Thus, as the reader will see, we have in Nature an exact 

 analogy of Art, the Termite queen being confined within her 

 cell exactly as is the hen within the coop. 



Being on the subject of eggs and egg-hatching, we will 

 take another case in which Art has acknowledgedly followed 

 Nature. 



We all know that eggs are developed into life by means of 

 well-regulated heat, and that with birds the general rule is, 

 that the needful heat is supplied by the parent bird, who sits 

 upon them for a certain time, until the young birds make their

Under ordinary circumstances, the aid of the parent bird is
