OF ORNAMENTA TION. 223 



responding position in the area of the first (i.e., 

 the other unbranched) vein of the wing. I do 

 not mean there will be a corresponding spot, for 

 one often occurs in one of these positions and 

 fails in the other ; nor that there may not be sim- 

 ilar spots in all the areas ; but that if there is a 

 brilliant spot in the area of the fourth vein, and 

 only one other similar spot elsewhere, the latter 

 will fall in the area of the first vein. This is the 

 more curious, because I do not discover the same 

 polarity in the repetition of markings in the areas 

 of the branching veins ; here repetition is fre- 

 quent, but it is far more common to find similar 

 markings between the hinder branches of the one 

 and of the other, or between their front branches. 

 Can such a play of plan in ornamentation, 

 affecting more than our mere sense of beauty, 

 awakening indeed in us an intellectual pleasure 

 which does not rest upon the surface of things as 

 a purely sensuous appreciation must do can 

 this be explained as purely for the purposes of 

 the ephemeral creature itself ? If it cannot ; if, 

 for instance, it is of no advantage to the butterfly 

 that its second brilliant ocellus should occur in 

 the area of the first rather than of the second 

 vein, then it cannot have arisen through natural 

 selection, without the guidance of a higher law, 

 which has other ends for beauty than the mere 

 survival of the creature possessing it.
