To conclude — for many excellent suggestions, and the 

 kind and continued intei'est which he has taken in the 

 progress of this little Essay, I embrace this opportunity 

 of publicly acknowledging my sincere thanks to my esteemed 

 friend, Mr. Edward Doubleday ; feeling, however, that such 

 thanks are a very inadequate return for his invaluable 

 assistance.
