Abstract
Elemental abundances of the early A stars epsilon Ser, 29 Vul and sigm a Aqr are derived consistently with previous studies of this series us ing spectrograms obtained with Reticon and CCD detectors. The derived abundances confirm that epsilon Ser is a definite Am star. 29 Vul show s evidence for a weakly operating Am star phenomenon, sigma Aqr, a hot Am star prototype, has abundances similar to those of o Peg, another class prototype.
