Typo

Kevin Muse of the University of Wisconsin at Milwaukee alerts me to this mistake on p. 68 3. b "For this statement..." should read "From this statement..."  Kevin has also compiled a page-consecutive file of the corrections and additions to OHCGL made thus far which I intend to post soon—only the serious ones are included, not the silly ones. This way you will be able to print it out and keep it with your hard copy.  Thanks, Kevin!
