IV DEDICATION. 



devotion of your time and your money to the ad- 

 vancement of Natural Science, and the deep love 

 with which you are evidently inspired for the works 

 of Creation, have impressed me with a strong respect 

 for your character, and singled you out as the in- 

 dividual with whose name I should particularly de- 

 sire to associate this Work. 



I would therefore beg of you to accept of its 

 dedication, and beheve in 



The high consideration and esteem of 



Yours most sincerely, 



THE AUTHOR.
