Hi Elton, Listees,

I'm appreciating everyone's super comments and will respond to these kindly
offered ideas (optimistic, realistic and negative) and friendly concerns
weighed together, in one email after hopefully even more feedback.

But Elton needs more data, this is the best I can do (and I went to work on
it right away). I am very sorry not to have my stereo microscope up and
running, all the big toys are currently in storage for reasons beyond my
control which are frustrating. Same link, www.diogenite.com/maybe.html .
Marsbug had to go and is replaced by picture #6, a close up which I hope can
bridge some of the gap on surface detail. Please click on the smaller image
it to see the full size image if this is useful data for you.

still hope to get more comments...

Best wishes, Great Health,
Doug
