ALCOHOL 



Its Manufacture 

 Its Denaturlzation 

 Its Industrial Use 



The Cost of Manufacturing Denaturized Alcohol in Germany and 

 German 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. Diederichs in Scientific American Supple- 

 ment 1596. Many clear diagrams 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 a 

 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 published 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 Amer- 

 ican Supplements 1603, 1604 and 1605. The article is by L. Baudry de 

 Saunter, 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 Revenue will permit 

 the manufacture and denaturization of tax-free alcohol.

Floors warm 

 as the Seashore 



What can be nicer for our little pets 

 (and their little pets) than a cheerful, 

 sunlit bedroom, tempered genially 

 and uniformly by 



American x Ideal 



t\ Radiators ^Mboilers 



Children have better health where they can freely 

 play and exercise instead of being confined to 

 the limited playground afforded by the heat of 

 a stove, grate fire or hot air furnace register. 

 You can dress them lightly and let them play 

 safely where they will on the floors, in the 

 corners, at the windows or in the hallways — 

 when the house is warmed by Steam or Water. 

 The floors are thus made warm as a sandy 

 beach on a fair August day. 



An outfit of IDEAL Boilers and AMERICAN Radiators costs 

 so little more to put in that the coal savings of a few Winters 

 will more than pay the difference — and the economies will 

 thereafter equal large dividends on the investment. OLD 

 buildings — farm or city — are easily fitted out without annoy- 

 ance to the occupants or removing old heating methods until 

 ready to start fire in the new. Ask for valuable catalogue —
