Where masturbation is simply an evidence of loss of self-control, it is met best by constant watching, and gradually, as the mental state improves, arranging the daily life so as to develop the feeling of self-respect. Where it depends upon local paræsthesia, opium and camphor and cold bathing are indicated. Constipation is a troublesome symptom, especially in the states of mental depression. When a full, laxative diet, cod-liver oil, and malt do not correct it, small doses of laxatives given frequently act better than the occasional use of purgatives. There is a class of cases which are best treated by educating the patients as one would educate a child. In the general care of the insane it is the duty of the state to see that they have all the rights of the citizen which are consistent with their proper and safe treatment, including the benefits of property and estate. There certainly should be in all countries, as in England, officers whose duty it is to see that this is done. For a large number of people with defective or diseased brains, who are now allowed to wander about committing crimes and serving repeated sentences in reformatories, houses of correction, and prisons, an enlightened public policy would find the best, and in the end the cheapest, treatment to consist in keeping them under supervision and control as unsound members of society. The more particular treatment of the insane differs in the various mental diseases, varying as it necessarily must according to different conditions. Its prevention is not an easy problem. Many of the external causes of insanity seem inevitable in our complex civilization: it would be impossible to widely regulate marriages, even if we knew how; those people predisposed to insanity are usually too self-confident and self-willed to receive advice; and moderation in all things, healthful occupation, temperate habits, good digestion, and, above all, out-of-door life, seem as much like a sarcasm if suggested to many of the toilers as a waste of words if recommended to the idle and luxurious, while the parents who have transmitted to their children unstable or diseased brains generally impair what chances they have in life by vicious training.
