High signal-to-noise ratio measurements of the S III lines 18.71 and 33.47 microns from the galactic center, Sgr A West, are reported. The average electron density is calculated for the S III-emitting region and is found to be 1800 + or - 500 per cu cm. This value is much less than the rms electron density of the clumps as derived from radio observations. The implications for various models are discussed. The S III result is consistent with the electron density previously derived from low signal-to-noise ratio measurements of the O III lines at 88 and 52 microns, if newer values are used for the O III atomic constants.
