The patients were kept in a basal state and breathed through a mouth piece into a Tissot spirometer for three and one-half hours, i. e., for fourteen periods of fifteen minutes each. During each period a sample of expired air was taken, its oxygen and carbon dioxide contents were determined and the volume of ventilation recorded; during each period blood was drawn from the finger, and the dextrose and lactate contents were estimated; a sample of arterial blood was taken at the beginning, the middle and the conclusion of the experiment, and the oxygen and carbon dioxide contents and capacities were measured.
