Folks,
  I noticed that the arrows in the chemical reactions did not show up, at
least in the e-mail reader that I am using (PINE). I will check with my
computer at home and if the arrows are missing with my other browser, I
will resend the chemical reactions so that they are more readable. Sorry
about the snafu. Check back in 12 hours or so! :-)

Regards,
Charlie
