| Abstract: | Values for the ratio of total to selective absorption are estimated from optical measurements on Cepheids, their radial velocities, and an assumed rotational velocity model of the Galaxy. It is shown that there is no systematic variation ofR with galactic longitude on the basis of these measurements. |
