Above the flowers which Frances Freeland always insisted on arranging and very charmingly when she was there over bare shoulders and white shirt-fronts, those words bombed and rebombed. Brown bread, potatoes, margarine, carbohydrates, calorific! They mingled with the creaming sizzle of champagne, with the soft murmur of well-bred deglutition. White bosoms heaved and eyebrows rose at them.
By an extensive series of experiments with the above apparatus the author succeeded in proving that heat is evolved by the coils of the magneto-electrical machine, as well as by any other part of the circuit, in proportion to the resistance to conduction of the wire and the square of the current; the magneto having, under comparable circumstances, the same calorific power as the voltaic electricity.
The less robust conclude the cleansing process with a douche, needle, spray, or shower bath, graduated from warm to cold; and the strong bather, by plunging into a bath of cold water, the object of which is to contract and close the sweat-glands and pores of the skin that have been swelled and opened by the high temperatures of the calorific apartments.
Verdet, who, in lectures which have rightly remained celebrated, defined with remarkable clearness the new theories, said, in 1862: "Electrical phenomena are always accompanied by calorific manifestations, of which the study belongs to the mechanical theory of heat.
Then, in close succession, we find in the solar light obscure calorific rays, the existence of which could admit of being established only with the thermometer, and which may be completely separated from luminous rays by the aid of the prism; we discover, by the aid of terrestrial bodies, that the emission of caloric rays, and consequently the cooling of those bodies, is considerably retarded by the polish of the surfaces; that the colour, the nature, and the thickness of the outer coating of these same surfaces, exercise also a manifest influence upon their emissive power.
