High-resolution spectroscopic measurements of Mercury were made at \(4227 \AA\) to search for neutral calcium in the atmosphere. An upper limit to the intensity is \(9.0 \mathrm{kR}\); the corresponding \(\mathrm{Ca}\) column abundance is \(<7.4 \times 10^{8}\) atoms \(\mathrm{cm}^{-2}\) with a \(\m
