274 THE FACT OF BEAUTY 



that they never fail to set up pleasant changes in the human 

 eye. 



The third component of the beautiful in animals is move- 

 ment. Just as we enjoy watching a waterfall, a fountain, 

 the waves, or even the dance of motes in the sunlit air, so 

 we are delighted with the jellyfishes throbbing in the tide, 

 the flotilla of sepias all keeping time as they swim, the flying- 

 fishes rising before the prow of the steamer like locusts 

 before us as we walk in the meadow, the porpoises gam-

 it moves slowly a wave, but without wind ! a current, but 

 with no fall ! all the body moving at the same instant, yet 

 some of it to one side, some to another, or some forward and 

 the rest of the coil backwards, but all with the same calm

 location in its coils. Startle it the winding stream will be- 

 come a twisted arrow; the wave of poisoned life will lash 

 through the grass like a cast lance." 



Spoil an animal say by fattening and the beauty of 

 its movements vanishes, we have the waddling duck and
