I reached an inner room where Doctor X was. He looked me over, while I described for him as best I could what seemed to be the matter with me, and asked me a number of intimate questions touching on the lives, works, characters and peculiarities of my ancestors; after which he made me stand up in front of him and take my coat off, and he punched me hither and yon with his forefinger. He also knocked repeatedly on my breastbone with his knuckles, and each time, on doing this, would apply his ear to my chest and listen intently for a spell, afterward shaking his head in a disappointed way. Apparently there was nobody at home. For quite a time he kept on knocking, but without getting any response. He then took my temperature and fifteen dollars, and said it was an interesting case--not unusual exactly, but interesting--and that it called for an operation. From the way my heart and other organs jumped inside of me at that statement I knew at once that, no matter what he may have thought, the premises were not unoccupied. Naturally I inquired how soon he meant to operate. Personally I trusted there was no hurry about it. I was perfectly willing to wait for several years, if necessary. He smiled at my ignorance. "I never operate," he said; "operating is entirely out of my line. I am a diagnostician." He was, too--I give him full credit for that. He was a good, keen, close diagnostician. How did he know I had only fifteen dollars on me? You did not have to tell this man what you had, or how much. He knew without being told. I asked whether he was acquainted with Doctor Y--Y being a person whom I had met casually at a club to which I belong. Oh, yes, he said, he knew Doctor Y. Y was a clever man, X said--very, very clever; but Y specialized in the eyes, the ears, the nose and the throat. I gathered from what Doctor X said that any time Doctor Y ventured below the thorax he was out of bounds and liable to be penalized; and that if by any chance he strayed down as far as the lungs he would call for help and back out as rapidly as possible. This was news to me. It would appear that these up-to-date practitioners just go ahead and divide you up and partition you out among themselves without saying anything to you about it. Your torso belongs to one man and your legs are the exclusive property of his brother practitioner down on the next block, and so on. You may belong to as many as half a dozen specialists, most of whom, very possibly, are total strangers to you, and yet never know a thing about it yourself.
