Dear Professor Spiegelmann:
It is our pleasure to send you tearsheets from the June issue of PLAYBOY Magazine and call your attention to the article “Second Genesis” by Mac Gunther.
We would be delighted to hear—and would certainly value—any comments you have concerning this article which we might use in our Letters to the Editor column.
