It is suggested that rotating cores such as those (both rotating and contrarotating) presently discovered in four out of seven slowly-rotating elliptical galaxies may exist in a large portion of elliptical galaxies. Attention is given to such possible explanations for contrarotation as the merging of galaxies and the counterspin-up of the galaxies' outer regions due to interactions in the early stages of galactic formation. The four galaxies discussed are NGCs 4365, 4406, 4494, and 5322.
