thread. Prom Stockyard Reef, Whroo. (Attached to the Antimony Ore is some of the bounding rock of the vein). 3G5 Ferruginous Antimony Ochre. Upon assay it gave 31 ‘8 per cent, of antimony. It was got from the foot wall of the lode in the 60 feet level at llingwood, near Melbourne
366 Antimony and Iron Ores in Quartz. The greater part of the
Antimony is in the crystalline parts of the specimen and in the joints. From a reef which contains gold. The specimen was got from 87 feet in depth in a cross reef at the Antimony Mines of Ringwood. The lode was 18 inches in thickness
Zinc.
367 Blende (Sulphide of Zinc), with small crystals of Iron
Pyrites. An assay for silver yielded results equal to 3 ozs. 5 dwts. of silver per ton. From the 400 feet level in the Western Reef, Chrysolite Ilill, St. Arnaud. This Reef is 4 feet in width
Lead.

from 3 feet to 3 feet 6 inches in width, and is well defined. Its strike is N. 35 deg. W., and its dip about 63 deg. S.W. An analysis of a sample of ore from this vein gave—Lead, 20 per cent.; iron, 30 per cent.; sulphur, 41 per cent.; zinc, 3 per cent., &c.
Cobalt.
