Remarks.—This method of acknowledgment has been adopt- 
‘ed, because it is not always practicable to write letters, where 
they might be reasonably expected ; ” still more difficult is it 
to prepare and insert in this Journal, notices of all the books, pamph- 
lets, &c., 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.
