This leads to the startling suggestion that what is force on this plane may be substantial on another, and we are now seeing, as a result of the study of the _x_-rays, and the [alpha], [beta], [gamma] rays of radium, all of which can pass through ordinary matter with ease, a revival of the ancient and supposedly extinct theory held by Newton, and others before him, that light is a body composed of corpuscles--whatever they may be. Professor Bragg, of the Leeds University (England), has been investigating the problem with great care, with the result that he has come to the conclusion, as he announced to the members of the Royal Institution, London, the other day, that the "gamma" rays of radium and the _x_-rays are corpuscular, and not merely pulsations in the ether. He thinks they are probably electrons, corpuscles of negative electricity which have assumed a cloak of darkness in the form of sufficient positive electricity to neutralize them. It seems also that as ultra-violet light, which exists in ordinary sunlight, possesses many of the properties of the above rays, Professor Bragg may not be far wrong in his further suggestion that it also may be corpuscular in its nature. He asked, very pertinently, that if this light be corpuscular, why may not all other forms of light be so? When we recollect that the "corpuscles" themselves are a purely metaphysical concept, it is plain that science is moving rapidly towards a very different and far more reasonable and Theosophical idea of the universe than the materialistic one. _Vivat!_ THE BRIDGES OF PARIS: by G. K. The Bridges of Paris are of distinctive interest and their very names suggest in part the fascinating panorama of French history and legend--Tolbiac, Bercy, Austerlitz, Sully, Marie and Louis Philippe, Notre Dame, Pont San Michel, Solferino, La Concorde, Alma, Iéna, Passy, etc. The Seine flows for seven miles through the city and is at its widest (nearly 1000 feet) at the extremity of the island called La Cité. This island communicates with the right bank of the Seine by the bridges of Notre Dame and Au Change. The latter, as is evident from the familiar device sculptured above the piers (see illustration), was built by the first Napoleon. [Illustration: Lomaland Photo. and Engraving Dept. PARIS: THE PONT AU CHANGE AND THE PALAIS DE JUSTICE] [Illustration: Lomaland Photo. and Engraving Dept. PARIS AND THE SEINE] The Palais de Justice is located in La Cité and the Greek façade by Duc is considered one of the finest examples of this style in modern architecture.
