    IN 1869 Lord Rayleigh commenced the long series of papers and memoirs in Mixed Mathematics, which the Council had in view in making the award, with an article (Philosophical Magazine, vol. xxxviii., third series) “On some Electro-magnetic Phenomena considered in connexion with the Dynamical Theory,” founded on Clerk-Maxwell's celebrated “Dynamical Theory of the Electro-magnetic Field” (Phil. Trans., 1865), the subject being “Examples of Electro-magnetic Problems illustrated by comparison with their Mechanical Analogues.” I may add, to complete the key-note, thus struck, of Lord Rayleigh's scientific career, that these theoretical results were followed up in the next year by an account of “An Electro-magnetic Experiment,” viz. the magnetizing effect of an induced current as dependent on the self- and mutual inductions of the circuits—an early instance of the author's practice of making theory and experiment, or concrete example, illustrate one another. This combination of experimental with mathematical skill and fertility of resource has been conspicuous in Lord Rayleigh's later memoirs on the “Determination of the Ohm and B.A. Unit of Resistance in Absolute Measure” (Roy. Soc. Proa, vol. xxxiv., and Phil. Trans., vol. clxxiii., 1882.)
