" This may indicate that many of the cluster variables of the galaxy were originally members of the same extra-galactic cluster or ; In a recent paper Dr. R. E. Wilson discusses the proper motions of seventy Cepheid variables. From a study of the known radial velocities of a few, Dr. ^^â iJson deduces the velocity of the Sun relative to these stars, and from their average peculiar motion he computes the mean A Near Stellar Neighbour The spectroscopic parallax of the fifth-magnitude star Epsilon Indi has been determined at Harvard. The distance deduced from this measuremtnt is seven lihgt- years. If confirmatorv results are obtained, it will be safe to conclude that this small star is one of our nearest stellar neighbours. Recent research has shown that in the region near to the Sun, and probably throughout the stellar system, the dwarf stars consider- ablv outnumber the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original London [etc. ] Professional and Ind
