On the “Electric Telescope”: “I have read with interest the letter (No. 15374) of Mr Redmond in your last number. Though not an electrician, the possibility of transmitting images – built up, as it were, of a number of points – by means of a number of circuits, each containing selenium at the receiving end, as suggested by your correspondent, occurred to myself a short time since.” English Mechanic and World of Science no726, 21 February 1879 [link].
