April 28, 1919. No. 6880, First lieutenant, observer, twenty-six, single. 

 Nurseryman. 



One hundred and ten hours flying, 8 combats, one crash, a poor landing; 

 18,500 feet for 10 minutes. 



Physical condition good. 



Run was preceded by 13 minutes' rebreathing during which the oxygen was 

 replenished as consumed. 



He attained high speed and accuracy which continued until the 18th minute, 

 when he began to be less accurate, though speed did not suffer. He was pre- 

 maturely removed at the 31st minute by the clinician. 



This case shows the stimulation that occurs under low oxygen, the greatly 

 increased speed being at the expense of accuracy.
