The conditions for rotational invariance of a Born-von Karman lattice model are re-examined. It is found that the Born-Huang conditions for rotational invariance are necessary but not sufficient. Some additional conditions are obtained which, together with the Born-Huang conditions, constitute a set of necessary and sufficient conditions. © 1966 The American Physical Society.
