that in the territories of Quito, and Nuevo Reyno, and in certain parts of Asia and Africa, crocodiles have shown the utmost fury towards men, when they are daily tormented, taken, and slain, by the inhabitants, who feed regularly upon their flesh. Different nations make use of different artifices in hunting and killing crocodiles. Some go upon the river in boats, and throw into the water a piece of wood, to which flesh or fish is fastened with a long rope. The crocodiles swallow the wood along with the flesh, but as it is crossed in their jaws, are unable to throw it up, and being dragged to the bank by means of the rope, are presently killed. Others take a long, sharp, pointed piece of timber, and when the crocodile approaches thrust it deep into the animal's jaws, by which means it is killed without danger. The Abipones generally pierce those crocodiles with a spear which they find lying basking in the sun quite stiffened with cold. An arrow, though extremely strong, unless it touch the neck of the crocodile, where the skin is softer, always proves a weak and precarious instrument of death. The same may be said of bullets. Though crocodiles are perfectly harmless to mankind in Paraguay, they are in like proportion destructive to fishes, which are either consumed or put to flight by them. They are useful in medicine. Wounds inflicted by a crocodile are happily cured by being smeared with the fat of the same animal. One of their intestines, when dried and reduced to powder, is a remedy for the pain of the stone. Little stones, like common flint, found in the stomach of the crocodile, are said to be very efficacious in curing quartan agues, and stone in the kidneys, if reduced to powder and drunk. I have observed elsewhere that envenomed wounds of snakes are both healed and prevented by crocodiles' teeth, and shall tell you many things relative to the use of this remedy, in their proper place. If I have been too prolix in my remarks on this prince of amphibious animals, the reader will excuse it, for I shall aim at brevity in treating of more ignoble creatures. THE AGUARÀ, OR WATER-DOG.
