Scientific paper

This paper presents LTE analyses of two sharp-lined early B stars,
γ Pegasi and ι Herculis, based on co-added IIaO and Reticon
2.4 Å spectrograms of the photographic region. Most of the derived
abundances are close to solar. Both stars have definite microturbulences
which probably are related to the instability of their photo spheres.
