DEDICATION. 



\**? 



THIS slight introduction to one of Nature's inexhaustible 

 sources of wonder and delight, I inscribe to three Sisters, 

 my affectionate friends ; who, by their cultivated minds and 

 kind sympathy, have so greatly enhanced my pleasure in 

 the pursuit. 



\ 



Beaconsfield, March 1851.
