More information will be posted when available.
Note: Three phone messages were left with Dr. Butler's staff at the office in Ottumwa, Iowa between 1/15/99 and 2/5/99, asking for more information on the study, and a copy if possible. SERF's number, and email address were left for a response. - Editor
Feb 2000: Fourth attempt. Still no response. - Editor
May 2000: Editor can only conclude that the study does not exist, or if it was done, Dr. Butler does not wish to publicize the study.
