On that score I felt that I had played my cards well, but there were other thoughts that troubled me, chief of which was a fear that some investigation might be set on foot in regard to Marguerite and that her guardianship of the library of forbidden books might be discovered. With this worry to torment me, the hours dragged slowly enough. I had been some five days in this solitary confinement when the door opened and a man entered. He wore the uniform of a physician and introduced himself as Dr. Boehm, explaining that he had been sent by His Majesty to look after my health. The idea rather amused me; at least, I thought, the Emperor had decided that the secrets of my brain were well worth preservation, and I reasoned that this was evidence that the Chemical Staff had made an effort to duplicate my work and had reported their failure to do so. The doctor made what seemed to me a rather perfunctory physical examination, which included a very minute inspection of my eyes. Then he put me through a series of psychological test queries. When he had finished he sighed deeply and said: "I am sorry to find that you are suffering from a disturbed balance of the altruistic and the egotistic cortical impulses; it is doubtless due to the intensive demands made upon the creative potential before you were completely recovered from the sub-normal psychosis due to the gas attack in the potash mines." This diagnosis impressed me as a palpable fraud, but I became genuinely alarmed at the mention of the affair at the potash mines. I was somewhat reassured at the thought that this reference was probably a part of the record of Karl Armstadt, which was doubtless on file at the medical headquarters, and had been looked up by Dr. Boehm who was in need of making out a plausible case for some purpose--perhaps that of confining me permanently on the grounds of insanity. Whatever might be the move on foot it was clearly essential for me to keep myself cool and well in hand. The doctor, after eyeing me calmly for a few moments, said: "It will be necessary for me to go out for a time and secure apparatus for a more searching examination. Meanwhile be assured you will not be further neglected. In fact, I shall arrange for the time to share your apartment with you, as loneliness will aggravate your derangement." In a few hours the doctor returned. He brought with him a complicated-looking apparatus and was followed by two attendants carrying a bed. The doctor pushed the apparatus into the corner, and, after seeing his bed installed in my sleeping chamber, dismissed the attendants and sat down and began to entertain me with accounts of various cases of mental derangement that had come under his care. So far as I could determine his object, if he had any other than killing time, it was to impress me with the importance of submitting graciously to his care.
