Colleagues --

Thank you for your helpful comments about the "colloquium" I tested on 
May 8.

I have incorporated them into the "final" version of the talk, now 
posted on my web site.  The new version also attributes the figures 
correctly (I believe).

You may download the talk (two resolutions) at

Please feel free to make additional comments.  And to borrow anything 
you like for your own colloquia!

Thanks again --

Jon Bagger
