We have been carrying out digital surface photometry of galaxies using the plates taken with the 105-cm Schmidt telescope at the Kiso Observatory, a branch of the Tokyo Astronomical Observatory. Two dimensional V-band luminosity distributions of 26l galaxies in the Virgo and the Ursa Major regions have been compiled so far (Watanabe et al. 1982, Watanabe 1983). They form one of the largest samples of homogeneous surface photometric data. This discourse is to draw attention to some new results, which are summarized below, on the structure of galaxies derived from the analysis of the homogeneous sample. Detailed discussion will be given elsewhere (Kodaira et al. 1983, Okamura et al. 1983, Watanabe et al. 1983). Most of the sample galaxies are members of either the Virgo or the Ursa Major Clusters, both lying at nearly equal distance (Aaronson and Mould 1983). Their morphological types range from elliptical (T=-5) to Magellanic irregulars (T=10).
