Telegraphoscope
Telegraphoscope Tel`e*graph"o*scope, n. [Gr. th^le far + -graph + -scope.] 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 It is now (1999) obsolete, having been replaced by telefax and internet transmission of images. [Webster 1913 Suppl. +PJC]
