Virtues of the Autiphone.
Yankee clerk in one of the departments has invented a contrivance called the autiphone. The thing consists of a little diaphragm that can be put in the ear, where it is not visible or unpleasant, and it shuts out all sounds except the words of a person conversing close to one wearing the 'phones. The noise of wagons, ice cream men and the deviled crab man are wholly shut out. The diaphragm operates like the corundum crystals that polarize light, letting some rays pass and shutting out others.—New York Sun.
