out it was not hiwh enough for a man to stand erect in. 
At its widest part it only measured about 13 feet 
(4 m.), whilst the furthest recess was less than 20 feet 
from the low entrance on the face of the limestone 
terrace. The deposits on the original floor were about 
3 feet in depth, and exhibited two strata or zones (fig. 41), 
an upper one, rather less than 2 feet in depth, and a 
deeper, a little over a foot in thickness. The upper 
stratum was sterile so far as our present inquiry is con- 
cerned, but the deeper one, a yellowish clay laden with

remains of extinct animals and implements of the 
Mousterian culture, has an immediate bearing on our 
search. The animals represented in the deeper stratum 
were the woolly rhinoceros, the reindeer, a Pleistocene 
form of horse, the boar, the ibex, the bison, the cave- 
hyena, and the Alpine marmot. The implements, over 
a thousand in number, were the typical products of the 
Mousterian period — the Mousterian " points," scrapers, 
and flakes. The remains of two distinct hearths were 
noted near the level of the original floor. 
The Mousterian stratum was observed to dip down 
into a depression in the floor, near the centre of the cave 
(fig. 41). In this depression, the abbes exposed the 
skeleton of a man — again of the Neanderthal type. The
