I sent the last Current Science Reviews in two parts and two versions- the second after I learned to avoid the confusing word wraps caused by exceeding 65 characters per line. On returning from a short absence, I found robotic messages from the listserv to the effect that the second version had been rejected because it didn't sufficiently differ from the first. If anybody wants the cleaned-up second version let me know, and I'll send it again. Cheers, Joe J. R. Bruman (818) 789-3694 3527 Cody Road Sherman Oaks CA 91403
