**Dispersion**, in optics, the same with the divergence of the rays of light.

**Point of Dispersion**, in dioptries, the point from which refracted rays begin to diverge, where their refraction renders them divergent.

**Dispersion of Inflammation**, in medicine and surgery, is the removing the inflammation, and restoring the inflamed part to its natural state.
