The magnetic scattering rate of Fe in Mg is measured as a function of temperature by means of weak localization. It shows a strong temperature dependence which is attributed to the Kondo effect. At low temperatures Nozi\`eres predicted a Fermi-liquid behavior for the electron system plus the Kondo impurity with no magnetic scattering. Weak localization allows a check of the applicability of the Fermi-liquid theory.
