The bimetric theory of gravitation proposed by Rosen (1973), which assumes that there exists at every point of space-time a Riemannian tensor and a flat space-time metric tensor, is tested by application to the binary star PSR 1913 plus 16. The bimetric theory predicts substantial corrections to the stellar masses as deduced from orbital data, but these corrections are shown to be inconsistent with observations of orbital inclination. It is noted that evidence of the applicability of bimetric theory might be obtained when it becomes possible to measure the combined effects of the Doppler shift and the gravitational shift of the system and thereby completely determine its orbital parameters. The bimetric theory would also be supported if dipole gravitational waves from a binary system containing a neutron star, such as PSR 1913 plus 16, were detected.
