Corrections
The observations reported in Dr. William Thornton's letter to the editor on page 302 of the March issue of the Journal were incorrectly linked to his work with the University of Chicago Drug Research Clinics. This work was in fact undertaken when Dr. Thornton was in private practice in Naples, Fla.
On pages 350 and 354 of the March issue of the Journal, Dr. Murray Morphy's name was misspelled
The staff regrets these errors
