Abstract
THIS elementary class-book supplies information required for such examinations as the Board of Education principles of mining, stage i. The idea is a good one, as the principles of pure science upon which mining practice is based are apt to receive scant attention in mining classes. The author, who is chemist to an important colliery company, has, as lecturer at the Wigan Technical College, become acquainted with the needs of students, and he gives in concise form much useful information regarding the atmosphere, the laws relating to the behaviour of gases, the diffusion of gases, the composition of the atmosphere, water, carbon, fire-damp, combustion, coal dust, explosives, the composition of coals, the analysis of coal, the strata adjoining the Coal-measures, magnetism and electricity. The language is simple, and chemical symbols are sparingly used. There is, however, a want of uniformity in nomenclature that might confuse the beginner. The terms “carbonate of magnesium” (p. 96) and “magnesia carbonate” (p. 125), “iron oxide and aluminia” (p. 46) and “iron peroxide and alumina” (p. 125) are examples. The author, too, should not. have included Cumberland haematite among the ironstones, nor granite among the strata adjoining the Coal-measures.
