The Preparation of Organic Compounds 



It gives a general outline of the methods actually employed in preparing or- 

 ganic compounds and provides, not only a laboratoty guide, but a work suit- 

 able for use as a companion volume to the usual theoretical textbook. The 

 author has added new material and made some alterations. 



Second Edition. 54 Illustrations. Cloth, $3.25 Postpaid. 



By E. De Barry Barnett, B.Sc. (London) A.I.C. 



Treatise on General and Industrial 

 Inorganic Chemisty 



The delay in completion of this edition has been due partly to the war and 

 partly to the fact that the prodigious development of industrial chemistry in 

 past four years has emphasized the necessity of chemical teaching along the lines 

 of its practical applications. Treatises on theory are numerous but those on 

 technology rare, therefore, this new modern work will be doubly welcome.

 Polytechnic and at the Luigi Bocconi Commercial Institute of Milan. 



Second English Edition Translated from the Fourth Revised and Amplified
