Olivine.*' — Dunedin. 

 Brown-coloured embedded grains, possessing a green shade; fragmentary

Steatite. — Nelson.

of French chalk, etc.f 



Serpentine. — Windley Creek. 



Massive ; of a dull green colour ; translucent. This is the mineral

A foliated form of serpentine, which resembles nephrite (the mineral 

 known as jade or greenstone, the pounamu of the Maoris) in some 

 respects ; it is, however, at once distinguished by its softness. 



Green in colour, and possesses a hardness of about 4. 



Marmolite^ (Steatite?). 

 Pale green folia, on serpentine, containing hypersthene ; greasy feel ; 

 hardness about 3*5 ; rather brittle. 



Chlorojml. — Presented by Captain Fraser. 



Of a yellowish -green colour ; somewhat foliated cone-in-cone structure ; 

 sectile ; soft ; easily polished, even by rubbing with the thumb ; adheres 

 slightly to tongue : when immersed in water gives off an-bubbles, and 

 becomes translucent. 



Before the blow-pipe does not decrepitate ; blackens immediately, and 



fuses with difficulty in thin edges, with slight intumescence, to a black 



glassy slag.
