In No. 2 (c), 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 washing. _ 
Kermes ( Antimony Blende), 3’, Sb,—This mineral occurs generally 
with the Stibnites, as a cherry-red encrusting earth on exposed parts 
of the specimen. 
Cervantite, Sb, Sb. Gocurs incrusting Stibnites at most localities. 
TrtuuRIuM 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 Rich- 
mondite of Colliigwood, 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. 
Meratiic Mrverats.—Class III. 
Malleable, not reducible by heat alone. 
Zinc. 
This metal is met with in New Zealand, chiefly as the ishusle ie a 
Blende, but in one instance the mineral Calamine, or carbonate of zine, has 
been obtained. 
Zinc Blende, Zn’.—The first mention of the cecurenes of this mineral 
in New Zealand is by Dr. Heetor (Trans. N.Z. Inst., vol. i., p. 368) wh 
tefers to its occurrence on the Thames goldfield, associated with gold in :
