general are discussed in detail and modern charge transfer theories and their applica- tion to insulator electrodes are examined.

Chapter 1 presents a useful survey of special relativity. It is followed by calculations of the force between moving charges, showing that the weak magnetic interaction can be interpreted as a second-order relativistic effect. The electric and magnetic fields near a moving charge are used in Chapter 4 to develop Maxwell's equations for systems of point charges moving with uniform velocities; accelerating charges are considered in an Appendix. The scalar and vector potentials are treated in Chapter 5 and relativistic electromagnetism in the final Chapter. Problems are included in most Chapters. The book has been extremely carefully written and is easy to follow. The author is a thoughtful and helpful guide, but the quick student may find the style too slow and repetitive. The book is recommended to those who have some knowledge of electromagnetic theory -- it should help to clarify their understanding of this important subject. The MKSA system of units (S.I.) has been used.
