Decomposition of Sounds into their simple Tones. 



THE same resonators (Helmholtz's) which serve for analysis 

 of sounds by means of the ear, are also of use for the visible 

 dissection of sounds by the flames. To this end I construct an 

 apparatus with eight resonators tuned to the harmonic notes of 

 c, each of which is connected with a manometric flame. These 

 eight flames are placed in a slanting line one above the other, 

 and show, in the rotating mirror fixed in the same direction, 

 eight parallel bands of light when in repose, and when in vibra- 

 tion eight waved lines (fig. 11), Of course in this case each 



flame must be perfectly independent of the other, and each flame
