mal," mingled with numerous others, in the same state of preserva- 

 tion, belonging to species of Halmaturus, Dasyurus, Hypsiprymnus, 

 Macropus, and other living forms. The cave itself is in the Miocene 

 trap (fig. 4) ; and the sides and top of the passages are smoothed 

 and polished by the friction of the backs and sides of the animals 

 passing in and out. 



The elevation of the ravine is, I think, about 1000 feet above the 

 sea-level, and 30 miles inland. The matter in the cave consists 

 entirely of a very dry, powdery, brown earth. There is not a particle 

 of moisture in any part of the cave, and no calcareous incrustations. 

 The bones are not in the least degree mineralized. When we found 

 it, all the passages were so completely filled up that no animal 

 larger than a rat could have entered them. It must, I imagine, have 

 been filled up during the Pliocene, or what I call the " post-trappean 

 gold-drift period." (See sections.) 



In various places round the coast I have found what I believe to 

 be Eocene tertiary beds. They consist chiefly of blue clays, with 

 septarian bands and nodules and fine sandy loam, full of selenite, and 

 very rich in fossils, — the whole being exceedingly like London Clay, 

 both in mineral character and organic contents. They are certainly 

 the lowest tertiary beds I have yet seen in this country.
