contemporaneously with the Reindeer, in France. 325 
Upon one of these slabs, which has reached us in an incom- 
plete state in consequence of an ancient fracture, we can distin- 
guish the fore quarters of a probably herbivorous quadruped, 
of which the head must have been armed with horns, as far as 
can be judged by the uncertain lines, which enter but slightly 
into this rather hard rock. In the other slab we recognize more 
readily a head, with the nostrils clearly marked, and the mouth 
half open, but which has its profile-lines interrupted in the 
frontal region by a sort of obliteration resulting from an appa- 
rently artificial friction posterior to the preparation of the en- 
graving. A little in front upon the same slab there is the 
design of a large antler, which, if it really belongs to this head, 
would lead us, as you were the first to suggest, to refer it to 
the Elk. 
Besides the ossiferous deposits of the interior of caves, which 
are so numerous in the Périgord district, we may also investi- 
gate there the analogous accumulations of organic débris which 
rest against the great escarpments of the cretaceous rocks in 
that region, and are sometimes sheltered merely by more or less 
overhanging projections of the rock. These exterior deposits 
likewise abound in worked flints and in fractured bones of ani- 
mals (horse, ox, ibex, chamois, reindeer, birds, fishes, &c.), 
which have evidently served as food for the indigenous popula- 
tions at this ancient period of the age of stone. The remains 
of the common stag are very rare, as are also those of the wild 
boar and the hare. We have found some isolated teeth of the 
gigantic Irish deer (Megaceros hibernicus), and some detached 
plates of the molars of the Mammoth (4. primigenius), exactly as 
we observed them in the hearth of the funeral feasts of the an- 
cient burying-place of Aurignac, without being able to explain 
for what useful purpose these dentary laminz were preserved 
thus isolated*, 
It is likewise in these exterior stations that we have collected 
the finest worked flints, particularly at that of Laugerie-Haute, 
where there seems to have been established a manufactory of 
the fine lance-heads worked with little chips upon the two faces, 
and with the margins slightly undulated. But we have probably 
found only the refuse of this manufactory, as very few specimens 
were entire amongst more than a hundred fragments which we 
obtained. 
* This reminds us that, in the grotto of Les Eyzies, we have found a part 
of the cortical portion of an elephant’s tusk bearing traces of human work. 
We also collected there a metacarpal bone of the small digit of a young 
Felis of great size (Felis spelea?), on which are seen small cuts and nume- 
rous scratches, produced by a cutting-tool, exactly like those which are 
observed upon the bones of reindeer or horses which have been eaten by 
men,
