THE WIRELESS TELEPHONE.

According to a contemporary, the inventor of the wireless telephone, Mr Gindell '.Matthews, claims that ho 1 is nearly ready to place his apparatus upon the market. He has been conducting many experiments in London, and has succeeded in satisfying several experts that lie is able to converse with a friend at a distance of over five miles. Recently ho was locked in the strong-room of a commercial house, in the presence of witnesses, and the instrument he had with him conveyed his voice to another wireless telephone, in a distant room of the same building, through steel plates, concrete and brick. Now he is contemplating a test through five miles of solid rock, between Chepstow and Tintern, and he lias succeeded in speaking from Beachley, in Gloucestershire, to New Passage, nearly six miles away, on the other side of the river Severn. The inventor states that his instrument, which can bo made to sell at a handsome profit, for £lO, and costs practically nothing For maintenance, will consist of a box of such modest dimensions and weight that any man could, if he wished, carry one about with him, and thus become his own telephone exchange, able to get into immediate communication with any friend similarly armed. He points out that, apart from private use, his instrument would be of the greatest possible value to Great Britain in time of war, by enabling commanders of columns miles apart to keep constantly in touch with each other, and interchange ideas and information much quicker and more fully than they l could do by wireless telegraphy under war conditions, or by any other means of communication. Some scientific men have expressed the opinion that Mr Matthews’s invention cannot be put into general use, but a few years ago a similar statement was being made with regard to Marconi’s wireless telegraph apparatus. It seems, however, that if many of the new' telephone instruments were sold, the owners woidd be in danger of interfering seriously with one another’s conversations.
