Theoretically, by introduciiig complex values for thedielectric constants, oiie easily finds that the coefficient ofabsorption x, like the speed of transmission, constitutes anunambiguous function of the oscillatory direction, and thatfor a uniaxial crystal, x, as a function of g, is indicated bythe equation — = A^ cos^g + B^ sin^g A and B being two constants.

The above stated theoretical conclusions, which entirelycoincide with previously reported experimental results, areperfectly independent of the physical nature of absorption,on which depends only the size of the ellipse axes, consideredas functions of the wave-length. översikt av Finska Vetenskaps-Societetens För-handlingar.
