Spectrophotometric data for 26 QSOs are combined to show that the average Ly-alpha/H-beta intensity ratio in QSO spectra is most probably at least eight times smaller than is expected from a recombination spectrum. Analysis of the continuous energy distributions of 20 QSOs indicates that the continuous spectra of at least two of these objects are modestly reddened while those of the remaining objects are not appreciably reddened. Evidence is discussed that the Ly-alpha emission is unlikely to have been strongly attenuated by reddening or any other means, and it is concluded that the H-beta emission has been enhanced by a large factor.
