A Telephonic Exchange.

There seems no reason to doubt,” the “ PailMaJJ Gazette ” says, “ that London will shortly be supplied with a telephonic exchange, and that peo.pl© grill be able to communicate with each other by their voices ©a pajsily over a distance of some miles as if they were h> flip same room. A subscriber who has a yire, with © receiver and a transmitter in bis house signifies his wish to the central office to b,e put in communication with another subscriber. Immediately the two wires are connected, and a conversation can be carried on without tj|o slightest difficulty. A complete exhibition of the apparatus was given the other day, and the convepisne© which the invention will be to men of business w& a made abundantly clear. Directions could be given without the slightest possibility pf firmy, and the tones of the voice were conveyed yith .complete accuracy. Many a mail who would riot b.e troubled to work or watch an ordinary telegraph apparatus, will at once make use of the telphone for the ordinary purpose of his daily business. Still more remarkable, howe* et, than the communication thus established was the experiment made with n telephone upon a meclmPfiCid type-setter. By means of speaking through thg telephone a complete series of sentences Mp }h type >“ a composing stick. The only drawback to the telephone exshang© itself appears to be that we are threatened with a bomber more wires running from house to house. These are dangerous, not so much to the householders as to passers-by ; and Although the Dean and chapter of St. Paul’s have, it spanis, made no objection to the ng© of the cathedral as a station, pome steps ought to be taken to see that the wires are securely fastened.
