f;aves the red cement with bones pervades all the crevices as far 

 as they can be penetrated, which is generally very directly down- 

 wards. One chamber of the cave, whence these specimens have 

 been taken, was terminated by the cavity being stopped up with 

 soft diluvial earth, while the breccia formed the roof, and ad- 

 hered to the limestone rock forming the sides, and appeared se- 

 parated from the loose earth of the lower part by three layers 

 (like strata) of limestone, about an inch in thickness, and three 

 inches apart between, and in which the bones were in greatest 

 abundance, and generally upright, or having pneend in eiiqh 



The peculiar texture of the cement, led to a search for it on 

 other parts of the surface above limestone, and in other parts of 

 the country, and it was found precisely under the same circum- 

 stances as at Wellington Valley. 



1. Six miles north-east, on the opposite side of the Mac- 

 quarrie. 



% At Buree, fifty miles south-east ; and, on looking at some 

 denuded limestone-rock similarly situated in another place 

 (Molong), a small quantity was also detected in a crevice like an 

 overt ; which also when broken contained small boneSS^^^F^^^^^ 



The most remarkable facts connected with these bonesj and 

 this breccia, seem to be, 



1^^, That it occurs only in the neighbourhood of caves, but 

 yet distinct from those of the most open and permanent descrip- 

 tion. 



^JZ^, That although always reaching to the surface, it is di&. 

 tributed deeply and extensively in the crevices of the limestone. 



3d/^, That this particular substance never occurs, but in 

 combination with bony fragments ; that bones occur in such 

 quantity in this cement only ; that those of small and large ani- 

 mals are intimately mixed ; and that, although much broken^ 

 there is no appearance of their being water-worn, but that, on 

 the contrary, small angular fragments of bone hke saw-dust are 

 combined in such quantity in some caves, as to give a light 

 speckled colour to the cement, which is, by itself, red and 

 41Qhreous. 



^thly^ That in one case, where this cement was traced to 

 the surface, a large fragment or rock of it, as hard as limestone,
