There was also an error in "Haloperidol and Thyroid Storm" by William H. Hoffman, M.D., Gary Chodoroff, and Leonard R. Piggott (April 1978 issue). On page 485 the next to last sentence of the case report should read, "Free T4 10 days after admission was 7.0 ng/l00 ml . . ." The staff regrets these errors.
