  In a recent experimental paper reporting a precise measurement of the muon
anomalous magnetic moment, Brown et al. claim disagreement of their result with
evaluations based on the standard model. This claim is based on comparison with
a single theoretical evaluation. It is pointed out that other equally
legitimate theoretical evaluations exist in the literature, with which the new
experimental figure is quite compatible. The claim of indications for new
physics beyond the standard model does not appear justified. In this version we
take into account corrections to one of the works quoted, we include a new
discussion at the end, and also minor errors are corrected. The conclusions
remain unchanged.
