CRYSTALLIZED STANNITE 



A small consignment direct from the silver mines in Bolivia affords new 

 and unique examples of the following. They have been identified by high 

 mineralogical authority. 



Stannite, Splendent crystals, grouped in cavities of the massive 

 mineral. The crystals are most perfectly developed and very rich in planes. 

 The species has been known to science for over a century, but until recently 

 only in the massive form, thus leaving its crystallographic form in question. 

 Hence the present find is peculiarly welcome. 



Andorite. A silver and lead sulph-antimonide. Massive and in small 

 but characteristic crystals of highly modified orthorhombic habit. Some- 

 times associated with the crystallized Stannite.
