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 

 of Gas in all its uses. Town Gas for Power Generation, including 

 Private Electricity Supply. The Legal Relations of Gas Sup- 

 pliers, Consumers, and the Public. Index. 



The " country," as opposed to the " town," has been denned 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
