Russ Gardner is organizing a "Paul MacLean Festschrift" to be held in New England in July 1999. John Price, MD, & I will be speaking along with perhaps a dozen others.
MacLean had some rough treatment for a decade; Corey and others seem determined to bring the record about. You will find some material in recent copies of ASCAP (Across Species Comparisons and Psychopathology), available from Russ at rgardner@utmb.edu.
I'm still doodling with the concept of "My kid's in his lizard" for a few essays. You can get information on odors and effects on human behavior from Jim Kohl at jkohl@vegas.infi.net. Check also Howard Bloom's site at paleopsych.org.
