purplish-black or greenish-purple tufaceous shale, and 
contains scales of native copper from one-twentieth to 
one-quarter of an inch in longest diameter, averaging 
one-tenth and about one-fortieth thick. Their prevailing 
shape is circular, more or less. The following analysis 
was made by Mr. J. C. H. Mingaye, analyst and.

CovELLINE.—This mineral occurs with redruthite, the copper 
sub-sulphid Cu,S and other sulphur ores of copper 
at Cobar and other copper mines in New South 
Wales (L.). 
Cuprite.—Broken Hill Mines, associated with silver ores ; 
common in copper lodes of the colony ; (Geo. Sur., Dept. 
of Mines, Sydney). 
Empouite.—Barrier Ranges Silver Field !!!, New Lewis Ponds 
Silver Mine, near Orange ! !, Captain’s Flat !, Molonglo |}, 
Billagoe, Cobar District |; (Geo. Sur. , Dept. of Mines, 
Sydney), 
Eryturite. — Hydrated arseniate of cobalt obtained by 
Mr. J. A. McKillop, near Carcoar, where it 
occurs in association with cobaltine, molybdenite, &c. 
The erythrite is present in groups of silky radiating 
acicular crystals of a beautiful peach colour. Also in 
globular and uniform masses, and in incrustations 
which present a remarkable pearly pink lustre on the 
freshly fractured surfaces. It is clearly an oxidation 
product of the cobaltine which accompanies it. (L.). 
Fiuorspar.—Allah Mine, Purnamoota, with galena ; Pheasant’s 
Creek, New England ; Pye’s Creek, near Bolivia, with 
mispickel; Seaforth Mine, Severn River, near Emma- 
ville ; (Geo. Sur., Dept. of Mines, Sydney). 
GAHNITE—Zine spinel—A lavender coloured specimen was sent 
me for identification ten or twelve years ago, 
but without locality. Mr. D. A. Porter also sent me 
a specimen of this mineral from near Tenterfield for
