Page 4 - I have long held an opinion, almost amounting to conviction, in common I believe with many other lovers of natural knowledge, that the various forms under which the forces of matter are made manifest have one common origin; or, in other words, are so directly related and mutually dependent, that they are convertible, as it were, one into another, and possess equivalents of power in their action.
Page 6 - ... the lamp-flame became visible, and continued so as long as the arrangement continued magnetic. On stopping the electric current, and so causing the magnetic force to cease, the light instantly disappeared; these phenomena could be renewed at pleasure, at any instant of time, and upon any occasion, showing a perfect dependence of cause and effect.
Page 94 - This work is the lineal descendant of the " Manual of Inorganic Chemistry" of Eliot and Storer, and the "Elementary Manual of Chemistry " of Eliot, Storer and Nichols. It is in fact the last named book thoroughly revised, rewritten and enlarged to represent the present condition of chemical knowledge and to meet the demands of American teachers for a class book on Chemistry, at once scientific in statement and clear in method. The purpose of the book is to facilitate the study and teaching of Chemistry...
Page 14 - The magnetic forces do not act on the ray of light directly and without the intervention of matter, but through the mediation of the substance in which they and the ray have a simultaneous existence; the substances and the forces giving to and receiving from each other the power of acting on the light.
Page 73 - Kelvin (now 40 years ago*) gave the solution of the following problem : — Let the two ends of a cord of any length be attached to two points at the ends of a horizontal arm made to rotate round a vertical axis through its middle point at a constant angular velocity, and let a second cord bearing a material point be attached to the middle of the first cord. .The motion now is investigated in the case when the point is infinitely little disturbed from its position of equilibrium.
Page 3 - illumination of the lines of magnetic force" has been understood to imply that I had rendered them luminous. This was not within my thought. I intended to express that the line of magnetic force was illuminated as the earth is illuminated by the sun, or the spider's web illuminated by the astronomer's lamp. Employing a ray of light, we can tell, by the eye, the direction of the magnetic lines through a body; and by the alteration of the ray and its optical effect on the eye, can see the course of...
Page 14 - That magnetic force acts upon the ray of light always with the same character of manner and in the same direction, independent of the different varieties of substance, or their states of solid or liquid, or their specific rotative force...
Page 15 - ... as yet described, and is further strengthened by the fact that, leaving the loadstone or the electric current, which by inductive action is rendering a piece of iron, nickel, or cobalt magnetic, perfectly unchanged, a mere change of temperature will take from these bodies their extra power, and make them pass into the common class of diamagnetics. 2230. The present is, I believe, the first time that the molecular condition of a body, required to produce the circular polarization of light, has...
Page 3 - Hue of magnetic or electric force, or even of a line of gravitating force, except as it and they are manifest in and by substances ; I believe that, in the experiments I describe in the paper, light has been magnetically affected, ie, that that which is magnetic in the forces of matter has been affected, and in turn has affected that which is truly magnetic in the force of light.
