An attempt to detect abundance anomalies in the secondary component of U Cep is reported. A spectral comparison of the secondary of U Cep with single stars of similar spectral type and luminosity class reveals no substantial spectral differences, with the exception that the calcium H and Ê lines in the spectrum of the secondary of U Cep are weak and appear to be filled in by emission.
