That someone would be me.  Sorry Dave, but you might want to go back and
review that exercise.  I claim that both of my statements above are true,
and easily proved.  Remember, the measurement in question here is Total
Dissolved SOLIDS.  Are you really going to claim that *only* solids can
produce measurable conductivity when dissolved in water?!  I hope not.

I won't plague the list unless there is interest, but it's quite easy to
sketch out an experiment which will demonstrate high-conductivity in the
presence of near-zero TDS.
