Specimens from Crudine, Kempsey, Bellinger, Hillgrove, Asli- Case 68. 

 ford, Trunkey, Gulgong, Carangula, and Solferino are exhibited. 

 1556, from Solferino, shows antimonite within the oxide; evidently 

 the whole mass was once antimonite.

Slionite : sulphide of antimony. By far the most common Antimonite. 

 ore. It is a greyish-black mineral, generally occurring in bundles 

 of blade-like crystals. It is very soft, and can be fused by 

 holding a splinter in a candle flame ; this easy fusibility affords a 

 ready means of identification. Antimonite is very frequently 

 crystallised — sometimes in needle-like crystals of great delicacy 

 (see 962 and others from Carangula) : flat forms with transverse 

 striations, like 966 and others from Hillgrove, are also common 

 and characteristic. 



Although nothing comparable to the unique antimonite crystals 

 from Japan (see special case facing the entrance) have been 

 found, yet some of the specimens exhibited are very beautiful. 

 9564, Hillgrove, and 6915, Pretty Gully, New England, show a 

 crust of oxide eating into the sulphide. 2844, Bowra, illustrates 

 the granular form often assumed by the mineral when not 

 distinctly crystallised. Antimonite is sometimes associated with 

 gold ores, or may even be itself auriferous ; this is particularly 

 the case at Hillgrove. This association with gold is well illus- 

 trated in the gold cases. (See pages 31 and 33.) 985, Brereton's 

 property, Hillgrove, showing free gold, is exhibited here. 



Fahlore: sulphide of copper and antimony. This mineral is paMerz. 

 placed here for convenience ; it would more appropriately be 

 arranged with the ores of copper. Fahlerz does occur crystallised, 

 but there are no specimens from New South Wales in the collec- 

 tion. The ore is f I'equently argentiferous. The identification of
