agitated stream, flowing between broken 

 and sedgy banks, and indistinctly reflect- 

 ing the waving foliage that hangs over it, 

 rough; because we know, from habitual 

 observation, that its impression on the 

 eye is produced by uneven surfaces ; at the 

 same time that the impression itself is all 

 of softness and harmony ; and analogous 

 to what the most grateful and nicely varied 

 smoothness would be to the touch. This 

 is the case with all smooth animals, whose 

 forms being determined by marked outlines, 

 ■and the surfaces of whose skins producing 

 strong reflections of light, have an effect 

 on the eye corresponding to what irritating 

 roughness has upon the touch; while the 

 coats of animals which are rough and 

 shaggy, by partly absorbing the light, and 

 partly softening it by a mixture of tender 

 shadows, and thus connecting and blend- 

 ing it with that which proceeds from sur- 

 rounding objects, produce an effect on the 

 eye similar to that which an undulated and 

 gently varied smoothness affords to the 

 touch. The same analogy prevails between
