excavations in it. Some of those, in Kent's Cavern, accord- 
ing to Mr. M'Enery, had one end in the diluvium, and 
the other sticking in the crust of the stalagmite, which lies 
over it. But, according to his repeated assurances, the flints 
are never found at the bottom of the cave, or mixed with the 
bones of the hyaenas and bears in the lower part of the mud, 
though, as he argues, if they had been washed down from 
the mouth of the cave they would, from their superior 
gravity, have sunk even lower than the bones. He con- 
sidered the cave to have been inhabited by a tribe using the 
flint implements, after the deposition of the diluvium and 
before the deposition of the stalagmites ; and regarding the 
diluvium as the production of Noah's flood, he was naturally 
surprised that there should be traces of human population 
in this distant part of the world so soon after that event. 
No human bone has ever been found in the mud, the upper 
part of which contains the flints. We have therefore the 
same phenomenon as in the gravel beds of the Somme, 
the presence of the works of man, without any bodily traces 
of him. Such traces, however, are found in the stalagmite 
which immediately overlies the diluvial deposit — burnt 
bones and charcoal; and Mr. M'Enery distinctly says that 
these are not lodged in any artificial hollow, such as might 
have been made at a subsequent time, but simply repose on a 
stratum of stalagmite, which has itself been covered by a 
second stratum, to use his own expression, " Like substances 
deposited on a grave stone, and subsequently overlaid by a 
similar slab." At this depth, however, no decidedly human 
remains, no pottery or beads, have been found. 
Higher up again in the stalagmite deposit, human bones 
are met with in connection with flint implements and coarse 
pottery, and even metallic remains. In one place an iron 
spear head was found, and the jaw of a boar, which may have 
received its death wound from the weapon ; and it is probable
