1830.] On the Climate of the North-Western Mountains. 
But the singular and puzzling fact remains to be mentioned. The bones of the 
Mastodon, Elephant, Rhinoceros, Hippopotamus, Tapir, Hear, H\ seua, Stag, &c. 
which have been found in caves, and in the alluvial soil in many parts of Europe 
and Asia, have been discovered in alluvial gravel, covered by a very ancient Tra- 
chitic breccia at Mont Perrier. r lhese animals have disappeared from the earth, 
(for they are all of extinct species,) and are supposed to have been destroyed by 
the deluge ; yet here we find their bones covered by, or rather inclosed among 
volcanicVocks which must be regarded as postdiluvian, for the reasons already 
mentioned. The animals must, of course, have lived in the neighbourhood at the 
time when these volcanic rocks were deposited on the surface of the country. 
Shall we then infer that the deluge was only partial, and did not visit Auvergne ? 
Or shall we suppose that these animals lived after it, and were destroyed by some 
other catastrophe ? Shall we also suppose that all the changes we have described 
have taken place within 5000 years ? We do not pretend to see our way at pre- 
sent through these difficulties. Geology presents many problems which cannot be 
solved at the first glance ; but the proofs of a general deluge are so numerous and 
strong, that we have no doubt of means being ultimately found to reconcile the 
facts we have mentioned with its existence at or near the period commonly assigned 
to it.
