PAPERS, 
An interesting paper entitled, ‘‘ Contributory information regarding 
the tin ore deposits at Mount Bischoff, Tasmania,” by Baron Von 
Groddeck, chief mining councillor of the Hartz mining districts, and 
director of the Royal] Prussian Academy of Mines at Clausthal, Germany, 
was read by the Curator, in the absence of the translator, Mr. Thureau, 
who had telegraphed to say that he was unavoidably detained in the 
country, and so was prevented from attending the meeting of the 
Society. In a letter from Mr. G. Thureau, F.G.S., to the Royal 
Society, he stated that the above paper had been published in the 
journal of the German Geological Society, of 1884. It was a subject 
he (Mr. Thureau) thought would be of great interest to the Fellows 
of the Society, so he had, therefore, translated Mr. Groddeck’s 
paper. The Baron states that the Royal Academy of Mines at 
Clausthal was some time ago placed in possession of a very fine 
collection of Australian ores, the collection being presented to 
the Academy by Mr. M. Wajenknecht, a resident of Tasmania. 
Amongst the samples were found a,number of specimens of tin 
ore, together with the rocks and the minerals said to be associated 
with same from Mount Bischoff. The Baron says the series particularly 
interested him on account of a piece of supposed quartz-porphyry, which 
rock, it was represented, is associated (according to the description 
of Mr. S. H. Wintle and Mr. Geo. H. F. Ulrich) with those tin 
ores, and also because of some peculiar, dense, greyish-blue coloured 
masses of mineral which most frequently are found to enclose those tin 
ores. The Baron gives a very careful analysis that he made of the 
specimens he had received. 
Mr. C. P. SprentT said the paper was a most interesting con- 
tribution, but it raised so many unexpected new points that it 
would require very careful study before the Fellows could discuss it. 
He would have liked to have seen some of the specimens which were
