VIBRATIONS PRODUCING COLORS.

TABLE OF VIBRATIONS IN CHROMATIC SCALE OF COLORS. 



The slowest vibrations of the ether are first 

 recognized as a red color, which corresponds with 

 the slowest vibrations of the bass note of the musi- 

 cal gamut ; and the quickest vibrations appear as 

 the violet hue, which corresponds with the high- 

 est musical note audible : for, as previously stated, 

 when the vibrations of the air exceed a certain 

 limit, the tympanum of the ear has not time to 

 recoil before a succeeding impulse arrives, and 

 it remains motionless. So the retina of the 

 eye ceases to vibrate beyond the limit of the vio- 

 let, and darkness follows. Darkness and silence 

 are, therefore, equivalents of the cessation of vibra- 

 tions of the retina and tympanum respectively ; as 

 cold is, also, of the cessation of vibrations through 

 the fibres of the nerves of feeling.
