  It is shown that any left module A over a ring R can be written as the
intersection of a downward directed system of injective submodules of an
injective module; equivalently, as an inverse limit of one-to-one homomorphisms
of injectives. If R is left Noetherian, A can also be written as the inverse
limit of a system of surjective homomorphisms of injectives.
  Some questions are raised.
