ACKNOWLEDGMENTS TO CORRESPONDENTS, FRIENDS 

 AND STRANGERS. 



Remarks. — This method of acknowledgment has been adopt- 

 ed, because it is not always practicable to write letters, where 

 they might be reasonably expected ; and still more difficult is it 

 to prepare and insert in this Journal, notices of all the books ^nd 

 pamphlets which are kindly presented, even in cases, where such no- 

 tices, critical or commendatory, would be appropriate ; for it is often 

 equally impossible to command the time requisite to frame them, or 

 even to read the works ; still, judicious remarks, from other hands, 

 would usually find both acceptance and insertion. 



In public, it is rarely proper to advert to personal concerns ; to 

 excuse, for instance, any apparent neglect of courtesy, by pleading 

 the unintermitting pressure of labor, and the numerous calls of our 

 fellow-men for information, advice, or assistance, in lines of duty, 

 with which they presume us to be acquainted. 



The apology, implied in this remark, is drawn from me, that I may 

 not seem inattentive to the civilities of many respectable persons, au- 

 thors, editors, publishers, and others, both at home and abroad. It 

 is still my endeavor to reply to all letters which appear to require an 

 answer ; although, as a substitute, many acknowledgments are made 

 in these pages, which may sometimes be, as now, in part, retrospec- 

 tive. — Ed.
