The theories for non-polar substances, and the previous experimental studies of the magnetic double refraction of liquid mixtures are reviewed. Measurements are given for benzene in the following solvents: carbon tetrachloride, cyclohexane, pentane, hexane, heptane, and dodecane. The value of the Cotton-Mouton constant of dodecane is given for the first time, C m =-2·81 × 10-14, and compared with the values for other paraffins. The results are discussed in relation to the theories of Snellman and Ramanadham. Complete agreement is found with Ramanadham's theory for the simple case of benzene in carbon tetrachloride. The values also support Snellman's theory, but more data are required for a closer check, especially values for vapours.
