  We reexamine critically the chiral expansion for the baryon magnetic moments
including the contributions from loops which involve intermediate octet and
decuplet baryons. We find that, contrary to some claims, the nonanalytic loop
contributions of orders $m_s^{1/2}$ and $m_s ln m_s$ are of the same general
size because of large coupling factors for the latter, and that the decuplet
contributions are as large as the octet contributions and must be included in a
consistent calculation. There is no clear evidence of the convergence of the
chiral series. The adequacy of the theory will not be established until
dynamical models are able to calculate the contributions from the counterterms
that largely hide the loop effects in fits to the data.
