and persistent. Nor does it tell us if later in life, but before the suffering from the pea arose, she had been taken to consult two famous doctors, one of whom had removed the vermiform appendix, while the other a little later had performed an operation for "adhesions." At any rate, the story with these later additions, which are at least in keeping with what we know of her history, would serve to indicate the importance which attaches to the early training of childhood. Among the children even of the well-to-do often enough the hygiene of the mind is overlooked, and faulty management produces restlessness, instability, and hyper-sensitiveness, which pass insensibly into neuropathy in adult life.

To prevent so distressing a result is our aim in the training of children. No doubt the matter concerns in the first place parents and nurses, school masters and mistresses, as well as medical men. Yet because of the certainty that physical disturbances of one sort or another will follow upon nervous unrest, it will seldom happen that medical advice will not be sought sooner or later; and if the physician is to intervene with success, he must be prepared with knowledge of many sorts. He must be prepared to make a thorough and complete physical examination, sufficient to exclude the presence of organic disease. If no organic disease is found, he must explore the whole environment of the child, and seek to determine whether the exciting cause is to be found in the reaction of the child to some form of faulty management.

For example, a child of two or three years of age may be brought to the doctor with the complaint that defæcation is painful, and that there has existed for some time a most distressing constipation which has resisted a large number of purgatives of increasing strength. Whenever the child is placed upon the stool, his crying at once begins, and no attempts to soothe or console him have been successful. It is not sufficient for the doctor in such a case to make an examination which convinces him that there is no fissure at the anus and no fistula or thrombosed pile, and to confine himself to saying that he can find nothing the matter. The crying and refusal to go to stool will continue after the visit as before, and the mother will be apt to conclude that her doctor, though she has the greatest confidence in him for the ailments of grown-up persons, is unskilled in, or at least not interested in, the diseases of little children. If, on the other hand, the doctor pursues his inquiries into the management of the child in the home, and if, for example, he finds that the crying and resistance is not confined to going to stool, but also takes place when the child is put to bed, and very often at meal-times as well, then it will be safe for him to conclude that all the symptoms are due to the same cause—a sort of "negativism" which is apt to appear in all children who are directed and urged too much, and whose parents are not careful to hide from them the anxiety and distress which their conduct occasions.

If this diagnosis is made, then a full and clear explanation should be given to the mother, or at any rate to such mothers—and fortunately they are in the majority—who are capable of appreciating the point of psychology involved, and of correcting the management of the child so as to overcome the negativism. To attempt treatment by prescribing drugs, or in any other way than by correcting the faulty management, is to court failure. As Charcot has said, in functional disorders it is not so much the prescription which matters as the prescriber.

But the task of the doctor is often one of even greater difficulty. Often enough there will be a combination of organic disturbance with functional trouble. For example, a girl of eighteen years old suffered from a pain in the left arm which has persisted on and off since the olecranon had been fractured when she was two years of age. She was the youngest of a large family, and had never been separated for a day from the care and apprehensions of her mother. The joint was stiff, and there was considerable deformity. The pain always increased when she was tired or unhappy. Again, a girl had some slight cystitis with frequent micturition, and this passed by slow degrees into a purely functional irritability of the bladder, which called for micturition at frequent intervals both by day and night. In such cases treatment must endeavour to control both factors—the local organic disturbance must if possible be removed, and the faults of management corrected.

It is a good physician who can appreciate and estimate accurately the temperament of his patient, and the need for this insight is nowhere greater than in dealing with the disorders of childhood. It can be acquired only by long practice and familiarity with children. In the hospital wards we shall learn much that is essential, but we shall not learn this. The child, who is so sensitive to his environment, shows but little that is characteristic when admitted to an institution. Only in the nursery can we learn to estimate the influences which proceed from parents and nurses of different characters and temperaments, and the reaction which is produced by them in the child.

The body of the child is moulded and shaped by the environment in which it grows. Pure air, a rational diet, free movement, give strength and symmetry to every part. Faults of hygiene debase the type, although the type is determined by heredity which in the individual is beyond our control. Mothers and nurses to-day are well aware of the need for a rational hygiene. Mother-craft is studied zealously and with success, and there is no lack of books to give sound guidance and to show the mean between the dangerous extremes of coddling and a too Spartan exposure. Yet sometimes it has seemed as if some mothers whose care for their children's physical health is most painstaking, who have nothing to learn on the question of diet, of exercise, of fresh air, or of baths, who measure and weigh and record with great minuteness, have had their attention so wholly occupied with the care of the body that they do not appreciate the simultaneous growth of the mind, or inquire after its welfare. Yet it is the astounding rapidity with which the mental processes develop that forms the distinguishing characteristic of the infancy of man. Were it not for this rapid growth of the cerebral functions, the rearing of children would be a matter almost as simple and uneventful as the rearing of live stock. For most animals faults of environment must be very pronounced to do harm by producing mental unrest and irritability. Thus, indeed, some wild animal separated from its fellows and kept in solitary captivity may sicken and waste, though maintained and fed with every care. Yet if the whole conditions of life for the animal are not profoundly altered, if the environment is natural or approximately natural, it is as a rule necessary to care only for its physical needs, and we need not fear that the results will be spoiled by the reaction of the mind upon the body. But with the child it is different; airy nurseries, big gardens, visits to the seaside, and every advantage that money can buy cannot achieve success if the child's mind is not at rest, if his sleep is broken, if food is habitually refused or vomited, or if to leave him alone in the nursery for a moment is to evoke a fit of passionate crying.

The grown-up person comes eventually to be able to control this tremendous organ, this brain, which is the predominant feature of his race. In the child its functions are always unstable and liable to be upset. Evidence of mental unrest or fatigue, which is only rarely met with in grown persons and which then betokens serious disturbance of the mind, is of
