert Jones, 
F.R.S., for loan of books and pamphlets, and also for critical 
help ; and Mr. Benjamin Harrison for access to and loan of 
his specimens.
