A PHYSICAL TREATISE O1V ELECTRICITY AND 

 MAGNETISM. By J. E. H. GORDON, B. A. Camb., Member of 

 the International Congress of Electricians, Paris, 1881; Manager of 

 the Electric Light Department of the Telegraph Construction and 

 Maintenance Company. SECOND EDITION, revised, rearranged, and 

 enlarged. Two volumes, 8vo, with about 312 full-page and other 

 Illustrations. Cloth, $10.00. 



"There is certainly no book in English we think there is none in any other 

 language which covers quite the same ground. It records the most recent ad- 

 vances in the experimental treatment of electrical problems, it describes with 

 minute carefulness the instruments and methods in use in physical laboratories, 

 and is prodigal of beautifully executed diagrams and drawings made to scale." 

 London Times. 



" The fundamental point in the whole work is HP perfect reflection of all that 

 is best in the modern modes of regarding electric and magnetic forces, and in 

 the modern methods of constructing electrical instruments." Engineering. 



A PRACTICAL TREATISE ON ELECTRIC LIGHTING. 



By J. E. H. GORDON, author of "A Physical Treatise on Electricity 

 and Magnetism"; Member of the Paris Congress of Electricians. 

 With Twenty-three full-page Plates, and numerous Illustrations in 

 the Text. 8vo. Cloth, $4.50. 



" This work has been in preparation for some two years, and has been modi- 

 fled again and again as the science of which it treats has progressed, in order 

 that it might indicate the state of that science very nearly up to the present 

 date." trom Preface.

Vol. II. TELEPHONE : Various Applications, Electrical Transmission of 

 Energy.

 "M. Hospitaller distinguishes three source? of electricity, namely, the decora 

 position of metals or other decomposable bodies in acid or alkaline solutions, 

 the transformation of heat into electrical energy, and lastly the conversion of 

 work into current giving rise to the three specific modes of force styled respect- 

 ively galvanism, thermo-electricity, and dynamic electricity. He gives a history 

 of the progress of each, from the first crude constructions of the pioneer to the 

 latest and most perfect form of battery, thus furnishing the a Indent of science 

 with a sufficiently copious text-book of the subject, while at the same time 

 attording to tn-3 electrical engineer a valuable encyclongedia of his profession. 

 1 he work prese its a most useful and thorough compendium of the principles and 

 practice o* electrical engineering, written as only an expert can write to whom 

 the abstruse by long study has become simple. The translator has acted the 

 part of an editor also, and has added considerable material of value to the origi- 

 nal text." New York Times.
