is circular in all. In one jaw with very high horizontal branches, the two 
first molars are of equal size: that is a fact which is observed also in the 
jaws of the reindeer period of Furfooz. The molars have likewise only 
four tubercles. Finally, in two pieces there exists also a strongly marked 
rounded ; the glenoid fossz are narrow eep; the post-mastoideal 
part is very thick, and the depressions of the inferior cerebral lobes 
the inner surface are deep. Thi peculiarity is noticed likewise on a

rom what has been said above, it is seen that the Cave of the Nutons 
of Gendron was a sepulchral cavern. But when did it serve that pur-

burial indicates great antiquity ; it can scarcely be met with except in 
the dolmens, 
We have said that three fragments of coarse pottery were found at 
the entrance of the cavern. Mr. de Mortillet, who has examined them, 
describes them as follows: 
“Two of the fragments evidently formed a part of the same vessel, 
and traces are seen of the bourrelet which formed the opening ; the 
other is red on one side, black on the other. This pottery was made by 
hand, without any use of the wheel. It is very poorly baked, and con-— 
Sequently has not passed through the oven. Powdered calcite was mix Ja 
with the clay, to give it consistency, and prevent it from cracking while 
drying and especially on the approach of fire, the baking being done 
probably before the vessels were perfectly dry. The outer surface of the 
fragments shows a polishing which has left numerous little strie, as if it 
been done with a bunch of grass or straw dipped in a barbotte (fine
