Observations of the quasar PG 0026+129 with the International Ultraviolet Explorer have determined its L-alpha intensity. In conjunction with visual and infrared observations by Puetter et al. (1978), a L-alpha/H-beta/P-alpha ratio of 6:1:1.4 is derived. The ratios differ from those found in 3C 273. The implications of these observations are discu…
