FLINT IMPLEMENTS FOUND IN KENT’S CAVERN. 365 
that the glacial period, or, more probably, periods, embraced the 
era of great submergence and also that of the last great elevation. 
I repeat that the interpretation I venture to put on the Kent’s 
Cavern facts is that the Hyzena first reached Britain during the 
last continental period, but that man occupied Devonshire prior to 
that. It must be unnecessary to say that if this be accepted it 
will follow that unless the earliest Devonshire men of whom we 
have at present caught sight possessed some means of navigation, 
they must have arrived here during the first continental period ; 
and that to this conclusion we must also be driven if, as seems 
probable, Devonshire participated to any considerable extent in 
the great inter-continental submergence. In other words, the men 
of the Ursine period of Kent’s Cavern were either of glacial, or, 
more probably, of pre-glacial age. 
At this announcement the following questions may be expected 
to press forward for consideration :—I1st. What light does Pale- 
ontology throw on the absence of the Hyena in the fauna of the 
Cavern Breccia? 2nd. What is the relation of this opinion 
respecting the age of man in Britian, to that expressed by Sir 
C. Lyell in the last edition of his great work on the Antiquity of 
Man, published in 1873 ? 
lst. Assuming it to be true that the Cavern Breccia was de- 
posited before the second, but not before the first, continental 
period, it must be admitted to be of great importance in this 
argument to ascertain, if possible, what mammals occupied this 
country during the earlier of these two periods; for, since no 
terrestrial mammal could have travelled hither in the intermediate 
period of great submergence, unless they made the voyage on 
icebergs, there should be nothing conflicting between the first 
continental fauna as found elsewhere and that of the Breccia. 
Bears, for example, may be reasonably looked for in the one since 
they are known to occur in the other; and, on the other hand, it 
would certainly be remarkable to find Hyena spelea in the first 
continental list of British Mammals, seeing that it forms no part 
of that of the Kent’s Hole Breccia. 
The most complete evidence respecting the mammals which 
occupied Britain during the first continental period appears to be 
that furnished by the Forest bed of Cromer, which according to 
Mr. Boyd Dawkins has yielded the following 26 species:—1. Sorex
