Photon strength functions have been derived from discrete neutron resonance data for electric and magnetic dipole radiation using the methods of slow neutron time-of-flight spectroscopy. The data cluster reasonably well around strengths of $b(E1)\ensuremath{\cong}0.04$ Weisskopf units/MeV and $b(M1)=1.4$ Weisskopf units/MeV, respectively.NUCLEAR REACTIONS Measured ${\ensuremath{\Gamma}}_{\ensuremath{\gamma}\mathrm{if}}$, $J$, $\ensuremath{\pi}$, $\ensuremath{\sigma}(n,\ensuremath{\gamma})$; derived $〈{\ensuremath{\Gamma}}_{\ensuremath{\gamma}\mathrm{if}}〉$, $\frac{\ensuremath{\Gamma}}{D(E1)}$, $\frac{\ensuremath{\Gamma}}{D(M1)}$).
