STANSFIELD 



NEW SECOND' 

 EDITION 



The Electric Furnace Now Ready 



By ALFRED A. STANSFIELD, D.Sc. Birks Professor of 



Metallurgy in McGill University, Montreal. 415 pages, 6x9, 



155 illustrations, $4.00 (17s) net, postpaid. 



Prof. Stansfield brings down to date the important facts re- 

 lating to the theory and practice of the electric furnace. 



The first edition of his book has been a standard. Since its 

 publication in 1907, the development of the electric furnace and 

 the increase in its use have been rapid. 



The present edition is twice the size of the first — a growth 

 made necessary both by the advance in the industry and the de- 

 mand for more detailed treatment of the subject. 



It covers not only the progress but the essential, practical 

 features of design, operation and use. It is filled with valuable 

 data, drawings and practical suggestions.

Problems in Alternating Current 

 Machinery 



By WALDO V. LYON, Instructor in Electrical Engineering, 



Massachusetts Institute of Technology. 135 pages, 6x9, 



$1.50 (6/3) net, postpaid. 



A set of problems concerning the theory of the operation 

 of alternating current machinery. There are 500 in aU, grouped 

 in seven sections, and arranged logically and in the approximate 

 order of their diflSculty. The usefulness of the book among 

 classes of students is increased by the large variety, ranging from 

 the very simple to those of considerable difficulty.

Electrical Engineering Problems 



Part I. Diiect Current Circuits and Apparatus. 

 Part II. Alternating Current Circuits and Apparatus. 



By F. C. CALDWELL, Professor of Electrical Engineering 



at the Ohio State University. 105 pages, 6x9, Si .00 (4/2) 



net, postpaid. 



A collection of 612 class-room problems, classified in 30 

 groups, for college courses in direct and alternating current 

 circuits and apparatus. A novel feature is the statement of time 

 needed to perform the actual solving of each problem. It is 

 suitable for use with any of the available textbooks or with a 

 lecture course.

Quantitative Analysis 



By EDWARD G. MAHIN, Associate 

 Professor of Chemistry in Purdue 

 University. 510 pages, 119 illustra- 

 tions, $3.00. 



A book that is broader in scope than 

 the usual text. It aims to produce in 

 the mind of the student a clear compre- 

 hension of the scientific development of 

 quantitative methods. It is especially 

 valuable to the commercial chemist since 

 it devotes nearly 250 pages to the latest 

 methods of "Analysis of Industrial Pro- 

 ducts and Raw Materials."
