Scientific paper

Elemental abundances of the superficially normal early A stars 2 Lyn, omicron UMa and phi Aql are derived consistent with previous studies in this series, using spectrograms obtained with Reticon and CCD detectors. The derived elemental abundances of 2 Lyn are usually very close to solar. Both omicron UMa and phi Aql, which are considered to be hot metallic-line stars, show He underabundances as well as overabundances of many iron-peak and heavier elements.
