 tion of the Ear, not only its importance, but by analogy 

 that the mind is indebted to Sensatory Apparatus for a 

 knowledge of danger, of philosophy, and of all the en- 

 joyments the External World is adapted to produce. 



142. THE PHYSICAL MEANS BY WHICH SUCH GRAND 

 RESULTS ARE PRODUCED are wonderfully simple and few. 

 Waves of air, colors and direction of light, odorous 

 properties, savory properties, temperatures and presence 

 of objects, and density of objects, requiring only a cor-
