- The values are for the Ha line: The empirical formula (n2-I)/(n2-1-o 4)d apparently gives more constant values with change of temperature than the LorenzLorentz form.

- In any region of velocity where it is possible to represent p with sufficient accuracy by an empirical formula composed of a single power of v, say v m, the integration can be effected which replaces the summation in (to), (16), and (24); and from an analysis of the Krupp experiments Colonel Zabudski found the most appropriate index m in a region of velocity as given in the following table, and the corresponding value of gp, denoted by f (v)or v m lk or its equivalent Cr, where r is the retardation.

- Two acids corresponding to this empirical formula are known - namely ethylene succinic acid, H0 2 C CH 2 CH 2 CO 2 H and ethylidene succinic acid CH3 CH(C02H)2.
- This is the equation to a parabola, and is equivalent to the empirical formula of Avenarius, with this difference, that in Tait's formula the constants have all a simple and direct interpretation in relation to the theory.
