----------------------------Original message---------------------------- I seem to remember reading something like this in some journal, perhaps in a letter to the editor, and also hearing about it from a visiting professor while I was in graduate school at UW(ashington -- lest somebody think it was aterloo or isconsin) in the early 1970s. I don't think this is a figment of your imagination, Darius, but, for the life of me, I can't figure out who it was that did it. vh -- \ / Virginia R.
