Dr. Cocke treated a large number of cases, which he reports in detail in his book on hypnotism. In a fair proportion of the cases he was successful; in some cases completely so. In other cases he failed entirely, owing to lack of moral stamina in the patient himself. His conclusions seem to be that hypnotism may be made a very effective aid to moral suasion, but after all, character is the chief force which throws off such habits once they are fixed. The morphine habit is usually the result of a doctor’s prescription at some time, and it is practiced more or less involuntarily. Such cases are often materially helped by the proper suggestions. The same is true of bad habits in children. The weak may be strengthened by the stronger nature, and hypnotism may come in as an effective aid to moral influence. Here again character is the deciding factor. Dr. James R. Cocke devotes a considerable part of his book on “Hypnotism” to the use of hypnotism in medical practice, and for further interesting details the reader is referred to that able work. CHAPTER X. Hypnotism of Animals.—Snake Charming. We are all familiar with the snake charmer, and the charming of birds by snakes. How much hypnotism there is in these performances it would be hard to say. It is probable that a bird is fascinated to some extent by the steady gaze of a serpent’s eyes, but fear will certainly paralyze a bird as effectively as hypnotism. Father Kircher was the first to try a familiar experiment with hens and cocks. If you hold a hen’s head with the beak upon a piece of board, and then draw a chalk line from the beak to the edge of the board, the hen when released will continue to hold her head in the same position for some time, finally walking slowly away, as if roused from a stupor. Farmers’ wives often try a sort of hypnotic experiment on hens they wish to transfer from one nest to another when sitting. They put the hen’s head under her wing and gently rock her to and fro till she apparently goes to sleep, when she may be carried to another nest and will remain there afterward. Horses are frequently managed by a steady gaze into their eyes. Dr. Moll states that a method of hypnotizing horses named after its inventor as Balassiren has been introduced into Austria by law for the shoeing of horses in the army. We have all heard of the snake charmers of India, who make the snakes imitate all their movements. Some suppose this is by hypnotization. It may be the result of training, however. Certainly real charmers of wild beasts usually end by being bitten or injured in some other way, which would seem to show that the hypnotization does not always work, or else it does not exist at all. We have some fairly well known instances of hypnotism produced in animals. Lafontaine, the magnetizer, some thirty years ago held public exhibitions in Paris in which he reduced cats, dogs, squirrels and lions to such complete insensibility that they felt neither pricks nor blows.
