TL;DR: In this article, the role of time-reversal symmetry in determining the possible forms of macroscopic laws has been clarified, as well as the criteria for the occurrence of spontaneous electric and magnetic moments.
Abstract: In an earlier paper [Amer. J. Phys. 36, 735 (1968)] of the same title one of us described a particularly simple method by which symmetry considerations can be applied to determine the possible forms of macroscopic laws. In this sequel we clarify the role of time-reversal symmetry, describe more fully the criteria for the occurrence of spontaneous electric and magnetic moments, discuss the application of the method to magnetically ordered systems, and correct a number of errors in the tables.
