the back. This Crocodile is less ferocious than some of 
the other kinds, and when taken young, it may be tamed. 
It is common in Senegal and other parts of Africa, as 
well as in the Nile. 
The double-crested Crocodile of the Ganges is very fero- 
cious; and when gorged with prey, it will bury what it 
cannot eat in the mud. This, however, is done occasion-

The Crocodile of South America is more flexible in its 
body than the other kinds : the female lays her eggs in 
the sand, but when the young are hatched, and she hears
