deals with a variety of substances usTially 

 placed under that particular branch of 

 scientific investigation, irrespective of 

 their individual intrinsic value, in fact, 

 by far the major portion that interest the 

 geologist, the chemist, and those in search 

 of some of the most beautiful of nature's 

 treasures. So much, says the author, is 

 knovrn of the min^eralogy of this State, 

 that the flood of discovery in this particu- 

 lar field is without doubt past, and it is 

 only by the most strenuous efforts, 

 coupled with close application, that ad- 

 ditions to the minerals already known to 

 occur can be made; but needless to say, 

 as to peculiarities of occurrence and 

 chemical analysis much remains to be 

 done. The author wishes to place on re- 

 cord his grateful thanks to many friends 

 for ready aasistance as in the past, and 

 generous donations of both beautiful and 

 interesting material for this addendum, 

 as well as for facilities for collecting, and 

 opportunities for the examination of 

 many minerals in situ. To Mr. R. W. F. 

 Waller, general manager of the Magnet 

 Silver Mining Co., who Mr. Petterd says is 

 a most enthusiastic mineralogist, he is spe- 

 cially under obligation, both for colLecting 

 at his particular locality, and for assist- 

 ance in the identification by the blow-pipe 

 and other determinations. The paper 

 then gives a detailed list and description, 

 of 31 species of minerals and their locali- 

 ties. The following is a list of the mine- 

 rals dealt with by Mr. Petterd :—Albite 

 (polysilicate of aluminium and sodium), 

 Allophane (dydrate silicate of aluminium), 

 Antimony (native). Apatite (phosphate of 

 calcium) Aragonite (orthormhic carbonate 

 of calcium), Beresourite (chromate and 



carbonate of lead), Cassiterite (dioxide of 

 tin), Chalcophanite (hydrated manganese 

 and zinc protoxide), Chrysoberyl (alamin- 

 ate of beryllium), variety Alexandrite, 

 Chromiferous Mimetite (arsenate of lead 

 with chromic acid, Chromiferous Cerus- 

 site (lead carbonate with chromic acid). 

 Dolomite (carbonate of magnesium and 

 calcium), Diopside (metasi.icate of cal- 

 cium iron and manganese), Dufrenite 

 (basic ferric phosphate), Embolite (Chlor- 

 obromide of silver). Felspar (polysilicates 

 of aluminium potassium, etc.), Lanidine. 

 Galenite (sulphate of lead), Gothite (Hy- 

 drous sexquioxide of iron), Hisingerite 

 (hydrated ferric silicate^ Hornblende (bi- 

 silicates of various protoxides and per- 

 oxides), Hixtrixite (sulphide o£ bismuth 

 and antimony). Hyalite (hydrated silica), 

 Hydrocerussite (basic lead carbonate), 

 Lepidomelaine (potassium mica rich in 

 iron), Phlogopite (magnesium mica with 

 little iron), Pyrargyrite (silver sulp. 

 antimonite), Eestormelite (hydrous sili- 

 cate of aluminium and iron). Silver 

 Native, Turgite (Hydrous sesquioxid© of 

 iron), Xanthosiderite (hydrous sexquiox- 

 ide of iron). 



The East Coast. 



Mr. J. W. Beattie exhibited over 130 

 views of interesting spots on the East 

 Coast, and imparted some useful iniorma^ 

 tion regarding the early history of that 

 part of Tasmania, and the attractions it 

 now provides for holiday-makers. 



On the motion of His Exc-ellency, a 

 hearty vote of thanks was awarded MeesirB. 

 Twelvetrees, Petterd, and Beattie for 

 their papers.
