At that time I had the impression that the treatment was largely due to the force of Mr. Towns's very vigorous and helpful personality, but when subsequently a similar institution was established near Boston, I became convinced by observation of cases treated in that hospital that Mr. Towns's personality was not an essential element in that treatment. His skill, however, in the actual management of cases, from the medical point of view, was very hard to duplicate, and Mr. Towns generously came from New York, when called upon, and showed us what was wrong in the management of cases which were not doing well. I do not hesitate to say that he knows more about the alleviation and cure of drug addictions than any doctor that I have ever seen. All the statements made in this book except those relating to tobacco I can verify from similar experiences of my own, since I have known and used Mr. Towns's method of treatment. I do not pretend to say how his treatment accomplishes the results which I have seen it accomplish, but I have yet to learn of any one who has given it a thorough trial who has obtained results differing in any considerable way from those to which Mr. Towns refers. The wider applications and generalizations of the book seem to me very instructive. The shortcomings of the medical profession, of the druggists, and those who have to do with the management of alcoholics in courts of law seem to me well substantiated by the facts. Mr. Towns's plans for legislative control of drug habits also seem to me wise and far-reaching. He is, I believe, one of the most public-spirited as well as one of the most honest and forceful men that I have ever known. I am glad to have this opportunity of expressing my faith and confidence in him and my sense of the value of the book he has written. RICHARD C. CABOT. INTRODUCTION
