  The mass differences between spin-1/2 and spin-3/2 baryons are compared to
the mass differences between spin-0 and spin-1 mesons. Results of simulations
for charmed hadrons in the quenched approximation from a tadpole-improved
anisotropic action are discussed in the context of other lattice calculations,
quark model predictions, heavy quark symmetry predictions and experimental
data.
