PREFACE. 



our regret is less on account of the unsuitableness of these papers 

 to this Magazine (because we are convinced that in the end they 

 will do good), than because of the space which they occupy 

 among the " Original Communications." This circumstance has 

 determined us to arrange all future controversy (and we trust we 

 shall henceforth have very little) under a distinct head, and imme- 

 diately before " Retrospective Criticism ;" where, being in a small 

 type, it will occupy much less room, and may be passed over by 

 those who do not take an interest in the subjects discussed.
