Probably the very best illustration in the whole range of medicine of the place of the will in the cure of disease is afforded by tuberculosis. This used to be the most fatal of all human affections until displaced from its "bad eminence" within the last few years by pneumonia, which now carries off more victims. As it is, however, about one in nine or perhaps a few more of all those who die are victims of tuberculosis. This high mortality would seem to indicate that the disease must be very little amenable to the influence of the will, since surely under ordinary circumstances a good many people might be expected to have the desire and the will to resist the affection if that were possible. In spite of the large death rate this is exactly what is true.
Tuberculous infections are extremely common, much commoner even than their high mortality reveals. After long and critical discussion with a number of persistent denials, it is now generally conceded by authorities in the disease that the old maxim "after all, all of us are a little tuberculous" is substantially correct. Very few human beings entirely escape infection from the tubercle bacillus at some time in life. The great majority of us never become aware of the presence of the disease and succeed in conquering it, though the traces of it may be found subsequently in our bodies. Careful autopsies reveal, however, that very few even of those who did not die directly from tuberculosis fail to show tuberculous lesions, usually healed and well shut off from the healthy tissues, in their bodies. One in eight of those who become infected have not the resistive vitality to throw off the disease or the courage to face it and take such precautions as will prevent its advance. All those, however, who give themselves any reasonable chance for the development of resistance survive the disease though they remain always liable to attack from it subsequently if they should run down in health and strength.
Heredity, which used to be supposed to play so important a rôle in the affection, is now known to have almost nothing to do with the spread of the disease. Family tendencies are probably represented by nothing more than a proneness to underweight which makes one more liable to infection, and this is due as a rule to family habits in the matter of undernourishment from ill-advised consumption of food. Probably a certain lack of courage to face the disease boldly and do what is necessary to develop bodily resistance against it may also be an hereditary family trait, but environment means ever so much more than heredity.
There is a well known expression current among those who have had most experience in the treatment of patients suffering from tuberculosis that "tuberculosis takes only the quitters", that is to say that only those succumb to consumption who have not the strength of will to face the issue bravely and without discouragement to push through with the measures necessary for the treatment of their disease. In a word it is only those who lack the firmness of purpose to persist in the mode of life outlined for them who eventually die from their affection of the [{170}] lungs. No specific remedy has been found that gives any promise of being helpful, much less of affording assured recovery, though a great many have been tried and not a few are still in hopeful use. Recent experience has only served to emphasize the fact that the one thing absolutely indispensable for any successful treatment of tuberculosis of the lungs is that the patient should regain weight and strength and with them resistive vitality so as to be able to overcome the disease and get better.
To secure this favorable result two conditions of living are necessary but they must be above all persisted in for a considerable period. First there must be an abundance of fresh air with rest during the advancing stage or whenever there are acute symptoms present, and secondly an abundance of good food which will provide a store of nutritive energy and make the resistive vitality as high as possible. Curiously enough this "fresh air and good food" treatment for the disease was recognized as the sheet anchor of the therapeutics of consumption as long ago as Galen's time, the end of the second century, when that distinguished Greek physician was practising at Rome. Nearly eighteen hundred [{171}] years ago Galen suggested that he had tried many remedies for what he called phthisis, the Greek equivalent of our word consumption or wasting away, and had often thought that he had noted a remedial value in them, but after further experience he felt that the all-important factors for cure were fresh air and good food. He even went so far as to say that he thought the best food of the consumptive or the phthisical, as he called them, was milk and eggs. A great deal of water has flowed under the bridge of medical advance since his time and at many periods since physicians have been sure that they had valuable remedies for consumption; yet here we are practically back at Galen's conclusion more than fifty generations after his time, and we are even inclined to think of this mode of treatment as comparatively new, as it is in modern history.
The influence on consumption of the will to get well when once aroused was typically exemplified in the career of the well-known London quack of the beginning of the nineteenth century, St. John Long. He set himself up as having a sure cure for consumption. He was a charlatan of the deepest dye whose one idea was to make money, and who knew [{172}] nothing at all about medicine in any way. He took a large house in Harley Street and fitted it up for the reception of people anxious to consult him. For some seasons every morning and afternoon the public way was blocked up with carriages pressing to his door. Nine out of ten of his patients were ladies and many of them were of the highest rank; fashion and wealth hastened to place themselves and their daughters at the mercy of the pretender's ignorance. His mode of treatment was by inhalation. He assured his patients that the breathing in of this medicated vapor would surely cure their pulmonary disease, and because others were intent on going they went; many of them were greatly benefited for a time and these so-called cures proved a bait for many other patients.
J. Cordy Jeaffreson in his volume "A Book about Doctors", written two generations ago, has told the story of St. John Long's successful application of the principle of community of treatment and its effectiveness upon his patient. Like Mesmer he realized that treating people in groups led them mutually to influence each other and to bring about improvement. St. John Long [{173}] had in one of the rooms in Harley Street "two enormous inhalers, with flexible tubes running outward in all directions and surrounded by dozens of excited women— ladies of advanced years and young girls giddy with the excitement of their first London season—puffing from their lips the medicated vapor or waiting until a mouthpiece should be at liberty for their pink lips." In our generation of course we had various phases of similar treatment, including nebulizers and compressed air apparatus and medicated vapor, all working wonders for a while, and then proving to have no physical beneficial effect.
What is surprising is to find the number of cures that were worked. St. John Long had so many applicants for attention that he was literally unable to give heed to all of them. The news of the wonderful remedy flew to every part of the United Kingdom and from every quarter sick persons, wearied of a vain search after an alleviation of their sufferings, flocked to London with hope renewed once more. This enabled St. John Long to select for treatment only such cases as gave ready promise of cure. He made it a great preliminary of his treatment that his [{174}] patients should eat well as a rule and on one occasion when he was called into the country to see a man suffering in the last stages of consumption he said quite frankly, "Sir, you are so ill that I cannot take you under my charge at present. You want stamina. Take hearty meals of beefsteak and strong beer; and if you are better in ten days I will do my best for you and cure you."
