Corrections
In "Evidence for an Endogenous Inhibitor of Platelet MAO in Chronic Schizophrenia" by Wade H. Berrettini, M.D., and Wolfgang H. Vogel, Ph.D. (May 1978 issue) there are two errors in table 1 (p. 606). Under the column heading "Dialysis Experiment with Dopamine as Substrate" for the row entry "Mixed with normal platelet-poor plasma," the Vmax value should be 13 rather than 14 and the Km/Vmax value should be 0.23, not 0.21. The staff regrets these errors.
