Sell eelite. ='■ — Blackburn . 



A massive specimen of calcium tungstate in rolled nodules ; contains a 



little quartz. 



Scheelite. — Lake Wakatipu. 



Very much the same as the last. 



Galena. — Tokomairko. 

 This is the common ore of lead, a compound of lead and sulphur ; 

 associated with quartz. 



Presented by Mr. Gillies. 



Galena, f — Wangapeka. 



Eolled nodule of quartz, containing veins of galena. 



Galena. — Nelson. 

 Associated "with quartz. 



Mafjnetite. \ — Dunstan. 



A rolled nodule of the magnetic oxide of iron (Feg 0^), containing 



quartz. 



Magnetite. — Maori Point, Shotover. 



Massive, with a granular structure. Stained with green carbonate of 



copper. 



Magnetic Iron Sand. — Awamoko Creek, Marawhenua Goldfield. 



The specimen consists principally of rolled grains of magnetite and of 



titaniferous iron ; associated with them are a few zircons (hyacinth), a httle 



gold, brown hematite, a little quartz sand, and pieces of iron from tools. 



Magnetite. — Nelson. 



Massive, impure ; stained in places with green carbonate of copper. 



Associated with it is a compound silicate of iron, lime, magnesia, potash, 



and soda. 



Specular Hematite. — Longwood Mountains. 



In small lamellar and granular masses, embedded in quartz. 



Red Hematite. — D'Urville Island. 

 Massive ; of very good quahty. 



Red Hematite. — Horseshoe Bush. 

 A botryoidal concredon of sand, cemented together by red oxide of iron. 



Brown Hematite, — Dunstan. 

 A hoUow nodule of the variety of u'on ore known as limonite. Of 

 very good quality ; when fairly pure this ore contains some 55 per cent, of 

 metallic h-on ; the red variety of hematite may contain as much as 70 per 

 cent. ; and magnetite, which is the richest, may yield 72 per cent, of iron.
