From: Webster's Revised Unabridged Dictionary (1913)

 Tel·e·graph·o·scope n.  An instrument for telegraphically transmitting a picture and reproducing its image as a positive or negative.  The transmitter includes a camera obscura and a row of minute selenium cells.  The receiver includes an oscillograph, relay, equilibrator, and an induction coil the sparks from which perforate a paper with tiny holes that form the image.  It is now (1999) obsolete, having been replaced by telefax and internet transmission of images.
