Preliminary values of masses and radii are presented for twelve Algol systems with cooler components of class F or later. The results are new for nine of the systems and are based on measures of the D lines for the faint cooler components. For most of the systems with periods longer than six days the orbits of the hotter components are uncertain because of absorption by non-photospheric matter in the systems. The masses of the hotter components are approximately normal for their spectral types, while the masses of the Roche-lobe filling components range from 0.2 to 1.4 solar masses.
