Jones-- What about Levi's Ni isotopic changes? Does your 1<COP<2 fit with those observations, which seem to suggest more than your f/H idea? Or were both of Levi's isotopic analyses incorrect as well? Bob, Well - the analyses were correct, insofar as you do not look deeper. However, I am fully convinced that there were no real isotopic changes. Rossi had physical control of the samples which were tested. Enough said.
