 In No. 2 (cj, the gold was visible in the stone, running as a thin vein 

 through the centre of the specimen, and, a large proportion being free, it 

 can readily be separated by Avashing. 



Kermes f Antimony Blende), ^'"^ Sfe. — This mineral occurs generally 

 with the Stibnites, as a cherry-red encrusting earth on exposed parts 

 of the specimen. 



Cervantite, Sh, -Sfe. — Occurs incrusting Stibnites at most localities. 

 Tellurium and Bismuth. 



The other members of this group have never yet been discovered in 

 .New Zealand, with the exception of traces of the latter metal in the Kich- 

 mondite of Collingwood, but the striking resemblance of some of the rocks 

 of that district, and the occurrence of associated minerals which are com- 

 mon with the Bismuth ores of Beaver County Utah, make it by no means 

 improbable that we shall yet have to add that valuable metal to the list of 

 those which occur in New Zealand. 



Metallic Mineeals. — Class III. 



Malleable, not reducible by heat alone. 



Zinc. 



This metal is met with in New Zealand, chiefly as the sulphide or Zinc 

 Blende, but in one instance the mineral Calamine, or carbonate of zinc, has 

 been obtained. 



Zinc Blende, Tin'. — The first mention of the occurrence of this mineral 

 in New Zealand is by Dr. Hector (Trans. N.Z. Inst., vol. ii., p. 368) where he 

 refers to its occurrence on the Thames goldfield, associated with gold in 

 some of the reefs, and it was originally discovered by Captain Hutton in a 

 claim situated upon the Tararu Creek, in the Thames district, where it
