A statistical analysis of directional data for the 10-20 brightest galaxies in a sample of 55 clusters is presented. The data are derived from the digitization of Palomar 48 in. Schmidt telescope plates. The orientation of clusters, of each galaxy, the direction of the line joining each galaxy with the cluster center or with the brightest galaxy, and all possible relative angles between these directions are considered. Various statistical tests are applied and no significant alignment for galaxies fainter than the two first ranked cluster members is found. A strong alignment of the brightest galaxy major axis with the long axis of the parent cluster is confirmed. A strong alignment of the cluster major axis with the line joining the two brightest cluster members is found. This effect is stonger than the alignment caused by the ellipticity of clusters.
