The existence of a galactic magnetic field is presupposed by theories describing the polarization of starlight, the emission of galactic radio noise, and the behavior of cosmic rays. An attempt to measure the field by measuring the Zeeman splitting of the 21-cm hydrogen line is described. The line-of-sight component of the galactic magnetic field causes a splitting of the radiation into left-hand and righthand circulatory polarized waves with a difference in frequency of 2.8 cps/10/sup -6/ gauss.
