purpose of purification. The process is not considered complete 
until the metallic antimony forms, in cooling, beautiful star-like 
crystallizations on the surface ; it is then known as star antimony. 
This metal is used in the manufacture of type metal, stereotype 
metal, music plate, Britannia metal, pewter, &c. ; also for medical 
purposes ; and is capable of forming excellent paints and pigments, 
a fact worthy of consideration in connection with the antimony 
ores found in this colony.

Sulphate of Barytes, T. — Anton Mine, Baden. 
105. Stibnite. — Sulphide of Antimony^ T. — Felso-banta.

of Molybdenum, T. — St. Gotiiard. — Is sometimes mistaken for 
black lead, but, being laminated, differs from that mineral. 
This is very evident on careful examination. Plumbago, or black 
lead, leaves a black streak on porcelain ; Molybdenite, a distinctly 
yellowish-green streak,

times also in octahedrons.
