var. Ruby Spinel. — Both determinations of this mineral are 

 wrong, and, to my knowledge, it has never been identi- 

 fied in Victoria (U.). 



var. Pleonaste. — This common black variety occurs in many 

 of our alluvial deposits, and is frequently mistaken for 

 cassiterite. It can easily be distinguished by its 

 vitreous lustre, conchoidal fracture and superior 

 hardness. 

 Stibnite. — Antimony sulphide. 



United Brothers' Mine and Democratic Mine, Glen Wills 

 (CI.). 



Scrubby Creek, Mitta Mitta ; Mulgrave ; Eildon, Goulburn 

 River ; with antimony oxide, Burgoyne ; with kerme- 

 site, Tallandoon ; Toombullup ; Little River, Wodonga ; 

 Steel's Creek ; a vein two to three inches wide, the 

 casing shows gold, one mile east of DunoUy (M.Dt.); 

 with antimony oxide, 14 miles from Euroa (W.). 

 Stilbite. — Hydrous silicate of aluminium, calcium and sodium. 



Small sheaf -like groups of clear crystals from druses in 

 the older basalt, Westernport (W.). Small crystals 

 associated with calcite from a joint in mesozoic sand- 

 stone, San Remo (R.). 

 Taenite. — A meteoric nickel-iron. 



On decomposition and disintegration taenite lamellae may 

 be separated in quantity from the resulting fine material. 

 The highest specific gravity obtained was 7"1754 which 

 is low for an alloy so rich in nickel. Analysis : 



No. 2, after deducting the phosphor-iron-nickel (3-73%). 

 Beaconsfield meteorite (C). In addition to taenite 

 other nickel-iron alloys are common to metallic meteor- 

 ites such as plessite and kamacite. Although only one
