Commissioner of Patents, Sir:- In the matter of the application above named we now amend as follows:- Cancel from the 5th line from the bottom of page 1 to the 9th line on page 5, inclusive, and insert: "Several ways or methods of transmitting electrical disturbances through the natural media and utilizing them to operate distant receivers are now known, and rate have been applied with more or less success for accomplishing a variety of useful results. One of these ways consists in producing, by a suitable apparatus, rays or radiations, that is, disturbances, which are propagated in straight lines through space, directing them upon a receiving or recording apparatus at a distance, and thereby bringing the latter into action. This method is the oldest and best known, and has been brought particularly into prominence in recent years through the investigations of Heinrich Hertz. Another method consists in passing a current through a circuit, preferably one enclosing a very large area, inducing thereby in a similar circuit situated at a distance, another current, and affecting by the same) in any convenient way, a receiving device. -1[This page retyped from microfilm for better readability - Ed.
