A plasma model for the plasma structure function results in a spectrum of scattered light very different from that associated with a constant red-shift, implying that the "Wolf effect" cannot be involved to perturb the cosmological distance scale.8 pages, plain TeX format, 6 uuencoded postscript figures included, Caltech Preprint No. MAP-150Nuclear Theorytext
