RE: "instant" powdered formalin

From:"Monson, Frederick C."

Hi John,

	I'm not faulting you, and the bags sound really good, but you don't
have NB Formalin, because there was likely no methanol included.  I know you
will still call it that, but, nonetheless, it isn't the same.  On the other
hand, it will be most likely be exactly like what everyone calls 4% buffered
paraformaldehyde.  

	It is becoming clear why death comes to the old.  It is required to
stave off total confusion, something from which the young are apparently
protected.

Regards,

Fred Monson
