XL. An Elementary Theory of the Scattering of Light by 

 Small Dielectric Spheres. By Jakob Kunz *. 



THIS problem was solved a long time ago by Lord 

 Rayleigh f, who used spherical harmonics. In the 

 present analysis it will be shown that the same fundamental 

 result can be obtained by elementary considerations without

the use of spherical harmonics. We consider a plane polarized 

 beam of light, proceeding from above in a vertical direction, 

 Z, so that the plane of polarization is perpendicular to the
