Friends, I was off-line for 3 days, as the lightning zapped my poor modem--- I had to suspend mail as it was piling up from 4 lists. A subject heading today on Kees Papp's message to Wendy Tebay refers to "carbon monoxide"-- if Wendy or anyone else posted a reply to the question about carbon monoxide & PD which I posted for a friend, could you please re-send it to me person- ally? I'd hate to miss info that I could pass on to him. Thanks --it's good to be back in touch. Camilla Flintermann
