372 a a' Room 91. In the matter of the application of Nikola Tesla, No. 729,812, filed September 8, 1899, Apparatus for Utiliizing Effects Transmitted through the Natural Media. Hon. Commissioner of Patents, Sir:- October 20, 1899. In the matter of the application above named we now amend as follows: On page 1 of the specification, line 2 of the second paragraph, after the date "June 24, 1899" insert: "Serial number 721,790". Cancel from the 2nd line from the bottom of page 1, to the 24th line on page 5, inclusive, and insert as follows: "Several ways or methods of transmitting electrical disturbances through the natural media and utilizing them to operate distant receivers are now known, and 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. -1[This page retyped from microfilm for better readability - Ed.]
