We report on the detection of two Zn i lines at 4722.15 Å and 4810.53 Å in the high-quality spectrum of the very metal-poor post-AGB star HR 4049, which was obtained with the High Dispersion Spectrograph attached to the Subaru Telescope. The strengths of these lines indicate an appreciable underabundance of Zn by $\sim-1.3 \,{\rm dex}$ relative to the Sun. The fact that this volatile element, simi...
