I found the statement  in the article that preceded the one David quoted
interesting in light of our discussion about the Albion Iron meteorite:

""It's doubtful they've
                                got the mother lode,
                                however, because the
                                lowdown is this:
                                Meteorites are solid --
                                if they're iron, they'd
                                be three times heavier
                                than a rock of a similar
                                size -- and won't have
                                bubblelike pockets or
                                pores. "

I can understand their thinking of the typical iron meteorite without
vacuoles as being heavier and not having bubble-like pockets, but what do
they mean meteorites don't have pores?  If there is one thing I have learned
on this list it is that meteorites, as well as tektites, are aerodynamically
shaped with pock marks.  I assume this is what they mean by pores.  Is this
correct?

Best Wishes,
