Cox.—On the Mineralogy of New Zealand. 879 
springs occur (Hochstetter, New Zealand, 1868, Eng. ed., p. 401). It is 
found again as an efflorescence on the sulphur sands of lower cretaceous 
age at Waipara (Haast, Geol. Rep., 1870-71, p. 11), and at various other 
localities ; and the late Mr. E. H. Davis mentions its occurrence (Geol. 
Rep., 1870-71, p. 181) in Doran's No. 2 Reef, at Wangapeka. Analyses of 
samples from White Island have given the following results :—

They vary in physical characters from a massive rich sulphur yellow 
mineral to a loose friable variety with a pale-greenish tinge and some very 
beautiful, although small, crystals also occur. These are of a pale-greenish 
colour, and consist chiefly of sharp acicular rhombic prisms; but some very 
unusual combinations also occur which have been described by the late Mr. 
E. H. Davis (Trans. N.Z. Inst., vol. iii, p. 284). They are frequently 
associated with erystals of selenite. 
Selenium, Se.—Prof. Liversidge (Trans. N.Z. Inst., vol. x., p. 491) states 
that he obtained traces of selenium in the massive yellow variety of sulphur 
from White Island.

Glauber Salts, Na S + 10 H.—A specimen of this mineral was for- 
warded for determination by Mr. W. H. Beetham in 1874. The locality of 
its occurrence is Brancepeth, Whareama, Wellington. 
Saurs or Baryra. 
Barytes, Ba S.—This mineral was collected by Dr. Hector from Akiteo 
in 1867, and Mr. Skey mentions its occurrence (Geol. Rep. 1870-71, p. 85) 
in the auriferous reefs of the Thames. Mr. McKay collected a specimen 
from Paonui Point, near Napier, in 1874, and specimens have also been 
received from Te Arai Point, Auckland, and from near East Cape. The 
following specimens are at present in the collection of the Colonial Mu- 
seum :— 
1. Crystals of Barytes.—Crown Princess Claim, Thames. Of a pure 
white colour, the largest erystal being about half an inch long. They are 
of a tabular form, consisting of the prism co P; the brachypinacoid o»Pco 
and the basal pinacoid OP, but in some forms the brachypinacoid is re- 
placed by small faces of the brachydome Po.
