Michael

Correct weblink is http://www.qmig.net/thinsection

The other webpage is from my Queensland meteorites website with a pic of a
slide of WINTON 2 - WINTON 2 is another one I need to get micrographed as
a priority - it's probably the most scientifically significant meteorite
to ever come out of Australia... shhh... secret squirrel

Cole Creek and NWA 1955 are still there

I may put Mossgiel back - I personally think it was the best of the bunch
so far
