The velocity dispersion of galaxies on scales of $r\sim1h^{-1}$ Mpc,$\sigma_{12}(r)$, may be estimated from the anisotropy of the galaxy-galaxycorrelation function in redshift space. We present a reanalysis of the CfA1survey, correct an error in the original analysis of Davis and Peebles (1983),and find that $\sigma_{12}(r)$ is extremely sensitive to the details of howcorrections for infall into the Virgo cluster are applied. We conclude that arobust value of $\sigma_{12}$ cannot be obtained from this survey. We alsodiscuss results from other redshift surveys, including the effect of removingclusters.Comment: 12 pages, uuencoded(latex file + 2 Postscript figures), uses aas  macro
