In the Research Article ``A thermodynamic scale for the helix-forming tendencies of the commonly occurring amino acids'' by Karyn T. O'Neil and William F. DeGrado (2 Nov. 1990, p. 646), figure 3 contained some errors. The label of the y-axis should have read ``log\[Peptide\] (µM), and the symbols should have been labeled as follows: Ala (⋄); Phe (□); ile (*); and Asp (▵).
