water in the artesian beds was derived not from Cretaceous, but 
from Triassic rocks was definitely suggested, chiefly on litho- 
logical grounds, by the Rev. J. M. Curran! Mr. R. L. Jack, the 
Government Geologist of Queensland, in his able paper to the 
Australasian Association for the Advancement of Science at 
its Brisbane meeting, threw further light on this subject, and the 
Triassic Age of the strata penetrated in the Coonamble and Moree 
artesian bores was last year definitely proved by Mr. Pittman. The 
results of his important observations Mr. Pittman has already 
communicated to this Society, and he gives me to understand, 
that not only are the Coonamble and Moree bores drawing their 
supplies of water from the Triassic beds, but in all probability 
the Walgett bore also, in which the magnificent supply of from 
five to six million gallons of water per twenty-four hours has 
recently been struck. Mr. J. EH. Carne, F.a.s., has likewise 
furnished important reports upon the lately discovered chromite 
deposits of the Gundagai-Tumut district, the newly discovered 
mercury deposits on Yuilgilbar Station, Clarence River, and on 
the auriferous beach sands containing platinum and iridium of 
the Richmond-Clarence district. 
Amongst the reports contributed by Mr. G. A. Stonier, F.a.s., 
those relating to the fossiliferous rocks near Crow Mountain and 
Somerton appear particularly interesting, as the fossils as deter- 
mined by Mr. R. Etheridge and Mr. W. 8. Dun, confirm the 
previous opinion as to the extensive development in those areas 
of the Gympie beds. I should like to express my regret that my 
old colleague on the Geological Survey, last year resigned his — 
position as Geological Surveyor, with a view of further prosecuting 
his geological studies in Europe. 
Mr. J. B. Jaquet’s report on the “ Platinum Deposits of Fifield” 
show the growing importance of that branch of the mining 
industry. About 1,200 ozs. of crude platinum are estimated to 
have been raised previous to the commencement of this year.
