discovered in Australasia occurred in some quantity at the 
Maestrie’s Broken Hill Silver-Lead Mine at Dundas. Many of 
the crystals obtained at this mine are large and_ beautifully 
developed, occurring in masses of considerable size, sometimes 
containing Massicot in the interstices and as a base. Commonly 
large lumps of Galena are coated with Anglesite, Cerussite, and 
Masscot, presenting an appearance that has become fairly 
characteristic of this mine and the Comet adjoining. This 
mineral has also been sparingly found at the Whyte River, 
and at Zeehan. It crystallisesin rhombic prisms with pyramidal 
terminations. This mineral often gives high assay returns in 
silver, which is held in the form of one or either of the Chloride 
group. Mr. W. F. Ward states (Tasmanian Official Record, 
1892), “ Anglesite with Oxide of Iron and Manganese, and yield- 
ing up to 480 ozs. of Silver per ton, has been discovered.” 
23. ARRAGONITE (Hard Carbonate of Calcium). 
Often found in cavities of basalt as radiating and bunching 
masses at Lefroy ; Mount Bischoff; Sheffield and Springfield. 
It is stated to occur at Bridgewater and West Tamar ; Chudleigh, 
where it forms stalactites, in the limestone caves of the locality. 
24. ARSENIC, NATIVE. 
In hemihedral crystallizations with radiated internal structure, 
colour almost tin-white, tarnishing black. 
East Bischoff mine; in lowest level North Valley lode, 
Bischoff, in blades between lamin of Siderite with Fluorite, 
various Pyrites and Black Sphalerite. 
25. ARSENOLITE (Arsenious Acid or White Arsenic). 
A single large lump was obtained at the Devon Consols mine 
at the Penguin, associated with Arsenical Copper, Melaconite, 
and a little Native Copper. 
26. ASPHALTUM (Bitumen or Mineral Pitch). 
About four miles from Chudleigh on each bank of the Mersey 
River. It is perfectly black, sectile, burns with a dense smoke 
and strong odour. It occurs in a drab-coloured aluminous shale. 
“ A species of, occurs on the north end of Prime Seal Island”’ 
(Gould, Pro. Royal Soc. Tas., 1871, page 61). 
27. APLOME (Ivon-lime Garnet). 
A Garnet, of various shades of brown, but generally of a 
cinnamon colour. They occur in great abundance and large size, 
often reaching above an inch in diameter. When first broken 
out they are very fine and beautiful. 
Hampshire Hills and on the banks of the Upper Emu River.
