man FREQUENCY AND HTGH POTENTIAL CURRENTS 251white light projected against the top of the globe, where itproduces an irregularly outlined phosphorescent patch.When thepoint of the ruby fuses, the phosphorescence becomes very powerful;but as the atoms are projected with much greater speedfrom the surface of the drop, soon the glass gets hot and "tired,"and now only the outer edge of the patch glows. In this manneran intensely phosphorescent, sharply defined line, , correspondingto the outline of the drop, is produced, which spreads slowlyover the globe as the drop gets larger.When the mass beginsto boil, small bubbles and cavities are formed, which cause darkcolored spots to sweep across the globe. The bulb may beturned downward without fear of the drop falling off, as themass possesses considerable viscosity.I may mention here another feature of some interest, whichI believe to have noted in the course of these experiments,though the observations do not amount to a certitude. It appearedthat under the molecular impact caused by the rapidlyalternating potential, the body was fused and maintained in thatstate at a lower temperature in a highly exhausted bulb thanwas the case at normal pressure and application of heat in theordinary way that is, at least, judging from the quantity of thelight emitted. One of the experiments performed may be mentionedhere by way of A illustration. small piece of pumicestone was stuck on a platinum wire, and first melted to it in agas burner. The wire was next placed between two pieces ofcharcoal, and a burner applied, so as to produce an intense heat,sufficient to melt down the pumice stone into a small glass-likebutton. The platinum wire had to be taken of sufficient thickness,to prevent its melting in the fire. While in the charcoalfire, or when held in a burner to get a better idea of the degreeof heat, the button glowed with great brilliancy.The wire withthe button was then mounted in a bulb, and upon exhausting thesame to a high degree, the current was turned on slowly, so as toprevent the cracking of the button. The button was heated tothe point of fusion, and when it melted, it did not, apparently,glow with the same brilliancy as before, and this would indicatea lower temperature. Leaving out of consideration the observer'spossible, and even probable, error, the question is,can a bodyunder these conditions be brought from a solid to a liquid statewith the evolution of less light ?When the potential of a body is rapidly alternated, it is certain
