Theory of the reflection of light near the polarising angle

Supposing the phenomena of light to be due to displacements in a rotational ether, we have the following expressions for the kinetic energy and work function in a transparent isotropic medium:- T= ½ ∫ ρ (ξ2 + η2 + ζ2 )d V, W = ½c 2 ∫ ρμ2 (f 2 +g 2 +h 2 )d V. Hered V denotes an element of volume,ρ is the density, ξηζ the displacement, (fgh ) = 1/ μ2 curl (ξηζ ),c a constant that will prove to be the velocity of light in free ether, whereas μ will be identified with the refractive index. The dynamical equations and boundary conditions are most simply obtained from the Principle of Action, which makes δ ∫ (T - W)dt = 0.
