One hundred hours flying, none over lines. 



Physical condition good. 



Run was preceded by 5 minutes' rebreathing during which the oxygen was 

 replenished as consumed. 



The performance was constant until the 22d minute when a retardation oc- 

 curred accompanied by a rise in respiratory rate and pulse pressure. The 

 speed of performance decreased and the number of errors increased until the 

 last minute, when he almost ceased working altogether. He was taken off by 

 the psychologist at 27 : 10 for inefficiency.
