  The masses of the spin-3/2 baryons are calculated to next-to-next-to-leading
order in heavy baryon chiral perturbation theory and partially quenched heavy
baryon chiral perturbation theory. The calculation is performed for three light
flavors in the isospin limit. These results are necessary for extrapolating QCD
and partially quenched QCD lattice calculations of the decuplet baryon masses.
