## Electrodynamics of continuous mediaCovers the theory of electromagnetic fields in matter, and the theory of the macroscopic electric and magnetic properties of matter. There is a considerable amount of new material particularly on the theory of the magnetic properties of matter and the theory of optical phenomena with new chapters on spatial dispersion and non-linear optics. The chapters on ferromagnetism and antiferromagnetism and on magnetohydrodynamics have been substantially enlarged and eight other chapters have additional sections. |

When spatial dispersion is taken into account, it is often appropriate, and does

not affect the generality of the theory, to write

E = - - ?5 , div B = 0, (103.3) c ot curl B = - ^ , div D = 0, (103.4) c ot without using
