of the cave was an oval dome, which continued upwards in 
a circular shaft as far as my sight could reach ; and I found 
the sides in many places dotted with clay, and the ledges, as 
high as I could reach, thickly covered with it, of the precise 
colour and appearance of that filling the cave. The surface 
under the dome, or “ pot hole,” had also many pebbles scat- 
tered over it, and these were of the same rocks as the large 
drift boulders occurring on the surface. Much water was 
coming down this shaft, as also in several other places in the 
Victoria Cave, and it disappeared again through the floor, 
and especially at a point near the entrance, where a large 
aperture showed that the cavern continued to a much 
lower level than the lowest point yet reached. 
(4) Mr. Tiddeman’s section and description gives the 
stratification of clays in the interior of the cave as regular 
and as consisting of (a) lower cave earth (b) bone bed con- 
taining bones of older mammals (c) laminated clay, and (d) 
upper cave earth. 
So far as I can learn, however, I cannot agree that this 
correctly describes the interior of the cavern. I should 
adopt in preference the following description : 
(a) Lower yellow clay, the old floor of occupation of the 
cave about 1 foot thick containing large quantities of copro- 
lites, the dung of the older mammals, whose bones occur 
plentifully in it, and I believe this seam of clay will be found 
to occur throughout the cave at varying levels. 
(b) Laminated clays above and below the large masses of 
limestone which have fallen from the roof and which have 
been deposited by water from the surface. This clay 
contains pebbles, and occasionally larger pieces of rocks, 
such as occur on the surface. 
(c) Cave earth on the surface of (6), at varying levels, 
and which contained Roman remains. This earth occurred 
generally at parts of the cavern where the roof is not much 
fissured, and where consequently it has not fallen.
