   To derive a reliable estimate for the darkmatter amound in elliptical
   galaxies, we propose to observe NGC4636 for 100 ksec. This
   observation determines whether the darkmatter only belongs to
   individual galaxies or there is a component in the cluster scale. The
   proposed target is one of the brightest elliptical galaxies, and its
   isolated location gives ideal opportunity for the present study.
