The Pamphlet Collection of Sir Robert Stout: Volume 85

Chemical Physics.*

Chemical Physics.*

Light:—its production and transmission; Newton's Bays and the Wave Theory. Comparison with Sound. Velocity.—Reflexion. Diffusion. Refraction. Common Optical Instruments. Decomposition of the Solar Bay. The Spectrum. Theory of Colour.

Heat:—its production and transmission.—Expansion of Solids. Expansion of Liquids; Thermometers; the Centigrade as a standard graduation. Expansion of Gases; Ventilation. Convection; Conduction. Radiation; Reflexion and Refraction of Heat Rays; Diathermancy.—Changes in the condition of matter produced by the addition and subtraction of Heat. Latent Heat. Specific Heat. Phenomena connected with Ice, its production by Evaporation. Leading facts connected with Steam, and its uses as a motive power, and for heating, cleansing, &c.

Magnetism:—The Lodestone; artificial Magnets; polarity; attraction and repulsion. The Mariner's Compass. Declination and Inclination.

Frictional Electricity:—Positive and Negative; mutual action. Production; Electrical Machines. Storage; the Leyden Jar. Action of Points; Lightning Conductors. Electrometers.

Voltaic Electricity:—The dry Voltaic Pile. The Galvanic Cell; its multiplication forming a Battery. Differences page 44 between Frictional or Static, and Voltaic or Dynamic Electricity. Properties and effects of the latter:—production of Heat (Thermo-Electricity); Chemical action (Electro-Metallurgy).—Electro-Magnetism and Magneto-Electricity:—Galvanometers. The Needle, the Morse, and other Telegraphs. The Telephone.—The Electric Light.

Though the syllabic materials given are, as stated, mainly intended for the first Period, it has been found convenient to place here the whole of the subjects connected with Electricity, albeit many of them will be best taught in the second Period, and some need only be gone into in detail by those youths who in the third Period, are specializing their studies, with a view to becoming Electrical Engineers.

* Though the term "Chemical Physics" has been objected to by some scientists, it is retained here on the authority of eminent authors as designating an intermediary position between Mechanical Physics and Chemistry.
