  We examine the V_{CMB} velocities and Tully-Fisher distances of 83 ScI
galaxies and find that their velocities contain the same discrete velocity
components identified previously by Tifft. After removing the discrete velocity
components, the scatter remaining on the Hubble plot is in good agreement with
the Tully-Fisher distance uncertainties. Although there is, as yet, no physical
explanation for these discrete components, the fact that they appear to be
identical to those found previously by Tifft suggests that their reality needs
to be taken seriously.
