The method of "sosie" galaxies is applied to a large sample of galaxies extracted from the BGP catalog of H I line data and the Second Reference Catalogue of Bright Galaxies. The "sosies" of 14 calibrating galaxies (primary calibrators and galaxies in the nearest groups) are defined as those having the same parameters, either (1) morphological type T, axis ratio R, and maximum rotation velocity VM or (2) T, R, and luminosity index Λc. These two sets provide respectively for 127 and 72 galaxies (28 are in common) distance moduli directly derived from apparent magnitudes and/or diameters. The distances obtained here are compared with various other determinations; the agreement is generally good.
