Progress in the study of visual binaries depends upon the existence of a series of astrometric observations in addition to observations of their relative motions. The present paper discusses the proper motions, parallaxes and mass-ratios of visual binaries, the detection of astrometric binaries and the photographic astrometry of faint binaries.
