places by selections from Professor Maxwell’s well-known larger 
work on Electricity and Magnetism. That this is necessarily 
labors were so prematurely interrupted, it does not seriously 
end for which it was planned. The author’s design, as is stated 
in the fragment of the preface which he left for us, is to “ present 
in as compact a form as possible those phenomena which appear 
to throw light on the theory of electricity, and to use them each 
in its proper place for the development of electrical ideas in the 
mind of the reader.” There are many conscientious students of 
electricity who are unable to master the mathematical methods of 
Professor Maxwell’s larger treatise and yet who desire to obtain 
an accurate knowledge of the fundamental theories of the subject ; 
to them the present volume, in which mathematical analysis is in 
general avoided, will be invaluable. In fact it would be impossi- 
ble for any one, however far advanced, not to gain new ideas or to 
see old ones in a clearer light, after a careful study of Professor 
Maxwell’s lucid exposition of the subject.
