14 NOTE ON ELEPHAS MERIDIONALS. 



total absence of terraces. After a careful examination of the 

 western side of the valley, which rises less abruptly, and testing 

 several places on the same level as the deposit on the opposite side, 

 I found no traces of it. There was the same bed of hard stul>- 

 lx>rn clay (ylacicd ?), which caps the hill on the western side of 

 the valley, and differing only in being in contact with undisturbed 

 chalk. 



SECTION OF THE GRAVEL BED. 



1. Mould, about 3 inches. 



2. Chalk (rubble), 10 inches. 



3. Stiff red clay, 6 inches. 



4. Fine impalpable sand and flint (remains of Elephant), 3 feet. 



5. Sand and ferruginous gravel (small), 3 inches. 



6. Flint material waterborne, 15 inches. 



7. Sand and ferruginous gravel (larger than Xo. 5), 3 inches. 



8. Sand (the lower portion with different sized flints), 12 feet. 



9. Chalk. 



Of these six beds each shews the different conditions under which 

 it was laid down, torrential or placid, only one is fossiliferous, con- 

 sisting of flints of different sizes and of the finest impalpable quartz 

 sand. The largest flints and bones lie at the bottom, the lighter 

 above, where the sand predominates. Beneath this bed are two others, 

 separated from each other by a thicker bed, containing sand and 

 waterworn flints. The uppermost of the two consist almost entirely 

 of small, thin, flat, shell-like flints, not thicker than a threepenny 

 piece, very much oxydised. The lower one resembles the upper in 

 every respect, except in the size of the flints, which, although larger, 

 retain their flat shell-like character. The carrying powers of the 

 stream were evidently more powerful in one case than in the other. 

 The question which suggests itself is, as to what mechanical 

 agency was employed to sort these light and buoyant flints from 

 the rest of the material borne with them on the current. It would 

 be intelligible if other objects of all shapes and sizes and of equal 

 weight were present, but this is not the case in either of the two 

 beds. Many of the flints in the upper beds of the deposit are
