The essentials of the method of intratracheal insufflation consist, (1)in the introduction deep into the trachea of a elastic tube, the diameter of which has to be much smaller than the lumen of the trachea, and, (2) thedriving through this tube of a nearly continuous stream of air which returns through the space between and the walls of the trachea. The distiguishing features of this method consist in the following two new principles: 1. By bringing the pure air directly to the larger bronchi, and by driving out the vitiated air from these bronchi through the force of the returning air stream, that part of the "death space" is eliminated which is represented by the mouth, pharynx, larynx and trachea. The chief aim of the complicated nervous and muscular mechanisms of respiration is to establish an efficient ventilation, capable of overcoming the obstacles offered by the mentioned "death space." A
