762 Experiments 



The cold in the head stops in the night and the cold in the chest 

 disappears. 

 Gas A gives for 10 min. 2.643 liters of C0 2 , that is, for 1 hour 15.858 liters 

 Gas B gives for 10 min. 2.710 liters of CCX, that is, for 1 hour 16.260 liters. 



Experiment CCCXXIV. December 17. Barometric pressure 74 cm.; 

 I begin again the diet of Experiment CCCXXII. 



The urine was collected from noon December 17. 



December 11. Remained at normal pressure. 



Urine from Dec. 17 to Dec. 18 noon .... A 



December 18. At normal pressure, from 2:30 to 3 o'clock, the 

 maximum expiration is 3.76 liters; quiet pulmonary ventilation is 

 6.54 liters per minute; pulse 81. 



At 3 o'clock, began the compression. 



At 3:44, compression +48 cm.; the maximum expiration gives 

 3.96 liters. 



At 4:30, same pressure; pulse 79; pulmonary ventilation 6.74 liters 

 per minute; 8.3 average respirations per minute. 



At 5:12, compression -4-52 cm.; decompression begun.
