The Indians of Guiana dip their arrows in the juice of the _Woorara_, and the _Curara_, which also occasions rapid death and decomposition of the lungs. Humboldt informs us that the _Curara_ is obtained from the bark of a tree called _Vejuco_ de _Mavacure_; it is inspissated over a slow fire and then mixed with a gum drawn from the _Kiracagnero_. The Abbe Salvador Gilii tells us in his history of America, that he has seen the strongest animals succumb instantly when thus wounded, but the poison does not produce any effect on their meat. HOMOPHAGOUS AND POLYPHAGOUS. These are appellations given to certain individuals of a depraved appetite, that enables them to devour raw meat, and various other substances which most unquestionably would destroy any person not gifted or cursed with such an omnivorous digestion. Various are the ancient stories related of such voracious wretches. Ovid describes one Erisichthon, who, as a punishment for cutting down the groves of Ceres, (very possibly to obtain fuel to cook his food,) was sentenced to perpetual hunger, and terminated his gluttonous career by eating up his own limbs. Theagenes thought nothing of an ox for his dinner; and the famed Crotonian athlete, Milo, knocked down bullocks with his fist for his daily meals, which usually consisted of twenty _minae_ of meat and the same ration of bread. Vopiscus relates that a man was brought before the Emperor Maximilian, who devoured a whole calf, and was proceeding to eat up a sheep, had he not been prevented. To this day, in India, some voracious mountebanks devour a live sheep as an exhibition. Dr. Boehmen of Wittenberg witnessed the performance of one of these polyphagous individuals, who commenced his repast by eating a raw sheep, a sucking-pig, and, by way of dessert, swallowed sixty pounds of prunes, stones and all. On another festive occasion, he ate two bushels of cherries, with several earthen vases, and chips of a furnace. This meal was followed up by sundry pieces of glass and pebbles, a shepherd's bagpipe, rats, various birds with their feathers, and an incredible number of caterpillars. To conclude his dinner, he swallowed a pewter inkstand, with its pens, a pen-knife, and a sandbox. During this deglutition he seemed to relish his food, but was generally under the influence of potations of brandy. His form was athletic, and he could carry four heavy men on his shoulders for a league. He lived to the age of seventy-nine, but died in a most emaciated state, and, as might be imagined, toothless.
