Abstract Twenty-seven observations of Cephei made in 1950 with the Mills spectrograph are combined with observations obtained in 1907 and 1923 in order to determine a definitive velocity-curve. The following conclusions are drawn: (1) there is no evidence of any long-period change in the mean velocity; (2) there is no evidence of change in the form of the velocity-curve; (3) the mean velocity is - 16.1 + 0.2 km/sec; the velocity range is 39.4 km/sec. An attempt is made to ascribe the velocities measured to some identifiable level in the stellar atmosphere.
