DUPLEX TELEGRAPHY.
From the last number of the Telegraphic Journal it would apjiear that the telegraph officials of the Post-office have succeeded in applying the duplex method to the Wheatstone automatic instruments, the practicability and im* portauce of which 'was pointed out in an- article on " Telegraphic Progress," in the Times of Nov. 22nd last. The trial'would appear to have been made at the recent Epsom meeting, when there were of course a great many telegrams of all kiuds to be received and despatched; and it is stated that id one hour 219 messages were sent.; in one direction, and 139 in the other—--358 in all ; more could have been sent in the latter case had there been more to send ; and from this it would seem not unreasonable to hope that the speed of the Wheatstone system may one day reach, or even exceed, 400 messages an hour. The messages are said to have heeu of the ordinary kind, and of the ordinary length, and the number transmitted is believed to have been the largest ever sent oh one wire in the same time.
