I A’ new form of incandescent lamp* in which' vaporised petroleum spirits is used, has boen devised. The principle of tho invention is a petroleum spirit' vessel placed at a higher level than the burner.. From this vessel the gasoline gravitates through a tube to a control valve, which regulates the tflo.wi o£ the volatile liquid, into a generator, where it is vaporised through toeing heated by a separate flame. The gas then passes through a needle valve receives its correct proportion of air, and is then ignited ini a burner fitted With an ordinary incandescent mantle. An intense light ig produced. To. start the lamp, the vaporiser has to be heated, and thiSj is accomplished toy the ignition of a little methylated spirit poured over asbestos contained in a tray placed below, the needle valve. The petroleum consumption of the lamp wi th the maximum light is very, economical, one quart of spirit being sufficient to give a light of 150 candle-power for 16 hours. Though the. inherent dangers a trending the use of petroleum are by no means obviated in this) dev,ice, it constitutes an excellent light for outside use, i. Is is :o>nly. the other day, that {Rutherford laid down the theory that radio-active substances are the cause of the earth’s heat, and now we learn on the authority' of Professor Monroe Snyder that ra'diu'm is. the cause of the heat and luminosity, of the celestial bodies. In his ppiuion. variable stars are caused hot by the revolution of ope body about another,, hut by the regular fluctuation of light which is 'duo to periodical outburstsi Ofi radio-acti-vity. The Professor concludes that the s,un! is a variaible star with a period of 11 years, and that the sun spots are one'of the 'demoinsitrations or results of these outbursts of radium emanation's. The problematical rings of light so characteristic of many of the nebulae are accounted for by Professor Snyder by treating them as transition stages, of ra’direactivity.
