April 26, 1919. No. 6884, second lieutenant, Air Service, observer, twenty- 

 five, single, student, 5 years State Normal; 2 years basketball. 



One hundred and twenty-five hours flying, 40 overseas. No record of com- 

 bats or crashes. Maximal altitude 15,000 feet for 120 minutes. 



Initial performance; accurate, rapid. Disturbed by introduction of mouth- 

 piece but increased speed with practice during the work in normal air. Signifi- 

 cant disturbance at 11 to 12 per cent oxygen in the form of decreased speed. 

 This was more than compensated for by the exercise of greatly increased effort, 

 which later ceased to be effective. Experiment terminated prematurely by 

 clinician.
