Predisposition to Nervousness.

—Heredity plays an important rôle in the predisposition to nervousness, so that children of nervous parents are particularly likely to show nervous instability. It is, however, difficult to say in a given case how much of his nervousness a child inherits and how much he acquires by imitating the irritability, the out-breaks of temper, and the other evidences of imperfect emotional control displayed by his nervously disposed parents. On the other hand, even children of nervous predisposition sometimes overcome their defects to some extent by imitating parents who have acquired self-control.

Children predisposed to nervousness should be watched with special care, but they should not be allowed to realize that they are the objects of unusual solicitude. They need the most favorable surroundings that can be obtained, and their general health should be maintained at the highest possible level. Any condition that lowers vitality tends to increase their troubles; nervousness may be caused among children of good inheritance, and increased among others, by poor nutrition, lack of exercise and play out-of-

doors, fatigue, loss of sleep, eyestrain, adenoid growths, and the poisons of infectious diseases.

It is characteristic of many nervous children that they are too easily stimulated; they may be excitable, restless, unnaturally quick in moving, over-sensitive to pain and discomfort, easily fatigued, irritable in temper, and unable to control the emotions. They frequently make involuntary motions like grimacing and winking the eyes. Children of low nervous tone, however, are not necessarily excitable. A nervous child may be muscularly weak, awkward in gait, listless, dull, clumsy, forgetful, and inattentive. Such children often suffer from cold hands and feet and from profuse perspiration.

Much can be done for these unfortunate children by removing the cause of their troubles if possible, by giving them simple and wholesome surroundings, by suiting their occupations to their strength, by eliminating mental strain, particularly during the adolescent period, and by training them to control their minds as well as their bodies.

"In addition to the hardening of the body, the education of the child should include measures which increase the resistance of the child against pain and discomforts of various sorts. Every child, therefore, should undergo a gradual process of 'psychic hardening' and be taught to bear with equanimity the pain and discomfort to which everyone sooner or later cannot help but be exposed. What I have said about clothing, cold baths, walking in all weather and at all temperatures, play and exercise in the open air, has a bearing on this point, for a child who has formed good habits in these various directions will have learned many lessons in the steeling of his mind to bear pain and to ignore small discomforts."—(Barker: "Principles of Mental Hygiene Applied to the Management of Children Predisposed to Nervousness.")

CONVALESCENT PATIENTS

After serious or prolonged illness the vitality is generally low and all bodily processes are likely to be depressed. During convalescence, therefore, the digestion is feeble, the muscles are weak so that fatigue follows slight exertion, and the sluggish condition of the circulation renders the patient especially sensitive to cold. Since the nervous system also becomes depressed and irritable, a convalescent patient is easily excited, easily discouraged, and quickly fatigued by mental effort. He finds the simplest decisions hard to make, and his emotions difficult to control; indeed, many a patient who has borne acute pain with unflinching courage becomes peevish at this stage, weeps easily, and expects more expression of sympathy than is good for him. Some persons naturally make quick recoveries, while
