MY private office was on the second floor of the sanitarium which I had fitted up in Kansas City to meet the demands of my large practice in the treatment of chronic diseases. The furniture consisted of a large book case, containing my library of standard works, and other publications useful in my practice; a writing desk, a few chairs, sofa and other conveniences usually found in such places. One door opened into the hall, and another connected with my bed chamber, bath room and laboratory in the rear. In the front was a large bay window where I often sat, in a meditative mood, concealed by the heavy lace curtains, looking out upon the throngs of people and numerous vehicles passing to and fro on the street below. On the opposite side of the main hall, and separated from it by the wide stairway, was the parlor where I received visitors. In the rear of this were the consultation and operating rooms. I usually lunched in my private office, my meals being sent up to me on an elevator, from a restaurant connecting directly with the sanitarium. As a rule, no one but the office boy, who occupied a small room over the stairway, was ever admitted to my private office. The boy attended the door, conducted visitors to the parlor, and then reported who was in waiting. If I cared to see them, I went around the head of the stairs to the parlor; otherwise I was "Not in." Many of my patients came from a distance and had lodgings and board in the sanitarium. Others called at my reception rooms during my regular office hours, which were from 9 to 11 A.M. At other hours I was ordinarily occupied in my private office, reading, thinking and writing, or in my laboratory compounding medicines, etc. But it was generally understood that I frequently drove out, and hence people calling to see me, except during office hours, were not surprised to learn that I could not be seen. This arrangement was an absolute necessity in order that I might have time to attend to my large correspondence and make my usual study of the diseases of patients who had placed themselves under my treatment as their last hope of regaining health. My success in treating these cases which had been given up as incurable, was such, that the sanitarium was always full, and it was a rare thing indeed, that I called upon patients at their homes. One bright and unusually pleasant day in June 189--, after I had attended to my patients, I retired to my private office, feeling that a call, even from my most intimate friends, would be very undesirable. I wanted to be alone. I had many letters to write, and other work that I could not well neglect, but I seemed in spite of myself to have lost my usual active interest in my business. I felt oppressed and dissatisfied with its restraints, and after worrying through with my most important correspondence, I got up and paced the floor to and fro.
