Several weeks I posted an inquiry as to whether anyone knew of the organization/agency/museum which was circulating the exhibit of scientific photography based on the book and of the same title "On The nature of Things". Its hard to believe, but no one responded. Perhaps one of you "lurkers" out there presumed that I'd get dozens of responses and so didn't bother. Well, if you know, I'd appreciate hearing from you.
