We have studied the ultraviolet energy distribution of the metal-poor supergiant HD 112374. We need a temperature T eff = 5500 + 100 K, logg = -0.3 ± 0.3 for a deficiency of Mg by a factor of 5 in order to find agreement between theoretical and observed energy distributions. A reddening E(B -V) ~ 0.1 is then required, consistent with its galactic latitude of +36°.
