Book excerpt: Excerpt from Chemical Technology, Vol. 4: Or Chemistry in Its Applications to Arts and Manufactures, With Which Is Incorporated Richardson and Watt's Chemical Technology Some apology is perhaps necessary for the attempt to compress into the space of some two hundred and seventy pages a mass of information covering the whole subject of Electric Lighting. The aim has been to put together a connected, and, as far as possible, complete and scientific account of the whole subject in such a manner as it is hoped may be useful to specialists in one or more branches of work connected with electrical industry who may wish for a risfimi of all the various systems, machinery, lamps, kc., in use for the supply of electric lighting; more especially to Architects, Civil and Mechanical Engineers, and scientific workers, to whom a general knowledge of the subject is of professional value. To such readers the completeness of their general view is of the highest value, though it may not be the detailed knowledge of the actual worker in one branch, since they will wish to know the reasons, not merely the bare facts, of certain data and limitations which, originating in the achievements of a collateral industry, may apply to their own professional work. It is hoped that the work may be read with facility by any one who has an elementary knowledge of Electricity and Magnetism, or even that knowledge which every educated person will acquire by observation without further instruction and reading. Efforts have been made to avoid gaps in the logical continuity of the argument; and to simplify formula by a reduction to the minimum of all minor corrections necessary to professional exactness. In short, the aim is a readable treatise, as well as a work of reference. Details which are likely to be ephemeral only appear as examples; and the examples of manufacture chosen for description, or theory of design, are not necessarily those believed to be the most recent or the best, but such as are thought serviceable for expounding the principles and methods of manufacture and working. The section relating to photometry has been carefully compiled with a view to the full description of existing and proposed standard methods of determining the visional intensity of artificial illumination, and particularly with a view to showing the necessity for an International Agreement as to a standard of light.
