The 12 September issue of New Scientist has an article on the tools
and weapons used by Otzi, the 'iceman' found in a glacier in the Alps
a few years ago. The article describes a forensic examination of the
objects. Unfortunately, it is not accessible from the New Scientist
web site and is too long to send in its entirety to the list. If
anybody wants to read the article and can't get their hands on the
relevant issue of the magazine, let me know off-list and I'll send
you a copy.
