  Theoretical calculations of the hadronic contribution to the muon anomalous
magnetic moment utilize experimental data from e+e- annhilation and tau decay.
The data provide input to a dispersion relation. I contend that it is not
possible to put error bounds on the dispersion-relation calculation absent
proof - not presently available - that the amplitudes in question are
polynomially bounded. Examples are provided. Additional pertinent references
have been added to an earlier version of this posting.
