A patent was issued to Mr. Nikola Tesla April 18 on the "Art of Transmitting Electrical Energy Through the Natural Mediums." A full account of the patent will be given next week. The claims are on an improvement in the art of transmitting electrical energy to a distance which consists in the establishment of stationary electrical waves in the earth or natural conducting media and operating therefrom one or more receiving devices remote from the source of energy. Electrical oscillations are impressed on the earth or other media to produce the stationary waves, the length of which may be varied and controlled, and their neutral and nodal regions shifted.
