Mr Thomas B. Dixon, a native of the State of Kentucky, has succeeded, asHie recently demonstrated in Boston, in achieving what Edison, Tesla, and other famous electricians have been working at for so many years—viz., the sending of six messages on a single wire. The perfection of this sextupleb system has been what these men have been striving for, but Mr Dixon’s invention is described as being as perfect in its operation as the quadruplex system, which is now in common use. The result has been obtained as the outcome of work which was begun as far back as IS9I, and the first partly successful test was not achieved till two years ago, since which time Mr Dixon has been perfecting his apparatus. He makes the same division as in the quadruplex system—two giying one-third of the current to one set of instruments and two-thirds to the others, the pulsation being so arranged as not to conflict. The test at Boston was over a loop to New end back, and during severs,! minutes’ sending and receiving no breaking or interference was seen. Two sides of the aextuplet. can be used as a quadruplex, and sueff a testT on a loop from Boston to Buffalo and back; and to New Haven and back, a distance o| 1,300 miles, has ’actually been ffiade, thus proving its advantages over the ordinary quadruplex system, the limit of the Suocesful working of which has been from 400 to 600 miles. Edison is said to be the authority' for the statement that one of the great American telegraph companies have sayed

£4,000,000 by the use of' the quadrupled system, and if Mr Dixon’aaextuplet is all that its trial shows a proportionately greater saving in the cost of wire and maintenance will be the result., • ' r : v
