Scientific paper

A differential abundance analysis is presented for three supergiant stars all having weak N II lines. All three stars are members of the same loose association, thus any abundance anomalies reflect the composition of the interstellar material from which they were formed. The association is located at about 1500 parsecs from the sun and has a galactic latitude of plus 1 degree.
