466 Sub a 4 instance, obtained from the energy of the disturbances or effects transmitted from a distance, but from an independent source. Expressed generally the present method. consists in using, under control of the effects or disturbances transmitted through the natural media, stored energy derived from an independent source for operating a receiving device. A great variety of disturbances, produced either by suitably constructed transmitters or by natural causes, are at present known to be propagated through the natural media, and there are also a variety of means or devices enabling energy to be stored, and, in view of this, I wish to say that I consider the utilization of any such disturbances and the employment of any of these means as within the scope of my present invention so long as the use of the general method hereinbefore stated is involved. The best way of carrying out my invention which I at present know is, to store electrical energy obtained from a suitable electrical generator in a condenser and to control the storage or the application of this energy by means of a sensitive device acted upon by the effects or disturbances, and thereby cause the operation of the receiver. 9: In the practical application of this method I usually proceed as follows: At any point where I desire to investigate or to utilize for any purpose, effects or disturbances propagated through the natural media from any kind of source, I provide a suitable generator of electricity, as for example a battery, and a condenser, which I connect to the poles of the generator in series with a sensitive device -6[This page retyped from microfilm for better readability - Ed.]
