The analysis of the spatial orientation of 118 galaxies with |mₚ 14.0| in the main ridge in the Perseus supercluster shows that the rotation axes of galaxies tend to be aligned with the supercluster plane. The projections of the rotation axes of galaxies in the supercluster plane tend to avoid the directions just either side of the main concentration of galaxies in the supercluster.
