A PHYSICAL TREATISE ON ELECTRICITY AND MAGNET- 

 ISM. Bj J. E. H. GoEDOX, 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 its 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 TREAT!:JE ON ELECTRIC LIGHTING. Bj J. 



E. H. GoEDON, 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 modified 

 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." — From 

 Preface.

" M. Hospitaller distinguishes three sources of electricity, namely, the decom- 

 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 respectively 

 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 student of science with a suffi- 

 ciently copious text-book of the subject, while at the same time affording to the 

 electrical engineer a valuable encyclopaedia of his profession. The work presents 

 a most useful and thorough compendium of the principles and practice of 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 original text," — Xeio York Times,
