PRINTED TELEGRAMS.

! DOT AND DASH TO GO. Melbourne, April 3. { Tn the near future the PostmasterGeneral’s Department will be in possession of a high-speed telegraph apparatus which will revolutionise tho methods in vogue in inter-capital trunk lines. This is the Murray multiplex printing telegraph system, the difficulties in connection with tho securing of which have been satisfactorily settled , in London by Mr. Oxenham, secretary j of the department. | A cable message received yesterday i announced that Mr. Oxenham had ordered experimental sets of instru-, ments for high-speed telegraphy. Re-, furring to this matter this morning Mr. C. E. Bright, acting-secretary of the P.M.G.’s department, said that the Murray multiplex system consisted of apparatus which had been developed during the past 15 years for receiving telegrams in printed form. The keyboard, which is similar to that of a typewriter, is operated at the sending end of the line, and perforates i pa pet tape. This tape is passed through a machine which causes electrical currents ,according to an arrange! code, to be transmitted to the receiving station, where the currents operate a machine which prints the t?leg-;’.ms on forms. The multiplex arrangement consists of an apparatus by means of which eight telegrams can bt in transmission on one wire at the same time. Its principle is similar to that ot the Baudot multiplex apparatus, which is in considerable use in Great l.ritain.
