Dear List,
   I had many replies from members of this list.
Bernd had the most complete list and wins the First
Prize. Harald Shehlik wins second prize because he
included more information, but his list did not
include as many cubic minerals as Bernd. Tom K. wins
the Proud Tom prize for his "Proud Tom" answer that,
"it depends on how big you cut the meteorite into a
cube". Thank you for all that participated!!!
  First Prize: 50grams of Potter, Nebraska. Second
Prize: Special impactite. Proud Tom Prize: a
meteorite. I will in Pt.2 send Harald`s answer.
  Perhaps someone on this list will kindly add these
answers to their website ((please cite Bernd Pauli,
Harald Stehlik and Dirk Ross (I contributed to three
of Bernd`s answers)if used)).
  Best to all, from Tokyo, Dirk Ross
