Swan Island, Bass Straits. (Gould, Pro. Royal Soc. Tas., 1871.) 
3. ALLOPHANE (Hydrated Silicate of Aluminum). 
The examples are of interesting colouration, which is yellow to 
brown in water, but blue when exposed. It is somewhat opaque. 
Occurs in serpentine as a narrow vein from a few inches to above 
one foot in width. 
Harman’s Rivulet, under the Parson’s Hood (W. R. Bell); 
near Derby, as a band of a pale waxy-yellow colour. 
4, ALIPITE (a Silicate containing Nickel Oxide). 
Of extremely rare occurrence in small amorphous masses at 
the Heazlewood Silver-Lead Mine. In colour it is a pale apple- 
eveen with a dull lustre. It has also been obtained at the Bell’s 
Reward and Godkin mines in limited quantity. 
5. ACTINOLITE (a green-coloured fibrous variety of Horn- 
blende). 
The radiating variety occurs a few miles south of the Hamp- 
shire Hills, up the Emu River. It is found associated with an 
iron garnet, amethystine quartz, and fibrous radiating iron, which 
is probably limonite. At the Heazlewood it is plentiful in spread- 
ing and radiating acicular bunches of considerable size and greenish 
colouration. Obtained in large masses on the River Forth, about 
three miles from Mt. Claude. Onthe Whyte River, near the base 
of the Meredith Range, this mineral occurs of a dark asparagus- 
green colour—much resembling the variety termed Calamite— 
containing minute bunches of Asbestos and particles of Mountain- 
cork, the whole closely intermixed with bands of a yellowish-brown 
garnet rock which often contains Molybdenite. The Mountain- 
cork is of a spongy and closely interlaced structure, pale brown 
to brownish-green in colour, and is often much stained with iron 
oxide. 
6. ARSENOPYRITE (Mispichel). 
Widely distributed, occurring chiefly in lodes in crystalline rocks 
with various other forms of pyrites. It is very abundant through- 
out the north-eastern portion of the island, and occasionally 
contains a small quantity of silver. In the vicinity of the 
Scamander River it commonly occurs, sometimes in large masses. 
At Mt. Sorell, on the West Coast, it is abundant in the form of 
minute but extremely well-formed free crystals in river drift, the 
crystals showing many beautiful modifications and mackles; at 
Waterhouse it has been mixed in dense compact masses contain- 
ing gold in a quartz matrix; at Mt. Ramsay it occurs with other 
pyrites and native Bismuth in Amphibole—assays of the
