Orbits are presented for four more ninth-magnitude stars of HD type K0. HD 65195, a system containing a giant star, has the unusually short period of 38 days. HD 68874 has a remarkably large mass function; but no secondary star is seen in the radial-velocity traces or in a classification-dispersion spectrogram, although some abnormality exists in the object's narrow-band photometric properties. A possible resolution of the difficulty is that the secondary may itself be a close binary, so HD 68874 may be a system analogous to HR 6497 and d Serpentis.
