 out, and even then continues to watch them, as a 

 hen does her chicks, till they have arrived at years, 

 or rather weeks, of discretion. 



No. 1 8 is a portrait of the earwij^ and her 

 numerous family in their first condition. And 

 this picture leads 

 us up to one 

 most interesting 

 point in the ear- 

 wig's develop- 

 ment. You will 

 notice here that 

 the young in- 

 sects closely re- 

 semble their 

 mother in most 

 respects — far 

 more closely 

 than a cater- 

 pillar resembles 

 its butterfly ; 

 they have the 

 same sort of 



head, the same sort of body, the same sort of tail, 

 and the same peculiar pincers ; but they are quite 

 wingless. Now, this brings out in a very clear way 

 their analogies to and their differences from most 

 higher insects ; it enables us to form a distinct 

 idea of the origin of that standing miracle, the 

 metamorphosis of the maggot into the fly and of 

 tiie caterpillar into the butterfly.
