Again, although a ppli cant refers to the work of Hertz, it is not understood whether he operates by the same method or by a different method. Taking the well-known foundation experiment of Hertz, es given for instance in Fleming's Alternate Current Transformer, Vol. 1, page 456, edition of 1896, or the experiment in which electrical waves were set up in the atmosphe re rather than along a wire. ls it to be understood that applicant too sets up electrical waves in the atmosphere and that his receiving instrument absorbs the se waves after the fashion of Hertz's receiving circuit B? Applicant makes no particular point of the frequency of his alternating current. ls it true that hia receiver is tuned to respond to the frequency of the transmitter, or will his receiver absorb the vibrations coming from the transmitter however it be electrically tuned? Manifestly the se points. must be made clear, and although the Examiner might insist upon his rejection on the references until a proper differentiating How do es 141
