‎First printing of these papers, the conclusions of which represents an importent step towards televison. (Siers ""Early Televison"", Nos 80, 97 a. 119).""Part I. of this remarkable research deals chiefly with the striking distance in air and different gases under vaying conditions and terminals" battery of 1,800 and 11,000 chloride of silver cells used" reference to O'Shaughnessy's cell. Part II. is an experimental study of the electrical discharge on ""exhausted tubes"". One of the conclusions in Part III. is that ""the electric arc and the stratified discharge in vacuum tubes are modifications of the same phenomenon"". In these researches, a battery of 10,000 chloride of silver cells was used.""(Wheeler Gift No. 3776 b).‎
