The natives eat the crocodile, but to us the idea of tasting the musky-scented, fishy-looking flesh carried the idea of cannibalism.

Humboldt remarks, that in South America the alligators of some rivers are more dangerous than in others.
Alligators differ from crocodiles in the fourth or canine tooth going into a hole or socket in the upper jaw, while in the crocodile it fits into a notch.

The forefoot of the crocodile has five toes not webbed, the hindfoot has four toes which are webbed; in the alligator the web is altogether wanting.

They are so much alike that they would no doubt breed together.
One of the crocodiles which was shot had a piece snapped off the end of his tail, another had lost a forefoot in fighting; we saw actual leeches between the teeth, such as are mentioned by Herodotus, but we never witnessed the plover picking them out.

Their greater fierceness in one part of the country than another is doubtless owing to a scarcity of fish; in fact, Captain Tuckey says, of that part of the Congo, mentioned above, "There are no fish here but catfish," and we found that the lake crocodiles, living in clear water, and with plenty of fish, scarcely ever attacked man.
