Recent continuum and line data in the far ultraviolet for ι Her (B3IV) and τ Sco (BOV) have been combined with published observations in the near uv and visible spectral regions and interpreted with the aid of the Kurucz (1979) line-blanketed model atmospheres. For ι Her and τ Sco, respectively, interpolated models of (Teff/log g) 17500±500K/3.75±0.15, and 31500±1500K/4.3±0.2 fit the observed continua from 900–6500Å and the profiles of Hγ and Hδ. Adopting these models, solar abundances are suggested for both stars.
