PERPETUAL MOTION.

Several people have had a shot at making "something that would go on for ever, like Tennyson's brook. And these have not all been cranks. A mechanician, for, instance, made a top, which was balanced on diamond tips and spun, in a vacuum, which ran for twelve month? , A Swiss watchmaker has lately Invented £n. electric watch which will go for fifteen" -iSars without requiring to be. re-wound, A watch and clock maker of burton has in his possession an electric clock of his own making which has already gone twelve years, and has never, failed to record the time during that period, although It has never toeen re-wound. He claims that the mechanism will las,t fifty .years, and that he would not be surprised if the clock ran uninterruptedly for a century. Of course; the possibilities of radioactivity are to-day only dimly known, but they may yet revolutionise all our notions of motion and energy, and put even electricity out of court
