    PREFACE The Preliminary Observations, with which this volume commences, comprise some brief considerations on the fundamental doctrines of chem- istry, most of which may be included in an account of the general laws which govern, and the phenomena and changes which accompany, the chemical combination of different bodies. This introduction concludes with an explanation of Chemical Symbols, and a table of Equivalents. The article on Gas Illumination comprises not only a detailed account of the process of making light-gas from coal, and of the chemical and physical properties of the constituents of coal-gas, but several important collateral subjects ; among which are some considerations on the modes of burning gas and on the economy of gas illumination, descriptions of the process for making light-gas from other sources than coal, and an account of the applications which the secondary products of the coal-gas manufacture have received. The construction of different kinds of regu- lators and meters, and the process of naphthalizing gas, are also con- sidered. In the article on the Preservation of Wood, which follows that on Gas Illumination, means are pointed out for effectually guarding against the ordinary decomposing influences of air and water on timber. A consid- erable portion of the article is devoted to an account of the important ex- periments of Mr. W. Hyett, on the effects of the impregnation of wood with foreign substances. Dyeing and Calico-printing forms the comprehensive subject of the concluding article of the present volume. Most of the leading processes now practised by the calico-printers of this country are there described, accompanied with explanations of the scientific principles on which they are based. Several of these processes, new to treatises on the subject, will be found of considerable value.
