We report the results of a new experimental search for a permanent electric dipole moment of {sup 199}Hg utilizing a stack of four vapor cells. We find d({sup 199}Hg)=(0.49{+-}1.29{sub stat}{+-}0.76{sub syst})x10{sup -29} e cm, and interpret this as a new upper bound, |d({sup 199}Hg)|<3.1x10{sup -29} e cm (95% C.L.). This result improves our previous {sup 199}Hg limit by a factor of 7, and can be used to set new constraints on CP violation in physics beyond the standard model.
