A comparative investigation of the temperatures, gravities and abundances of the AI Velorum stars and some selected δ Scuti stars and RR Lyrae stars has been carried out at Mount Stromlo during the past few years. Eleven AI Velorum stars, 6 δ Scuti and 6 RR Lyrae stars together with 6 established standard stars have been observed. The eleven AI Velorum stars comprise almost all those accessible from the Southern Hemisphere. The RR Lyrae stars were selected as examples of the weakest and strongest line stars of type a and c, and the 6 δ Scuti stars observed also represent the strongest and weakest line stars of the group.
