DILUVIUM. 
Beds of partially rolled flints appear immedi- 
ately beneath the turf on the summits, and also 
in some of the valleys of the Downs ; and loam, 
clay, sand, gravel, and other diluvial debris, are 
spread over the surface of the regular strata 
tliroiighont the interior of the country, obscuring 
their outcrop, and forming the immediate subsoil 
of the district. These accumulations of water- 
worn materials have clearly resulted from the de- 
struction of the more ancient deposits ; the flints 
and gravel from the disintegration of the upper 
strata of the chalk ; and the loam, clay, &c. from 
that of the sands and clays of the Weald and Forest- 
Ridge. Large blocks of a siliceous sandstone, of 
which no regular bed now exists in this country, 
and of the ferruginous breccia of the tertiary 
formations, are also of frequent occurrence. It is 
in these accumulations of diluvial debris, that the 
bones and teeth of elephants, horses, and other 
quadrupeds, are discovered. We shall not, how- 
ever, in this place, dwell upon the inferences which 
may be deduced from these striking facts, but 
confine our remarks to a brief notice of the most 
interesting examples. 
The bed of flints, slightly rolled, which occurs 
on the Downs, immediately beneath the turf, con-
