Subject noted no difference between the two conditions and was so unconscious of the change that he supposed one of the periods with an increased dead space to be a normal period. Pulse-rate varied somewhat in the different periods, the ranges varying from 6 to 15 beats per minute. The variations in pulse-rate were due to drowsiness and the necessity of waking subject occasionally. Respiration regular in all but fourth period.
