SA warmly thanks R. Michard for his wise suggestions on morphological classification, and Prof. G. Chincarini, whose scepticism prompted us to write this paper. We thank Dr. A. Naim for giving us the morphological type of the galaxies in his sample in a computer readable form. We also thank Chris Moss for convincing of the importance of understanding our results on morphological segregation. We thank G. Soucail for information concerning typical observations of distant clusters with HST.
