		The antidote for any tendency to think water is well 
understood is to read
  Felix Franks  WATER.
	This slim volume is a standard antidote when we notice any 
student developing a belief that aqueous solutions of macromolecules 
are largely understood.  Franks has edited the definitive 
dozen-volume monograph on water which you can find in any good 
science library, but this little book is his summary  -  mainly just 
on water itself, the pure substance with the deceptively simple 
formula H2O.  It is an easy evening's read.  By about Ch 2 you'll be 
convinced that many key properties of water are not explained.  Near 
the end of the book Franks discusses briefly aqueous solutions, 
mainly of simple salts.   It will not by that stage surprise you that 
these are even less understood; and what little he has to say about 
macromolecules will leave the impression that even less is understood.
	Yet that is the type of chemical system in which an 
incompletely-described electrical system is said to have detected 
some unaccounted-for resonances.  Inferring 'exciting' Noo Eege 
conclusions is pathetic.  Less so is overconfident assertion that no 
such phenomenon could occur, just because we have no mechanism for it.
