We consider the $a {1} (1260)$ contribution to photon and dilepton productions from hot hadronic matter. The effective lagrangian with $\pi, ho$ and $a {1}$ discussed by Ko and Rudaz is employed, which successfully reproduces the $\Gamma (a {1} ightarrow \pi \gamma) = 670$ keV. Our results for the photon production rate are comparable to those obta
