The abundances of 11 elements and the upper limits of three other elements in a peculiar B-type star, HR 1094, have been determined. This star exhibits unusually strong lines of Cl II and Co II. These elements were found to be overabundant by 3.8 dex and 3.3 dex, respectively. The abundances of Ti, Cr, Fe, Sr, Pt, and Hg are enhanced while those of Sc and Ni are not. Several light metals, Mg, Si, and Ca, were found to be underabundant. The abundance pattern found in HR 1094 is quite unique among B-type CP stars, showing the composite abundance characteristics of both Hg-Mn stars and magnetic stars.
