John:

I'm not sure if you are asking me something about my sodium polytungstate
question, or, as I suspect, replying to "Mike."  At any rate, several
people have replied and given me the address of two U.S. vendors who handle
the chemical, and I can give you the information if you wish.  Thanks to
all who responded!

Steve
