(Special to The Review.)

    PHILADELPHIA, PA, February 16.--The telectrophone, a combination of the telephone and talking machine, has been introduced for the first time in this country by Gimbel Bros.' department store and placed at the disposal of all who care to use it.
    Beginning at 9 o'clock, the telectrophone--there are thirty of them in use in the store--gives a concert, flashes news bulletins, recites menus for the benefit of the housewife, and during the afternoon rattles off current market reports and sporting events. Plans are under way to have the telectrophone reproduce grand opera during the evening when the service shall have extended to homes. This is another story, however.
