couleur grise résultant du blanc et du noir ressort de mieux en

ogy of Audition. 
_ The immediate consideration of the laws we have established 
gives the most convincing confirmation of Helmholtz’s ideas of 
the high differentiation in the dynamic constitution, or mechan- 
ism of the ear. The very fact of the ear’s power to effect a 
ism, so differently affected in its different 7 by sounds of 
ivined this even 
ments, and as it is evidently altogether independent of the 
mode of production of sound on each instrument, we have to 
conclude that we have here to do with a difficulty which resides 
that the Here is a phenomenon which neatly proves 
that the vibrations of the mobile parts of the ear for bass 
sounds are not ‘damped’ sufficiently, or quickly enough, to 
saree two sounds to succeed each other so rapidly without 
“This fact proves, besides, that there should be in the ear dif- 
Jerent parts which are set in vibration by sounds of different height,
