9. Magazine of Natural History. — The principal ento- 

 mological papers that have appeared in this excellent magazine, 

 since our last notice, are by the Rev. W. T. Bree, Mr. Yarrell, 

 and Dr. Johnson. So great a proportion of our readers see 

 this work, and we have already swelled our reviews to so 

 unusual a length, that we must dispense with quotations or 

 criticisms. One of our correspondents alludes to the decrease 

 of matter and wood-cuts; this, however, we trust is merely 

 casual, and we hope to see the original quantity again. We 

 miss Rusticus in the late numbers ; he complained to us, some 

 time since, that Mr. Loudon had " pruned" his epistles with 

 rather too free a hand ; but we hope he has forgiven this, and 

 enriched Mr. Loudon, as he has ourselves, by a twelve-months' 

 store. The July number contained some laughable obser- 

 vations about ourselves, from the pen of Mr. Westwood : we 

 believe we had been reviewing him, but the particulars have 

 escaped our memory.
