Please reply to the List when answering Lorraine! I have a 
watermark research project long since abandoned when our 
carbon-14 source, which used to give me betaradiographs, 
became unstable and we could not afford to replace it. The 
new methods are of great interest to me (I was 
unfortunately unable to attend the Watermarks conference).
