Init none of tliciu ijolislied, and somt' bone implements of very 
gross fabrication. 
The man was very tall, and. if we jndge by the length of the 
thigh-bone (545 millimeters), his hight must have exceeded two 
metres (6 feet (i inches). The boy, who had not yet attained his 
manhood, measured l.GM metres (5 feet 8 inches). We must also 
remark the extreme wear of the teeth, very apparent already in 
the boy, and which in the man extended to their ver}' root. I 
have already said that the caves of Baousse Rousse yielded numer- 
ous bones of mammals, Init none of them belonged to the extinct 
species, not even to the reindeer which is found in the south of 
France even at a late period. On the other hand, no polished 
stone implement was ever found in these caves. We can there- 
lore give these men a pretty ticcurate date, and place their exist- 
ence, as I have said, at the end of the Quaternary or the begin- 
ning of the neolithic times. One cave remains as yet unexcavated. 
It belongs to the Prince of Monaco. Orders are given that the 
excavations shall begin next spring. If they produce anything 
(»f interest, 1 will not fail to report them to the readers of Scicurc.

THE SHORE-LINES OF ANCIENT GLACIAL LAKES.- 
15.V -J. E. Todd, Vermillion, S. Dak. 
As most are aware, there are areas of drift external to any ter- 
minal moraines, the origin of which is still in ilispute. On 
general principles, it would be expected that numerous lakes 
would have freciuently occurred during the Ice Age. As the ice 
advanced, streams would frecpientl}' be dammed, and their chan- 
nels more or less changed, and the weight of the ice. with its 
chilling effect, in level areas would not infre(|uently jjroduce a 
subsidence toward the ice, which would often beconu' tilled with 
the floods esctiping from the ice. 
Geike, in his '-Ice Age," last edition, draws a graphic picture 
of such lakes in central North America. Inferences derivt'd from 
the Merjelen sea, and similar lakes in the Alps, (Ireenland and 
the Himalayas, strongly urge the probability of much larger ones 
of the same kind during ancient times. Such have lieen found in 
■^Proceedings of tfie Iowa Academy of Science, 1891.
