  We report an inelastic light scattering study of the effects of
charge-ordering on the spin-, charge-, and lattice-dynamics in ${\rm
Bi}_{1-x}{\rm Ca}_{x}{\rm MnO}_3$ $(x>0.5)$. We find that charge-ordering
results in anomalous phonon behavior, such as the appearance of `activated'
modes. More significantly, however, the transition to the CO phase results in
the appearance of a quasielastic scattering response with the symmetry of the
spin chirality operator ($T_{1g}$); this scattering response is thus indicative
of magnetic or chiral spin fluctuations in the AFM charge-ordered phase.
