Surprising deficiency in oxygen conte,nt of the Antarct,ic atmosphere, too great to be attributable to instrumental technic, was found in t8he course of a series of measurements made at Little America 111 (1st. 78’28 ’ s., long. 163’30 ’ W.) during 1040 and 1941. Oxygen-percentage composition of dry air was found to vary between the wide limits of 20.50 volume percent in summer and 20.80 volume percent in winter, thus indicating a possible seasonal change in the deficiency. “Normal ” middle latitude value is 20.95 volume percent. All of the 25 summertime (December and January) analyses presented here gave values between 20.48 and 20.64 volume pe,rcent for oxygen, with an average of
