"I can't say; for the naturalists, who have been as much puzzled as you are by this peculiarity, have been unable to explain it." "Then I am more learned than they are," said l'Encuerado, with a magisterial air. "Do you know, then, why toucans have such exaggerated beaks?" "Because they have been made by a wise Creator," replied the Indian. "No doubt about that," remarked Sumichrast, smiling; "but the point is, why they were made so." "Because their beak, calcined and reduced to powder, is the only efficacious remedy for epilepsy. Toucans are very scarce birds, and if their beaks were no larger than those of other birds of their size, this medicine could never be obtained in sufficient quantities." L'Encuerado's explanation was perhaps as good as our uncertainty. I remember that the Indians do, in fact, make a great mystery of a powder against epilepsy, and that a toucan's head may often be noticed hanging up to the wall of a hut, as a preservative against St. Vitus' dance. Instead of resting, Lucien prowled about in every direction, breaking away bark, and lifting stones with all the ardor of a neophyte in entomology. Since meeting with the coral-serpent, he took precautions which gave me confidence; for it is quite uncertain how a reptile or any other creature may behave when it is disturbed. The child suddenly called out to me; he had just discovered a nest of _scolopendrae_, commonly called centipedes, and he was afraid to touch them. The centipedes, surprised at being disturbed, rolled themselves up; their pale blue color somewhat diminishing the repugnance which their appearance generally excites. It was not without some hesitation that Lucien, encouraged by Sumichrast, ventured to place one on the palm of his hand; the insect gradually unrolled its articulations, each of which was provided with two pairs of feet ending in hooks, but its walk was so slow as rather to disappoint the young observer. "What is the use of having forty-four feet," he cried, "if the centipede can not get on faster than a _carabus_, which only has six?" L'Encuerado could alone explain this mystery; but still he kept silence. "Are these creatures poisonous, M. Sumichrast?" "It is said so; but some species--that, for instance, which you are examining--may be handled without danger." "Here is a little centipede with only twelve legs." "It has only just come out of the egg; their rings increase in number as they grow older, and this is one of their peculiarities." "How hard the rings, are! they are almost like armor." "It is armor, in fact; the _scolopendrae_ form a line of demarkation, so to speak, separating insects from crustaceans; centipedes are not very distant relations of lobsters." "Look, papa! I have just found a chocolate-colored worm, which looks like a centipede." "That's not a worm; it is an _iulus_, first cousin to the centipede. Don't take it up in your hand, for it will impregnate your fingers with a sickening odor."
