entrance to the caves, and destroyed portions of the “ Eaised Beach.” I should 
therefore consider the remains of the animals here found in the ‘‘Argile d hlocanx” to 
be foreign to that deposit, and as belonging to the Mammoth group. It was only near 
the base of. this angular rubble (2) that these derived remains were found. 
Another point of analogy rendered evident by the sections of M. Dupont, is the 
abrupt transition from the Paleolithic to the Neolithic deposits. This agrees 
precisely with what we have witnessed on the English coasts, where the stanniferous 
gravel of Cornwall and the angular rubble of Devonshire sharply separate the Raised 
Beaches and sands of Quaternary age from the alluvial deposits and forest growth of 
the recent period. The following (fig. 13) is one of the sections,* where the two 
deposits are seen in superposition.

2. Clay with angular fragments {Argile a hlocaux). 
3. Fluviatile beds with animal remains of Quaternary age. 
[I am not prepared with evidence relating to the Rubble-drift eastward through 
Germany, or to the northward of Belgium, but I may mention that Dr. Loete, of 
Utrecht, has called my attention to a deposit which covers some parts of North 
Holland, and is described by him under the head of “ Phenomenes pseudo-glaciaires.”* 
This drift, which seems to represent some phase of the Rubble-drift, is referred by 
Dr. Lorie to the warp of Trimmer, and trail of 0. Fisher. —J. P., July, 1893.] 
The Paris Basin. —Several sections of this drift have been noticed in the Paris 
Basin where deep valleys cut through high plains of Tertiary strata. The steep slopes 
and escarped edges of tliese valleys are generally covered with debris or a talus of 
recent formation, but sometimes of Quaternary age. The latter occasionally contains 
Mammalian remains, as at llltampes and La Ferte-Aleps (Seine-et-Oise), to south of 
Paris, and at Auvers and ITsle-Adam in the valley of the Oise to the north. 
At Auvers and ITsle-Adam the late distinguished geologist M. E. Hebert dis¬ 
covered remains of Hycena syelcea, Felis, Elef>hant, Horse, Ox, Irish ElJi, Red Deer, 
Eox? Anteloije? Hare and Rabbit A at Etampes there were Rhinoeeros and Bear 
also. The bones, which were numerous, were generally much broJcen. The rubble
