Oxygen Necessary for Airmen
at High Altitude
London.—Six days sealed up in a glass case is a ringing forth bear
log on aviation which, if just been carried out by a middle-aged British
university professor, Joseph Barcroft,
P. R. S., reader in physiology at Cambridge university. The question involved was whether it would be possible to calculate the quantity of oxygen necessary to an airman at high altitudes.
The case in which Mr. Barcroft was
about up for six days was specially
needed in a quiet room in the physical laboratory. It was about seven
feet high and about ten feet broad.
The floor, walls and roof were made
of glass, hermetically sealed and divided into two compartments—one
fitted with a lounge chair and table
and the other with a simple bed.
Took Regular Exercise.
At the foot of the bed was a pedal-
tug apparatus consisting of a frame of
had been removed, and a small back
Wheel with a frame attached, to enable
Mr. Barcroft to get some exercise and
cause a certain amount of work to be
done.
During his six days in this case
Mr. Barcroft spent his time in work
relating to the experiments, in taking
exercise on  The bicycle and in sleeping. He was kept under observation day and night to insure his personal safety, college students and others taking their turn to keep watch.
