and ENHYDROS.

The minerals mentioned in the following short note form part of 
a collection recently purchased by the Trustees of the Australian 
Museum ; some of them are of unusual interest, hence it was 
considered desirable to draw attention to them in the pages of the 
“ Museum Records.” The numerals simply indicate the different 
specimens examined and described, those which are of the ordinary 
character and from well known localities are not mentioned in 
this paper. 
Native Bismuth. 
1. Some of the bismuth is in the massive condition, and is 
similar to specimens already described in the “Journal of the Royal 
Society of New South Wales,” 1891, other specimens show it in 
the form of acicular crystals running through rock crystal. The 
massive bismuth is associated with quartz, both crystallised and 
massive, sulphide of bismuth, bismuth ochre, galena, the latter 
argentiferous, iron pyrites passing into ferrous sulphate, wolfram, 
molybdenite and tin stone. From Kingsgate, Glen Innes, N.S.W. 
2. The acicular crystals in one case are two to three inches 
long and of about the thickness of a horse hair, these completely 
penetrate the rock crystal in much the same way as we often see 
acicular fibres of rutile ; the characteristic colour, metallic lustre 
and cleavage of the metal being, however, well shown. This 
appears to be an unusual mode of occurrence for bismuth. 
Kingsgate. 
3. Accompanying the fibres of the metal are small scattered 
crystals or specks of the metal, together with small columnar 
crystals. Kingsgate. 
4. Native bismuth in quartz from Tingha, N.S.W. 
5. Native bismuth, from Kangaroo Hills, Queensland. Asso- 
ciated with chlorite, quartz, and red oxide of iron or gossan.
