Bones discovered in a cave at Kirkdale, in Yorkshire. 225 
the period succeeding the last retreat of the waters. I do not 
see why some of them may not also have fallen in during 
that earlier period in which the bears occupied the caves of 
Germany, and the hyaenas that in Yorkshire ; for some of 
the animals found at Kirkdale seem to agree in species with 
those that occur in the fissures ; but as they are at the same 
time not distinguishable from existing species, the argument 
arising from this resemblance is imperfect. The discovery 
of the extinct elephant, rhinoceros, hippopotamus, bear, and 
hyaena in this breccia, should it ever be made, would be 
decisive of the question. 
For an account of the bones accumulated in these fissures, 
I must again refer to the works of M. Cuvier, which con- 
tain more sound and clear philosophical reasoning on the 
early state of habitation on our planet, and a more valuable 
collection of authentic facts relating to the history of its fossil 
animals of the higher orders, than can be found in all the 
books that have ever yet been written on the subject. 
APPENDIX. 
It was mentioned, when speaking of Gailenreuth, that human 
remains had been discovered there in the same cave with the 
bones of antediluvian animals, but that they are of compara- 
tively low antiquity. 
Three analogous cases have been noticed in this country 
in cavities of mountain lime-stone, at Burringdon, in Somerset- 
shire, and in Glamorganshire and Caermarthenshire ; and 
these also are attended by circumstances which indicate them 
to be of post-diluvian origin.
