208 KELIQULE AQUITANICLE. 



spective evidence is deduced now-a-days from so great a number of concordant 

 observations, and of material facts of so clear a significance, that minds the least 

 prepared to admit it are not slow to accept it in all its reality, when they will 

 but take the trouble to look and then judge conscientiously. 



" Permit me to take this occasion of requesting you to point out to the Academy 

 two discoveries of even more immediate interest in regard to my studies on the 

 geographical distribution of the Quaternary Mammalia. In the first place, the 

 discovery of the remains of a Marmot, of a new species, or at least different from 

 that of the Alps, in a cavern of the Dordogne, anciently inhabited by Man. The 

 second fact, still more important, is the occurrence, also in Pe"rigord, at another 

 Human Station of very great antiquity, of a number of bones of Ovibos mos- 

 chatus or Musk-ox, showing a state of fracture analogous to that of other animal 

 bones used for food by the aborigines. These bones of the Musk-ox were found 

 associated with the remains of the great Bears, the great Cave-cat (Felis spel<ea), 

 the Reindeer, Aurochs, Horse, &c., and in the midst of relics of human industry, 

 thus testifying to the persistence of a glacial climate at the time when Man was 

 already established in this region of Europe, now so temperate in climate. We 

 know, indeed, that the Musk-ox, at present exiled to Arctic North America, never 

 comes on this side of 60 ; in the early part of the Quaternary Period, therefore, 

 he came 15 of latitude further to the south in this district. It is deserving of 

 remark that M. Alphonse Milne-Edwards* has arrived at analogous conclusions 

 by his study of the fossil Birds from our caverns and other Human Stations of 

 P&igord."
