 is the first I have seen in which the crystals have chstu.et ternnnatu.ns 

 The hand specimen consists of an aj^gregate of pr.sn.at.c crysta s groupe.l 

 paHly i" parallel or slightly divergent positions, several w.th ter.n ,.- 

 Sons • some of the crystals are bent and distorted as .s so commonly the 

 case with stibnite, and in part the mineral is massive or imperfectly 

 orvst Jlised Most of the crystals are slender, bat a few are fairly stout, 

 ::i i " neaHy 1 cm. in thickness. 'H.e lustre is brilliant, resembling 



raToTpolished^steel. A few small crystals of quartz are attached to 

 the stibnite. 



The measured crystal is short prismatic in habit, about 3 mnu in 

 lenc^th and 1 mm. thick, and bent sharply not far from the terminated end.

 Although the wolframite mined in New South Wales is generally 

 massive crystals are not uncommon, particularly in the lo.nngton
