Double Star Systems

Abstract

First Paragraph: The continual increase in the number and size and perfection of astronomical instruments, together with the progress in the skill of men that use them and study and measure and discuss their results, are ever leading astronomers into new avenues of research and into more refined methods of investigation. Astronomy, although the oldest of the sciences, is as vigorous and as prolific as the youngest of her sisters. It requires continuous and attentive reading of at least the more prominent of the technical astronomical journals to keep pace at all with the latest advances and to remain au courant with events.
