Radial-velocity measures are presented for 225 stars, most of which are dwarf K and M stars. The data were obtained with the CfA digital speedometer, whose uncertainty is less than 1 km/s. Calibrations of three earlier radial-velocity studies and comparisons with three other contemporary ones lead to the evaluation of the standard error for an individual star as determined in each investigation. The data from two masks, matching solar type and M type stars, form a ratio that measures stellar surface temperature quite closely and appear to be useful in detecting the presence of unseen companions. A few previously unrecognized binaries have been detected; those with most certainty include stars nos. 366B, 453, and 46A of the McCormick lists of dwarf stars.
