On the Newtonian Limit of the Weyl Tensor
  In this note we wish to complement some recent work in the cosmological
literature concerning the Weyl conformal curvature tensor and its parts. In
particular, we shall give a clear-cut definition of the Newtonian limits of
electric and magnetic parts of the Weyl tensor. We also discuss that only a
subset of the relativistic equations is needed to obtain a closed system of
equations in the Newtonian limit.
