The three remedies, which are nature's own methods, are good food, fresh air, and rest. It is difficult to say which of these three items is the most important. Certainly no hope of building up the resistance of the patient against the inroads of the disease can be expected unless the patient is thoroughly nourished. One of the sad facts in connection with those unfortunates whose fight against tuberculosis is nearly over and who in desperation have fled to Arizona, hoping that the dry air might afford relief, is that the lack of nourishing food, inevitable in those deserts, hastens on the disease, so that the expected benefits from the dry air are entirely offset. Likewise, in tenement-house districts in cities, the fight against consumption is practically useless because of the impossibility of securing for those starved or underfed helpless ones the nourishing food necessary. In the country, this part of the treatment ought to be the simplest, and yet one fears that the habit of eating through nine months of the year only salted and dried foods has not furnished patients in the country with the kind of nourishment necessary. Experience indicates that eggs and milk should be the bulwark on which the patient must depend for food, and in the sanitariums of New York State it is not uncommon for patients to be stuffed with two dozen raw eggs every day in addition to other food. The next important factor is rest, since the effect of tuberculosis is to break down lung tissue, and for the prevention of this it is necessary to give the forces of the body every aid in preventing this destruction. All exercise taken by a tuberculous patient means the withdrawing of that much blood from the lungs, where is the strategic point of the disease, to the part of the body being exercised, and one of the most striking features of sanitarium treatment is the absolute rest enjoined on the patients. Flat on their backs, day and night for months, without so much exercise as walking across the room, is the ordinary treatment, and the effect of disobedience is plainly seen in the rise in temperature or increase in fever which follows a violation of these rules. Even when the patients are allowed to sit up, they do not sit straight, but rest on couches or reclining chairs, so that their heads are down and their feet up, making the passage of the blood to the lungs easier. Even where the patient, determined to recover, is not able to place himself in the hands of a hospital physician, he can adopt this important method of arresting the disease by strictly avoiding exercise and exertion of every sort. The Massachusetts General Hospital in Boston has tuberculosis clinics, where patients who are not far enough advanced in the disease to require absolute rest are inspected daily, their condition noted, and advice given for the following twenty-four hours. One of the most common violations of the prescriptions given is
