TT.’oliler’ observed that the metal could be quickly brouglit into solutioii n.hen the current acted upon it in the presence of an alkali. I t is altogether probable that, under such conditions. its separation from the other metals of the group could be quite readily brought about, but lack of material will, at least for the present, prevent any such iiir.estigation. 0.UlOO
