Abstract
As a guide and index to the great advance in knowledge of the stellar system that has taken place in the last thirty years, this volume will be found extremely useful. Commencing with constellations and star-catalogues, the author proceeds to spectral types and schemes of evolution, notably the giant and dwarf hypothesis that holds the field at present.
