Abstract Measures are presented for 302 double stars photographed on 657 plates with the 36-in. Lick refractor in the period between 1945 and 1962. The data provided include the observing epochs, the rectangular coordinates of the secondary components with reference to the respective primaries, the mean errors of a single measurement, the computed mean errors, the double-star separations, and the position angles both for the observing epoch and reduced to the equator of 2000. An additional 561 unmeasured plates of acceptable quality obtained between 1948 and 1960 are listed.
