An absorption feature was detected at the location of the Wing-Ford band near 9916 A in high-quality CCD spectra of five elliptical galaxies taken with the Cerro Tololo 4-m RC spectrograph. Measurements reveal that the mean strength is 0.013 mag (1 sigma of the mean) and individual galaxy strengths have 1 sigma errors of the order 0.002 mag. The (3-4) band of the delta system of TiO with band head at 9986 A was also detected, suggesting that the observed Wing-Ford feature is affected by the (2-3) band of the delta system of TiO at 9899 A which is present in late giants. Therefore, this feature is not due exclusively to the FeH molecule strong in late M dwarfs.
