Hallucination.—“Hallucinations,” says a medical authority, “are very common among those who are partially insane. They occur as a result of fever and frequently accompany delirium. They result from an impoverished condition of the blood, especially if it is due to starvation, indigestion, and the use of drugs like belladonna, hyoscyarnus, stramonium, opium, chloral, cannabis indica, and many more that might be mentioned.” Large numbers of cases of attempted cure by hypnotism, successful and unsuccessful, might be quoted. There is no doubt that in the lighter forms of partial insanity, hypnotism may help many patients, though not all; but when the disease of the brain has gone farther, especially when a well developed lesion exists in the brain, mental treatment is of little avail, even if it can be practiced at all. A few general remarks by Dr. Bernheim will be interesting. Says he: “The mode of suggestion should be varied and adapted to the special suggestibility of the subject. A simple word does not always suffice in impressing the idea upon the mind. It is sometimes necessary to reason, to prove, to convince; in some cases to affirm decidedly, in others to insinuate gently; for in the condition of sleep, just as in the waking condition, the moral individuality of each subject persists according to his character, his inclinations, his impressionability, etc. Hypnosis does not run all subjects into a uniform mold, and make pure and simple automatons out of them, moved solely by the will of the hypnotist; it increases cerebral docility; it makes the automatic activity preponderate over the will. But the latter persists to a certain degree; the subject thinks, reasons, discusses, accepts more readily than in the waking condition, but does not always accept, especially in the light degrees of sleep. In these cases we must know the patient’s character, his particular psychical condition, in order to make an impression upon him.” Bad Habits.—The habit of the excessive use of alcoholic drinks, morphine, tobacco, or the like, may often be decidedly helped by hypnotism, if the patient wants to be helped. The method of operation is simple. The operator hypnotizes the subject, and when he is in deep sleep suggests that on awaking he will feel a deep disgust for the article he is in the habit of taking, and if he takes it will be affected by nausea, or other unpleasant symptoms. In most cases the suggested result takes place, provided the subject can be hypnotized al all; but unless the patient is himself anxious to break the habit fixed upon him, the unpleasant effects soon wear off and he is as bad as ever.
