We show that the D_n_- σ relation, used for estimating distances
to elliptical galaxies, needs a surface brightness correction. This
correction follows from the universality of the R^1/4^ law, and can be
derived analytically. It resolves the surface brightness bias problem of
the D_n_-σ relation noted earlier.
