"The method of F. Kohlrausch for the determination of the ratio of the heat conductivity [upside down gamma], to the electrical conductivity k of a substance is of practical value as well as of theoretical interest. Of practical value because there may be obtained from it - with much great ease than by direct methods - the heat conductivity which has immediate applications, not only to the design and construction of furnaces, but to various other matters of such import; of theoretical interest to the physicist, because of the Wiedmann-Franz and its consequent relation to the electron theory; to the mathematician, because of the applicability of the Fourier analysis" – Introduction, p. 1.
