These reserves made, it is clear that removal of the patient from his environment has its advantages, but it is better to maintain only a degree of isolation, and to allow him to come into his own circle from time to time, under a wise supervision. The ideal measure would be to consign him to the care of an attentive and devoted teacher, whose superintendence would be permanent. In this respect, unfortunately, all that we can do at present is to indicate what we think a desideratum, for while well-to-do families may have their tutor, we do not know of any one who has held a corresponding office as an instructor of children with tic. The realisation of this novel proceeding might present genuine difficulties in practice, but we may hope that once parents, patients, and physicians are acquainted with the nature of tics and the efficacy of the re-education method, many prejudices against that fruitful therapeutic contrivance will vanish. PSYCHOTHERAPY Immobilisation and regulation of exercise and occupation do not constitute the whole of the treatment; they form merely its objective side. Psychotherapy is another factor, of capital importance. In the words of Brissaud, psychotherapy is an _ensemble_ of agencies calculated to demonstrate to the patient where his will is at fault, and how to exercise to the best advantage what of it is left. To come to particulars, his defect lies in his inability to check a cortical caprice. These are not rhetorical unrealities, nor is there anything mysterious about the method; it demands no special competence beyond the gentle and encouraging firmness of the ideal teacher. The physician can constitute himself instructor without having to borrow from the more or less occult practices of hypnotic suggestion. In fact, we must make it clear to the patient that the co-operation of the latter is indispensable, and that it is his will which is to come into action. The personal influence of the teacher will be exerted in sustaining his pupil's efforts, in making him take note of the progress effected, in keeping him to the allotted times for exercise and drill. Thus, and thus only, is psychotherapy to be applied to tic. Lucid and sincere explanations and kindly counsels are wanted, not ceremonies and mysterious paraphernalia. Resoluteness, patience, clemency, and good sense are the weapons in the physician's armamentarium; docility, faith, and perseverance, on the patient's part, will enable him to emerge victorious. As soon as the compact is made, the battle against bad habits, where there is neither truce nor quarter, commences in earnest. The victim to tic will speedily unlearn the habit of perpetuating bad habits; he will, in addition, learn the habit of not contracting bad habits. In this way a double benefit--physical as well as moral--will accrue.
