The observations during the year comprise about 800 microinetrical 

 measures of previously-known double stars, and the discovery of about 

 70 new pairs, the most of which have been measured on three or four 

 different nights each. A number of prominent naked-eye stars, some 

 of which are mentioned in the contributions to astronomical periodicals, 

 are included in the list of new stars. Careful series of measures of many 

 of the most difficult of the binary systems have been made, and partic- 

 ularly those requiring a large aperture from the extreme closeness of the 

 components, or the faintness of the companion star.
