Chemical Gradients in Globular ClustersFirst I will describe briefly some older work on chemical gradient in globular clusters. Then I will discuss some more recent data on the chemical and kinematical properties of 47 Tuc and Omega Cen, that leave us in little doubt about the reality of such chemical gradients.

Core and Tidal Radii of the Carina Dwarf Spheroidal Galaxy from UK Schmidt Telescope PlatesCore and tidal radii of the Carina dwarf galaxy are determined by fitting King dynamical models to number count radial profiles, derived from COSMOS data. These values are compared with those of the other six known Local Group dwarf spheroidals.
