 a prominent mark of distinction between butterflies and 

 moths. 



Very graceful appendages are these waving antennae,

 still, their exact office or function is unknown, notwith- 

 standing that many guesses and experiments have been 

 made with a view of settling that question. 



Investigators have perhaps erred, by assuming at the

 have had of the faculty of sight, had all the world been 

 born blind. 



For example ; if you breed from the chrysalis a 

 female Kentish Glory Moth, and then immediately 

 take her — in a closed box, mind — out into her native 

 woods, within a short space of time an actual crowd of
