Deviations from the orbital radial-velocity variations of both components of Capella are analysed for periodicities using the radial-velocity spectrometer data published by Shen et al. (1985). The periodicities may indeed be present; the most likely periods are about 67 days and 10 days for Capella Aa and Ab, respectively.
