Ten yeai's ago I brought forward some reasons for thinking that 

 a second, but smaller, glacier epoch occurred after the first had 

 passed away. These reasons, however, were based entirely on 

 some phenomena exhited by the river channels in Otago, which 

 seemed to imply a second elevation ; (1) for of course in the 

 South Island of New Zealand every upheaval must cause the 

 glaciers to advance and subsidence must make them retreat. In 

 my report just quoted I said " That all our lakes are not filled up 

 is probably owing to the second advance of the glaciers which 

 partially scooped them out again." But the evidence for this 

 statement is very slight, and I have not been able to add to it 

 during the last ten years. 



If now I should be asked to what then do you attribute the 

 ancient glaciers of the Australian Alps 1 I should answer, It is 

 more pi'obable that Mount Kosciusco once stood some three 

 thousand feet higher than at present, when Tasmania was joined 

 to Australia, and Central Australia was, perhaps, a vast lake ; 

 than that the temperature of the surrounding ocean should liave 

 been reduced ten degrees without any apparent cause, which is the 

 only alternative. 



NOTES AND EXHIBITS. 



J. Brazier, C.M.Z.S., &c., exhibited specimens of the shells, 

 dried ink-bags, and pigment of both sexes of Sepia plangon, Gray, 

 from Port Jackson, also similar preparations of Sepia Capensis, 

 from Bondi. He also exhibited mounted specimens of the valves 

 and mantles of Chiton spiniger Sowb., from Port Denison, and of 

 Chiton petholatus, from Port Jackson. 



Mr. Trebeck exhibited specimens of fungi from Fiji, all belonging 

 to the family of Polyporus; and a specimen of hard subcrystalline 

 Tertiary limestone, from Eucla, West Australia, containing a fossil 

 Pecten.
