Thank you. I've been watching this thread in passive amusement (knowing the deal with Helium) while all the pseudo-scientist and pontificators plucked their woolied navels. It never ceases to amaze me how people on the Internet can so passionately argue convictions that are so completely and uttlerly wrong. With quotations, even! Mr. Landon has rendered the absolutely correct pronouncement on the helium issue, so can we drop this issue now, *please*? -Will On Mon, 17 Nov 1997, J.
