We derive distances for 64 dwarf ellipticals (dEs) in the direction of the Virgo cluster's (VC) core, by means of the luminosity-profile curvature (L-n) relationship and by means of their global scalelengths, which we find to be correlated with the shapes of their surface-brightness profiles. The great depth we find in the spatial distribution of Virgo dEs is not consistent with a unimodal distribution due to a single spherically symmetric concentration of galaxies. This depth is also sufficient to explain much of the disagreement over the VC's distance, and thereby much of the Hubble-constant (H_0) controversy.
