One of the most important and most interesting of the known binary systems. The shortness of its period, the rapid movement in space of both components, the relative nearness of this system to our own, and the extreme inequality in magnitude and closeness of the stars, all combine to give this a leading place among the binary stars. It is at all times an object of considerable difficulty, and the reliable observations will necessarily be confined to the larger retractors. It is an excellent test for the definition of any object glass, however large, and no instrument, whatever its aperture, can deal with a pair of this class unless the figure of the objective will compare favorably with the Alvan Clark standard. The close companion was discovered with the 18½-inch of the Dearborn Observatory while measuring the 9 m optical companion.

The binary character of the close pair is established by the measures. The motion is retrograde, with perhaps a slow increase in the distance. The system has a proper motion of 0*079 'n 'he direction of 1 54? 1 (Boss). This movement is in the direction opposite the Herschel companion, and the distance of that star is there- fore increasing annually by the proper motion of AB.
