Abstract
THIS volume attempts a presentation of very much more than its title would lead one to infer; it sprawls over the manufacturing, distributive, and legislative aspects of towns' gas. Contrary to the author's expressed intention, the mechanical and not the chemical aspect of gas manufacture receives the greater prominence in the work. Thus, whilst eighteen pages are devoted to the chemistry of high and low temperature carbonisation, and eight to the chemistry of water-gas production, we find one hundred pages devoted to the description of carbonising plant, et hoc genus omne. Other chemical subjects discussed in the work include the gas laws, the constituents of coal gas, the materials of coal gas manufacture, residuals and analytical methods, whilst sections predominantly mechanical are devoted to condensation, gas purifica tion, washing and storage, labour-saving appliances. Pyrometry and refractories are treated in a very inadequate five pages.
