D. ; Borgman, E. R. Abstract Plate series obtained at the 61-cm Sproul refractor of Swarthmore College were processed during the time October 1982 to December 1983. Parts of some plate series had been measured previously. The present investigation involves an evaluation of the entire material, taking into account 58 trigonometric parallaxes and 14 binary-star mass ratios. Table I lists the parallax results. The measured components of the annual motion are to three decimals of arc seconds. A summary of the mass-ratio results is provided in a second table. All observed objects are briefly discussed.
