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 witli 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 (6) 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. 



(6) 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 (b), 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.
