 principles of plan and purpose and the intellec- 

 tual quality of perfect execution. We shall love 

 not alone with all our heart, but with all our 

 mind as well. If we judge the world beautiful 

 by the superficial standard of what happens to 

 please our eye, we shall see no more of the world 

 than we do of the new moon. Whole classes of 

 animals and wide regions of the earth's surface 

 must, by this test, be excluded. The only way 

 the batrachians could possibly come in would 

 be by rolling the frogs in bread-crumbs and fry-
