We have started an analysis of the sharp-lined superficially normal A3IVp star 95 Leo. We are using $2.4 \AA \mathrm {mm}^{-1}$ spectrograms covering $\lambda\lambda 3830-4934$ obtained with the 1.22-m telescope of the Dominion Astrophysical Observat

The superficially normal stars And (A2 V), Del (B6 III), Aqr (A1.5 V), and And (B9 V), which have ro- tationally broadened line profiles, are analyzed in a manner consistent with previous studies of this series using 2.4 A mm 1 spectrograms obtained

Following from previous papers of this study we present elemental abundance analyses of the sharp-lined bright Am stars 15 Vul and 32 Aqr. The values derived using fine analysis techniques are found using the stellar parameters, effective temperature
