A free-energy shift of the conduction electrons due to magnetic impurity immersed into an otherwise pure metal is calculated up to the fourth order in the $s\ensuremath{-}d$ exchange interaction. The results obtained show that there appears no anomalous term of the form ${T}^{n}\mathrm{ln}T$ up to this order in the magnetic-field-independent part of the free energy and that anomalous $\mathrm{ln}T$ terms are included only in the magnetic-field-dependent part.
