  1. Naturaleza de los Rayos Catódicos (1895) J. J. Thompson There is no other branch of physics which affords us so promising an opportunity of penetrating the secret of electricity."

  2. Naturaleza de los Rayos Catódicos (1895) "This experiment shows that however we twist and deflect the cathode rays by magnetic forces, the negative electrification follows the same path as the rays, and that this negative electrification is indissolubly connected with the cathode rays" J. J. Thompson "I can see no escape from the conclusion that [cathode rays] are charges of negative electricity carried by particles of matter." "we have in the cathode rays matter in a new state, a state in which the subdivision of matter is carried very much further than in the ordinary gaseous state: a state in which all matter... is of one and the same kind; this matter being the substance from which all the chemical elements are built up."
