Recent uvby photometric work indicating possible CN variation among main-sequence stars in the Hyades is tested. Comparison of Reticon spectra of normal stars of similar temperature to five anomalous CN candidates in the Hyades demonstrates that there is no significant difference between the spectra of the program and comparison stars for four of the anomalous CN candidates in the wavelength region of CN 4216. The observed spectral discrepancy for the fifth program star appears to be the result of an incorrect temperature index as compared to previous observations of the same star. The source of the photometric anomaly remains unexplained.
