Dear Paul;- The thing I disagree with is the number of DNA "Breadboxes" that would or could be sold. I can't imagine a single University that would be without one, not a single police department, a good many high schools and one heck of a lot of us independent collectors and arm-chair scientists. If you build it,---they will come----out of the woodwork if necessary. The only convergent example I can come up with is my brother---- who looks a lot like an English Bulldog. Art
