Town Gas and its Uses for the Production of 
Light, Heat, and Motive Power. By W. H. Y. 
Webber, C.E. With 71 Illustrations. 
List of Contents : The Nature and Properties of Town Gas. The 
History and Manufacture of Town Gas. The Bye-Products of 
Coal Gas Manufacture. Gas Lights and Lighting. Practical 
Gas Lighting. The Cost of Gas Lighting. Heating and Warm- 
ing by Gas. Cooking by Gas. The Healthfulness and Safety

The " country," as opposed to the " town," has been defined as 
" the parts beyond the gas lamps." This book provides accurate 
knowledge regarding the manufacture and supply of town gas and its 
uses for domestic and industrial purposes. Few people realize the 
extent to which this great industry can be utilized. The author has 
produced a volume which will instruct and interest the generally well 
informed but not technically instructed reader.

The subject of this volume, the branch of metallurgy which deals 
with the extraction and refining of metals by aid of electricity, is 
becoming of great importance. The author gives a brief and clear 
account of the industrial developments of electro-metallurgy, in lan- 
guage that can be understood by those whose acquaintance with either
