}A relativistic four-dimensional wave equation, derived previously, for bound states of a two-body system is discussed further. For any "instantaneous" interaction function an exact three-dimensional equation is derived from it, similar to, but not identical with, the Breit equation. A perturbation theory is developed for a small additional non-instantaneous interaction.
