II. The Bakerian lecture.—On the electro-dynamic properties of metals

The Lecturer gave an exposition of the substance of a paper presented by him to the Society under the above title. The paper consists of five parts, namely:— 1. On the Electric Convection of Heat; 2. On Thermo-electric Inversions; 3. On the Effects of Mechanical Strain and of Magnetization on the Thermo-electric Qualities of Metals; 4. On Methods for comparing and testing Galvanic Resistances, illustrated by Preliminary Experiments on the Effects of Tension and Magnetization on the Electric Conductivity of Metals; 5. On the Effects of Magnetization on the Electric Conductivity of Iron.
