TO 



Dr. W. E. leach, F.R.S. &c. 8cc. 



Sin, 



T may justly dedicate iliefullowhig pages to you, being 

 indebted for the ynost valuable part of their contents to your kindness and 

 liberality. I am happy in thus having it in my power to acknowledge my 

 sense of the many obligations which I lie under to you : and at the same, 

 time I trust tlie present work will be the means of aiding you in the very 

 praiseworthy 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 us 

 duly appreciated in this country us they are now on the Continent. 



I remain, Sir, with the greatest respect, 



Your most obliged and obedient servant, 



GEORGE SAMOUELLE.
