Abstrakt: The density gradient term in the free-energy expression for a fluid can, as previously shown, be corrected so that the effect of this term on the correlation length parallels the effect of the other terms. It is shown that this same correction improves the values of the critical exponents when applied to Wilson's simplified version of the renormalization theory.
