 color with adamantine luster. The locality is the Broken Hill 

 silver mines of New South Wales. It is named after Prof. 

 Henry A. Miers of Oxford. — Nature, April 14. 



Kalgooelite is a telluride of gold, silver and mercury described 

 by E. F. Pittman from the telluride deposits of Kalgoorlie, West 

 Australia. It occurs in massive form with subconchoidal fracture 

 and iron-black color; specific gravity S'T^l. An analysis by J. 

 C. H. Mingaye gave the following results : 



Te S Au Ag Hg Cu 



[37-26] 0-13 20-12 30 98 10-86 0-05 = 100 



For this the formula HgAu 2 Ag 6 Fe 6 is calculated. Associated 

 with kalgoorlite is a yellow telluride of gold (Te 56'65, Au 41*76, 

 A or 0'80) with sp. gravity = 9*377. This is referred to calaverite.
