Patients who in their own homes enjoy sanitary and hygienic care; who may have a room of ample size for their exclusive use, which is thoroughly aired, day and night; who are provided with the "right kind of nourishment," and who will obey implicitly the rules which the physician, who is conversant with this particular method of treatment, will lay down, may be assured that a prompt response will ensue. The intelligent reader will understand that this statement does not apply to patients in the last stages of the disease. The assertion, however, must rightly be regarded as revolutionary. It is not what we were taught--it emphasizes, nevertheless, what every physician already knows, that, theoretically, consumption is a disease that should respond to treatment. That we have not had greater success with it in the past, must be attributed to our method of treatment. The fact that most of us have had the disease, and have recovered, conclusively demonstrates its curability. Those individuals who fail to recover promptly do not possess the vitality to throw it off spontaneously. If at this time--the real beginning of the disease--it is discovered, and the right treatment instituted, we immediately supply the organism with the ingredients it is deficient in and we are justified in looking for favorable results if the patient adheres to the instructions. The second essential in the treatment of consumption is an abundance of fresh, pure air. We therefore direct the patient to remain in the open as much as is possible. If circumstances permit him to sleep out-of-doors, so much the better; if not, he must sleep in a room with the windows open to the fullest extent, winter and summer. There are no exceptions to this rule. If it storms, the outside blinds may be closed, but the windows must remain open. The city air is just as efficient for our purpose as is the air of any other vicinity--the point is, to get enough of it from a mechanical standpoint. The advantages from sending patients away, even under the old belief, were more than discounted by conditions incident to the new environment that were detrimental to their progress. Now that we know it is not necessary or essential to procure any other kind or quality of air than exists in any city, all our efforts may be concentrated in the interest of the patient in directing the "right kind of nourishment" and in supervising his conduct. In few instances is it necessary to prescribe any medicine. In exceptional cases the cough may require some sedative remedy, especially if it disturbs the patient at night. Experience has taught us, however, that to live twelve hours in the open air and to sleep with the windows wide open, will do more for the cough than any medicine we possess.
