The help I have received from medical and scientific consultants has been essential to this work, and I particularly want to acknowledge the contributions of Dr. John Burger Dr. Paul Cooper, Dr. Don Klein, Dr. Robert Naiman, Dr. Christina Sekaer, psychologists Aphrodite Clamar and Elizabeth Slater, and for their work on soil sample analysis, Cullen Hackler and Paul Lander. I wish to express my thanks to Joseph Santangelo, Travis Whitehurst and Lew Willis, researchers whose efforts have enabled me to pursue certain avenues of investigation in these cases. Two colleagues in particular‹David Jacobs and Joseph Nyman - have been invaluable friends, confidants, critics and careful readers of this manuscript; I am very much in their debt. They have supplied me with major amounts of advice, information and caution‹though not necessarily in that order - and have thereby helped to make this a stronger book. Finally, I would like to thank April, my wife, and Grace, my daughter, for tolerating the theft of family time that this project has represented. I could say that it will never happen again, but I know I would not be believed. Despite this, I want them to know how much their forbearance and understanding has contributed to the creation of my book and how essential their spoken and unspoken support has been to my life.
