FLINT IMPLEMENTS FOUND IN KENT’S CAVERN. 359 
consists of two principal planes or facets sloping in opposite directions 
from a transverse ridge about midway in its length, the flatness is not 
strongly pronounced. At the but-end, on the convex face, it retains 
much of the original surface of the nodule, and shows that it was made 
from a well-rolled pebble. The rest of the surface has a somewhat 
orange-coloured tint, derived, no doubt, from the matrix in which it 
was found. On one or two small facets near the point, however, this 
tint does not appear, but the true whitish colour is displayed. .. . 
Within the substance of the implement, and near the point, there is 
a small irregular quartz pebble. . . . This specimen was found on 
Nov. 27th, 1872, at a depth of 16 inches in the undisturbed Breccia, 
under a block of limestone measuring 24 x 14 x 14 inches, adjacent 
to the left wall of the ‘Arcade,’ 73 feet from its entrance, that is 
about 160 feet from the nearest external entrance of the Cavern. 
No animal remains or other objects of interest were found near it.” * 
In proceeding to the chronology of the Cavern, the following 
facts show that the implements of the Breccia belonged to an 
earlier period than those of the Cave-earth : 
Ist. When the two deposits occurred in the same vertical section— 
and this was invariably the case when flint or chert tools were met with 
in the Breccia, —the Cave-earth overlay the Breccia in every instance. 
2nd. Though thus lodged on the same area, the two deposits 
were very dissimilar, as has been already stated; the Breccia being 
essentially a dark-red sandy paste containing a very large number 
of subangular and rounded fragments of grit of the same colour, 
which, though derivable from adjacent loftier eminences, the 
Cavern hill could not supply; whilst the Cave-earth was made up 
of a light-red clay with small angular fragments of limestone. 
3rd. These two deposits were separated by a sheet of Crystalline 
Stalagmite, in some places almost twelve feet thick, formed after 
the materials of the Breccia were deposited, but before the intro- 
duction of the Cave-earth commenced. 
4th. After the Stalagmite just mentioned had sealed up the 
Breccia, it was, in extensive parts of the Cavern, broken up by 
some natural agency, and much of the latter, if not of both, was 
dislodged, and carried out of the Cavern before the first instalment 
of Cave-earth was deposited. 
5th. The Cavern faunz during the periods represented by the
