THE ANIMAL KINGDOM.

The grown insect differs so widely from the young that 

 one cannot in the least recognize the one in the other. The 

 ScarabaeuSj or sacred beetle, with its emerald elytra, which 

 was worshipped in ancient Egypt, does not in the least re- 

 semble the hideous subterranean worm which produces it ; 

 a singular metamorphosis, in which, according to M. Goury, 

 the nations on the banks of the Nile beheld the symbol of 

 the transmigration of souls.

 1. The Larva or Caterpillar. 2. The Nymph or Chrysalis. 3. The Perfect Insect or Imago. 



Aristotle, whose genius has thrown such a brilliant light 

 upon the history of animals, had only a suspicion of their 



ferent genera. The nymph of the dragon-fly has been taken by Eondelet for the 

 aquatic Cygala ; by Monffet for the water-flea or grasshopper ; and by Redi for 

 the aquatic scorpion. The three different states of certain Acridia have also been 

 described as three different insects. Lesser, Thc'ologie des Insectes. Trad, de
