The great difficulty which the doctor meets with in the management of these cases arises from the incredulity with which his opinion is received. Candour is looked upon as so eminently characteristic of childhood, that deceit seems impossible; the case is thought by the parents to be an obscure one which the doctor does not understand; and therefore it is said, he, with want of straightforwardness and of kindness, throws doubts on the existence of disease, and on the truthfulness of a most loving, most suffering child. The vagaries of a hysterical girl, the fits, the palsy, the half-unconsciousness have all been assumed within my own observation by children from ten to fifteen years old, and I have more than once had to give place to the ignorant and impudent pretender who traded successfully on the feelings of the parents. Sometimes, one knows not why, except that the child has got tired of the part he was playing, the symptoms that had caused so much anxiety suddenly disappear, but even then the habit of mind left behind is anything but healthy. Indeed in all cases of this kind it is much less the state of the body than that of the mind which excites my apprehension. The constant watching its own sensations, the habit of constantly gratifying every wayward wish and temper under the plea of illness, and the constant indulgence which it too often meets with in this from the over-kindness of its parents, exert a most injurious influence on its character, and it grows up a juvenile hypochondriac. A doctor is very unlikely to throw doubt recklessly on the reality of a child's illness. His hesitation should certainly not be attributed to unworthy motives; the parents should co-operate with him heartily in any course of observation which he desires to follow, and if necessary another medical man of experience should be associated with the first, and allowed to visit the child two or three times. One does not associate the idea of moral delinquency with hysteria; the child who shams belongs to the same class with the hysterical patient. It is only the strangeness of the occurrence in the eyes of non-medical people, that makes them fancy it something worse.
