Incorrect Word in Text
In the article titled "Neuroendocrine Aspects of Primary Endogenous Depression: XI. Serum Melatonin Measures in Patients and Matched Control Subjects," published in the July issue of the Archives (1992;49:558-567), an error was made in the "Circadian Pattern of Serum Melatonin" section on page 561. In the left column, paragraph 2, lines 5 through 7 should have read as follows: "This approximated the method that was used by Lewy et al44,45 to determine the 'dim light melatonin onset' time (dim light defined as <300 lux)." The journal apologizes for the error.
