Are the globular clusters with significant internal [Fe/H] spreads all
  former dwarf galaxy nuclei?
  In this contribution the hypothesis that the Galactic globular clusters with
substantial internal [Fe/H] abundance ranges are the former nuclei of disrupted
dwarf galaxies is discussed. Evidence considered includes the form of the
metallicity distribution function, the occurrence of large diffuse outer
envelopes in cluster density profiles, and the presence of ([s-process/Fe],
[Fe/H]) correlations. The hypothesis is shown to be plausible but with the
caveat that if significantly more than the current nine clusters known to have
[Fe/H] spreads are found, then re-evaluation will be required.
