Abstract
A PAPER on telegraphic typesetting by H. H. Harrison read and discussed before the Institution of Electrical Engineers appears in the Journal of the Institution of October. In the discussion, Mr. D. Murray pointed out that the paper is valuable because it reminds us that, in addition to strong stream and weak stream technique, there are controlling electro-mechanisms of the most remarkable character, correctly described as electrical typewriter-keyboard machines, of great complexity and beauty. The teletype, one of these keyboard machines, of which the fundamental characteristic is the transmission of intelligence by semi-mechanical machines (telegraph class of mechanisms), is in wide use in the form of a telegraph exchange, analogous to a telephone exchange, covering the whole of the territory of the United States, with about 15,000 subscribers. Considerable progress was being made in this direction in Great Britain also, and plans were being considered for spreading the exchange all over Europe. Unfortunately, this development has been interrupted by the War.
