The weak line of Hg II located at 5677.10 Å is used to measure the mercury abundance in the most massive component of the SB2 HgMn star HD 173524 (46 Dra). This line is detected at 3σ above the noise in the adjacent continuum. The synthesis of this line, confirms a large overabundance of mercury, about +5.00 dex, which is less than the excess derived from the 3983.93 Å line in earlier studies. Spectrum synthesis yields estimates of the abundance deficiencies/excesses for sixteen other elements. Helium, carbon, oxygen, magnesium, silicon, chromium and iron are depleted. Phosphorus, titanium, manganese, gallium, strontium, yttrium, zirconium and barium are overabundant. Platinum is very overabundant. For several elements, these new abundances differ from earlier measurements.
