THE ELECTRIC LIGHT: ITS HISTORY, PRODUOTIOIT, AND 



APPLICATIONS. By Em. Alglave and J. Boulaed. Translated 



from the French by T. O'Conor Sloane. Edited, with Notes and 



Additions, by C. M. Lungren. With 250 Illustrations. 8vo. Cloth, 



$5.00. 



" Not one of the recent scientific publications was more needed or is more 

 likely to be eagerly welcomed than a clear, exhaustive, and authoritative account 

 of the application of electricity to the production of light. "We are indebted to 

 Messrs. Appleton for issuing, in a large volume of 450 pages, illustrated with 

 several hundred woodcuts, an English translation of the well-known treatise by 

 MM. Alglave and Boulard." — New York Sun. 



ELECTRICITY AND MAGNETISM. By Fleemixg Jenkin, Pro- 

 fessor of Engineering in the University of Edinburgh, Illustrated, 

 and Index. With Appendix on the Telephone and Microphone. 

 12mo. Cloth, $1.50. 



" The plan followed in this book is as follows : First, a general synthetical view 

 of the science has been given, in which the main phenomena are described and 

 the terms employed explained. If this portion of the work can be mastered, the 

 student will then be repdily able to understand what follows, viz., the description 

 of the apparatus used to measure electrical magnitudes and to produce electricity 

 under various conditions. The general theory of electricity is permanent, depend- 

 ing on no liypothesis, and it has been the author's aim to state this general theory 

 in a connected manner, and in such simple form that it might be readily under- 

 stood by practical men." — From the Introduction. 



ELEMENTARY TREATISE ON NATURAL PHILOSOPHY. 



By A. Peivat Deschanel, formerly Professor of Physics in the Lycee 

 Louis-Ie-Grand, Inspector of the Academy of Paris. Translated and 

 edited, with Extensive Modifications, by J. D. Everett, Professor of 

 Natural Philosophy in the Queen's College, Belfast. Sixth edition, 

 revised, complete in Four Parts. Illustrated by 783 Engravings on 

 Wood, and Three Colored Plates. 



Part I. Mechanics, Hydrostatics, axd Pxettmatics. Cloth, $1.50, 



Part n. Heat. Cloth, $1.50. 



Part III. Electeicity and Magnetism. Cloth, $1.50. 



Part IV. Sound and Light. Cloth, $1.50. 



Complete in one volume, 8vo, with Problems and Index. Cloth, $5.70. 



" Systematically arranged, clearly written, and admirably illustrated, showing 

 no less than 783 engravings on wood and three colored plates, it forms a model 

 work for a class of experimental physics. Far from losing in its English dress 

 any of the qualities of matter or style which distinguished it in its original form, 

 it may be said to have gained in the able hands of Professor Everett, both by way 

 of arrangement and of incorporation of fresh matter, without parting in the trans- 

 lation with any of the freshness or force of the author's ic^i.''^ — Saturday Review.
