Dear Networkers: My apologies for posting a second time my message about my communiques with Mark Hirsch. I was off the network for several days and when I logged on this morning, the first message was one from the parkinsn listserver telling me that I could not post a message addressed the same way as it was sent out. So I thought that the message had been rejected and that I would fool the listserver by giving it a different address. So I sent it, and then began reading the messages. To my surprise, there was the orginal message.. Sorry about that! Lesson: Read the full set of messages before sending. But I usually like to do it right then. Bob Newbrough
