ITS MANUFACTURE 

 ITS DENATURIZATION 

 ITS INDUSTRIAL USE 



The Cost of Manufacturing Denatur- 

 ized Alcohol in Germany and Ger- 

 man Methods of Denaturization 



are discussed by Consul-General Frank H. 

 Mason in Scientific American Supplement 1550. 



The Use, Cost and Efficiency of 

 Alcohol as a Fuel for Gas Engines 



are ably explained by H. Diedrichs in Scientific 

 American Supplement 1596. Many clear dia- 

 grams accompany the text. The article con- 

 siders the fuel value and physical properties of 

 alcohol, and gives details of the alcohol engine 

 wherever they may be different from those of 

 gasoline or crude oil motor. 



The Production of Industrial Alcohol 

 and Its Use in Explosive Motors 



are treated at length in Scientific American 

 Supplement 1581, valuable statistics being 

 given of the cost of manufacturing alcohol 

 from farm products and using it in engines. 



French Methods of Denaturization 



constitute the subject of a good article pub- 

 lished in Scientific American Supplement 1599. 



How Industrial Alcohol is Made and 

 Used 



is told very fully and clearly in No. 3, Vol. 95, 

 of the Scientific American. 



The Most Complete Treatise on the 

 Modern Manufacture of Alcohol 



explaining thoroughly the chemical principles 

 which underlie the process, without too many 

 wearisome technical phrases, and describing 

 and illustrating all the apparatus required in 

 an alcohol plant, is published in Scientific 

 American Supplements 1603, 1604 and 1605. 

 The article is by L. Baudry de Saunier, the 

 well-known French authority. 



In Supplements 1607, 1608 and 1609 we 

 publish a digest of the rules and regulations 

 under which the United States Internal Rev- 

 enue will permit the manufacture and dena- 

 turization of tax-free alcohol.

SCIENTIFIC AMERICAN 

 or SUPPLEMENT
