Infront of the membrane was placed a horizontalcylinder, which was wrapped with a sheet ofpaper, covered with a thin layer of lampblack,against which the bristle rested lightly. Anysound vibrations entering the ellipsoid weretransmitted by the membrane to the stylus,which, when the cylinder was made to revolve,and to advance slowly, descril)cd on the lamp-black surface a zig-zag line which was thus prac-tically a phonographic record of whatever vibra-tions had been produced.
