The weak line of Hg II located at 5677.10 Å is not detected in a series of ESPaDOnS I profiles of the bright HgMn SB2 star HD 32964 (66 Eri). This non-detection sets a limit on the abundance of mercury below which this line ceases to be useful. Line synthesis is used to measure the abundances of twenty elements in one component of the system, 66 Eri B, the HgMn star. The following excesses/deficiencies are found: helium (-0.70 dex), carbon (-0.52), oxygen (-0.70), neon (-0.30), magnesium (-0.40), silicon (-0.70), phosphorus (0.00), calcium (-0.85), scandium (-0.48), titanium (+0.36), chromium (+0.52), manganese (+0.52), iron (-0.70), gallium (0.00), strontium (-0.09), ytrium (+2.00), zirconium (0.00), xenon (0.00), baryum (+1.60) and mercury (+4.73). The status of 66 Eri B as a HgMn star is reinforced.
