TO 
De. w. E. LEACH, F.E.S. &c. &c. 
Sir , 
I may justly dedicate the following pages to you , being 
indebted for the most valuable part of their contents to your kindness and 
ibciality, I am happy in thus having it in my power to acknowledge my 
Se ’ lSe °f t,le mam J obligations which I lie under to you : and at the same 
0 t rus t the present work will be the means of aiding you in the very 
o: thy cause in which you are engaged. It is also to be hoped that in 
England, ere long, Entomology will stand on the same ground with Botany, 
Chemistry, or Mineralogy; and that your labours will eventually be as 
culy uppieciatcd in this country as they are now on the Continent. 
I remain , Sir , with the greatest respect, 
Your most obliged and obedient servant, 
Blackfriars Road, 
March laig.
