NICKEL.
This metal has been found on the West Coast, I think. It is largely used in nickelplating, and for some varieties of brass. Its ores are generally heavy. Chloanthite is an arsenide of nickel, containing about 28 per cent, of metal, the rest being arsenic. Nickeline is also an arsenide, but contains 44 per cent, of metal. Millerite, a sulphide, is a mineral of a brass yellow colour, and contains 64 per cent, of nickel. There is also a silicate and a carbonate. All the above ores give the metallic powder which is attracted by the magnet. The borax bead in the oxidising flame is violet or reddish brown, according to the quantity of powder added. In the reducing flame the bead becomes grey, and after a second or two colourless. (Distinction from iron, which becomes dirty green.)
