ANTIMONY. 
This metal has been found in New Zealand in the form of Stibnite, 
which mineral has a pretty wide distribution, and is associated with Kermes 
and Cervanite, as products of decomposition or change. It has also been 
found as Bournonite (a mineral which more properly belongs to the lead ores), 
in the Rolling River, Wangapeka, and again as a constituent of Richmondite, 
a form of Tetrahedrite, which occurs at the Richmond Hill Mine, Collingwood. 
Stibnite, Sb.—The first mention of the occurrence of this mineral | 
in New Zealand is by Dr. Hector (Jurors’ Rep. N.Z. Ex., p. 265). 
The specimen was from the Arrow River, and was exhibited in the 
Otago geological survey collection at the Dunedin Exhibition. In 1867, 
Captain Hutton in his report on Thames goldfield, p. 9, published in 
the Geological Reports for that year, mentions the occurrence of crystals of 
Stibnite more than an inch long imbedded in tufa in one of the claims up 
the Waiotahi Creek, and Professor Liversidge (Trans. N.Z. Inst. vol. x., 
P. 502) describes » specimen of the same mineral from the Union Jack 
Reef, Mullocky Gully. Besides these, specimens of Stibnite have been for- 
warded to the Museum from time to time from Coromandel; Kaueranga; 
Napier; Queen Charlotte Sound; Criterion Claim, Thames; Tararu Creek; 
Greymouth; Pakaraka, Bay of Islands; Green Island, Otago ; Shield’s 
Reef, Reefton; Kelly’s Reef; Canoe Creek; Collingwood; Inangahua ; 
Westport ; Pelocas Sound; Marlborough; Hokitika; Paparoa Range, 
Greymouth; Langdon’s Reef, Greymouth; Dunedin; and Featherston ; 
some by officers of the Geological Survey, and others by contributors whose 
names will be found in the Colonial Museum and Laboratory Reports. In 
describing the modes of occurrence of Stibnite, a natural subdivision presents 
itself between the crystalline and massive varieties. 
Crystallized varieties.—We have specimens in the Colonial Museum of 
Some fine interlacing erystals of Stibnite from Tararu Creek, where they 
Kaueranga (Shortland), there is a very fine specimen of crystallized 
Stibnite, in which the erystals interlace in a most.characteristic manner. 
From the Golden Crown Claim, Thames, there is a group of crystals 
of large size, the longest one measuring about 4 inches along its prin- 
cipal axis. The only forms of crystals which are represented from any 
of these localities are prismatic, consisting of the rhombie prism oP. 
and the brachy-pinacoid, oPo; with pyramidal ends composed of the 
Pyramid P. and several brachy-pyramids, mPn, which give the ends a 
Tounded appearance and are not sufficiently defined for measurement. All
