plant, or that insect, would be careful to register any 

 other phenomenon that might accidentally occur, which 

 he finds unrecorded. He might otherwise pass it un- 

 heeded, under an impression that it must doubtless 

 have been observed before, and not be a reservation 

 for him. Such manuals might be easily formed, and, 

 if we mistake not, are desiderata. We merely suggest, 



do not presume to dictate, though anxious to reap 

 more benefit from the labours of the student than has 

 been hitherto obtained. 



The reason of the popularity of the " Introduction 

 to Entomology," by Messrs. Kirby and Spence, becomes 

 obvious enough; but these tomes are too ponderous 

 and expensive for the general student, though they are 

 volumes replete with curious facts, and record valu- 

 able phenomena, while the asperities of nomenclature 

 and dogmatism of system are softened down and 

 rendered palatable. Increased evidence is presented 

 in the " Natural History of Insects " of the " Family 

 Library," and others all which have, as it were, taken 

 the public by surprise, and the necromance of novelty, 



just as if the key of knowledge had been taken 

 away, and for the first time restored.
