Next, he bound his head and body with wide strips of cloth, surrounding the loins, and up to the lower parts of the breasts, with some fifteen wrappings. This being satisfactorily accomplished, he threw a greatcoat over his shoulders, and said: "I will now explain the working of the various apparatus which we have placed in position. After I have wrapped my face, as I will show you later on, I will lie down within this mold; you will then place the door, supporting me upon it, on its hinges and close the catch. Through the small glass door in the upper part of the case, you will arrange this platinum tube from my mouth to the orifice in the side of the case, just here where this wheel is," and he pointed to a little wheel made on the end of a projecting tube through the side of the case. "Opening the small door, you will have free access to my body, and you will attach the bandages upon my face to the little spring catch which you see upon the inside of the case, near the upper part. Cover my face and bandages well with plaster of Paris, so that no entrance may be given to the ozone. Take those eight bottles of ozone, and quickly empty the contents upon both sides of my body, into the side troughs which you see, and at once close the door. I will take this position at 2:30 o'clock, and immediately take a dose of five grains of opium. In twenty minutes after, by your watches, you will turn this wheel on the side, one point, and every minute thereafter a point, until the forty-five points, or full revolution of the wheel, have been passed over. This is to shut off the supply of air gradually as the ozone commences to enter through the pores of my body. Have some fresh plaster ready, so that the instant this is accomplished, you can, by quickly opening the little door, pull out the tube from my mouth, and cover the opening with a spoonful of plaster; then, as quickly as possible, withdraw your hand, leaving the pipe inside, and close the door again and seal it with Portland cement. Before the ozone is placed within the case, see that the lower door upon which I lie is sealed by this preparation," and he took a medium-sized bottle, and gave it to Craft. "Now, as regards the compass-needle, I will explain its action." He moved over toward the instrument as he spoke, but suddenly started back upon discovering that the needle no longer pointed to the figures 993. With a troubled look upon his face he gazed upon it. The needle now pointed to 1,007.8, or to a reading of 16 degrees 47.8 minutes.
