A hundred years ago
Mr Edison's patents for the development of the Electric Light have been granted by the Patent Office at Washington, and a Company has been formed to light New York. They have also been filed in London, where there is a rush of electricians to secure protection for their ideas before the American can obtain it. No hint of the nature of Mr Edison's method has appeared, but it is believed that a substitute for the carbon "points," which is nearly indestructible, has already been discovered. We are told also that an electric candle or lamp, which can be carried about, and which gives out a powerful light, has been invented in Paris, and will shortly be seen here. -This must be expensive, as power must be evolved from the destruction of metal, but the haziness of all the discoverers on the question of cost is very notable.
