which case it is proportionally more or less striated in structure ; 
some samples from the Heazlewood district show this in a marked 
degree. Asaruleitis comparatively pure and free from deleterious 
admixture, zine in particular—the bane of the metallurgist — being 
of exceptional occurrence in large quantity. Many specimens 
from the Junction and Queen mines at Zeehan are highly iridescent 
and show a beautiful play of colouration in blue, green, and red. 
At the Sylvester mine a large quantity of beautiful dark green 
Pyromorphite and fairly. well crystallized Cerussite has been 
obtained, overcapping the primary ore; and one of the lodes on 
the Queen property contained a considerable amount of Lithomarge, 
more or less impregnated with Silver chlorides, in the surface 
levels. That from the Owen Meredith mine had in many instances 
very fine masses of arborescent Native Silver in the clefts of the 
ore body, with which an Antimonial Silver mineral was also 
associated. 
At the Maestrie’s Broken Hill mine at Dundas an extensive 
body of oxidised argentiferous lead ore has been worked, over- 
capping and interspersed throughout the original mineral. The 
ferro-manganese lode capping of the Adelaide Proprietary mine 
at the same locality has become somewhat celebrated for the 
wonderfully fine bunches and masses of Crocoicite that have been 
obtained; in some of the more solid portions of the surface outcrop 
the gradual transmutation of the Lead Sulphide to the Chromate 
can be distinctly traced, and the vughs often contain remarkably 
developed crystals of the latteras acoating. TheScamander Silver- 
lead mine consists of a mixture of several silver-bearng minerals, 
the more important of which are Pyrites—principally arsenical, 
Sphalerite, and Galena. At the Rex Hill mine in the Ben Lomond 
district the somewhat peculiar association of Cassiterite, Mariatite, 
Chalcopyrite, and Galena is a noticeable feature in a portion of 
the property. In addition to the minerals mentioned, small lumps 
of green Malachite are occasionally met with in trenches on the 
surface. At the Madame Melba at Dundas, and Silver Cliff at 
Bischoff, Galenite is commonly met with in conjunction with 
Jamiesonite and mixed oxides, resulting from the decomposition 
of the two minerals. 
On the south bank of the Mackintosh River, about forty miles 
south-east of Bischoff, a large body of Galena has been discovered, 
much of which is intermixed with a cleavable Calcite and 
amorphous Siderite. It occurs near Deloraine with Baryta and 
Dolomite, sometimes showing alternate bands of Galena and 
Sphalerite. In the gold mining districts of Beaconsfield, Lefroy, 
and Mathinna, it is found in the reefs, often to considerable depth, 
in limited quantity, generally intermixed with Pyrites. At the 
Hampshire Hills an argentiferous lode was worked upon by 
the Van Diemen’s Land Company some years back, but without 
any permanent practical results. The matrix of this discovery
