mainly to the preparation of alloys witli tin and lead, that have Case 70, 

 the properties of fusing at a low temperature and of expanding 

 on solidification, and to medicinal purposes. The organisation of 

 the bismuth trade prevents the exportation of more than a limited 

 number of tons of ore annually. 



This mineral has a very characteristic appearance, by which it Native 

 may be readily recognised with a little experience. A ruddy 

 tinge is often displayed — well shown in the Cobar specimen. It 

 has been found in several localities, but principally on the granite 

 tableland of New England. 



Kingsgate, near Glen Innes, yields the greatest quantity of 

 native bismuth, where it is accompanied by molybdenite (see 

 page 87). Numerous specimens of the Kingsgate ore are 

 exhibited here, but the best are in the New South Wales 

 Court of the Imperial Institute, in London, 



9077, Kingsgate : shows good cleavage faces with a highly- 

 metallic lustre. 



1011, Kingsgate: a massive lump of native bismuth with a 

 little quartz ; the cleavage faces are coated with carbonate of 



bismuth. 



1012, 1014, Kingsgate : show acicular crystals of native bismutb 

 traversing glassy quartz. 



7786, Jingera, Whipstick : granite with native and sulphide of 

 bismuth. 



6759, Jingera : somewhat similar to 7786, but containing mucb 

 molybdenite, the bluish plumbago-like mineral. This ore assays 

 lOf per cent, of bismuth and 6^ dwt. of gold per ton. 



Further specimens of the Jingera ore, which is sometimes rich 

 in silver, will be found under Silver 60 (see page 53). 



9173, in case 96, Kingsgate: rock crystal, with acicular native- 

 bismuth. 



1010, Kingsgate : quartz, showing native bismuth and 

 molybdenite very clearly.
