Abstract

A large metal box fits over the chest, to shut out external sounds. It communicates with the close-fitting ear piece by a rubber tube, which has a side opening about 40 cm. below the ear. This opening enables the sounds to be perceived with much greater exactness, and can be connected if desired with a Marey drum.—Cbl. f. Phys. from C. R. Soc. de Biol., April 25, 1896.
