NEW PHASE OF TELEGRAPHIC SCIENCE.

(Canadian Paper.) ' »!&; ; !nomber>of jgentlemon interested; in scientific matters recently assembled at^the pfficeof the Dominion Telegraph) Company to witness some, very wonderful experiments on_an apparatus which ha| K been invented, by, Mr-, A.. Graham Be,U,ason : 6f^Pr.ofeßsbr: ; A.'']sf.'.Bejl, of j Tut elan r heights. : This gentleman claims to be able to transmit musical sounds over a' telegraph wire. A per-son-Hinging or speaking for example at one .eh^dofrthe wire, every note or word^willibe idistioctly heard at the other end— not only the words would be heard, but the tones of the voioe also would be readily recognised by any one who had heard them before. Anther ; very important improvement which, j Bell .claims to put into use, may r i>e^ described, as follows: — A'man wishing to sefccl a message to Hamilton, fo^instaoce, writes it on shellac. paper; . It isreceived by a boy who puts into ja.,? machine toe; the purpose. The message is received in Hamilton by another boy' who brings;, it forth from a similar machine, 'copied upon a piece of shellac paper in telegraphic impressions, or written like copper-plate. Pictures drawn in shellac can also be sent and r«jo"eived. in'' 'the - same: way. It this " system can be';,put into use and worked effectually, it will, do away with telegraph operators altogether. But the ntOSt) important feature which Mr Bell' claims is that he can transmit thirty or more messages over a single telegraphic Wjiije ,a / t,r.one and the same time. The. way he. proposes to do this is/as follows: Opj a, i wire running from say Brantford to Toronto, Mr -Bell would place thirty - or more instruments at Brantford office. A x fi°tiiese instruments i,'to be tuned' to L different .pitches. .'. A . corresponding number 'of instruments to be placed in Toronto. office,. each of the instruments tuned in unison with the corresponding instruments at Brantford. An operator can,, then transmit a sound on any of these instruments, and none but that at the other; end : of the . line which is in unison, will correspond. Therefore, thirty or forty ' operators can work together on the same wire without in any, way affecting the others. This seems' very wonderful, but Mr Bell claims to be able to put it into practical use, and if he succeeds it will certainly be the,; greatest mechanical discovery made since the invention of the telegraph itself. ;: ; . . V/ Mr,, jß.eli?s explanation and practical' experiments were very satisfactory, and every, person present seemed convinced that he had got hold "of a good thing, ,and one which only required , time to 'bring it into general use; Strange to eay, two other gentlemen, one an ; . named Gray, of Qlj^pago, and. the other a scientist in Copenhagen, have hit upon the same ideas, but it appears Mr Bell was ahead of them both* and got his : discoveries entered in the Patent office, at Washington, ere they appeared ' upon the scet!ei;' I 'He ; is ; backed by Boston aud New "York capitalists. The way in which Mr Bell first got his idea: was by blowing on a single cord inside a piano. He ; "n6'dced that all the other cords; v^Kichi'lw^ were , a fi6? te 3, thereby. A gentlemen present when Mr Bell was explaining, said, that wheri the whole thing Was put in Wjrff king ''shape, a concert given in San Frßncis'cbeouid easily be heerd in New York.
