    LECTURE III. ESTABLISHMENT OF THE CONSERVATION OF ENERGY. PAGE Further inquiry into the asserted claims of Mayer. Opinions of Colding and Joule on Mayer's first paper. [Insertion {1884) on the prior claims of Mohr.] Colding's Experiments. Joule's Experiments. Numerical value of the Dynamical Equivalent of Heat. Helmholtz's argument from the Perpetual Motion. Transformation and Dissi- pation of Energy. Illustrative experiments, . . . • 52 LECTURE IV. TRANSFORMATION OF ENERGY. Experimental Illustrations—Heating of wires, and decomposition of water, by a Galvanic current—Electro-magnetic Engine—Rotating Disc—Magneto-electric Machine—Induction-Coil and Geissler Tube —Higher and Lower Forms of Energy. Work transformed wholly into Heat—Only a portion of the Heat can be reconverted into Work. Carnot's Cycle of Operations and his Reversible Cycle. Effect of pressure upon Ice, LECTURE V. TRANSFORMATION OF HEAT INTO WORK. Carnot's Cycle—continued. Watt's Diagram of Energy. The Impossi- bility of the Perpetual Motion is an experimental truth. Conditions of Reversibility. Absolute definition of Temperature. Second Law of Thermodynamics. Absolute zero of temperature, or temperature of a body devoid of heat. Efficiency of the best steam-engine.
