 Regards the clay with flints of Allogny as the oldest Tertiary deposit 

 in the Paris Basin. Believes that the origin of this great accumulation 

 of flints is due not to chemical but to mechanical means — probably to 

 an immense glacier, llefers to many other matters more or less con- 

 nected with the subject. G. A. L.

 Describes special sections of the Drift in parts of Saxony, and corre- 

 lates the subdivisions with those in Thuringia and the Hartz. Recog- 

 nizes (1) "older diluvium," consisting of gravels and sands on the high 

 plateaux ; (2) " younger diluvium," deposited after erosion of valleys 

 in the former and consisting of loess now on the sides of the river- 

 valleys ; and (3) " alluvium" of horizontally-deposited loam and river- 

 gravels in the bottom of the existing valleys. F. W. R.
