hundreds of species, so that it is a wide subject 

 and might be indefinitely extended.

With a magnifying glass one may see the two 

 kinds of eyes with which bees are furnished. 

 The two large eyes with hundreds of facets 

 which we can easily see, are supposed to be for 

 discerning objects near at hand. Then on the top 

 of the bee's head are three little specks of eyes 

 called " ocelli," placed in a triangle ; these are 

 believed to be for long vision, to enable the bee 

 to guide its flight in the air. 



A small lens is an essential thing to carry 

 about with us, revealing a whole world of interest 

 and beauty, which does not come within the range 

 of our ordinary vision.
