Enquires where Parsons obtained the papers from as he wishes to give a paper on the subject before the Royal Society of Arts and is collecting historical and up to date information on the subject for the purpose. Informs that the cathode ray system he believed he was the first to originate is being experimented with in Paris by Monsieur Dauvillier and Monsieur Holweck, whose laboratories he visited last year. Comments on the advantages of the cathode ray system. Notices that in the paper sent to him, the pictures consist of only 2, 500 elements, whereas for Television, except of the most crude and rudimentary kind, the number of elements must be at least 100, 000 or more. Wishes to generally discuss the subject with Parsons. |
