ON THE EXACT IMITATION THEORY. 11 



closer resemblance to nature has a smaller value 

 *than the last, and that, if the main characteristics 

 of the natural are expressed in the artificial, the 

 latter may be considered a good one. Let us 

 take an example : The medium Olive Dun has 

 a body olive green down the back, olive yellow 

 underneath, and with sides ribbed with both 

 colours ; but since the sides are most exposed to 

 the fish's view, their impression on the eye must 

 so predominate as to make it sufficient that the 

 whole body of the artificial should uniformly 

 resemble them.
