The abundances of eight elements (C through Fe) were determined in the primary star of the short-period Algol-type binary RZ Cas relative to the A3 V spectroscopic standard star $\alpha$ PsA. Definite under-abundances (by $-0.45 \,\mathrm{dex}$ or more) of Mg, Si, Ti, Cr, and Fe were established. On the other hand, light elements C and O show solar abundances, and Ca is slightly under-abundant ($\...
