    ALUMINIUM. ALUMINIUM. Al; eq. 27-5. A silver-white metal, sonorous, and lighter than glass, having sp. g. 2o(K). Indicated by Sir Humphry Davy in 1808; made by Wohler by de- composing its chloride with Sodium in 1828, and first produced in ingots by M. Deville in 1854. It resists the action of cold concentrated Nitric and Sulphuric Acids, but is readily attacked by Hydrochloric Acid. Its oxide, being identical with Sapphire, forms an impermeable crust on the surface of the metal, and protects it from further action of the air. Its use is limited at present to jewellery, but, from its extreme lightness and tenacity, it promises to be much more extensively em- ployed if some means of soldering it together could be discovered. Neither Aluminium nor Alumina is in the British Pharmacopoeia. Alumina, however, is much used to fine turbid medicinal waters and other solutions, and is easily obtained by adding in excess a solution of Carbonate of Potash to a solution of Alum, and well washing the precipitate. Eoche alum is scarcely ever used. Fuller's Earth and Armenian Bole are aluminous earths. ALUMEN. ALUM. Sulphate o£ Alumina and Ammonia, NH4,A1 (S04)2. 12H00. Crystallized from solution in Water. In colourless transparent crystalline masses, exhibiting the faces of the regular octahedron. Solubility in Water 1 in 12 • in boiling Water, 10 in 8. Insoluble in Eectified and Proof Spirit.
