Multiple Errors.—In the article, "Amitriptyline-Perphenazine Interaction in Ambulatory Schizophrenic Patients: A Controlled Study of Drug Interaction," published in the October Archives (32:1295-1307, 1975), the following errors occurred:

On p 1295, in line 5 of the synopsis-abstract, the dosage of amitriptyline-perphenazine should have read 125 —20 mg/day, not 20 mg/day. The same dosage error occurred on p 1296, in column 1, in the second line from the bottom of the section titled "Study Design."

On p 1299, in column 1, line 10 should have begun —.32, not +.32.

On p 1307, the second entry under the listing of "Nonproprietary Names and Trademarks of Drugs" should have read "Amitriptyline hydrochloride—Elavil." As published, the nonproprietary name was incorrectly given as "Chlorpromazine hydrochloride."
