1889. | NEW YORK ACADEMY OF SCIENCES, 133 
at Namur, entitled ‘‘ L’Homme Contemporain du Mammouth 
a Spy,” consisting of thirty-one pages of text with ten litho- 
graphic plates ; also in a more elaborate memoir published in 
the Archives de Biologie, Tome VII., 1886, by Julien Fraipont 
and Max Lohest, both officers of the University of Liége. 
Through the courtesy of M. Lohest, both these reports have 
been presented to the speaker. [ These were exhibited at the 
Academy, together with lantern views of the crania and skele- 
tons which formed the subject of the memoirs, and of which he 
had been permitted to make a personal examination. | 
The excavations of Messrs. Du Puydt and Lohest were con- 
fined to the outer chamber of the cave and the terrace at its 
entrance. The bottom of the cavern was occupied by a sheet 
of made earth, from three to twelve feet in thickness, and above 
this a mass of fragments of the roof, which had fallen during 
the long interval since the occupation of the cave by prehistoric 
man. When the limestone fragments were removed, the sheet 
of made earth was found to include three layers, which con- 
tained bones and implements of different ages. The upper one 
contained some wrought flints, with a few bones of deer, mam- 
moth, and bear. The bones had been intentionally broken, and 
the flesh which once covered them had been used for food. 
This layer was from two to three feet in thickness, of a yellow 
color, very calcareous, and sometimes passed into stalagmite. 
Only the upper part of this bed contained relics, which had evi- 
dently been left by the last occupants of the cave. 
The second ossiferous layer was from two to twelve inches in 
thickness, was red in color, and contained in great abundance 
flint implements, fragments of bone, and wrought and orna- 
mented objects of ivory. The animals represented in the col- 
lection from this layer are the woolly rhinoceros, the horse, the 
hog, the stag, the Irish elk, the reindeer, the sheep, two species 
of ox, the mammoth, the cave-bear, the badger, the fox, the 
wolf, the martin, the cave-hyena, and the cave-lion. The flint 
implements are all of rude form and evidently belonged to the 
Paleolithic age; the wrought objects in ivory are very numer- 
ous, and some of them are decorated with incised lines making 
a kind of herring-bone figure and evidently designed for orna- 
ment. ‘There are also beads, earrings, pendants, etc., wrought 
_with considerable skill and intended only for ornament. 
The third Jayer was yellow in color, contained angular frag- 
ments of limestone, had a thickness varying from a few inches 
to a metre, and rested on the rocky bottom of the cave. This 
layer contained a few rudely chipped flint implements, the bones 
of the following animals: the woolly rhinoceros (Rhinoceros 
tichorhinus), the horse, the stag, the reindeer, the ox (Bos pri-
