11. ALUNOGEN (Sulphate of Alumina). 
Often abundant as an effloresced incrustation in caverns occur- 
ring in argillaceous rocks. 
Occurs near Bridgewater; Brown’s River Road; near St. 
Mary’s; Mersey River, about four miles from Chudleigh, known 
locally as the Alum Cliff; Blue Tier, near Beaconsfield. 
12. AXINITE (Silicate of Alumina and Lime. with Boracic 
Acid, &c.) 
This rare mineral was detected by Professor Ulrich during his 
examination of the Bismuth and Gold discovery at Mount 
Ramsay. It occurs in thin brown patches or blebs in the 
Amphibole rock, and is comparatively rare. It has not been 
discovered in Australia. 
13. ATACAMITE (Oxychloride of Copper). 
The beautiful green ore of Copper is occasionally met with in 
radiating acicular bunches in the vughs of ferro-manganese 
gossan ore capping the lode on the property of the Comet S.M. 
Co., Dundas; in small quantity in mixed oxidised ore, Silver 
ae Zeehan; in vughs, Gad’s Hill Range, Upper Mersey 
iver. 
14. ANDALUSITE (Anhydrous Silicate of Alumina). 
Abundant in slightly elevated radiating masses of a light 
colour near the Lottah mine, Blue Tier. 
The variety Chiastolite occurs sparingly at Zeehan in Silurian 
slate-rock as radiating and interlaced prisms of small size. 
15. AZURITE (Blue Carbonate of Copper). 
This beautiful mineral is only known to occur in this island as 
thin scaly masses, and as extremely minute crystals. 
Hampshire Hills; Gad’s Hill; Dundas; Zeehan; Main- 
waring Inlet; Mackintosh River; Penguin; Saxon’s Creek ; 
Cascade ; Heazlewood, and other places. 
16. ANATASE (Titanic Acid). 
Occasionally obtained with its chemical congeners Rutile and 
Brookite. It is usually very much waterworn, but occasionally 
fairly good examples may be found. 
Clayton Rivulet; near the River Forth ; near Mount Lyell ; 
in the streams in the vicinity of Brown’s Plain. 
17, ALMANDITE (Alumina-iron Garnet). 
In small crystals, which are translucent and of fair colouration, 
near Mount Heemskirk.
