PLEISTOCENE CAVE-DEPOSITS. 107 



la Naulette was the abode of Palaeolithic man. This is shown 

 by the heaps of bones which have been split longitudinally for 

 the sake of the marrow — many of them showing the marks of 

 blows made doubtless with stone implements. Besides these 

 were found a human lower jaw and other bones. The animal 

 remains associated with them indicate a group of animals cha- 

 racteristically Pleistocene. Among these were mammoth, rhino- 

 ceros, horse, wild-boar, small-ox, goat, chamois, reindeer, common 

 stag, roebuck, marmot, squirrel, mole, water-rat, hare, brown 

 bear, pole-cat, wolf, fox, dog, wild-cat, and some birds, bat- 

 rachians, and freshwater fish. 



The Pleistocene deposits are overlaid as usual with an accu- 

 mulation of yellow clay charged with angular stones. 



The cavern of Goyet occurs in the valley of the Samson, 

 another tributary of the Meuse, at a height of about 50 feet 

 above the level of the stream. It contains five bone -layers 

 alternating with six beds of alluvial deposits. The fifth or 

 lowest level contained remains of the lion commingled with those 

 of the cave-bear which occurred in great abundance. The fourth 

 level indicated that during the time it formed the floor hyaenas 

 and bears occupied the cave. The bones of their prey were 

 those of man, lynx, pole-cat, wolf, fox, rhinoceros, mammoth, 

 horse, chamois, wapiti, the great Irish deer, reindeer, and ox. 

 Eemains of the lion, hyaena, and cave-bear occurred in great 

 abundance, and the evidence showed that these animals had 

 occupied the cave at successive periods. During the accumula- 

 tions of the fifth bone-bed it would appear that the lion was the 

 first occupant, and that he was succeeded by the bear. In like 

 manner during the formation of the fourth bone-bed the cave 

 was first a hyaena's den and afterwards became the haunt of 

 bears. The third floor was occupied by Palaeolithic hunters, the 

 relics of whose feasts occur in abundance. The flint implements 

 are of the primitive type found at Montaigle. The animal 

 remains of this level belong to the following species — cave- 

 bear, brown bear, badger, weasel or ermine, dog, wolf, common 

 fox, blue fox, hyaena, lion, hare, marmot, rhinoceros, mammoth,
