amelioration of climate, retreat of the glaciers, and consequent 

 moving northward of the reindeer, the conditions of existence 

 materially changed. It is maintained by some naturalists that 

 the man of Cro-Magnon followed the reindeer north, that the set- 

 tlements remained for a long time uninhabited, and that the man 

 who made the polished flint implements is another and distinct 

 race neolithic man, the earliest man of the present period. On 

 the other hand, it is held that the polished flint race is but a de- 

 velopment of the Cro-Magnon. In support of this it is claimed 

 that in the upper levels of a rock shelter at Sorde, in the depart- 

 ment of the Basses-Pyr^n^es, human bones of the Cro-Magnon 

 type and cut flints were found, but with them a narrow, thin

blade and a triangular dagger, which are very similar to the 

 finest productions of the neolithic age. The most plausible conclu- 

 sion would seem to be that many, but not all, of the Cro-Magnon 

 men followed the reindeer and retreating ice northward, and that 

 those remaining amalgamated with the neolithic immigrants, ac- 

 cepting in a measure their industries ; thus we have the mixtures 

 of the implements of palaeolithic and neolithic man. 



The most recent of the races of fossil man have been grouped 

 by MM. Quatrefages and Hami under the name of the Furfooz 

 race, from Furfooz in the valley of the Lesse, Belgium ; here a 

 complete station, comprising a grotto where they lived and a 

 burial grotto, was found. As before mentioned, a race allied to 

 this is found in the Grenelle basin near Paris. Grouping on cranio- 

 logical characters, and considering a head found at La Touchere 

 in a bank of the Seille as an allied form, we have in this group
