CONTENTS : The " Generation " and Conduction of Electricity. Copper, 

 Aluminium, and other Conducting Materials. Energy. The Kelvin. 

 Electricity. Continuous Electricity and Ohm's Law. The Magnetic Field. 

 Conductors Moving in a Magnetic Field. Alternating Electricity. Induct- 

 ance. The Magnetic Circuit. Insulating Materials. 



The Engineer. " A rapid glance at the illustrations contained in this book is sufficient 

 to show that it differs very materially from most others having the same title. Indeed, it 

 may be said that the volume possesses that desirable but unusual feature originality. A 

 chapter on the magnetic field contains information which the student will find well worth 

 acquiring, and the same applies to that section of the book which deals with conductors 

 moving in a magnetic field. The alternating current section is also good, and in a number 

 of places it possesses the merit of originality. The book, as we have already intimated, is 

 written on practical lines, and it is a decided improvement on most books we have seen 

 having for their title the word ' Electricity. "
