how prodigious must be the development of the sesthetic 

 sense in these species, in order that it may take account of 

 every Httle betterment which leads towards more perfect 

 beauty. As it will take the generations of aesthetes many 

 generations before they are able to "live up to" the level 

 of their culture which is attained by the peacock's tail, it is 

 not unreasonable for us to hold that in the appreciation of

 difference in the pleasure-giving changes of the day or the 

 weather. They rejoice in the coming of each morning; they 

 are sorrowful with the advent of each evening. They echo
