Pàgina 210 - ... 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.
Pàgina 169 - If, however, the two metals are plunged together into water, the copper, zinc, and water forming a galvanic cell, all remain at one potential, and no charge of electricity is observed on any part of the system.
Pàgina 216 - 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.
Pàgina 210 - Nicol's eye-piece revolving on a horizontal axis, so as to be easily examined by the latter. Between the polarizing mirror and the eye-piece two powerful electromagnetic poles were arranged, being either the poles of a horse-shoe magnet or the contrary poles of two cylinder magnets ; they were separated from each other about two inches in the direction of the line of the ray, and so placed that, if on the same side of the polarized ray, it might pass near them ; or, if on contrary sides, it might...
Pàgina 131 - I propose to distinguish such bodies by calling those onions^ which go to the anode of the decomposing body; and those passing to the cathode, cations^; and when I have occasion to speak of these together, I shall call them ions. Thus, the chloride of lead is an electrolyte, and when electrolyzed evolves the two ions, chlorine and lead, the former being an anion, and the latter a cation.
