Now, the epidermis of a snake covers the entire head, _including the eyes!_ And what would that snake do when the time came to remove the scales from its eyes and lips? It continued to lie perfectly still! When the pulling off of the old skin hurt the new skin underneath, the head flinched slightly, just as any hurt flesh will flinch by reflex action; but that was absolutely all. For a long hour or more, and even when the men pulled the dead scales from those eyes and lips, that strange creature made no resistance or protest. I have seen many people fight their doctors for less. That wild, newly-caught jungle snake quickly had recognized the situation, and acted its part with a degree of sense and appreciation that was astounding. I do not know of any _adult wild_ mammal that would have shown that kind and degree of wisdom under similar circumstances. Do Snakes "Charm" Birds? Sometimes a wild bird will sit still upon its nest while a big pilot blacksnake, or some other serpent equally bad, climbs up and poises its head before the motionless and terrified bird until at last the serpent seizes the bird to devour it. The bird victim really seems to be "charmed" by its enemy. If there were not some kind of a hypnotic spell cast over the bird, would it not fly away? I think this strange proceeding is easily explainable by any one with sufficient imagination to put himself in the bird's place. It is the rule of a sitting bird to sit tight, not to be scared off by trifles, and to take great risks rather than expose her eggs to cold and destruction. The ascent and approach of the serpent is absolutely noiseless. Not a leaf is stirred. The potential mother of a brood calmly sits with eyes half closed, at peace with all the world. Suddenly, and with a horrible shock, she discovers a deadly serpent's multi-fanged head and glittering eyes staring at her _within easy striking distance._ The horrified mother bird feels that she is lost. She knows full well that with any movement to escape the serpent instantly will launch its attack. _Her one hope,_ and seemingly her only chance for life, is that _if she remains motionless_ the serpent will go its way without harming her. (Think of the thousands of helpless men, women and children who have hoped and acted similarly in the presence of bandits and hold-up men presenting loaded revolvers! But they were far from being "charmed.") The bird hopes, and sits still, _paralyzed with fear._ At its leisure the serpent strikes; and after a certain number of horrible minutes, all is over. I think there is no real "charm" exercised in the tragedy; but that there is on the part of the bird a paralysis of fear, which is in my opinion a well defined emotion, common in animals and in men. I have seen it in many animals.
