In the Letter "Reconstructing the Primordial Spectrum of Fluctuations of the Universe from the Observed Nonlinear Clustering of Galaxies" by A. J. S. Hamilton, P. Kumar, Edward Lu, & Alex Matthews (ApJ, 374, L1 [1991]), equation (5) is incorrect. The equation is supposed to be a fit to ξ^bar^ = V^-1^ {integral from 0 -> r} ξdV for linear cold dark matter (CDM), but in fact formula(5) given in the Letter is a (good!) fit to V^-2^ {integral from 0 -> r} ξ_12_dV_1_dV_2_, which is commonly called σ^2^ in the literature. A good fit to the intended quantity V^-1^ {integral from 0 -> r} ξ dV for linear CDM is... See Journal. The same error was also propagated into Figure 1 of the Letter "Measuring Omega and the Real Correlation Function from the Redshift Correlation Function" by A. 3. S. Hamilton (ApJ, 385, L5 [19923). That Letter is otherwise unaffected.
