Elemental abundances of 28 And (A7 III) and 99 Her (F7 V), which have modest rotational velocities, are derived in a manner consistent with previous studies in this series of papers. The values for 28 And, a δ Scuti variable, show that it is slightly metal‐poor, but not a classical Am star. 99 Her, which is somewhat more metal‐poor, has a rather small microturbulence for its spectral type.
