Abstract
After demonstrating the equivalence of an approach of the author with an earlier one of Eichten and Feinberg as far as the general form of the spin-dependent quark-antiquark potential in order 1/m 2 is concerned we point out an inconsistency in the further assumptions which were made in both papers. We show that there is a relation between the various potentials which was violated by these assumptions. The correct treatment yields an, additional spin-orbit term which reverses the sign of the one obtained before and brings it into agreement with that of an effective scalar exchange.
