Anniversary Address. 9 



ores occur in lodes which follow the meridional strike of the Cape 

 River lodes, and are, therefore parts of one same great mineral 

 region. 



I have dwelt on these facts, not alone because I am personally 

 interested in them, but because they belong to the progress of 

 the year 1868, and cannot but be equally interesting to many 

 here present. I am well satisfied to mention that these papers, 

 which form a part of our Transactions, were sent to the Home 

 Grovernment by Sir George Bowen, before his Excellency de- 

 parted for New Zealand, with a despatch, in which he gave me 

 full credit for my exertions in favour of Queensland ; the whole 

 being transferred for publication, by the Secretary for the Colo- 

 nies, to the Royal Geographical Society. 



"Whilst on the subject of gold, I cannot omit to interpolate 

 here the mention of a valuable paper (which I saw for the first 

 time yesterday), by one of our associates, Mr. E. B. Miller, of 

 the Sydney Mint, " On the application of chlorine gas to the 

 toughening and refining of gold," which was published in the 

 Journal of the Chemical Society in December last. 



It is well known how scientifically the author has conducted 

 his work in the establishment to which he belongs, and the pre- 

 vious records of our Society contain evidence of his endeavours 

 to overcome acknowledged difficulties in the separation of gold 

 from certain combined mineral matters. He has now come for- 

 ward with a cheap and effectual process for simplifying the re- 

 fining of the precious metal. 



In this memoir which details his experiments in the process 

 now patented at home, and which appears to be very successful, 

 he does two other of our Associates, Mr. h unt and Dr. Leibius, 

 the justice of recognising " their valuable suggestions and assist- 

 ance " in reducing the new plan of refining to a workable 

 method, and for "their earnest encouragement under difficulties.'' 

 It is, pleasant to see such recognitions as these among fellow 

 labourers in the field of science, where with right-hearted men 

 there is the feeling of true brotherhood. 



The Sydney Mint has, on a former occation, added another 



name to the list of public benefactors in the person of Mr. 



Jevons, whose more recent work on Coal was one of undoubted 



merit, receiving as its due the attention of the Parliament and
