Evidence is presented that HR 4594 and HR 8210 are pulsating marginal Am stars. It is suggested that (1) classical Am stars do not pulsate, (2) evolved Am stars may pulsate, and (3) marginal Am stars may pulsate. It is further suggested that, within the Am domain, temperature, age, rotation, and pulsation are sufficient to determine whether a star will be Am, marginal Am, or spectrally normal.
