Heaccordingly subjected the alkaline and earthy bodies, thenreputed to be elementary, to the influence of a powerfulbattery, and found that his supposition was verified. Onplacing a fragment of caustic potash between the poles, itimmediately melted ; from the positive oxygen gas es-caped in bubbles, and from the negative, small metallicglobules, having the appearance of quicksilver, emerged;these were characterized, however, by the singular qual-ities of an intense affinity for oxygen, so that they wouldtake fire on being touched by water, or even ice, andwe
