consisted of large blocks and fragments of the Calcaire de St. Ouen which crops out 
above, with loam and finer debris generally at the base, and in which the bones 
occurred. The drift lies in crevasses, hollows, or pockets showing, according to 
M. Hebert, strong water action. This agrees very much with what we see in the 
rubble (or head) overlying the Raised Beaches—beds of finer rubble due to currents 
of small velocity succeeded by a final current of greater force. 
The “Montague de GenayT —An excellent description of this hill, and of the 
superficial drifts of the district generally, has been given by M. J. J. Gollenot, with 
whom I visited the section, which presents some exceptional features.* It is situated 
a few miles to the north-west of Semur, and consists of horizontal Liassic strata, 
capped by beds of “Calcaire d entroques” (lower Oolite) covered by a drift of red 
earth, aud is nearly isolated from the surrounding ranges. Extending for some 
distance along the south side of the hill, which rises to the height of 1430 feet 
above the sea-level, and of 526 feet above the valley, is a mass of breccia lying 
on the beds of the Upper Lias and descending, apparently, to nearly the base of 
the slope. It consists mainly of angular detritus of the “ Calcaire d entrocques ” in a 
red earth, and has been in great part converted into a hard breccia by calcareous 
infiltration. In one place this breccia contains a large quantity of bones. The teeth 
and more solid bones are generally intact, but the other bones are broken, some trans¬ 
versely, and others in the direction of their length. They show no trace of wear, the 
angles being perfectly sharp, as are also the innumerable splinters. The bones longi¬ 
tudinally split, M. Gollenot considered to have been broken by Man to get at the 
marrow, and others which are black, or partly black, to be carbonized by fire.t 
He also remarks that none of the bones showed any traces of gnawing, though 
remains of Garnivora. were present. In some parts of the breccia he found land shells 
— Pupa, Clausilia, and Cyclostoma elegans. The Mammalian remains belong to— 
Hycena spelcea. 
Canis lupus. 
Elephas primigenius. 
Sus scrofa. 
Equus. 
Bison prisons. 
Bos primigenius. 
Cervus elaphus.

In addition to these, Beaver and Wild Goat (Bouquetin) were mentioned at the 
Avallon Meetinm 
o 
M. Gollenot also found in this breccia many flint flakes, some of them trimmed on 
the edges and weathered white, with round and angular fragments of granite and 
quartzite pebbles, which he believed may have been used as hammers and trimmers
