ANTIQUITY OF HUMAN RACE. 439 



The formations following each other from the surface, in 

 sections at St. Acheul, are the following : — 



Feet. Inches 



a. Surface soil . . . . .08 



b. Brown loam in four layers of different shades, 12 2 



c. White siliceous sand and light-coloured marl, 



with fine chalk grit and patches of flint 



gravel . . . . . 4 10 



d. Coarse subangular flint-gravel, with mam- 



malian remains and flint implements dis- 

 persed throughout, but chiefly at the lower 

 part . . . . .50

In the deposit d, have been found, at St. Acheul, remains 

 of Ehpihas primigenius, Rhinoceros tichorhinus, Equus fossilis, 

 Bos primigenius, Cervus somonensis ; at Abbeville, also, Cervus 

 tarandus prisms, Felis spelcea, Hycena spelwa, Ursus spclceus ; 

 at St. Eoch, Ehphas antiquus and Hippopotamus major. 



Flint weapons of the same large size and rude fabrication 

 as those found in the gravel bed d, at St. Acheul, were dis- 

 covered by Mr. John Frere, F.B.S. (" Archeologia," vol. xiii., 

 " An account of flint weapons discovered at Hoxne in Suffolk," 

 1800) in a bed of flint gravel, 16 feet below the surface, of the 

 same post-glacial age as that in the valley of the Somme. 



Flint weapons have been discovered in many caves mixed 

 indiscriminately with the bones of the extinct cave-bear and 

 rhinoceros. One in particular was met with beneath a fine 

 antler of a rein-deer, with a femur of the cave-bear, imbedded 

 in the superficial stalagmite in the bone-cave at Brixham, 

 Devonshire, during the careful exploration of that cave con- 

 ducted by a committee of the Geological Society of London in 

 1858 and 1859.
