 duction, and of growth, which inspires oxy- 

 gen, and respires carbonic acid, and whose 

 size, specific gravity, solidity, temperature, 

 and power of locomotion, are usually greater 

 as its development is more complex.

 the torpedo and electric eel, which, when 

 touched, give an electric shock resembling 

 the discharge of a Leyden jar.
