Abstract

An estimate of

α^{4} R_{\infty}

contributions to positronium and muonium hfs is made in somewhat greater detail than heretofore. Comparison with the most recent experimental data suggests that such additional corrections could well improve agreement between theory and experiment. Indeed, the one immediately calculable

α^{4} R_{\infty}

contribution almost totally accounts for present discrepancies.
