Page 198 - I should have to put them; for, though the meanings are perhaps right, they are only hypothetical, and may be wrong; and then, through a very imperceptible, but still very dangerous, because continual, influence, they do great injury to science by contracting and limiting the habitual views of those engaged in pursuing it. I propose to distinguish such bodies by calling those anions...
Page 47 - I have rather," he writes in 1831, "been desirous of discovering new facts and new relations dependent on magnetoelectric induction, than of exalting the force of those already obtained, being assured that the latter would find their full development hereafter.
Page 256 - ... the results prove that the quantity of electricity which, being naturally associated with the particles of matter, gives them their combining power, is able, when thrown into a current, to separate those particles from their state of combination; or, in other words, that the electricity which decomposes, and that which is evolved by the decomposition of, a certain quantity of matter, are alike.
Page 145 - I have reason to believe that the statement might be made still more general, and expressed thus : That for a constant quantity of electricity, whatever the decomposing conductor may be, whether water, saline solutions, acids, fused bodies, &c., the amount of electro-chemical action is also a constant quantity, ie, would always be equivalent to a standard chemical effect founded upon ordinary chemical affinity.
Page 196 - In place of the term pole, I propose using that of Electrode*, and I mean thereby that substance, or rather surface, whether of air, water, metal, or any other body, which bounds the extent of the decomposing matter in the direction of the electric current.
Page 291 - His general statement is, that " chemical and electrical attractions were produced by the same cause, acting in one case on particles, in the other on masses, of matter; and that the same property, under different modifications, was the cause of all the phenomena exhibited by different voltaic combinations^..
Page 231 - I at first laid down, namely, that the chemical power of a current of electricity is in direct proportion to the absolute quantity of electricity which passes (377.
Page 197 - Researches, also, to class bodies together according to certain relations derived from their electrical actions ; and wishing to express those relations without at the same time involving the expression of any hypothetical views, I intend using the following names and terms : — Many bodies are decomposed directly by the electric current, their elements being set free ; these I propose to call electrolytes*.
Page 3 - The results which I had by this time obtained with magnets led me to believe that the battery current through one wire, did, in reality, induce a similar current through the other wire, but that it continued for an instant only, and partook more of the nature of the electrical wave passed through from the shock of a common Leyden jar than of the current from a voltaic battery, and therefore might magnetize a steel needle, although it scarcely affected the galvanometer.
Page 366 - I went into the cube and lived in it, and using lighted candles, electrometers, and all other tests of electrical states,. I could not find the least influence upon them, or indication of anything particular given by them, though all the time the outside of the cube was powerfully charged, and large sparks and brushes were darting off from every part of its outer surface.
