The attenuation of primeval adiabatic density perturbations during the recombination period is examined. Results are presented in the form of a transfer function for a large range of values of the cosmological density parameter (Omega)(h-squared). The damping mass MD associated with the transfer function is not a simple power law in (Omega)(h-squared). Values obtained for MD are found to agree very well with Peebles' calculation in the physically simple case (Omega)(h-squared) = 1:MD = 7.9 x 10 to the 11th solar masses. For (Omega)(h-squared) = 0.1 and 0.01, MD = 4 x 10 to the 12th and 1.6 x 10 to the 14th solar masses, respectively, are obtained. It is concluded that the transfer functions obtained appear to be reasonable for pancake theories of galaxy formation.
