    6. Alloys^.—Prepare alloys of antimony, and note their properties. 7. Chemical Action.—Note the action of water, HCl, HNOg, H2^04, and NaOH on the metal. Bismuth 1. Sjjccijic Gi'avity.—Determine the sp. gr. of bismuth. 2. Brittleness.—Note that it is a brittle metal. 3. Fusion.—Note its low melting point. 4. Expansion on Cooling.—Cast an ingot, and note that it expands on cooling. A valuable property of the metal. 5. Amalgamation.—Shake powdered bismuth and mercury in a bottle, and note the liquid character of the amalgam. 6. Alloys.—Prepare alloys of bismuth. 7. Oxidation.—Note that the metal oxidises before the blowpipe. 8. Chemical Action.—Note the action of H,S water, HCl, HNOg, H2SO4, and NaOH (solution) on the metal. Aluminium 1. Specific Gravity.—Determine the sp. gr. of aluminium, and note its low density. 2. Malleability.—Poll the metal to prove its malleability. 3. Chemical Action.—Note the action of HoS water, HCl, HNOg, H2SO4, NaOH, and NagCOg on the metal. 4. Alloys.—Prepare alloys of aluminium. Mof/ncsium 1. Specific Gravity.—Determine the sp. gr. of the metal. 2. Oxidation.—Note that the metal oxidise^?, and produces a bright light when it burns. 3. Alloys.—Prepare alloys of the metal.
