Two spectrograms of the planetary nebula N.G.C. 5873 ( α=15h6m.3; δ=-37°43′ ) were obtained with the one-prism spectrograph at the D.O. Mills Observatory, Santiago, Chile, in March, 1913. The mean of the measures of these two plates by Miss HOBE, Mrs. MOORE, and Mr. MOORE give for the radial velocity of the nebula with reference to the Sun -136 km per second. Its velocity in the line of sight referred to the stellar system is therefore -133 km per second. The velocity determinations depends upon measures of the nebular lines λλ4340, 4686, 4861, 4959, and 5007.
