The time for a discussion of occupation as a means of cure or betterment in cases of mental disorder has long been overdue, and needs no apology. The papers which have been read deal with its practical aspect, and relate in a convincing way what has actually been accomplished. My aim is twofold. In the first place, I wish to give a short historical résumé of occupation as it has affected Gartnavel, and in the second place, to discuss its importance and value.
