This book is a detailed collection of observations of double stars made by the author with the 400 mm equatorial telescope of the Washburn Observatory over a period of several years.

The author provides detailed information on the methods and instruments used in making the observations, including a discussion of the errors and limitations of the measurements. The book also includes a comprehensive summary of the data collected, with mean values for the position angle and distance of each double star observed.
