274 PALAEONTOLOGY. 



imbedded in them the finely wrought flints which I have mentioned 

 above. It must be admitted on the other hand, that in order to 

 have been precipitated through a fissure, the presence of which can 

 be clearly traced to its summit, animals such as the reindeer, the 

 wolf, &c., must have dwelt at more elevated levels. At some points 

 of these human stations, these hearth-stones, the spoils of animals 

 belonging to extinct races are found ; at Montgaudier some rare 

 relics of the Hycena-speliea : at La Chaise, the Rhinoceros tichorhinus i. 

 in the hearth.stone of Laugerie, the elephant is represented by some 

 fragments of molars and a certain number of instruments. Already, 

 in preceding years, I had collected in the Fairies' grotto some molara 

 of the Elephas Primigenius and objects in wrought ivory, which a 

 preconceived idea made me eliminate too arbitrarily from the middle 

 bed, more or less properly termed the red or upper drift- 

 Last year 1 thought I ought to examine still more minutely the 

 Eairies' grotto. The principal point was to establish incontestably 

 the co-existence of man with extinct races and with species that 

 have migrated towards the north. My late excavations have fur- 

 nished me with corroborative proof of the first of these two facta. 

 When I began in 1858, I had, like all inexperienced explorers, pro- 

 ceeded by the tentative method, and I saw myself compelled, in the 

 presence of numei'ous obscurities, to suspend my judgment: The 

 most efficacious method of dispelling the reasons for my hesitation, 

 was to explore in succession the superposition of the beds, and 

 especially to exhaust the upper strata with a view to the study of 

 the lower drift. It was under these conditions, and when the inter- 

 mediate stratum (the red drift) had entirely disappeared, that an 

 intelligent and learned coadjutor, M. Eranchet, who accompanied 

 me to the caverns, drew out with his own hands at the base of the 

 lower stratum, and almost on the very rock, a human Atlas associated 

 with numerous bones of the bear and the hyaena of the caverns,. 

 The very aspect of this human relic, even apart from the circum- 

 stances in which it was found, would serve to indicate its origin. 

 This is the fifth example in six years of human bones obtained from 

 this lower stratum, and collected at diverse points, but always in 

 direct relation with extinct races, and under the same conditions of 

 burial, without any trace of a later convulsion. The floor of the 

 Fairies' Cave has fallen into decay at a certain number of points, 

 and separates the inferior layer from the middle stratum. After
