Query: Internal Kinematics of Dward Spheroidal Galaxies   We discuss the quality of kinematic data in dwarf spheroidal galaxies, the
current interpretations of those data, and prospects for actually deriving the
mass profile in these galaxies. We then discuss stellar populations constraints
on some of the models that attempt to explain the kinematics and formation of
the dSph's.
