Music on a Stringless Violin The new discovery which caused such an enormous sensation at the Oersted meeting fills a great space in the Danish Press, says a Copenhagen correspondent. The two young scientists, both of whom are about 30, have discovered a phenomenon reminding one of electromagnetism, but with this difference, that by the new discovery it is possible by a relatively small voitage to create an attraction by a hitherto unknown force between two slabs touching each other. By placing a lithographic stone against a metal plate and passing an infinitesimally small current through them, it is possible to make the two bodies cohere, so that they can hardly be torn asunder. This discovery has been utilized for the telephone. Thus words spoken in one part of a building were heard clearly and distinctly by an audi lence in another part. stringless violin was then placed on the apparatus, and music played into another apparatus at the other end of the building was heard as if the player were in the lecture room itself. Speech was transmitted in the same way quite istinetly with the speakers' own intonation. This experiment cat ed a tremendous sensation. Finally there was a demonstration on an apparatus for taking wireless messages, which with the greatest accuracy wrote down 600 words a minute, The telegram was not stopped in the receiver, but was sent on simultaneously, and this makes the capacity of stations 20 times what it now is. At wireless stations it is no longer necessary to maintain a watch, as the apparatus is able to call up the operator.
A Danish expert on electromagnetism. Professor Larsen, says that the discovery is undoubtedly enoch-making. offering quite boundless possibilities. He says it is the finest way in which Danish science can celebrate the Oersted centenary. The practical results which will be forthcoming when the scientists of the world set to work will revolutionize every sphere where electricity is employed. A report on the discovery will be published in the scientific reviews of the world in the near future.
