CHESTPHONINO.

Tho latest "New York idea" is "chesttelcphfiny." New Yorkers to-day arc rcjoioing in the fact that they havo "discovered a - new .method of 'telephoning and, at the same time, .ail: excellent way of amusing themselves. Instead of placing tho transmitter to the mouth, they put it firmly against the chest and speak in a normal natural tone. Strange, as it is to record, tho listener will hear what is boing said nearly as well as if the mouth were • placed near the transmitter in tho usual way. If tho ' transmitter bo ' placed firmly on the knoe-cap, the speaker will bo heard just as well. Or, again, should the transmitter be placed to tho heel, tho voice can still bo faintly hoard. A London collogo professor of physics, when asked for an explanation, "said-, "Sound waves travel as well in somo eases through substanco as they do through tho air. To provo this, plaeo your ear against tho chost of a speaking person, and tho volume of sound will bo greater than if the ear was placed quito near tho speaker's mouth." To illustrate his point further, ho performed a. rudimentary experiment in "acoustics." Ho placed a inusienl-box insido' a woolloii-liiied case, ' and after having sot the instrument going, lie. closed the lid. Hardly a'sound could bo heard. Placing a wooden'-rod- through an aperture in tho top of thocase. ho pressed it against, tho'musi-cal-box, with the result, that tho "sound waves" were transmitted through the'wood into thi! »ir. and the music could be heard almost as well as if tho box was uncased,
